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： [b]问题代码代码 [/b]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： [b]修改前的my.cnf配置文件代码 [/b]#  # 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 [b]我们需要做的就是屏蔽这个bind-address代码，屏蔽后代码为：[/b] [b]屏蔽后my.cnf配置文件代码 [/b]#  # 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 [b]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：[/b] [b]登陆数据库代码 [/b]mysql -h 192.168.0.19 -u root -p
