[root@localhost bin]# ./apachectl start
httpd: Could not reliably determine theserver's fully qualified domain name, using localhost.localdomain forServerName
[root@localhost bin]# ./apachectl stop
httpd: Could not reliably determine theserver's fully qualified domain name, using localhost.localdomain forServerName

#ServerName localhost:80 //将注释("#")去掉,就不会说找不到确定的服务器域名了。
