MySQL 授權指定ip訪問

 MySQL 授權指定ip訪問  我超怕的-https://www.cnblogs.com/iAmSoScArEd/p/13632279.html

 

提前多一次flush privileges一下，是為了防止報錯。

1、指定ip

修改下面命令的:

ip（172.16.1.123）

用戶名（root）

密碼（password）

進行授權

flush privileges;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.1.123' IDENTIFIED BY 'password' WITH GRANT OPTION;
flush privileges;

2、所有ip

修改 下面命令的用戶名（root）、密碼（password）進行授權

flush privileges;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
flush privileges;

 

取消授權

1、指定IP

flush privileges;
REVOKE ALL PRIVILEGES ON *.* FROM 'root'@'172.16.1.123' IDENTIFIED BY 'password' WITH GRANT OPTION;
flush privileges;

 

2、取消所有IP授權

flush privileges;
REVOKE ALL PRIVILEGES ON *.* FROM 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
flush privileges;
