登 錄mysql

mysql -u root -p

創建允許本地 IP訪問localhost的Mysql數據庫時出錯

create user ‘lijing‘@‘localhost‘ identified by ‘147258369‘;

ERROR 1396 (HY000): Operation CREATE USER failed for ‘lijing‘@‘localhost‘

出錯原因：

Assume the user is there, so drop the user
After deleting the user, there is need to flush the mysql privileges

以下解決辦法：

創建允許本地 IP訪問localhost的Mysql數據庫：

drop user ‘lijing‘@‘localhost‘;

flush privileges;（刷新系統權限表）

create user ‘lijing‘@‘localhost‘ identified by ‘147258369‘;

創建允許外網IP訪問數據庫lijing，本命令包含上面的命令，是所有的IP都可以訪問該數據庫

create user ‘lijing‘@‘%‘ identified by ‘147258369‘;258369‘;

創建成功後查詢創建的用戶是否成功

select host,user,authentication_string from mysql.user;

創建一個新的數據庫，並使用show databases命令查看數據庫是否創建OK

create database lijingdb DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

MySQL創建新用戶以及ERROR 1396 (HY000)問題解決
