linux远程连接Mysql数据库的问题(ERROR 2003 (HY000)

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): Cant connect to MySQL server on 192.168.0.19 (111)
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
问题代码代码
ERROR 2003 (HY000): Cant connect to MySQL server on 192.168.0.19 (111)
ERROR 2003 (HY000): Cant 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
