前提

CentOS下Apache默認網站根目錄為/var/www/html,假如我默認存了一個CI項目在html文件夾里，同時服務器的外網IP為ExampleIp,因為使用的是MVC框架，Apache需開啟重定向功能。

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”重啟Apache,那么直接在瀏覽器里輸入http://ExampleIp,就直接映射到/var/www/html/CI文件夾里了

1、配置多域名映射。假設需要映射www.website1.com和www.website1.com這兩個域名，在文檔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為工程目錄.配置完使用“service httpd restart”重啟Apache

2、配置多端口映射。

2.2、首先需要監聽端口，在文檔httpd.conf的Listen 80下添加需要監聽的端口，舉例為8080

Listen 80Listen 8080

2.2、在文檔最后添加端口映射功能

<VirtualHost ExampleIp:8080> DocumentRoot /var/www/html/website3 ServerName ExampleIp:8080</VirtualHost><Directory "/var/www/html/website3"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all</Directory>
