我们大多情况是一台服务器一个IP，这样配置起来很简单，但是如何想多域名多端口映射的话就没那么简单了，下面这篇文章主要介绍了CentOS系统下Apache配置多域名或多端口映射的方法,需要的朋友可以参考学习，下面来一起看看吧。

前提

CentOS下Apache默认网站根目录为/var/www/html,假如我默认存了一个CI项目在html文件夹里，同时服务器的外网IP为ExampleIp,因为使用的是MVC框架，Apache需开启重定向功能。

方法如下

/etc/httpd/conf/httpd.conf文件配置如下：

DocumentRoot "/var/www/html/CI"

<Directory /> Options FollowSymLinks AllowOverride All</Directory>

<Directory "/var/www/html/CI">## Possible values for the Options directive are "None", "All",# or any combination of:# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews## Note that "MultiViews" must be named *explicitly* --- "Options All"# doesn't give it to you.## The Options directive is both complicated and important. Please see# http://httpd.apache.org/docs/2.2/mod/core.html#options# for more information.# Options Indexes FollowSymLinks## AllowOverride controls what directives may be placed in .htaccess files.# It can be "All", "None", or any combination of the keywords:# Options FileInfo AuthConfig Limit# AllowOverride All## Controls who can get stuff from this server.# Order allow,deny Allow from all</Directory>

配置完使用“service httpd restart”重启Apache,那么直接在浏览器里输入http://ExampleIp,就直接映射到/var/www/html/CI文件夹里了

1、配置多域名映射。假设需要映射www.website1.com和www.website1.com这两个域名，在文档httpd.conf最后添加

NameVirtualHost *:80<VirtualHost *:80>DocumentRoot /var/www/html/website1ServerName http://www.website1.com </Virtualhost><Directory "/var/www/html/website1"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all</Directory><VirtualHost *:80>DocumentRoot /var/www/html/website1ServerName http://website1.com </Virtualhost><Directory "/var/www/html/website1">Options Indexes FollowSymLinksAllowOverride AllOrder allow,denyAllow from all</Directory><VirtualHost *:80>DocumentRoot /var/www/html/website2ServerName http://www.website2.com </Virtualhost><Directory "/var/www/html/website2"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all</Directory><VirtualHost *:80>DocumentRoot /var/www/html/website2ServerName http://website2.com </Virtualhost><Directory "/var/www/html/website2">Options Indexes FollowSymLinksAllowOverride AllOrder allow,denyAllow from all</Directory>

website1和website2为工程目录.配置完使用“service httpd restart”重启Apache

2、配置多端口映射。

2.2、首先需要监听端口，在文档httpd.conf的Listen 80下添加需要监听的端口，举例为8080
