当我使用命令重新启动我的 Apache 服务器时
sudo /etc/init.d/apache2 restart
我收到以下错误：
Restarting web server apache2
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
... waiting apache2:
Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
服务器是否使用 127.0.1.1 而不是 127.0.0.1？是什么导致了这个错误？
