WARNING: The host 'r6' could not be looked up with /usr/local/mysql/bin/resolveip.

初始化MySQL数据库提示以下信息：

WARNING: The host 'r6' could not be looked up with /usr/local/mysql/bin/resolveip.

This probably means that your libc libraries are not 100 % compatible

with this binary MySQL version. The MySQL daemon, mysqld, should work

normally with the exception that host name resolving will not work.

This means that you should use IP addresses instead of hostnames

when specifying MySQL privileges !

 解决办法：

查看hosts文件：

# more /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

添加IP和主机名：

xxx.xxx.xxx.xxx         r6

然后重新初始化！
