MySql数据库用户的创建,删除和查看

时间:2022-11-03 08:28:59

创建用户的命令:

mysql> CREATE USER yy IDENTIFIED BY '123';

yy表示你要建立的用户名,后面的123表示密码,上面建立的用户可以在任何地方登陆。

如果要限制在固定地址登陆,比如localhost 登陆:

mysql> CREATE USER yy@localhost IDENTIFIED BY '123';

授权:

mysql> GRANT ALL PRIVILEGES ON *.* TO user;@localhost
grant select,insert,update,delete on *.* to test1@"%" Identified by "abc";
grant select,insert,update,delete on *.* to test1@"%" Identified by "abc";

格式:grant select on 数据库.* to 用户名@登录主机 identified by “密码”

修改密码:

mysql> grant   all   privileges   on   pureftpd.*   to   koko@localhost   identified   by   'mimi';  

刷新:

mysql> flush privileges;

查看用户信息:

mysql> select host,user from mysql.user;
