在我们用客户端及其远程连接服务器Mysql数据库的过程中,容易出现下面问题:
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
