apache启动报No address associated with hostname: mod_unique_id: unable to find IPv4

apache不能启动，查error_log, 有以下错误信息：

[Fri Jul 08 10:07:33 2011] [alert] (EAI 5)No address associated with hostname: mod_unique_id: unable to find IPv4 address of "LinuxServer3"

解决方法：

    注释掉LoadModule unique_id_module modules/mod_unique_id.so

  或者：

        echo 127.0.0.1 LinuxServer3 >> /etc/hosts
