Apache configuration/zh

Apache是MediaWiki最常用的web服务器.

作为 Apache 模块的 PHP
MediaWiki is written to use PHP as an Apache module. Your PHP is probably configured as a module if you start with URLs like this: example.com/index.php/Main_Page

You can check which configuration and version of PHP you have by viewing your wiki's Special:Version page, or with phpinfo.

Red Hat / 基于 Fedora 的 Linux
安装 PHP:


 * 1) yum install php php-xml

重新加载 httpd：


 * 1) service httpd reload

基于 Debian 的 Linux
安装 apache2 php5 模块：


 * 1) apt-get install apache2 libapache2-mod-php5 php5-cli php-apc php5-mcrypt

在Ubuntu 16.04.2 LTS中

 * 1) sudo apt-get install libapache2-mod-php

启用 apache2 php5 模块：


 * 1) a2enmod php5

重启 Apache：


 * 1) service apache2 restart

作为 CGI 的 PHP
如果PHP以CGI方式运行，您将默认使用“不美观的”URL，但可以参考进行修改.

CGIWrap
If you have your own server running Apache and are running PHP as CGI, you can install CGIWrap. This tool enables you to run the Apache server as a different user for CGIs.

That way, you can create a new user for your MediaWiki pages. Installing CGIWrap is beyond the scope of this document, especially since you must compile it accordingly to your own server. However, as a quick guideline, you can follow these rules:

useradd -M -s /sbin/nologin wikiuser
 * 创建一个Wikimedia用户
 * Have a cgi-bin folder, containing CGIWrap (example in /home/myuser/cgi-bin). Once everything is configured, keep only cgiwrap, move the debug versions to another folder if you ever need it. Your cgiwrap file should be accessible only to Apache (chown and chmod accordingly).

ln -s /home/myuser/public_html/wiki /home/myuser/cgi-bin/wikilink AddHandler php-wrapper .php Action php-wrapper /cgi-bin/cgiwrap/wikiuser/wikilink
 * Inside the cgi-bin folder, create a symbolic link to the Wikimedia root.
 * 在您的 wiki 的 .htaccess 文件中，添加以下定义：
 * Finally, chown and chmod all the .php files of your Wikimedia folder to be accessible solely by wikiuser.

The files will be accessible as usual. You do not need to specify in your path any cgi-bin, as this is transparently taken care of for you.

I strongly suggest you start out with /cgi-bin/cgiwrapd/... as your php-wrapper, as it will precisely show what is currently working. I also strongly suggest you do not delete your CGIWrap source folder until everything works perfectly as this is a real trial and error process, taking a long time. However, it's all worth your time as your MediaWiki will be run in its own separate process, in its own uid, without being able to interfere any other uid. Inverse is also true, except for root, that can read anything anywhere.

mod_alias / mod_rewrite
The recommended method of beautifying URLs involves mod_alias. Other methods use mod_rewrite instead.

mod_security
has been known to cause problems with MediaWiki. If you get errors seemingly at random, check your error log to see whether it is causing problems.

VisualEditor and Subpages
In order to prevent errors contacting the Parsoid server,  must be added to the wiki's VirtualHost config block (or to the general server config if VirutalHosts are not used).

线程堆栈大小
The stack size for for each Apache thread is configurable and the default varies on different operating systems. To run MediaWiki on Windows environments it may be necessary to increase the stack size (if there are problems), as the 1MB default is small and can cause stack overflows during PHP script execution. The following httpd.conf setting will set the stack size to about 8MB (about a typical Linux default):

蜘蛛和机器人
You really should use a file to tell well-behaved spiders not to download dynamically generated pages (edit pages, for instance). This can reduce the load on your webserver, preserve your bandwidth, and prevent duplicate content issues with search engines. However, malicious bots could tie up your webserver and waste your bandwidth by downloading a large volume of pages extremely quickly. Request throttling can help protect against this.
