查看用户权限:
SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;
权限取决于最上一条记录的值
如果需要收回权限:
REVOKE ALL PRIVILEGES ON *.* FROM ‘root‘@‘ip1‘;
上面这条SQL将置Grant_priv,Super_priv为N,即使接下来执行SQL:
GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY PASSWORD ‘*XXXXX‘ WITH GRANT OPTION;
也不能拯救ip1的无权限,因为上面说了,权限取决于先匹配到的那条记录,最好的方法是:
delete from mysql.user where user=‘root‘ and host=‘ip1‘
