MySql 新增使用者與設定權限
每次要在 MySQL 新稱使用者總是用一次查一次，我來記錄一下好了。要新增使用者與賦予權限的方式如下：
先使用 root 進入 MySQL
mysql -uroot -p
接下來我們新增一個使用者 killme, 密碼設定為 killpwd, 並且給予資料庫的所有權限

use mysql;
INSERT INTO user(host,user,password) VALUES('%','killme',password('killpwd'));
GRANT ALL ON *.* TO 'killme'@localhost IDENTIFIED BY 'killpwd' WITH GRANT OPTION;
FLUSH PRIVILEGES;
|
如果要給予使用者特定資料庫的操作權限可以這麼做：
1 |
GRANT SELECT,INSERT,UPDATE,DELETE,CREATE ON dbname.* TO 'killme'@localhost IDENTIFIED BY 'killpwd';
|
執行過程如下:
