DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
#DocumentRoot "/usr/local/apache/htdocs" -------把该项禁用掉；
<Directory "/usr/local/apache/htdocs"> # Virtual hosts
Include /etc/httpd/extra/httpd-vhosts.conf ----打开虚拟主机选项；
5）编辑/etc/httpd/extra/httpd-vhosts.conf配置文件：
#<VirtualHost *:80> -------把下面示例虚拟主机选项禁用掉；
# ServerAdmin webmaster@dummy-host.example.com
# DocumentRoot "/usr/local/apache/docs/dummy-host.example.com"
# ServerName dummy-host.example.com
# ServerAlias
# 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>
<VirtualHost *:80> -----------------------增加一下三个虚拟主机，主页面根据自己情况而定；
ServerName
DocumentRoot /web/vhosts/www
<Directory "/web/vhosts/www">
Options Indexes
AllowOverride none
Require all granted
</Directory>
</VirtualHost>
<VirtualHost *:80>
ServerName pma.magedu.com
DocumentRoot /web/vhosts/pma
</VirtualHost>
6）编辑/etc/man.config文件，将man命令永久生效：
# Every automatically generated MANPATH includes these fields
#
MANPATH /usr/man
MANPATH /usr/share/man
MANPATH /usr/local/man
MANPATH /usr/local/share/man
MANPATH /usr/X11R6/man
MANPATH /usr/local/apache/man-----添加man命令路径；
#
# Uncomment if you want to include one of these by default
7）让apache的头文件能被访问到：
#ln -sv /usr/local/apache/include/ /usr/include/
8）开机让httpd服务能进行正常的开启、关闭、重启:
