How to Check Which Apache Modules are Enabled/Loaded in Linux
|
||||
如何在Linux中检查Apache的模块已经加载
|
||||
============================================================
|
||||
|
||||
In this guide, we will briefly talk about the Apache web server front-end and how to list or check which Apache modules have been enabled on your server.
|
||||
本篇中，我们会简要地讨论Apache服务器前端以及如何列出已经启用的Apache模块。
|
||||
|
||||
Apache is built, based on the principle of modularity, this way, it enables web server administrators to add different modules to extend its primary functionalities and [enhance apache performance][5] as well.
|
||||
Apache基于模块构成，因此它可以让web管理员可以添加不同的模块来扩展主要的功能及[增强性能][5]。
|
||||
|
||||
Some of the common Apache modules include:
|
||||
常见的Apache模块有：
|
||||
|
||||
1. mod_ssl – which offers [HTTPS for Apache][1].
|
||||
2. mod_rewrite – which allows for matching url patterns with regular expressions, and perform a transparent redirect using [.htaccess tricks][2], or apply a HTTP status code response.
|
||||
3. mod_security – which offers you to [protect Apache against Brute Force or DDoS attacks][3].
|
||||
4. mod_status – that allows you to [monitor Apache web server load and page statics][4].
|
||||
1. mod_ssl – 提供了[HTTPS功能][1]。
|
||||
2. mod_rewrite – 可以用正则表达式匹配url样式，并且使用[.htaccess技巧][2]来进行透明转发，或者用于HTTP状态码回应。
|
||||
3. mod_security – 用于[保护Apache免于暴力破解或者DDoS攻击][3]。
|
||||
4. mod_status - 用于[监测Apache的负载及页面统计][4]。
|
||||
|
||||
In Linux, the apachectl or apache2ctl command is used to control Apache HTTP server interface, it is a front-end to Apache.
|
||||
在Linux中apachectl或者apache2ctl用于控制Apache服务器，是Apache的前端。

You can display the usage information for apache2ctl as below:

你可以用下面的命令显示apache2ctl的使用信息：

$ apache2ctl help

apache2ctl can function in two possible modes, a Sys V init mode and pass-through mode. In the SysV init mode, apache2ctl takes simple, one-word commands in the form below:

apache2ctl可以工作在两种模式下，SysV init模式和直通模式。在SysV init模式下，apache2ctl用下面的命令形式：

#### Check Enabled Apache Modules

#### 检查启用的Apache模块
|

|

Therefore, in order to check which modules are enabled on your Apache web server, run the applicable command below for your distribution, where `-t -D DUMP_MODULES` is a Apache-argument to show all enabled/loaded modules:
|
||||
因此，为了检测你的Apache服务器启动了哪些模块，在你的发行版中运行适当的命令，`-t -D DUMP_MODULES`是一个Apache参数用于显示所有启用的模块：

||||
```
|
||||
--------------- On Debian based systems ---------------
|
||||
--------------- 在基于Debian的系统中 ---------------
|
||||
$ apache2ctl -t -D DUMP_MODULES
