安装mysql时提示The host 'xxx' could not be looked up with resolveip的解决办法

1、首先用cat查看/etc/hosts文件，会显示以下内容：

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

可见/etc/hosts中无相应的机器名

需添加本机的ip到/etc/hosts中:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.0.109  andylinux

2、使用resolveip确认是否ok

#/usr/local/mysql/bin/resolveip andylinux

IP address of andylinux is 192.168.0.109

说明已经OK了，再次运行mysql安装程序即可。
