mysql中root用户远程连接

如果你连接出错

ERROR 1130: Host '192.168.1.213' is not allowed to connect to this MySQL server

解决方案：

mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;

注意：这里host，user是一个主键。如果报错，请修改为唯一

1.如果允许任意主机连接

GRANT ALL PRIVILEGES ON *.* TO 'youruser'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION;

2.如果限制一个ip连接

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.213' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
