Mysql 添加用户并授所有权

Posted 2022-06-03 dyh004

创建用户并授权
GRANT ALL PRIVILEGES ON *.* TO ‘caoxiaobo‘@‘%‘ IDENTIFIED BY ‘Caoxiaobo0917!‘ WITH GRANT OPTION;

给root授予所有权，包括远程访问

GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘1‘ WITH GRANT OPTION;

第一次安装，查看root密码

grep ‘temporary password‘ /var/log/mysqld.log

 

去掉密码策略，修改my.cfg，在[mysqld]添加

validate_password = off

 

修改密码

 

修改密码[注意：后面的分号一定要跟上]

mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘MyNewPass4!‘;

或者：

mysql> set password for ‘root‘@‘localhost‘=password(‘MyNewPass4!‘);

 

 

使修改生效

FLUSH PRIVILEGES;
