终端连接mysql是出现error 2003_远程连接MySQL报错ERROR 2003解决办法

问题代码代码

ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.0.19' (111)

ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.0.19' (111) 这个 原因就是Mysql数据库的默认配置文件my.cnf(linux下)中的bind-address默认为127.0.0.1，所以就算你创建了可以 remote访问的用户，你也不能使用mysql -h命令进行访问，若访问就会出现上出问题，因为此时Mysql只接受localhost，所以需要把bind-address屏蔽掉。

my.cnf一般在/etc/mysql下面，如果不在使用locate my.cnf查找，修改前的my.cnf配置文件为：

修改前的my.cnf配置文件代码

#

# Instead of skip-networking the default is now to listen only on

# localhost which is more compatible and is not less secure.

bind-address = 127.0.0.1

#

# Instead of skip-networking the default is now to listen only on

# localhost which is more compatible and is not less secure.

bind-address = 127.0.0.1

我们需要做的就是屏蔽这个bind-address代码，屏蔽后代码为：

屏蔽后my.cnf配置文件代码

#

# Instead of skip-networking the default is now to listen only on

# localhost which is more compatible and is not less secure.

#bind-address = 127.0.0.1

#

# Instead of skip-networking the default is now to listen only on

# localhost which is more compatible and is not less secure.

#bind-address = 127.0.0.1

现在你就可以用mysql -h命令进行你想做的操作了，如登录系统：

登陆数据库代码

mysql -h 192.168.0.19 -u root -p
