Mysql 远程登陆配置

Posted 2020-06-23

1.修改localhost
更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改成"%"  远程只允许root 登陆
mysql>use mysql;
mysql>update user set host = ‘%‘ where user = ‘root‘;  
mysql>select host, user from user;
mysql>FLUSH PRIVILEGES;

2、指定授权
使用myuser/mypassword从任何主机连接到mysql服务器:
GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘%‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;

使用myuser/mypassword从ip为192.168.31.87的主机连接到mysql服务器:
GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘192.168.31.87‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;

3、泛授权
mysql -h localhost -u root
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ WITH GRANT OPTION;                     //赋予任何主机上以root身份访问数据的权限
mysql>FLUSH PRIVILEGES;
