前言
在日常的网站发布中很多情况下都无法做到一个IP对应一个站点，在IP4的情况下IP的资源是相对有限的。然而作为最流行的Apache自然也考虑到这种情况，下面来一起看看详细的介绍吧。
配置方法
首先apache的版本是2.4.7，然后系统是Ubuntu 14.04.1 LTS。（因为好像配置文件和目录有差异）
首先进到apache2目录下,
我们要探讨的主要是sites-available和sites-enabled根据字面意思，前一个是网站可用的，后一个是网站可用的，然后我们还知道了，sites-enabled里面的文件是sites-available里面文件的软链接，所以我们主要改site-available的文件，打开site-available有两个文件，但我们只需要000-default.conf文件，打开cat文件
代码如下：
| <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> |
这就是网址配置文件了，而我们要修改的只有被注释掉的ServerName 域名，DocumentRoot 路径这两个部分，去掉注释剩下。
| <VirtualHost *:80> ServerName #这里是域名地址 ServerAdmin webmaster@localhost DocumentRoot /var/www/ #这里是路径 ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost> |
可以直接添加在下面，重启apache就成了。但是上面的优先级要更高，访问自己的域名会跳转到你设置的路径，直接访问ip还是会到第一个设置的路径，你也可以选择删除。
还有另外一种改法就是新建一个文件，xxx.conf然后内容一样，
