在启动或重启apache时报以下错误，虽然没有影响，但总感觉怪怪的。
httpd: apr_sockaddr_info_get() failed for 103.localdomain
httpd: Could not reliably determine the server‘s fully qualified domain name, using 127.0.0.1 for ServerName
解决方法：
1）进入apache的安装目录：(视个人安装情况而不同)
/etc/httpd/conf/httpd.conf
#ServerName www.example.com:80
ServerName localhost:80
2） vim /usr/local/apache2/conf/httpd.conf ，搜索”#ServerName”，添加ServerName localhost:80
#ServerName www.example.com:80
ServerName localhost:80
3）再重新启动apache 即可。
service httpd restart
/usr/local/apache2/bin/apachectl restart
/usr/local/apache2/bin/apachectl -t
