centos 6.2 yum 安装mysql初始化警告问题的解决方法，供大家学习参考。
#yum install mysql-server
初始化时出现以下警告：
[root@fengzhige etc]# /etc/rc.d/init.d/mysqld start
Initializing MySQL database: WARNING: The host 'fengzhige' could not be looked up with 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 !
Installing MySQL system tables...
OK
Filling help tables...
OK
按提示，把/etc/hosts添加IP和主机名即可
如[root@37 etc]# cat /etc/hosts
[root@fengzhige etc]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
