Apache2模块

---

Apache2是一个模块化的服务器。这意味着只有最基本的功能被纳入核心服务器。其他扩展的功能则是通过模块载入Apache2的。缺省情况下，服务器编译时只包含了一套基本的模块。如果服务器被编译为使用模块的动态装载，那么模块可以单独地被编译，并且可以通过LoadModule指令随时添加模块。否则，Apache2在添加和移除模块时必须被编译。

Ubuntu compiles Apache2 to allow the dynamic loading of modules. Configuration directives may be conditionally included on the presence of a particular module by enclosing them in an <IfModule> block.

You can install additional Apache2 modules and use them with your Web server. For example, run the following command from a terminal prompt to install the MySQL Authentication module:
sudo apt-get install libapache2-mod-auth-mysql

See the /etc/apache2/mods-available directory, for additional modules.

Use the a2enmod utility to enable a module:
sudo a2enmod auth_mysql
sudo service apache2 restart

Similarly, a2dismod will disable a module:
sudo a2dismod auth_mysql
sudo service apache2 restart
