Mysql配置白名单

1.登录mysql并进入命令行操作

mysql -u root -p

2.如果赋予该ip下该用户所有权限

grant all on *.* to 'username'@'ip' identified by 'password' with grant option;

例如:

grant all on *.* to 'root'@'192.168.1.111' identified by '123@zxcv' with grant option;

如果是赋予部分权限,可以如下:

grant select,create,drop,update,alter on *.* to 'username'@'ip' identified by 'password' with grant option;

3.删除白名单用户的权限

DELETE FROM user WHERE User='username' and Host='ip';

这步慎做,删错了就登不上mysql了

4.刷新权限

FLUSH PRIVILEGES;
