[MySQL]IP address '192.168.31.110' could not be resolved: Temporary failure in name resolution

查看MySQL数据库日志，发现大量Warning：

2014-07-29 16:53:34 18928 [Note] /home/mysql/mysql/bin/mysqld: ready for connections.
Version: '5.6.12'  socket: '/home/mysql/mysql/mysql.sock'  port: 23306  MySQL Community Server (GPL)

192.168.31.110是我本机的IP地址，也就是说服务器上的MySQL无法将192.168.31.110这个IP地址解析为主机名

在服务器的/etc/hosts文件中添加上本机的地址信息（需root权限）：

192.168.31.110 ThinkPad

然后重启MySQL服务，使用本地客户端连接至MySQL后再次观察日志文件，这次没有Warning信息了

还有一种去掉Warning信息的方式是在启动时附带参数，忽略主机名解析：

[mysql@fedora1 ~]$ mysql.server start --skip-name-resolve
