Mysql设置用户指定ip地址操作数据库的方法：

语法:

grant priv_type on mysql.user to 'user'@'host' identified by 'password' with grant option;

• priv_type:代表允许操作数据库的权限

• user:代表数据库用户名

• host:代表IP地址

• password:代表设置的密码

刷新user权限表:flush privileges;

三、案例

1、设置所有数据库、所有表、任意ip可以连接数据库,授权给用户名ping并设置密码为123456

grant all on *.* to 'ping'@'%' identified by '123456';
flush privileges;

2、授权表cloud的记录修改权限给连接ip地址是192.168.100.1和用户名是ping并且密码为123456

grant update(name,sex) on cloud to 'ping'@'192.168.100.1' identified by '123456';
flush privileges;

四、查看数据库权限表

mysql> select * from mysql.user where host='localhost'\G;
