apache部署多域名，同个ip部署多个网站

Posted 2020-10-14

写个总结笔记，让以后的自己知道怎么部署。
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 [email protected]
        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 [email protected]
        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，

<VirtualHost *:80>
        ServerName #这里是域名地址
        ServerAdmin [email protected]
        DocumentRoot /var/www/          #这里是路径
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

在创建软链接 ln -s ../sites-avaiable/xxx.conf ../sites-enable/xxx.conf
这样子也可以实现，但是优先级还是000-default.conf高。
好了，就是这么简单。
