ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.33.10' (111) 解决方法

Posted 2020-10-15 Basu

谷歌了一下之后，原来是在mysql的my.cnf中有下面一段代码：

# 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  #这里默认监听本地localhost

 

如果要让mysql监听到其他的地址，可以将bind-address = 127.0.0.1注释掉。 

或者将bind-address = 0.0.0.0监听所有的地址

 

 

如果想让192.168.10.83能够连接到本地的这个数据库，要让数据库给其分配权限,登录mysql，执行:(username 和 password是登录mysql的用户名和密码)

GRANT ALL PRIVILEGES ON *.* TO ‘username‘@‘192.168.10.83‘ IDENTIFIED BY ‘password‘ WITH GRANT OPTION;

如果要想所有的外部ip地址都能够访问使用mysql，可以执行下面：

GRANT ALL PRIVILEGES ON *.* TO ‘username‘@‘%‘ IDENTIFIED BY ‘password‘ WITH GRANT OPTION;

 

之后执行刷新数据库：

flush privileges;
