解決遠程鏈接數據庫：Host is not allowed to connect to this MySQL server

遠程鏈接數據時，報如下提示：

Host 'web1' is not allowed to connect to this MySQL server

緣由是數據庫服務不容許遠程登陸，沒有受權致使，解決方法以下：

登錄mysql數據庫：

mysql –uroot –p123456

建立並受權一個專用的數據庫wordpress用於存放blog數據：

create database wordpress;

show database like ‘wordpress’;

grant all on worpress.* to worpress@'localhost' identified by '123456';

注：當數據庫和php服務不在同一臺機器上，可執行以下命令受權

grant all on wordpress.* to wordpress@’192.168.0.%’ identified by ‘123456’;

刷新權限，使得建立的用戶生效：

flush privileges;   

查看用戶對應的權限：

select user,host from mysql.user where user='wordpress';  

[root@mysql ~]# mysql -uroot -p123456 Welcome to the MySQL monitor. Commands end with ; or \g.
