先用root登陸mysql,然後運行下面代碼創建mysql用戶和庫

下面創建的帳號：test123 密碼：123456 庫名：test123

CREATE USER ‘test123‘@‘localhost‘ IDENTIFIED BY ‘123456‘;

GRANT USAGE ON * . * TO ‘test123‘@‘localhost‘ IDENTIFIED BY ‘123456‘ WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

CREATE DATABASE IF NOT EXISTS `test123` ;

GRANT ALL PRIVILEGES ON `test123` . 
 
* TO ‘test123‘@‘localhost‘;

mysql root密碼忘記修改方法參考：http://www.cnblogs.com/kangleweb/p/9364711.html
