AH00557: httpd: apr_sockaddr_info_get() failed for master
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message
警告原因：配置文件httpd.conf中未设置ServerName
修改如下：vim httpd.conf
#ServerName www.example.com:80
去掉前面的#并修改 后面的域名为自己指定的ip或自定义的域名
如：ServerName localhost:80
