尽管仔细遵循在线指导，虚拟主机仍无法正常工作

Question

可能没有什么比对这个问题的问题更能引起人们的蔑视了，但我真的很茫然：

我有2个IP地址，主要的77.68.123.127指向默认的VirtualHost，000-default == www.oneasl.com，第二个77.68.122.124指向davical == cal。 oneasl.com。追加2个conf文件，然后输出'root@asl1:/etc/php/7.2/apache2# apache2ctl -S'

php 在77.68.123.127/davical工作

77.68.123.127 在浏览器中将我带到 apache2 欢迎页面 77.68.123.127/davical 带我进入 davical 登录 77.68.123.127:8080 带我去tomcat8

到目前为止一切顺利

然而 77.68.122.124 应该 == 77.68.123.127/davical == cal.oneasl.com，但它没有加载任何东西...？

如果我忽略了一些明显的事情，非常感谢和抱歉。也很抱歉无偿使用代码标记，但没有它我无法发布！

<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that

# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.

似乎没有在服务器上正确配置辅助 IP。 同时能够在主服务器 ip www.oneasl.com 上远程登录

telnet oneasl.com 80
Trying 77.68.123.127...
Connected to oneasl.com.

无法在辅助服务器 ip cal.oneasl.com 上远程登录

 telnet cal.oneasl.com  80
