最近几天研发总是抱怨用Navicat连接MySQL数据库和打开数据表很慢,登录数据库分析,查看错误日志:


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


查看错误日志:

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

解决方法:
在mysql的配置文件my.cnf中
[mysqld]
节点添加下面两行

skip-host-cache
skip-name-resolve         

参数解释如下:
skip-host-cache:禁用主机名缓存
skip-name-resolve:禁用主机名解析        

然后重启MySQL数据库即可解决:
# service mysqld restart
