mysql新建用户,授权,删除用户,修改密码1.新建用户。//登录mysql@>mysql -u root -p@>密码//创建用户mysql> insert into mysql.user(host,user,password) values(localhost,phplamp,password(1234));//刷新系统权限表mysql>flush privileges;这样就创建了一个名为：phplamp 密码为：1234 的用户。然后登录一下。mysql>exit;@>mysql -u phplamp -p@>输入密码mysql>登录成功2.为用户授权。//登录mysql（有root权限）。我里我以root身份登录.@>mysql -u root -p@>密码//首先为用户创建一个数据库(phplampdb)mysql>create database phplampdb;//授权phplamp用户拥有phplamp数据库的所有权限。>grant all privileges on phplampdb.* to phplamp@localhost identified by '1234';//刷新系统权限表mysql>flush privileges;mysql>其它操作/*如果想指定部分权限给一用户，可以这样来写:mysql>grant select,update on phplampdb.* to phplamp@localhost identified by '1234';//刷新系统权限表。mysql>flush privileges;*/3.删除用户。@>mysql -u root -p@>密码mysql>delete from user where user=phplamp and host=localhost;mysql>flush privileges;//删除用户的数据库mysql>drop database phplampdb;4.修改指定用户密码。@>mysql -u root -p@>密码mysql>update mysql.user set password=password('新密码') where user=phplamp and host=localhost;mysql>flush privileges;
