在本地(192.168.1.152)部署好mysql环境,授权远程客户机192.168.1.%连接本机的mysql,在iptables防火墙也已开通3306端口。
如下:
mysql> select host,user,password from mysql.user;
+--------------+-----------------+---------------------------------------------------------+
| host              | user                 | password                                                                  |
+--------------+-----------------+----------------------------------------------------------+
| localhost       | root                 |                                                                                  |
| fdm1            | root                 |                                                                                  |

| localhost       |                        |                                                                                  |

问题:
在客户机(比如192.168.1.20)上远程连接上面192.168.1.152机器的mysql,连接失败!
[root@huanqiu ~]# mysql -udb_ro_hqsb -h 192.168.1.152 -pmhxzkhl0802xqsjdb
ERROR 1130 (HY000): Host ‘192.168.1.20‘ is not allowed to connect to this MySQL server


解决:
是由于192.168.1.152的mysql里“host为localhost,user和password为空”这条语句导致的,删除这条即可解决问题!

mysql> delete from mysql.user where host="localhost" and user="";
Query OK, 1 row affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


这样,授权连接的客户机就能成功连接了!
[root@huanqiu ~]# mysql -uxqsj_db_ro_user -h 192.168.1.152 -pmhxzkhl0802xqsjdb
