httpd: Could not reliably determine the server's fully .......

错误: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName
解决方案：

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。
++++++++++++++++++++++++++++++++++++++++++++ using localhost.localdomain for ServerName 说不能确认服务器完全确认域名 localhost.localdoman 这个问题怎么解决
最佳答案：
vim /usr/local/apache/conf/httpd.conf
vi /etc/httpd/conf/httpd.conf 加入一句 ServerName localhost:80
