编辑apache的配置文件，启用虚拟主机
vi /usr/local/apache/conf/httpd.conf
找到
Include conf/extra/httpd-vhosts.conf
把开头的#注释符号去掉，这样就打开了虚拟主机功能，保存退出
添加虚拟主机
vim /usr/local/apache/conf/extra/httpd-vhosts.conf
里面有两个example，大家其实根据example就可以添加自己的虚拟主机，但是这里为了增加文章篇幅，还是说明一下吧~~
以下是默认的虚拟主机例子
<VirtualHost *:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "/usr/local/apache/docs/dummy-host.example.com"
ServerName dummy-host.example.com
ServerAlias www.dummy-host.example.com
ErrorLog "logs/dummy-host.example.com-error_log"
CustomLog "logs/dummy-host.example.com-access_log" common
</VirtualHost>
<VirtualHost *:80>
ServerAdmin webmaster@dummy-host2.example.com
DocumentRoot "/usr/local/apache/docs/dummy-host2.example.com"
ServerName dummy-host2.example.com
ErrorLog "logs/dummy-host2.example.com-error_log"
CustomLog "logs/dummy-host2.example.com-access_log" common
</VirtualHost>
创建属于自己的虚拟主机，以5abc.net举例
<VirtualHost *:80>
ServerAdmin webmaster@5abc.net
DocumentRoot "/usr/local/apache/htdocs/5abc"
ServerName 5abc.net
ServerAlias www.5abc.net
ErrorLog "logs/5abc.net-error_log"
CustomLog "logs/5abc.net-access_log" common
</VirtualHost>
把编辑好的虚拟主机配置，保存到httpd-vhosts.conf即可，别忘记删除两个example
DocumentRoot就是根目录的路径
创建目录，更改所属用户，用户组
由于目前在/usr/local/apache/htdocs/没有5abc这个目录，那么执行下面命令操作
mkdir /usr/local/apache/htdocs/5abc
chown -R www:www /usr/local/apache/htdocs/
