mysql初始化出现：FATAL ERROR: Neither host 'DB01' nor 'localhost' could be looked up with

初始化时：

FATAL ERROR: Neither host 'DB01' nor 'localhost' could be looked up with
/application/mysql/bin/resolveip
Please configure the 'hostname' command to return a correct
hostname.

问题解决：

、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
:: 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
:: localhost localhost.localdomain localhost6 localhost6.localdomain6

127.0.0.1  DB01

、使用resolveip确认是否ok

#/usr/local/mysql/bin/resolveip DB01

IP address of DB01 is 127.0.0.1

说明已经OK了，再次运行mysql安装程序即可。
