translating---geekpi 如何在Linux中检查Apache的模块已经加载
How to Check Which Apache Modules are Enabled/Loaded in Linux
============================================================ ============================================================
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]. 1. mod_ssl – 提供了[HTTPS功能][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. 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 – which offers you to [protect Apache against Brute Force or DDoS attacks][3]. 3. mod_security – 用于[保护Apache免于暴力破解或者DDoS攻击][3]。
4. mod_status – that allows you to [monitor Apache web server load and page statics][4]. 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 help
OR 或者
$ apachectl help $ apachectl help
``` ```
apachectl help apachectl 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：
``` ```
$ apachectl command $ apachectl command
OR 或者
$ apache2ctl command $ apache2ctl command
``` ```
For instance, to start Apache and check its status, run these two commands with root user privileges by employing the [sudo command][6], in case you are a normal user: 比如要启动并检查它的状态，以防你是普通用户，使用[sudo命令][6]来以root用户权限来运行这两个命令：
``` ```
$ sudo apache2ctl start $ sudo apache2ctl start
$ sudo apache2ctl status $ sudo apache2ctl status
``` ```

And when operating in pass-through mode, apache2ctl can take all the Apache arguments in the following syntax: 当在直通模式下，apache2ctl可以用下面的语法带上所有Apache的参数：
``` ```
$ apachectl [apache-argument] $ apachectl [apache-argument]
$ apache2ctl [apache-argument] $ apache2ctl [apache-argument]
``` ```
All the Apache-arguments can be listed as follows: 可以用下面的命令列出所有的Apache参数：
``` ```
$ apache2 help [On Debian based systems] $ apache2 help [在基于Debian的系统中]
$ httpd help [On RHEL based systems] $ httpd help [在RHEL的系统中]
``` ```
#### 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 $ apache2ctl -t -D DUMP_MODULES
OR 或者
$ apache2ctl -M $ apache2ctl -M
``` ```
``` ```
--------------- On RHEL based systems --------------- --------------- 在RHEL的系统中 ---------------
$ apachectl -t -D DUMP_MODULES $ apachectl -t -D DUMP_MODULES
OR 或者
$ httpd -M $ httpd -M
$ apache2ctl -M $ apache2ctl -M
``` ```
