httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

解决办法非常简单：

#vim /web/apache/conf/httpd.conf (在这里/web/apahce是我安装apache的目录，你默认安装的话应该是/usr/local/apache2/icons)

找到#ServerName www.example.com:80   把#去掉，再重启apache即可没事了。

现象：

這個問題應該是沒有在 /etc/httpd/conf/httpd.conf 中設定 ServerName  

最简单的，修改httpd.conf文件，增加:
ServerName www.example.com:80
我的改为:

再次启动就正常了!

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
httpd (pid 7907) already running
修改：去掉注释即可。
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName www.example.com:8080


解决方案：
进入apache的安装目录:
Windows : D:\Program Files\Apache Software Foundation\Apache2.2\conf
linux : /usr/local/apache/conf
用记事本打开httpd.conf
将里面的#ServerName localhost:80注释去掉即可。
再执行httpd
然后可以通过浏览器访问http://localhost：80，如果页面显示“It works！”，即表示apache已安装并启动成功。
