显示所有用户,mysql的基本操作
可以实现显示数据库中所有用户。
select user from mysql.user;
select user,host,password from mysql.user;
给表创建用户,授权:
The create user command:
<!---->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';
grant:
<!---->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';
flush:
<!---->mysql> flush privileges;
查看用户信息:
<!---->mysql> select host,user from mysql.user;
