mysql之用戶受權

受權命令：

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

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

查看用戶受權表：　

　　select user,host,password from mysql.user;

mysql下默認存在mysql數據庫，裏邊的user表存儲着用戶和受權信息。

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

遇到的問題：本地的navicat連接不上我虛擬機的mysql

解決：須要虛擬機的mysql受權給本地的ip：grant all on *.* to user@192.168.64.21 identified by "pass"；
