mysql添加超级管理员

mysql>create user \'myroot\'@\'localhost\' identified by \'myroot\';
mysql>grant all privileges on *.* to \'myroot\'@\'localhost\';
mysql>flush priviledges;

ok,可以拿myroot在本地登录管理，但是要在远程管理还不行。接下来解决在远程登录管理的问题。

mysql>create user \'myroot\'@\'%\' identified by \'myroot\';
mysql>grant all privileges on *.* to \'myroot\'@\'%\';
mysql>flush priviledges;

还有，mysql.user密码加密的方式是使用PASSWORD进行的。

 

删除用户
mysql>revoke all on *.* from sss@localhost ;
msyql>Delete from user where user = "user_name" and host = "host_name" ;
mysql>flush privileges ;
