编译玩apache启动的时候报错如下：
[root@goolen httpd-2.2.19]# /usr/local/apache/bin/apachectl start
httpd: apr_sockaddr_info_get() failed for goolen
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

解决：
[root@goolen httpd-2.2.19]# vim /etc/httpd/httpd.conf
添加：
ServerName 192.168.100.50:80

[root@goolen httpd-2.2.19]# service httpd start
[root@goolen httpd-2.2.19]# service httpd status
