MySQL 常用命令模板

创建数据库

# drop database if exists db_guest;
# create database if not exists db_guest default charset=utf8;

创建用户

# insert into mysql.user(Host,User,Password) values("localhost","guest",password("guest"));

更新用户密码

# SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');

删除用户

# use mysql
# Delete from user where user = "user_name" and host = "host_name" ;

使改变的用户生效

# flush privileges;

对用户授权指定的数据库的表的所有权限

# GRANT ALL PRIVILEGES ON db_guest.* TO 'guest'@'localhost' IDENTIFIED BY 'guest' WITH GRANT OPTION;

对用户授权指定的数据库的表的指定权限

# grant select,update on db_guest.* to 'guest'@'localhost'   identified by 'guest';

撤销权限 Revoke privileges (columns) on what from user; privileges 是要取消的权限， user 是要被取消权限的用户名

# revoke all on phpmyadmin.* from guest@localhost ;

设置 phpadmin 初始化用户 username:guest password:guest databasename:db_guest

drop database if exists db_guest;
drop database if exists phpmyadmin;
create database if not exists db_guest default charset=utf8;
create database if not exists phpmyadmin default charset=utf8;
insert into mysql.user(Host,User,Password) values("localhost","guest",password("guest"));
flush privileges;
GRANT ALL PRIVILEGES ON db_guest.* TO 'guest'@'localhost' IDENTIFIED BY 'guest' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON phpmyadmin.* TO 'guest'@'localhost' IDENTIFIED BY 'guest' WITH GRANT OPTION;
