在启动 apache2 时出现
Starting httpd: httpd: apr_sockaddr_info_get() failed for MYHOST
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName.
所以要解决这个问题可以设定 ServerName 或者在 /etc/hosts 中填入自己的主机名称 MYHOST，像这样：
>vi /etc/hosts
127.0.0.1 localhost.localdomain localhost ThinkPad
