With this tool, you will not only be able to browse the data mentioned earlier, but also parse the web server logs to dig for further data as well - and **all of this within a terminal window in real time**. Since as of today [most web servers][2] use either a Debian derivative or a Red Hat based distribution as the underlying operating system, I will show you how to install and use GoAccess in Debian and CentOS. - -### Installing GoAccess on Linux ### - -In Debian, Ubuntu and derivatives, run the following command to install GoAccess: - - # aptitude install goaccess - -In CentOS, you'll need to enable the [EPEL repository][3] and then: - - # yum install goaccess - -In Fedora, simply use yum command: - - # yum install goaccess - -If you want to install GoAccess from the source to enable further options (such as GeoIP location), install [required dependencies][4] for your operating system, and then follow these steps: - - # wget http://tar.goaccess.io/goaccess-0.8.5.tar.gz - # tar -xzvf goaccess-0.8.5.tar.gz - # cd goaccess-0.8.5/ - # ./configure --enable-geoip - # make - # make install - -That will install version 0.8.5, but you can always verify what is the latest version in the [Downloads page][5] of the project's web site. - -Since GoAccess does not require any further configurations, once it's installed you are ready to go. - -### Running GoAccess ### - -To start using GoAccess, just run it against your Apache access log. - -For Debian and derivatives: - - # goaccess -f /var/log/apache2/access.log - -For Red Hat based distros: - - # goaccess -f /var/log/httpd/access_log - -When you first launch GoAccess, you will be presented with the following screen to choose the date and log format. As explained, you can toggle between options using the spacebar and proceed with F10. As for the date and log formats, you may want to refer to the [Apache documentation][6] if you need to refresh your memory. - -In this case, Choose Common Log Format (CLF): - -![](https://farm8.staticflickr.com/7422/15868350373_30c16d7c30.jpg) - -and then press F10. You will be presented with the statistics screen. For the sake of brevity, only the header, which shows the summary of the log file, is shown in the next image: - -![](https://farm9.staticflickr.com/8683/16486742901_7a35b5df69_b.jpg) - -### Browsing Web Server Statistics with GoAccess ### - -As you scroll down the page with the down arrow, you will find the following sections, sorted by requests. The order of the categories presented here may vary depending on your distribution or your preferred installation method (from repositories or from source): - -1. Unique visitors per day (HTTP requests having the same IP, same date and same agent are considered an unique visit) - -![](https://farm8.staticflickr.com/7308/16488483965_a439dbc5e2_b.jpg) - -2. Requested files (Pages-URL) - -![](https://farm9.staticflickr.com/8651/16488483975_66d05dce51_b.jpg) - -3. Requested static files (e.g., .png, .js, etc) - -4. Referrers URLs (the URLs where each request came from) - -5. HTTP 404 Not Found response code - -![](https://farm9.staticflickr.com/8669/16486742951_436539b0da_b.jpg) - -6. Operating Systems - -7. Browsers - -8. Hosts (client IPs) - -![](https://farm8.staticflickr.com/7392/16488483995_56e706d77c_z.jpg) - -9. HTTP status codes - -![](https://farm8.staticflickr.com/7282/16462493896_77b856f670_b.jpg) - -10. Top referring sites - -11. Top keyphrases used on Google's search engine - -If you also want to inspect the archived logs, you can pipe them to GoAccess as follows. - -For Debian and derivatives: - - # zcat -f /var/log/apache2/access.log* | goaccess - -For Red Hat based distributions: - - # cat /var/log/httpd/access* | goaccess - -Should you need a more detailed report of any of the above (1 through 11), press the desired section number and then O (uppercase o) to bring up what is called the Detailed View. The following image shows the output of 5-O (press 5, then press O): - -![](https://farm8.staticflickr.com/7382/16302213429_48d9233f40_b.jpg) - -To display GeoIP location information, open the Detail View in the Hosts section, as explained earlier, and you will see the location of the client IPs that performed requests to your web server: - -![](https://farm8.staticflickr.com/7393/16488484075_d778aa91a2_z.jpg) - -If your system has not been very busy lately, some of the above sections will not show a great deal of information, but that situation can change as more and more requests are made to your web server. - -### Saving Reports for Offline Analysis ### - -There will be times when you don't want to inspect your system's stats in real time, but save it to a file for offline analysis or printing. To generate an HTML report, simply redirect the output of the GoAccess commands mentioned earlier to an HTML file. Then just point your web browser to the file to open it. - - # zcat -f /var/log/apache2/access.log* | goaccess > /var/www/webserverstats.html - -Once the report is displayed, you will need to click on the Expand link to show the detail view on each category: - -![](https://farm9.staticflickr.com/8658/16486743041_bd8a80794d_o.png) - -注释：youtube视频 - - -As we have discussed throughout this article, GoAccess is an invaluable tool that will provide you, as a system administrator, with HTTP statistics in a visual report on the fly. Although GoAccess by default presents its results to the standard output, you can also save them to JSON, HTML, or CSV files. This converts GoAccess in an incredibly useful tool to monitor and display statistics of a web server. - --------------------------------------------------------------------------------- - -via: http://xmodulo.com/interactive-apache-web-server-log-analyzer-linux.html - -作者：[Gabriel Cánepa][a] -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 - -[a]:http://xmodulo.com/author/gabriel -[1]:http://goaccess.io/ -[2]:http://w3techs.com/technologies/details/os-linux/all/all -[3]:http://xmodulo.com/how-to-set-up-epel-repository-on-centos.html -[4]:http://goaccess.io/download#dependencies -[5]:http://goaccess.io/download -[6]:http://httpd.apache.org/docs/2.4/logs.html diff --git a/translated/tech/20150215 How to analyze and view Apache web server logs interactively on Linux.md b/translated/tech/20150215 How to analyze and view Apache web server logs interactively on Linux.md new file mode 100644 index 0000000000..c65b78f21e Binary files /dev/null and b/translated/tech/20150215 How to analyze and view Apache web server logs interactively on Linux.md differ
