Could not reliably determine the server's fully qualified domain name

apache2 每次啟動都會出現下面的錯誤訊息：

apache2: Could not reliably determine the server's fully qualified domain name,using xxx.xxx.xxx.xx for ServerName

vi /etc/apache2/apache2.conf ( or vi /etc/httpd/conf/httpd.conf )

在裡面加入了一行：

ServerName www.OOXX.edu.tw

再重新apache2ctl restart
