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

設置用戶testuser,能夠在遠程訪問mysql ide
grant all privileges on *.* to testuser@"%" identified by "123456" ;
mysql 新設置用戶或更改密碼後需用flush privileges刷新MySQL的系統權限相關表,不然會出現拒絕訪問,還有一種方法,就是從新啓動mysql服務器,來使新設置生效spa

00x5關於root用戶的訪問設置
設置全部用戶能夠遠程訪問mysql,修改my.cnf配置文件,將bind-address = 127.0.0.1前面加「#」註釋掉,這樣就能夠容許其餘機器遠程訪問本機mysql了;
設置用戶root,能夠在遠程訪問mysql
grant all privileges on *.* to root@"%" identified by "123456" ;
查詢mysql中全部用戶權限
select host,user from user;
關閉root用戶遠程訪問權限
禁止root用戶在遠程機器上訪問mysql
delete from user where user="root" and host="%" ;
修改權限以後,刷新MySQL的系統權限相關表方可生效
flush privileges ;
