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：

# /usr/local/mysql/scripts/mysql_install_db \   >      --defaults-file=/etc/my.cnf \   >      --basedir=/usr/local/mysql \   >      --datadir=/var/mysql/data \   >      --user=mysql        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：

?

1 2 3

# 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：

?

1	xxx.xxx.xxx.xxx         r6

 然后重新初始化！
