一、配置防火墙，开启80端口、3306端口

CentOS 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。

1、关闭firewall：

systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动

2、安装iptables防火墙

yum install iptables-services #安装
vi /etc/sysconfig/iptables #编辑防火墙配置文件

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
