linux虚拟机上安装mysql的时候报错

在执行scripts/mysql_install_db --user=mysql的时候出错，
FATAL ERROR: Neither host 'localhost.localdomain' nor 'localhost' could be looked up with
我的etc/hosts文件也有localhost，并且可以ping通，请问该怎么解决呀？

 jpai@jpai-laptop:mysql-5.1.50-linux-i686-glibc23$ scripts/mysql_install_db --basedir=.

(Remember that we are running this command from the  MYSQL_DOWNLOAD_HOME, so the relative path "." works fine for the basedir).
