启动apache遇到错误：httpd: Could not reliably determine the server‘s fully qualified domain name
[root@server httpd-2.2.4]# /usr/local/apache/bin/apachectl start
httpd: Could not reliably determine the server‘s fully qualified domain name, using 127.0.0.1 for ServerName
1）进入apache的安装目录：(视个人安装情况而不同)
[root@server ~]# cd /usr/local/apache/conf
2）编辑httpd.conf文件，搜索"#ServerName"，添加ServerName localhost:80
[root@server conf]# ls
extra httpd.conf magic mime.types original
[root@server conf]# vim httpd.conf
#ServerName www.example.com:80
ServerName localhost:80
3）再重新启动apache 即可。
[root@server ~]# /usr/local/apache/bin/apachectl restart
解决apache启动错误"httpd:Could not reliably determine..."
