mysql用户权限分配专栏

00x1建立新用户html

  经过root用户登陆以后建立mysql

建立新用户,用户名为testuser,密码为123456 ;sql

grant all privileges on *.* to testuser@localhost identified by "123456" ; 

设置用户testuser,能够在本地访问mysql数据库

grant all privileges on *.* to testuser@localhost identified by "123456" ;

设置用户testuser,能够在远程访问mysql  服务器

grant all privileges on *.* to testuser@"%" identified by "123456"

mysql 新设置用户或更改密码后需用flush privileges刷新MySQL的系统权限相关表,不然会出现拒绝访问,还有一种方法,就是从新启动mysql服务器,来使新设置生效ide

flush privileges ;  

  

00x2设置用户访问数据库权限spa

设置用户testuser,只能访问数据库test_db,其余数据库均不能访问 ;code

grant all privileges on test_db.* to testuser@localhost identified by "123456" ; 

设置用户testuser,能够访问mysql上的全部数据库 ;htm

grant all privileges on *.* to testuser@localhost identified by "123456" ;

设置用户testuser,只能访问数据库test_db的表user_infor,数据库中的其余表均不能访问 ;blog

grant all privileges on test_db.user_infor to testuser@localhost identified by "123456" ; 

  

00x3设置用户操做权限

设置用户testuser,拥有全部的操做权限,也就是管理员 ;

grant all privileges on *.* to testuser@localhost identified by "123456" WITH GRANT OPTION ; 

设置用户testuser,只拥有【查询】操做权限 ;

grant select on *.* to testuser@localhost identified by "123456" WITH GRANT OPTION ;

设置用户testuser,只拥有【查询\插入】操做权限 ;

grant select,insert on *.* to testuser@localhost identified by "123456" ; 

设置用户testuser,只拥有【查询\插入】操做权限 ;

grant select,insert,update,delete on *.* to testuser@localhost identified by "123456" ;

取消用户testuser的【查询\插入】操做权限 ;

REVOKE select,insert ON what FROM testuser

  

00x4设置用户远程访问权限

设置用户testuser,只能在客户端IP为192.168.1.100上才能远程访问mysql ;

grant all privileges on *.* to testuser@“192.168.1.100” identified by "123456" ;

 

00x5关于root用户的访问设置

  设置全部用户能够远程访问mysql,修改my.cnf配置文件,将bind-address = 127.0.0.1前面加“#”注释掉,这样就能够容许其余机器远程访问本机mysql了;

设置用户root,能够在远程访问mysql

grant all privileges on *.* to root@"%" identified by "123456" ;

 

查询mysql中全部用户权限

select host,user from user; 

  关闭root用户远程访问权限

禁止root用户在远程机器上访问mysql

delete from user where user="root" and host="%" ; 

修改权限以后,刷新MySQL的系统权限相关表方可生效

flush privileges ;
