  • 解决远程连接数据库:Host is not allowed to connect to this MySQL server

    远程连接数据时,报以下提示:

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

    原因是数据库服务不允许远程登录,没有授权导致,解决方法如下:

    登陆mysql数据库:

    mysql –uroot –p123456

    创建并授权一个专用的数据库wordpress用于存放blog数据:

    create database wordpress;

    show database like ‘wordpress’;

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

    注:当数据库和php服务不在同一台机器上,可执行如下命令授权

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

    刷新权限,使得创建的用户生效:

    flush privileges;   

    查看用户对应的权限:

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

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

    mysql> grant all on wordpress.* to wordpress@'192.168.0.%' identified by '123456';
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> flush privileges;
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> select user,host from mysql.user where user='wordpress';
    +-----------+-------------+
    | user      | host        |
    +-----------+-------------+
    | wordpress | 192.168.0.% |
    +-----------+-------------+
    1 row in set (0.00 sec)
