Back in 2000, Microsoft released their Small Business Server. This product changed the way many people viewed how technology could function within the realm of business. Instead of having multiple machines handle different tasks, you could deploy a single server which would handle email, calendaring, file sharing, directory services, VPN, and a whole lot more. For many of small businesses, this was a serious boon, but for some the cost of the Windows SMB was prohibitive. For yet others, the idea of relying on such a server, designed by Microsoft, simply wasn’t an option.
|
||||
|
||||
For that last group, there are alternatives. In fact, within the realm of Linux and open source, you can choose from several solid platforms that can serve your small business as a one-stop server shop. If your small business has between 10 and 50 employees, the all-in-one server might be the ideal solution to meet your needs.
|
||||
|
||||
Here, I’ll look at two Linux all-in-one servers, so you can see if one of them is the perfect match for your company.
|
||||
|
||||
Remember, these servers are not, in any way, suited for big business or enterprise. Larger companies cannot rely on the all-in-one server simply because a single server cannot take the load expected within the realm of enterprise needs. With that said, here’s what SMBs can expect from a Linux all in one.
|
||||
|
||||
### ClearOS
|
||||
|
||||
[ClearOS][1] was originally released in 2009, under the name ClarkConnect, as a router and gateway distribution. Since then, ClearOS has added all the features necessary to define it as an all-in-one server. ClearOS offers more than just a piece of software. You can also purchase a [ClearBox 100][2] or [ClearBox 300][3]. These servers ship complete with ClearOS and are marketed as IT in a box. Check out the feature comparison/price matrix [here][4].
|
||||
|
||||
For those with hardware already in-house, you can download one of the following:
|
||||
|
||||
- [ClearOS Community][5] — The community (free) edition of ClearOS
|
||||
|
||||
- [ClearOS Home][6] — Ideal for home offices (details on features and subscription costs, see here)
|
||||
|
||||
- [ClearOS Business][7] — Ideal for small businesses (details on features and subscription costs, see here)
|
||||
|
||||
What do you get with ClearOS? You get a business-class server with a single, elegantly designed web interface. What is unique about ClearOS is that you will get plenty of features in the base server; beyond that, you must add on features from the [Clear Marketplace][8]. From within the Marketplace, you can install free or paid apps that extend the feature set of the ClearOS server. Here you’ll find add-ons for Windows Server Active Directory, OpenLDAP, Flexshares, Antimalware, Cloud, Web access control, Content filtering, and much more. You’ll even find some third-party add-ons such as Google Apps Synchronization, Zarafa Collaboration Platform, and Kaspersky Anti-virus.
|
||||
|
||||
ClearOS is installed like any other Linux distribution (based on Red Hat’s Anaconda installer). Once the install is complete, you will be prompted to set up the networking interface as well as presented with the address to point your browser (on the same network as the ClearOS server). The address will be in the form:
|
||||
|
||||
[https://IP_OF_CLEAROS_SERVER:81][9]
|
||||
|
||||
Where IP_OF_CLEAROS_SERVER is the actual IP address of the server. NOTE: When you first point your browser to the server, you will receive a “Connection is not private” warning. Proceed on to the address so you can continue the setup.
|
||||
|
||||
When the browser finally connects, you will be prompted for the root user credentials (you set the root user password up during initial installation). Once authenticated, you will be presented with the ClearOS setup wizard (Figure 1 above).
|
||||
|
||||
Click the Next button to begin the process of setting up your ClearOS server. The wizard is self-explanatory and, in the end, you will be asked which version of ClearOS you want to use. Click either Community, Home, or Business. Once selected, you will be required to register for an account. Once you’ve created an account and registered the server, you can then move on to updating the server, configuring the server, and adding modules from the marketplace (Figure 2).
|
||||
|
||||
|
||||
|
||||
>Figure 2: Installing modules from the marketplace.
|
||||
|
||||
At this point, you are ready to start digging deep into the configuration of your ClearOS small business server.
|
||||
|
||||
### Zentyal
|
||||
|
||||
[Zentyal][10] is a Ubuntu-based small business server that was, at one point, distributed under the name eBox. Zentyal offers plenty of servers/services to fit your SMB needs:
|
||||
|
||||
- Email — Webmail; Native MS Exchange protocols and Active Directory support; Calendars and contacts; Mobile device email sync; Antivirus/antispam; IMAP, POP, SMTP, CalDAV, and CardDAV support
|
||||
|
||||
- Domain & Directory — Central domain directory management; Multiple organization units; Single sign-on authentication; File sharing; ACLs, Advanced domain management, Printer management
|
||||
|
||||
- Networking & Firewall — Static and DHCP interfaces; Objects & services; Packet filter; Port forwarding
|
||||
|
||||
- Infrastructure — DNS; DHCP; NTP; Certification authority; VPN
|
||||
|
||||
- Firewall
|
||||
|
||||
The installation of Zentyal is very much like that of Ubuntu Server—it’s text based and quite simple: Boot up the install media, make a few quick selections, and wait for the installation to complete. Once the initial, text-based, installation is finished, you are presented with the GUI desktop where a wizard will appear for package selection. Select all the packages you want to install and allow the installer to finish the job.
|
||||
|
||||
Finally, you can log into your Zentyal server via the web interface (point your browser to [https://IP_OF_SERVER:8443][11] — where IP_OF_SERVER is the LAN address of the Zentyal server) or use the standalone, desktop GUI to administer the server (Zentyal includes quick access to an Administrator and User console as well as a Zentyal Administration console). When all systems have been saved and started, you will be presented with the Zentyal Dashboard (Figure 3).
|
||||
|
||||
|
||||
|
||||
>Figure 3: The Zentyal Dashboard in action.
|
||||
|
||||
The Dashboard allows you to control all aspects of the server, such as updating, managing servers/services, and getting a quick status update of the server. You can also go into the Components area and install components that you opted out of during installation or update the current package list. Click on Software Management > System Updates and select what you want to update (Figure 4), then click the UPDATE button at the bottom of the screen.
|
||||
|
||||
|
||||
|
||||
>Figure 4: Updating your Zentyal server is simple.
|
||||
|
||||
### Which Server Is Right for You?
|
||||
|
||||
The answer to this question depends on what you need. Zentyal is an amazing server that does a great job running your SMB network. If you need a bit more, such as groupware, your best bet is to go with ClearOS. If you don’t need groupware, either server will do an outstanding job.
|
||||
|
||||
I highly recommend installing both of these all-in-one servers to see which will best serve your small company needs.

两个杰出的一体化Linux服务器
|
||||

|
||||
|
||||
回到2000年，微软发布小型商务服务器。这个产品改变了很多人们对科技在商务领域的看法。你可以部署一个单独的服务器，它能处理邮件，日历，文件共享，目录服务，VPN，以及更多，而不是很多机器处理不同的任务。对很多小型商务来说，这是非常好的恩惠，但是Windows SMB的一些花费是昂贵的。对于其他人，微软设计的依赖于一个服务器的想法，根本不是一个选项。
|
||||
|
||||
对于最近的用户群，有些替代品。事实上，在Linux和开源领域里，你可以选择许多稳定的平台，它可以作为一站式服务商店服务于你的小型企业。如果你的小型企业有10到50员工，一体化服务器也许是你所需的理想方案。
|
||||
|
||||
这里，我将要看看两个Linux一体化服务器，所以你可以查看他们哪个能完美适用于你的公司。
|
||||
|
||||
记住，这些服务器不能，以任何方式，适用于大型商务或企业。大公司无法依靠一体化服务器，仅仅是因为一台服务器不能负荷在企业内所需的企望。除此之外，这就是小型企业可以从Linux一体化服务器期待什么。
|
||||
|
||||
### ClearOS
|
||||
|
||||
[ClearOS][1]是在2009年在ClarkConnect下发行的，作为一个路由和网关的分支。从那以后，ClearOS已经增加了所有一体化服务器必要的特性。CearOS提供的不仅仅是一个软件。你可以购买一个[ClearBox 100][2] 或[ClearBox 300][3]。这些服务器搭载完整的ClearOS作为一个IT设备被销售。在[这里][4]查看特性比对/价格矩阵。
|
||||
|
||||
家里已经有这些硬件，你可以下载这些之一：
|
||||
|
||||
- [ClearOS社区][5] — 社区（免费）版的ClearOS
|
||||
|
||||
- [ClearOS家庭][6] — 理想的家庭办公室（详细的功能和订阅费用，见这里）
|
||||
|
||||
- [ClearOS商务][7] — 理想的小型商务（详细的功能和订阅费用，见这里）
|
||||
|
||||
使用ClearOS你得到了什么？你得到了一个单机的业务合作服务器，设计精美的网页。ClearOS独特的是什么？你可以在基础服务中得到很多特性。除了这个，你必须从 [Clear Marketplace][8]增加特性。在市场上，你可以安装免费或付费的应用程序，扩展集的ClearOS服务器的特性。这里你可以找到附加的Windows服务器活动目录，OpenLDAP，Flexshares，Antimalware，云，Web访问控制，内容过滤，还有更多。你甚至可以找到一些第三方组件像谷歌应用同步，Zarafa合作平台，卡巴斯基杀毒。
|
||||
|
||||
ClearOS的安装像其他Linux发行版（基于红帽的Anaconda安装程序）。安装完成后，系统将提示您设置网络接口就是提供你浏览器访问的地址（与ClearOS服务器在同一个网络里）。地址格式如下：
|
||||
|
||||
[https://IP_OF_CLEAROS_SERVER:81][9]
|
||||
|
||||
IP_OF_CLEAROS_SERVER就是服务器的真实IP地址。注：当你第一次在浏览器访问这个服务器时，你将收到一个“Connection is not private”的警告。继续访问这个地址你才能继续设置。
|
||||
|
||||
当浏览器连接上，就会提示你root用户认证（在初始化安装中你设置的root用户密码）。一通过认证，你将看到ClearOS的安装向导（上图1）
|
||||
|
||||
点击下一步按钮，开始设置你的ClearOS服务器。这个向导无需加以说明，在最后还会问你想用那个版本的ClearOS。点击社区，家庭，或者商业。一旦选择，你就需要注册一个账户。创建了一个账户注册了服务器后，你可以开始更新服务器，配置服务器，从市场添加模块（图2）。
|
||||
|
||||
|
||||
|
||||
>图2: 从市场安装模块。
|
||||
|
||||
此时，你已经准备开始深入挖掘配置你的ClearOS小型商务服务器了。
|
||||
|
||||
### Zentyal
|
||||
|
||||
[Zentyal][10]是一个基于Ubuntu的小型商务服务器，现在，发布在eBox域名下。Zentyal提供了大量的服务器/服务来适应你的小型商务需求：
|
||||
|
||||
- 电子邮件 — 网页邮件；原生微软邮件协议和活动目录支持；日历和通讯录；手机设备电子邮件同步；反病毒/反垃圾；IMAP，POP，SMTP，CalDAV，和CardDAV支持。
|
||||
|
||||
- 域和目录 — 核心域目录管理；多个组织单元；单点登录身份验证；文件共享；ACLs，高级域名管理，打印机管理。
|
||||
|
||||
- 网络和防火墙 — 静态和DHCP接口；对象和服务；包过滤；端口转发。
|
||||
|
||||
- 基础设施 — DNS；DHCP；NTP；认证中心；VPN。
|
||||
|
||||
- 防火墙
|
||||
|
||||
安装Zentyal很像Ubuntu服务器的文本安装而且很简单：启动安装镜像，做一些选择，等待安装完成。一旦初始化，完成基于文本安装，就提供给你桌面GUI，向导程序提供选择包。选择所有你想安装的包，让安装程序完成这些工作。
|
||||
|
||||
最终，你可以通过网页接口来访问Zentyal服务器（浏览器访问[https://IP_OF_SERVER:8443][11] - IP_OF_SERVER是Zentyal服务器的内网地址）或使用独立的桌面GUI来管理服务器（Zentyal包括快速访问管理员和用户控制台就像Zentyal管理控制台）。当全部系统已经保存开启，你将看到Zentyal面板（图3）。
|
||||
|
||||
|
||||
|
||||
>图3: Zentyal活动面板.
|
||||
|
||||
这个面板允许你控制服务器所有方面，比如更新，管理服务器/服务，获取服务器的敏捷状态更新。您也可以进入组件领域，然后安装部署过程中选择出来的组件或更新当前的软件包列表。点击 软件管理 > 系统更新 并选择你想更新的（图4），然后在屏幕最底端点击更新按钮。
|
||||
|
||||
|
||||
|
||||
>图4: 更新你的Zentyal服务器很简单。
|
||||
|
||||
### 那个服务器适合你？
|
||||
|
||||
回答这个问题要看你有什么需求。Zentyal是一个不可思议的服务器，它很好的胜任于你的小型商务网络中。如果你需要更多，如组合软件，你最好赌在ClearOS上。如果你不需要组合软件，任意的服务器将表现杰出的工作。
|
||||
|
||||
我强烈建议安装这两个一体化的服务器，看看哪个是你的小公司所需的最好服务。
