Nginx - Request Tracker in a subdirectory

gistfile1.txt

I had Request Tracker running on https://support.example.com.

Now I want to move it to https://example.com/support/.

In Request Tracker itself, the configuration file contained this:
Set( $WebDomain, 'support.example.com' );  
Set( $WebPath, "");
Set( $WebPort, '443' );

What I want to achieve is this:
Set( $WebDomain, 'example.com' );  
Set( $WebPath, "/support");
Set( $WebPort, '443' );

This part is OK.

My original nginx configuration was (just the relevant parts, leaving out SSL stuff etc)

server {
    listen       [::]:443 ssl spdy;
    listen      0.0.0.0:443 ssl spdy;
    server_name  support.example.com;

    location /REST/1.0/NoAuth {
        # mail submission - only allow from this machine
        allow 127.0.0.1;
        allow ::1;
        deny all;
        root   /usr/share/nginx/html;
        index  index.html index.htm;
        include /etc/nginx/fastcgi_params;
        fastcgi_param  SCRIPT_NAME        "";
        fastcgi_param  PATH_INFO          $uri;
        fastcgi_pass unix:/srv/web/example.com/rt/var/run/fcgi-socket;
    }
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
        include /etc/nginx/fastcgi_params;
        fastcgi_param  SCRIPT_NAME        "";
        fastcgi_param  PATH_INFO          $uri;
        fastcgi_pass unix:/srv/web/example.com/rt/var/run/fcgi-socket;
    }
    location /NoAuth/images {
        root /srv/web/example.com/rt/share/html;
    }
}



The Request Tracker docs on nginx are here:
https://www.bestpractical.com/docs/rt/4.0/web_deployment.html#nginx

There is also a RT module that can control nginx, the configuration it
creates is more advanced and available here:
 https://github.com/bestpractical/rt-extension-nginx/tree/master/etc

The configuration template contains things like:

location <% RT->Config->Get('WebPath') %>/NoAuth/images/ {
        root <% $RT::BasePath %>;
        try_files
            local/html$uri
            <% join ' ', map "$_\$uri", map File::Spec->abs2rel($_, $RT::BasePath), RT->PluginDirs('html') %>
            share/html$uri
            @main
        ;
        expires 1M;
    }

But unfortunately, https://github.com/bestpractical/rt-extension-nginx/blob/master/sbin/rt-generate-nginx-conf:
if ( RT->Config->Get('WebPath') ) {
    die sprintf
        "Only empty WebPath is supported at the moment,"
        ." eg serving RT from http://rt.%s/,"
        ." not http://%s%s/",
        RT->Config->Get('WebDomain'),
        RT->Config->Get('WebDomain'),
        RT->Config->Get('WebPath'),
    ;
}

So it seems I can't use it as-is.




My current config at https://example.com/support (not working):

    location /support {

        include /etc/nginx/fastcgi_params;
        fastcgi_param  SCRIPT_NAME        "";
        fastcgi_param  PATH_INFO          $uri;
        fastcgi_pass unix:/srv/web/example.com/rt/var/run/fcgi-socket;
    }

    location /support/NoAuth/images {
        alias /srv/web/example.com/rt/share/html/NoAuth/images;
    }

(I replaced root with alias in NoAuth/images to get rid of the /support prefix, that part seems to work).

But the /support redirects me to /support/NoAuth/Login.html?next=xxxxxxxxxxxx which creates a redirect loop. Error log:

Have you found a way to solve this? Same problem here.

Found out: You need to set SCRIPT_NAME to "/rt"

fastcgi_param SCRIPT_NAME "/rt";
