Same as human in the real world, computer also hava an attribute which named hostname. + +### What is hostname ### + +From its manual page, hostname is used to display the system’s DNS name and to display or set its hostname or NIS domain name. So hostname is related to DNS (Domain Name System) or NIS (Network Information System). + +### How to display hostname ### + +Hostname is a pre-installed command in every Linux distribution. You can display your machine hostname by typing hostname in your console. Here’s a sample command and the output : + + $ hostname + ubuntu + +The above command will tell you that the computer name is **ubuntu**. + +### How to set a hostname ### + +Hostname is set when you install you Linux at the first time. There is a step in your installation procedure that your Linux will ask you to fill hostname information. However, **you can do it later** if you want. +To set it your hostname, you can use this command : + + # hostname dev-machine + + $ hostname + dev-machine + +You **need to be root** user or equal to set / change your hostname machine. The # sign is indicated that you are a root user. The above command is telling your computer to set its hostname into **dev-machine**.

This allows for a complete separation between the running of php scripts and Apache. Earlier we had to use modules like mod_fcgid and mod_fastcgi which all had some limitations. Mod_fcgid for example did not properly utilise the process management capability of php-cgi whereas mod_fastcgi is a third party module. + +With the arrival of mod_proxy_fcgi Apache finally gets the ability to neatly talk to external fastcgi process managers making it more efficient at the task. Delegating php requests to external fpm servers greatly reduces the load on web servers like apache resulting into efficient utilisation of machine resources and faster processing speed for users on the other end. Along with all that, php fpm can run opcode caching engines like apc in a very stable manner. + +So in this post, our task is to setup apache + php-fpm using the mod_proxy_fcgi connector. + +### 1.

In this example I used fpm.localhost so that when using that sub domain on localhost, php fpm is used. Its just an example. + +2. **DocumentRoot** - This is the root of this vhost from where the web files shall be served. + +3. **ProxyPassMatch** - This is the directive that tells forward all requests for ".php" files to fcgi server at 127.0.0.1:9000. This is where our php fpm process manager would be running. More on this in the next section. +The fcgi url must contain the exact path to the document root. Otherwise it would say "File Not Found" when requesting for files. + +> ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/var/www/mysite/$1 + +The first parameter is the pattern to match. So all urls that have a ".php" in them followed by an option slash and anything else are matched and the matched part is forwarded to the fcgi server running at 127.0.0.1:9000. + +4. **Require all granted** - After the ProxyPassMatch line we added a section with Require and AllowOverride directives. It is necessary as of Apache 2.4 + +Save the file and enable it using the a2ensite command which saves the effort to create the symlink in sites-enabled directory. + + $ sudo a2ensite mysite + Enabling site mysite. + To activate the new configuration, you need to run: + service apache2 reload + +Now reload apache configuration + + $ sudo service apache2 reload + * Reloading web server apache2 + +That completes the apache configuration.

And edit the fields as explained next. + +1. The first options is the name of the pool. We named it 'www' over here. Name it to anything you like or after the domain name it is going to be used with. 'yoursite' for example. That way it would be easier to remember. + +2. Setup the user and group that this pool will run with. When you are setting up multiple sites/domains/virtualhosts on a server, you would always want to setup separate user accounts and corresponding pool for each of those. This is an essential security measure, so that every pool has privileges of its own user only. + +3. Setup the listening socket. This is the socket on which the master fpm process shall listen for incoming requests. This can be a unix socket or a tcp socket. However [mod_proxy_fcgi does not yet support unix sockets][1], so we are limited to tcp sockets. +Over here its port number 9000 on localhost. + +Now restart fpm + + $ sudo service php5-fpm restart + +Now the new fpm pool should take effect. You can see the new pool process in htop for example. + +### 3. Test the setup ### + +Now that both apache and php fpm are configured and setup, its time to test. Get inside the document root directory and create a php file containing a call to phpinfo() function and open it in your browser. +The "Server API" should be reported as "FPM/FastCGI". + +Now that apache and php are setup, you may want to install other things like APC, mariadb database, phpmyadmin etc. Move around this site to find how-to guides on those. + +### Resources ### + +Check out the following links to learn more +[https://wiki.apache.org/httpd/PHP-FPM][2] + +-------------------------------------------------------------------------------- + +via: http://www.binarytides.com/setup-apache-php-fpm-mod-proxy-fcgi-ubuntu/ + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:https://issues.apache.org/bugzilla/show_bug.cgi?id=54101 +[2]:https://wiki.apache.org/httpd/PHP-FPM \ No newline at end of file From 23a33849d172f2c190dc2e5d329b9e3f8099b0b4 Mon Sep 17 00:00:00 2001 From: DeadFire Date: Tue, 3 Dec 2013 11:05:45 +0800 Subject: [PATCH 10/25] =?UTF-8?q?20131203-3=20=E9=80=89=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...nown Effective Linux Commands – Part IV.md | 185 ++++++++++++++++++ 1 file changed, 185 insertions(+) create mode 100644 sources/10 Lesser Known Effective Linux Commands – Part IV.md diff --git a/sources/10 Lesser Known Effective Linux Commands – Part IV.md b/sources/10 Lesser Known Effective Linux Commands – Part IV.md new file mode 100644 index 0000000000..a5119c9545 --- /dev/null +++ b/sources/10 Lesser Known Effective Linux Commands – Part IV.md @@ -0,0 +1,185 @@ +10 Lesser Known Effective Linux Commands – Part IV +================================================================================ +Continuing the **Lesser Known** series, this fourth article of the series will let you know some useful **funny** and **animated** commands.

controversial issues of government spying and “backdoors” — those nefarious windows into our personal online lives that the public recently discovered in most of the services we use every day. + +我们也探讨了争议性的话题，就是政府部门的监听事件以及‘后门’-那些邪恶的窗口，窥探我们网上的私生活，最近公众发现我们经常使用的大多数服务都有类似的遭遇。 + +Zemlin gave us the skinny on how and why GNU/Linux remains the most secure option for concerned consumers — and why it’s becoming the OS of choice for powering cars, phones, TVs, and all kinds of emerging devices. +Zemlin 为我们解释了 GNU/Linux 为什么以及如何使自身成为内心有些担忧的消费者的最安全的选择。还有就是为什么选择GNU/Linux作为车载操作系统，TVs以及其他新兴设备的操作系统。 + +以下是我们e-mail问答形式的实录。 + +---------- + +**VentureBeat: 安全和隐私成为今年的热门话题，我们听到的谣言，Linus[Torvalds, Linux 创始人]对政府部门是否有安装后门的要求点头称是。** + +**Zemlin**: Linux是否有后门，你是可以知道的. + +世界上所有人都可以看到Linux的每一行代码。这也是linux要比其他操作系统更安全、开源整体要比闭源更安全的原因之一。代码的透明度保证了它的安全性。 + +And for the record: He wasn’t approached. +记录在案的是：后门并没有进入到linux。 + +**VentureBeat: Linux基金会如何保证Linux用户的隐私和自由，使其免于遭受追踪和监视？** + +**Zemlin**: 对此，我们一以贯之。向内核插入违反隐私权和背离自由精神的代码而不被成千上万的开发者注意到，这是很难的。Linux的本性就是自我定制。 + +**VentureBeat: 今年的隐私/安全/监视事件会不会促使, 或者将会促使更多的消费者倾向于Linux，对此你作何感想？** + +**Zemlin**: 世界范围内，我听到人们都在说，“用开源保证隐私是必须的。”的确，那会促使更多的使用者选择Linux。 + +除了他们对linux平台下的隐私和安全持自信、信任的态度以外， 我认为消费者会基于多种原因选择Linux。 +代码的透明性以及开发过程逐渐给予博学和警觉的消费者一个选择，一个会让他们对linux感觉良好的选择。 + +[视频游戏发行商] Valve [及其SteamOS下的工作][1] 正在促使更多的消费者走进Linux，就像逐渐占据主导的Android和其他运行Linux的电子设备一样，比如电视、家电、汽车等，当然还有更多。 + +**VentureBeat: 针对手机的Ubuntu Edge, 对它有何看法？ 对于2014-2015年Linux/Ubuntu手机市场走势，你作何预测？* + +**Zemlin**:我希望看到潜在的有趣的新产品进入市场，尤其是基于Linux的产品。很难说每年哪款产品会成为手机市场的新宠。 + +我认为预测基于Linux的手机将占据主导地位，不算夸大事实。Android, Tizen, Ubuntu, Firefox,等等等等，都显示出Linux可以驱动手机市场的创新，并且为消费者创造新的体验，为开发者和OEMs创造机会。 + +明年令人振奋的及我所关注的，就是，linux和开源界如何把这些设备、对象和服务关联到一起。 + +**VentureBeat: What’s the most exciting use case you’ve seen so far for Linux embedded in automobile systems?** +**VentureBeat: 目前为止，你看到的linux嵌入式车载系统的最令人激动的使用案例是什么？** + +**Zemlin**: 毫无疑问，就是，Cadillac, Tesla, Toyota, Jaguar, Land Rover等都搭建了车载信息娱乐系统。 + +比如，今年赢得了 “年度汽车族”奖项的Tesla Model S，装备了一个17英寸平面、运行着定制Linux的电脑。这真的是太酷了。 + +2014年度汽车族刚刚揭晓 -- Cadillac CTS sedan, 也是使用linux作为车载信息娱乐系统。汽车制造商有能力使用linux进行创新并区别使用这些系统。 + +Linux的成功也能从来自IHS汽车的最新数据上看到，IHS本月报告称，在全球车载信息娱乐市场，基于linux的汽车销量2020年有望达到5.37千万，超过微软和黑莓QNX。 + +Linux基金会协同汽车级Linux工作组在该领域做了许多工作。通过在Linux内核社区，其他开源社区，以及汽车行业，营造一个中立、支持性的环境，针对一些世界上大的汽车制造商如日产，捷豹，路虎，丰田，等等，我们可以帮助其推动汽车linux技术。 + +**VentureBeat: 在硬核开发者市场以外，Linux是如何发展壮大的，尤其是考虑到消费者和游戏玩家？** + +**Zemlin**:可以肯定的是，对游戏玩家来说，今年是linux的一个转折点。Valve, 基于Steam网络平台的一个游戏厂商，在linux上构建并运行所有的源代码和动画。Valve CEO Gabe Newell 称，今年的LinuxCon大会上他们在linux平台运行了198个游戏，随着引进基于linux的Stream，这个数字还会上升。这是Linux和游戏界新趋势的开端。 + +用户每天都在用linux。软件支撑着我们的日常生活。像Google，Facebook还有Twitter等公司，都建立在Linux和开源软件之上。去年10月份LinuxCon欧洲大会上，来自Twitter的Chris Aniszczyk告诉观众： +“Twitter 理所当然完全运行在linux上。为什么你们还需要其他的东西？”(言外之意就是有linux就够了，不需要别的什么东西了。) + +如今Linux驱动着130万台日常用Android手机，每天近60万基于linux的新电视售出。新的家电以及汽车都建立在linux之上。主要交通系统也都在使用linux。最受欢迎的[GoPro 使用linux和开源软件][2]。举不完的例子。 + +Linux和开源理念将会逐渐融入主流消费者的生活。三星使用linux内核以及基于linux的产品充实它的产品线，从电视机到手机，再到家电，等等等等。 + +敬请关注 - 你会看到更多的实例，无不展现出Linux和开源软件以及协同开发在日常生活中发挥越来越大的作用。 + +**VentureBeat: 在你看来，到2014年，免费和开源软件最大的机遇会是什么？** + +**Zemlin**: 我们已经谈到游戏和电子设备，但是企业将会继续为linux呈现更多的机会。云计算的兴起为开发者带来新的机遇和挑战。你试着去找找没有运行在linux上的公共云。 + +软件定义的网络实现将成为2014年的主要活动之一。人们并没有期望着软件定义网络以及网络功能虚拟化变得多么大。想想吧。数十亿美元花费在硬件上，交换机，路由，负载均衡器，防火墙等等。这些都抽象成了软件。更更重要的是,它是在开源软件的基础架构甜蜜点OSS层被抽象。我认为你会看到，像OpenDaylight项目以及其他项目，在2014年都会有大的突破。 + +当然，这只是实现协同发展的大趋势的一部分，你的读者应该会对此感兴趣。我的推测是再过一个20年，几乎所有的基础软件都会议协同开发的方式进行构建。2014年开发者需要学习如何以协同方式构建软件，要学会如何参与开源项目并且贡献代码。如果开发者能够理解协同开发和开源的原则和理念，那么他们职业生涯中的机遇将会是无穷的。 + +参与到linux的世界中来，这是一个激动人心的时刻。从智能手表到电视机，到汽车，所有你能想到的，Linux成为事实上的平台。 +-------------------------------------------------------------------------------- + +via:

privacy has been the hottest topic this year, bar none. We’ve heard rumors that Linus [Torvalds, Linux creator] OK’d a Linux backdoor for the government.** - -**Zemlin**: If there were a backdoor in Linux, you’d know it. - -The whole world can see every line of code in Linux. This is one of the reasons Linux is more secure than other operating systems and why open-source software overall is a safer than closed software. The transparency of the code ensures it’s secure. - -And for the record: He wasn’t approached. - -**VentureBeat: How committed is the foundation to preserving Linux users’ privacy and freedom from tracking/surveillance?** - -**Zemlin**: As committed as we have always been. It’s very difficult to insert something into the kernel that would violate privacy and freedom without thousands of developers noticing. The nature of Linux is that it’s self-policing. - -**VentureBeat: Do you think there’s any chance that this year’s privacy/security/surveillance issues has driven or will drive more consumers toward Linux?** - -**Zemlin**: Around the world, I am hearing people say, “Using open source is a critical to ensure privacy.” So yes, I think that will drive more users people to Linux. - -I also think more consumers are being driven toward Linux for a variety of reasons, in addition to the confidence and trust they have about privacy and security related to the platform. The transparency of the code and development process gives increasingly knowledgeable and aware consumers an option they feel good about. - -[Video game publisher] Valve and [its work on SteamOS][1] is driving more consumers to Linux, as is the ongoing dominance of Android and other consumer devices that run Linux — from televisions to appliances, cars, and more. - -**VentureBeat: Do you have any thoughts on the Ubuntu Edge for phones? Where do you see the market for Linux/Ubuntu phones going in 2014-2015?** - -**Zemlin**: I like seeing potentially interesting new products go to market, especially when they’re Linux-based. It is hard to predict what product will produce a big hit in the phone market from year to year. - -I don’t think it is a stretch to predict phones based on Linux will dominate. Android, Tizen, Ubuntu, Firefox, and more show that Linux can drive innovation in the mobile market and create new experiences for consumers and market opportunities for developers and OEMs. - -What’s exciting about the year ahead, and what I’ll be watching, is how Linux and open source will help connect all of these devices, objects, and services together. - -**VentureBeat: What’s the most exciting use case you’ve seen so far for Linux embedded in automobile systems?** - -**Zemlin**: No question it’s the in-vehicle-infotainment systems being built by Cadillac, Tesla, Toyota, Jaguar, Land Rover, and others. - -For example, the Tesla Model S, which won the Motor Trend Car of the Year [honor] in 2013, features a 17-inch flat-screen computer running a custom-built Linux OS. This is really, really cool stuff. - -And the 2014 Motor Trend Car of the Year was just revealed — the Cadillac CTS sedan — and it also uses Linux for its in-vehicle-infotainment system. Car makers are able to innovate and differentiate with these systems using Linux. - -The success of Linux here can be seen in the latest numbers from IHS Automotive, which reported this month that sales of automotive Linux are expected to rise to 53.7 million units in 2020, passing Microsoft and Blackberry QNX in the global automotive infotainment market. - -The Linux Foundation does a lot of work in this area with its Automotive Grade Linux workgroup. By hosting a neutral, supportive environment among the Linux kernel community, other open-source communities, and the automotive industry, we’re able to help advance automotive Linux technologies among some of the world’s largest automakers including Nissan, Jaguar, Land Rover, Toyota, and more. - -**VentureBeat: How is Linux growing beyond the hardcore developer market, especially with regard to consumers and gamers?** - -**Zemlin**: This year has been a turning a point for Linux with gamers for sure. Valve, the gaming company behind the Steam web platform for Linux, builds and runs all of its source code and animation on Linux. Valve’s CEO Gabe Newell reported at LinuxCon this year that they’re running 198 games on Linux, and with the introduction of the Linux-based Steam, that number will only continue to go up. This is the beginning of a new trend for Linux and gaming. - -Consumers use Linux every day. It is the software that runs our lives. Companies like Google, Facebook, and Twitter are built on Linux and open-source software. At our LinuxCon Europe conference in October, Twitter’s Chris Aniszczyk told the audience: “Twitter is of course all running on Linux. Why would you need anything else?” - -Linux now powers the 1.3 million Android phones that are activated daily, and most of the nearly 600,000 new TVs sold every day. New appliances and cars are being built with Linux. Major transportation systems use the operating system. The superpopular [GoPro uses Linux and open source][2]. The examples are endless. - -And Linux and open source will just keep reaching more into mainstream consumer life. Samsung uses the Linux kernel and Linux-based products throughout its product line, from TVs to phones to home appliances and more. - -Stay tuned — you’ll see more coming that illustrates the growing role of Linux and open source software and collaborative development in everyday life. - -**VentureBeat: What are the biggest opportunities for free and open-source software in 2014, in your opinion?** - -**Zemlin**: We’ve talked about gaming and consumer devices, but the enterprise continues to present even more opportunity for Linux. The rise of cloud computing is creating new challenges for developers and new opportunities for growth. Try to find a public cloud that’s not running Linux. - -The realization of years of promise in software defined networking will be one of the major stories of 2014. People don’t appreciate how big software defined networking and network function virtualization will become. Think about it. Billions of dollars are spent on hardware based switches, routers, load balancers, firewalls, etc.; this is all being abstracted into software. More importantly it is being abstracted via open source software in the sweet spot for OSS which is at this infrastructure layer. I think you’ll see projects like OpenDaylight and others have a big breakout year in 2014. - -Of course, this is all part of a broader trend towards collaborative development, which should be of interest to your readers. I’d predict that in another decade nearly all of infrastructure software will be built collaboratively. Developers in 2014 need to learn how to build software collaboratively and how to work on and contribute to open source software projects. Their career opportunities will be endless if they understand the principles of collaborative development and open source software. - -It’s a thrilling time to be involved in Linux. It’s become the de facto platform to go to for everything from smart watches to TVs to automobiles, you name it. - --------------------------------------------------------------------------------- - -via: http://venturebeat.com/2013/11/26/linux-chief-open-source-is-safer-and-linux-is-more-secure-than-any-other-os-exclusive/ - -译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 - -[1]:http://venturebeat.com/2013/09/23/steamos-valves-linux-based-operating-system-for-the-tv-and-living-room/ -[2]:http://gopro.com/support/open-source \ No newline at end of file From 9525245bf5c0545f672ad46e0acc1bffeec593db Mon Sep 17 00:00:00 2001 From: carolinewuyan <309866211@qq.com> Date: Tue, 3 Dec 2013 16:39:17 +0800 Subject: [PATCH 17/25] =?UTF-8?q?=E5=B7=B2=E6=A0=A1=E5=AF=B9?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...

It provides a snapshot of the current processes along with detailed information like user id, cpu usage, memory usage, command name etc. It does not display data in real time like top or htop commands. But even though being simpler in features and output it is still an essential process management/monitoring tool that every linux newbie should know about and learn well. - -In this post we are going to revise the basics of using the ps command to check the processes and filter and sort them in different ways to suit better. - -### Note on syntax ### - -The ps command comes with an unusual set of 2 syntax styles. That is BSD and UNIX both. New users are often confused with and mis-interpret the two styles. So here is some basic info to get it clear before moving on. - -> Note : "ps aux" is not the same as "ps -aux". For example "-u" is used to show process of that user. But "u" means show detailed information. - -BSD style - The options in bsd style syntax are not preceded with a dash. - - ps aux - -UNIX/LINUX style - The options in linux style syntax are preceded by a dash as usual. - - ps -ef - -It is okay to mix both the syntax styles on linux systems.

IBM i shops were hesitant to use it, and vendors were afraid to adopt it. But with so much of the computing world now running on open source, the aversion to open source has gradually melted away, and it has steadily crept into use among large corporations, and the IBM i world too. + +It is tough to measure the adoption of open source software, which flows freely across networks by its very nature. Nobody requires you to register to use open source software, and there's no central clearinghouse of information about open source software. + +However, recent surveys and audits point to greater adoption of open source across all industries. Open source software components are widely used in in the financial services industry, according to Julian Brook, associate director at SQS Software, which conducts software quality audits for financial software vendors. "I would say that, arguably, open source is used in every organization that is developing software, especially in the financial services world," Brook [told Out-Law.com recently][1]. + +Governmental agencies lead the way in use of open source software, according to [Black Duck Software][2]'s 2013 Future of Open Source survey. More than 35 percent of government representatives queried for the survey say they use open source, followed by medical (15.2 percent), media (13 percent), financial (8.8 percent), and retail (5.9 percent). You can view more of the survey at [Slideshare][3]. + +Increasingly, users are adopting open source software because they expect higher software quality and security with open source, according to surveys like those from Black Duck. That's very interesting, because for many years, open source software was largely avoided for those two very reasons. + +These are opinion surveys, mind you. They're not necessarily reflections of actual reality. But it is clear than many of the shortcomings that people previously associated with open source software products are disappearing. And slowly but surely, this trend is bleeding over into the competitive world of IBM i software, too. + +### Open Source Impacts On IBM i ### + +The IBM i server is one of the last great bastions of proprietary technology in a world heading in the direction of open source. IBM does not share with the world the guts of the IBM i OS and the System Licensed Internal Code (SLIC) it runs on. You can take what access IBM provides developers to the machine, or you can leave it, but you can't get access to the internals. + +What goes on above the OS and SLIC layers is another matter entirely. We're not seeing a big influx of open source software in the world of ERP and business applications. But in many other software categories, open source options are proliferating. + +One IBM i proponent of open source software is [Raz-Lee][4]. The security software vendor, which relies on the open source [ClamAV][5] offering to power its IBM i-based anti-virus offering, called iSecurity Anti-Virus, says ClamAV had an update for an evolving security threat--the W32/Autorun.worm.aaeh Trojan Horse--months before its competitor had updated the signature library for its IBM i-based antivirus offering. + +"It turns out that ClamAV has been handling this threat . . . as of about eight to nine months ago," Raz-Lee vice president of business development Eli Spitz wrote in an email to IT Jungle last month. "In fact, one of our technicians here at Raz-Lee actually added his own unofficial signature to ClamAV's database before ClamAV included their formal signature for this virus." + +Another IBM i software vendor using open source tools is [Arpeggio Software][6] . The Atlanta, Georgia-based company uses lots of open source components in its various IBM i utilities, which aren't available under an open source license, but which Arpeggio gives away and then charges customers to get technical support, a common approach taken by commercial open source vendors. + +Arpeggio's latest offering, called ARP-DROP, uses the open source OAuth authentication method to help secure communication channels between IBM i servers and [DropBox][7] service running on the Internet. It also uses the OpenSSH encryption technology with ARP-SFTP client for IBM i. Arpeggio's founders (who also founded Trailblazer Systems, now part of [Liaison Technologies][8]) acknowledge that IBM i professionals could adopt the same open source tools to write similar tools. But they argue that Arpeggio does it better, so why not adopt their free tools and save yourself the time? + +In many cases, an IBM i shop's first conscious exposure to open source is the server side scripting language PHP. IBM and [Zend Technology][9] have worked for years to make PHP run well on IBM i, and Zend's entry-level PHP runtime is shipped along with every Power Systems server and IBM i license. + +One of the most popular PHP applications that run on IBM i servers is [SugarCRM][10]. Representatives with the Cupertino, California, company recently said that it has nearly 1,000 customers running the CRM software on IBM i servers. This includes paid enterprise licenses along with free community edition licenses. + +### Fighting Perceptions ### + +Most IBM i shops are big users of IBM i software, whether they know it or not. Some of the biggest, most important IT infrastructure components come from open source, including the Apache Web server, the Linux OS, the Java and PHP programming languages, the MySQL database, and the Eclipse development environment. + +There's no reason not to call open source "commercial grade" anymore, Raz-Lee's Spitz said. "A few weeks ago Sourcefire, the owners of ClamAV, was purchased by [Cisco Systems][11]. That's obviously a 'certification' by a large commercial organization for open source software. So open source anti-virus software seems to be valuable to a multi-national company." + +While open source software is making inroads in the IBM i community, it still has a ways to go to match the momentum that open source enjoys in the IT market as a whole. "It seems that the IBM i community is often less involved with open source and is not exposed to its importance and prevalence in the current computing area," Spitz said. "In many cases, open source is the 'playground' of very large companies who join to create a better arena for us all." + +As the corporations of the world gradually becomes amenable to open source, the IBM i community will have no choice but to follow. + +-------------------------------------------------------------------------------- + +via: http://www.itjungle.com/tfh/tfh120213-story01.html + +译者：[译者ID](https://github.com/译者ID) 校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创翻译，[Linux中国](http://linux.cn/) 荣誉推出 + +[1]:http://www.out-law.com/en/articles/2013/september/open-source-code-use-within-financial-services-organisations-visibility-only-50-at-best-says-software-quality-expert/ +[2]:http://www.blackducksoftware.com/ +[3]:http://www.slideshare.net/blackducksoftware/the-2013-future-of-open-source-survey-results +[4]:http://www.razlee.com/ +[5]:http://www.clamav.net/ +[6]:http://www.arpeggiosoftware.com/ +[7]:http://www.dropbox.com/ +[8]:http://www.liaison.com/ +[9]:http://www.zend.com/ +[10]:http://www.sugarcrm.com/ +[11]:http://www.cisco.com/ \ No newline at end of file From 7b887508628f066beee4601557295861b448557b Mon Sep 17 00:00:00 2001 From: carolinewuyan <309866211@qq.com> Date: Wed, 4 Dec 2013 16:31:08 +0800 Subject: [PATCH 23/25] =?UTF-8?q?=E5=B7=B2=E6=A0=A1=E5=AF=B9?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- ...
