1.查詢所有賬號資訊

SELECT DISTINCT a.`User`,a.`Host`,a.password_expired,a.password_last_changed,a.password_lifetime,a.* FROM mysql.user a;

2.建立賬號

CREATE USER '賬號名稱'@'host地址' IDENTIFIED BY '密碼';

示例：CREATE USER 'asdfghname'@'192.168.0.111' IDENTIFIED BY '123456';

即：在192.168.0.111上建立賬號是asdfghname，密碼是123456

3.授權

GRANT SELECT ON databasename.* TO '賬號名稱'@'host地址';

示例：GRANT SELECT ON mytestdb.* TO 'asdfghname'@'192.168.0.111';

即：只有查詢許可權

4.新增檢視的許可權
