Magento 1.9.x 安裝sample data 導致admin 清空

Magento 在安裝sample data 後導致無法登入後台

LOCK TABLES `admin_role` WRITE , `admin_user` WRITE;

SET @SALT = "rp";
SET @PASS = CONCAT(MD5(CONCAT( @SALT , "password") ), CONCAT(":", @SALT ));
SELECT @EXTRA := MAX(extra) FROM admin_user WHERE extra IS NOT NULL;

INSERT INTO `admin_user` (firstname,lastname,email,username,password,created,lognum,reload_acl_flag,is_active,extra,rp_token_created_at) 
VALUES ('Firstname','Lastname','email@example.com','myuser',@PASS,NOW(),0,0,1,@EXTRA,NOW());

INSERT INTO `admin_role` (parent_id,tree_level,sort_order,role_type,user_id,role_name) 
VALUES (1,2,0,'U',(SELECT user_id FROM admin_user WHERE username = 'myuser'),'Firstname');

UNLOCK TABLES;

使用以上的sql 語法, 把帳號加回去即可!
