1.修改 /etc/httpd/conf/httpd.conf
添加一个Listen，如：
Listen 80 Listen 8001 Listen 8002
2.添加一个VirtualHost
#vim /etc/httpd/conf.d/vhost.conf
NameVirtualHost *:8001
<VirtualHost *:8001>
DocumentRoot /var/www/html/public_html
ServerName localhost
ServerAdmin gr00kiter@gmail.com
#ErrorLog "| /usr/sbin/rotatelogs /var/www/html/log/public_html_error_%Y_%m_%d.log 86400 480"
#CustomLog "| /usr/sbin/rotatelogs /var/www/html/log/public_html_access_%Y_%m_%d.log 86400 480" common
ErrorLog "/var/www/html/log/error.log"
CustomLog "/var/www/html/log/access.log" common
</VirtualHost>
NameVirtualHost *:8002
<VirtualHost *:8002>
DocumentRoot /var/www/html/phpmyadmin
ServerName localhost
ServerAdmin gr00kiter@gmail.com
#ErrorLog "| /usr/sbin/rotatelogs /var/www/html/log/public_html_error_%Y_%m_%d.log 86400 480"
#CustomLog "| /usr/sbin/rotatelogs /var/www/html/log/public_html_access_%Y_%m_%d.log 86400 480" common
ErrorLog "/var/www/html/log/error.log"
CustomLog "/var/www/html/log/access.log" common
</VirtualHost>
3.为新端口添加防火墙规则
iptables -I INPUT -p tcp --dport 8001 -j ACCEPT /etc/rc.d/init.d/iptables save
4.禁用selinux(如果不禁用，会无法重新启动apache)
方法1.关闭selinux
vim /etc/selinux/config
首先将SELINUX=enforcing添加注释
#SELINUX=enforcing
然后在文件末尾添加如下代码
SELINUX=disabled
方法2.修改selinux规则
首先查看现在支持http的端口有哪些
semanage port -l | grep http
然后为http服务新的端口号
semanage port -a -t http_port_t -p tcp 8001
查看添加的结果
semanage port -l | grep http
5.重启httpd服务
service httpd restart
