我有一个从apt repo运行nagios3的Ubuntu 16.04服务器。
我收到了消息The requested URL/< was not found on this server
etc/apache2/sites-available中的配置文件，软链接到sites-enabled config;
<VirtualHost *:443>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# 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.

为什么会这样？我确定这可能是一个简单的配置错误。我安装了SSL证书，只打开了端口443
