前言
在日常的網站發布中很多情況下都無法做到一個IP對應一個站點，在IP4的情況下IP的資源是相對有限的。然而作為最流行的Apache自然也考慮到這種情況，下面來一起看看詳細的介紹吧。
配置方法
首先apache的版本是2.4.7，然后系統是Ubuntu 14.04.1 LTS。（因為好像配置文件和目錄有差異）
首先進到apache2目錄下,
我們要探討的主要是sites-available和sites-enabled根據字面意思，前一個是網站可用的，后一個是網站可用的，然后我們還知道了，sites-enabled里面的文件是sites-available里面文件的軟鏈接，所以我們主要改site-available的文件，打開site-available有兩個文件，但我們只需要000-default.conf文件，打開cat文件
代碼如下：
| <VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must seothert it for any further virtual host explicitly. #ServerName www.example.com ServerAdmin webmaster@localhost DocumentRoot /var/www/ # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf</VirtualHost> |
這就是網址配置文件了，而我們要修改的只有被注釋掉的ServerName 域名，DocumentRoot 路徑這兩個部分，去掉注釋剩下。
| <VirtualHost *:80> ServerName #這里是域名地址 ServerAdmin webmaster@localhost DocumentRoot /var/www/ #這里是路徑 ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost> |
可以直接添加在下面，重啟apache就成了。但是上面的優先級要更高，訪問自己的域名會跳轉到你設置的路徑，直接訪問ip還是會到第一個設置的路徑，你也可以選擇刪除。
還有另外一種改法就是新建一個文件，xxx.conf然后內容一樣，
