MYSQL學習在本地(192.168.1.152)部署好mysql環境,授權遠程客戶機192.168.1.%連接本機的mysql,在iptables防火墻也已開通3306端口.

MYSQL學習如下：

MYSQL學習mysql> select host,user,password from mysql.user;

+--------------+-----------------+---------------------------------------------------------+

| host | user | password |

+--------------+-----------------+----------------------------------------------------------+

| localhost | root | |

| fdm1 | root | |

| 127.0.0.1 | root | |

| localhost | | |

| fdm1 | | |

| 192.168.1.% | db_hqsb | *DFC9DC16B13651A95ECEC3A26E07D244431B55C9 |

| 192.168.1.% | db_ro_hqsb | *2C0B0DD50595BB40879110437BEEF026D019DFB7 |

| 192.168.1.% | db_jkhwuser | *2C0B0DD50595BB40879110437BEEF026D019DFB7 |

| 192.168.1.25| slave | *EE52B8EACB3CCD13624273AD6B5CDA52B9B53EB7 |

| 192.168.1.% | tech_db_user | *6053E57C7B61043DC2C6B4E3291D5F61CCC23F5C |

| 192.168.1.% | game_db_user| *05EA4D71C9A1273ECF3E24E6323F7175AE45C366 |

| localhost | zabbix | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

+---------------+---------------+------------------------------------------------------------+

MYSQL學習問題：

MYSQL學習在客戶機(比如192.168.1.20)上遠程連接上面192.168.1.152機器的mysql,連接失敗!

MYSQL學習

[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

MYSQL學習解決：

MYSQL學習是由于192.168.1.152的mysql里“host為localhost,user和password為空”這條語句導致的,刪除這條即可解決問題!

MYSQL學習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)

MYSQL學習這樣,授權連接的客戶機就能成功連接了!

MYSQL學習

[root@huanqiu ~]# mysql -uxqsj_db_ro_user -h 192.168.1.152 -pmhxzkhl0802xqsjdb
