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

centos6.5rpm安装apache后，执行service httpd start命令报错：Could not reliably determine the server's fully qualified domain name, using xxx for ServerName

解决方法如下：

修改/etc/httpd/conf/httpd.conf文件，添加以下代码：

  ServerName localhost:80

保存后即可正常启动apache服务。
