最近幾天研發(fā)總是抱怨用Navicat連接MySQL數據庫和打開(kāi)數據表很慢，登錄數據庫分析，查看錯誤日志：


mysql> show variables like 'log_error';
+---------------+--------------------------------+
| Variable_name | Value                          |
+---------------+--------------------------------+
| log_error     | /usr/local/mysql/data/idb3.err |
+---------------+--------------------------------+
1 row in set (0.00 sec)


查看錯誤日志:

[root@idb3 data]# cat /usr/local/mysql/data/idb3.err | grep failure |more

解決方法:
在mysql的配置文件my.cnf中
[mysqld]
節點(diǎn)添加下面兩行

skip-host-cache
skip-name-resolve         

參數解釋如下:
skip-host-cache:禁用主機名緩存
skip-name-resolve:禁用主機名解析        

然后重啟MySQL數據庫即可解決:
# service mysqld restart
