centos6下解决"ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.2.200' (113)"

1. 问题描述

远程访问192.168.2.200主机的mysql数据库时, 出现以下错误:

# mysql -host192.168.2.200 -uroot -p
Enter password: 
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.2.200' (113)

2. 解决方法

首先确保mysql开启了远程授权: http://blog.csdn.net/cryhelyxx/article/details/40114695

参考了: http://blog.csdn.net/qustdjx/article/details/26937325

依然无法解决问题, 最后在网上搜索了下, 说是系统的防火墙开启的原因.

参考了: http://www.jb51.net/article/23965.htm   得到了解决方法.

现在关闭防火墙:

# /etc/rc.d/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]

再次远程连接mysql数据库:

# mysql -h192.168.2.200 -uroot -p
Enter password:
