apache启动报错:httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName解决办法

使用新搭建环境配置yum 了一个apache，配置多个虚拟主机以后，启动报错:httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
当然这个报错并不影响我们使用，只是有报错肯定看着不舒服。下边说下解决办法：

vi /etc/httpd/conf/httpd.conf   配置文件找个位置加入一行代码  ServerName  localhost:80 重启httpd，问题解决。
