mysql添加用户和用户权限

Mysql添加用户
使用可以对mysql数据库用户表有操作权限的用户名登陆mysql
insert into user(Host,User,Password) values('%','name','password');
如果work用户没有登陆权限，则
killall mysqld
share/mysql/mysql.server start
grant all on *.* to work@'%' identified by "password";

MySQL赋予用户权限的命令的简单格式为
grant 权限 on 数据库对象 to 用户
grant 权限 on 数据库对象 to 用户 identified by "密码"

用户名:ad,密码：ad_pass，登陆ip:192.168.0.10
//用户在所有登陆ip的权限
grant all on *.* to ad@‘%’ identified by "ad_pass";

//开放管理MySQL中所有数据库的权限
grant all on *.* to ad@'192.168.0.10' identified by "ad_pass";

//开放管理MySQL中具体数据库(test)的权限
grant all privileges on test to ad@'192.168.0.10' identified by "ad_pass";
或
grant all on test to ad@'192.168.0.10' identified by "ad_pass";

//开放管理MySQL中具体数据库中的表(test.table1)的权限
grant all on test.table1 to ad@'192.168.0.10' identified by "ad_pass"

//开放管理MySQL中具体数据库的表(test.table1)的部分列的权限
grant select(id,se,rank) on test.table1 to ad@'192.168.0.10' identified by "ad_pass";

//开放管理操作指令
grant select,insert,update,delete on test.* to ad@'192.168.0.10' identified by "ad_pass";

//回收权限
revoke all on *.* from ad@localhost;

//查看MySQL用户权限
show grants;
show grants for ad@localhost;
