mysql之用户受权

受权命令：

1.所有权限：grant all on *.* to user@192.168.10.2 identified by "pass"；

2.部分权限：grant select,insert into on *.* to user@192.168.10.2 identified by "pass"

查看用户受权表：　

　　select user,host,password from mysql.user;

mysql下默认存在mysql数据库，里边的user表存储着用户和受权信息。

=======================================

遇到的问题：本地的navicat连接不上我虚拟机的mysql

解决：须要虚拟机的mysql受权给本地的ip：grant all on *.* to user@192.168.64.21 identified by "pass"；
