配置Varnish 4个多个域的不同端口

Question

I got this to load both the websites, however I am unable to log into both wordpress websites.

backend websiteone {
    .host = "127.0.0.1";
    .port = "7070";
}
backend websitetwo {
    .host = "127.0.0.1";
    .port = "2082";
}
    sub vcl_recv {
    if (req.http.host ~ "^(.*\.)?websiteone\.com$") {
    set req.backend_hint = websiteone;
    return (hash);
}
    if (req.http.host ~ "^(.*\.)?websitetwo\.com$") {
    set req.backend_hint = websitetwo;
    return (hash);
    }
}

Here is what I did to resolve this issue:

 mkdir /etc/varnish/sites-enabled  

 cd /etc/varnish/sites-enabled  

 nano siteone.com.vcl  

sub vcl_recv {
    if (req.http.host == "siteone.com") {
        if (req.url ~ "/(cart|my-account|checkout|addons|/?add-to-cart=)") {
        return (pass);
        }
    }
}

 nano sitetwo.com.vcl  

backend sitetwo {
    .host = "127.0.0.1";
    .port = "2082";
}

sub vcl_recv {
       if (req.http.host == "sitetwo.com") {
           set req.backend_hint = sitetwo;
    }
}

Then I had to edit /etc/varnish/default.vcl

 cd /etc/varnish/  

 nano default.vcl  

The backend is configured for sitetwo as you can see above, but the backend for siteone is configured in default.vcl so I changed

backend default {
    .host = "127.0.0.1";
    .port = "7070";
}

And added these two lines to the bottom of default.vcl

 include "sites-enabled/siteone.com.vcl";
 include "sites-enabled/sitetwo.com.vcl";

Everything seems to be working correctly now! And if I have to add any more sites all I have to do is create sitetree.com.vcl in /sites-enabled folder and paste

backend sitethree {
    .host = "127.0.0.1";
    .port = "port number";
}

sub vcl_recv {
       if (req.http.host == "sitethree.com") {
           set req.backend_hint = sitethree;
    }
}

Note: Siteone is running an ecommerce site so if you are not running a store then you should just be able to use the following in siteone.com.vcl

sub vcl_recv {
       if (req.http.host == "siteone.com") {
           set req.backend_hint = siteone;
    }
}
