varnish 重定向到主页目录

我有一个反向代理，我正在将其设置为办公室仪表板，其背后有几个网络主机。最终我想要：

dashboard.company/nagios to go to nagios.company/

dashboard.company/grafana to go to grafana.company/

我设置了以下VCL：

backend default {
.host = "127.0.0.1";
.port = "80";
}  
backend nagios {
  .host = "10.8.1.14";
  .port = "80";
}
backend grafana {
  .host = "10.8.3.88";
  .port = "80";
}

sub vcl_recv {
if (req.url ~ "^/grafana") {
    unset req.http.proxy;
    set req.backend = grafana;
    return (pass);
} elsif (req.url ~ "^/nagios") {
    unset req.http.proxy;
    set req.backend = nagios;
    return (pass);
} else {
    set req.backend = default;
}
}

但当我尝试去http://dashboard.company:6081/grafana，它将“grafana”URL 位传递给后端。我希望请求转到源主机 webdir 而不是源主机/grafana。我该怎么做？

您需要删除第一级 URL，并使用set req.backend_hint而不是来将请求传递到相应的后端set req.backend，如下所示：

backend default {
    .host = "127.0.0.1";
    .port = "80";
}  
backend nagios {
    .host = "10.8.1.14";
    .port = "80";
}
backend grafana {
    .host = "10.8.3.88";
    .port = "80";
}

sub vcl_recv {
    if (req.url ~ "^/grafana") {
        unset req.http.proxy;
        set req.backend_hint = grafana;
        set req.url = regsub(req.url, "^/grafana", "/");
        return (pass);
    } elsif (req.url ~ "^/nagios") {
        unset req.http.proxy;
        set req.backend_hint = nagios;
        set req.url = regsub(req.url, "^/nagios", "/");
        return (pass);
    } else {
        set req.backend = default;
    }
}

本质上，这意味着 下的所有 URL 都将从后端的根（）/nagios传递，并且 下的所有 URL都将从后端的根（）传递。/nagios/grafana/grafana
