Nginx - reverse proxy a Ghost blog with /subfolder

Question

I have a working nginx instance with the rules below. But I'm having difficulties pointing all the requests to domain.com/ghost

I tried modifying the location / {} block to location /ghost/ {} but with no success. I just get a 404 from the ghost app. Any suggestions?

server {
    listen         80;
    server_name domain.com;
    root /home//user/ghost/;
    index index.php;

   # if ($http_host != "domain.com") {
   #      rewrite ^ http://domain.com$request_uri permanent;
   # }

    location / {
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
        proxy_pass http://127.0.0.1:2368;
    }

    location ~* \.(?:ico|css|js|gif|jpe?g|png|ttf|woff)$ {
        access_log off;
        expires 30d;
        add_header Pragma public;
        add_header Cache-Control "public, mustrevalidate, proxy-revalidate";
        proxy_pass http://127.0.0.1:2368;
    }

    location = /robots.txt { access_log off; log_not_found off; }
    location = /favicon.ico { access_log off; log_not_found off; }

    location ~ /\.ht {
            deny all;
    }
}

I'm using a regexp location directive for a similar proxy setup. This is the minified configuration file:

worker_processes  1;
pid               /path/to/file.pid;
worker_priority   15;

events {
    worker_connections 512;
    accept_mutex        on;
}

http {
    server {
        error_log   /path/to/log/error.log error;
        listen      127.0.0.1:9000;
        server_name example.com;

        location ~* (/ghost) {
           expires epoch;
           proxy_no_cache 1;
           proxy_pass http://localhost:1234;
        }

        location / {
            proxy_pass http://localhost:1234;
        }
    }
}

Have solved similar problem with other apps which have no support for subfolders. Both apps are built on one platform, so they both tries to work in /fx dir. I had to place one of them in to subfolder /gpms .

The idea is to redirect requests with referer from subfolder to destinations which links outside of subfolder - i just add subfolder to beginning of such uris. It is not ideal, but it works.

Here is my nginx config:

    server {
    listen 80;
    server_name mydomain.com;

    location / {
    rewrite ^/$ /fx/;
    proxy_pass http://127.0.0.1:56943/;
    proxy_redirect     off;
    proxy_set_header   Host             $host;
    proxy_set_header   X-Real-IP        $remote_addr;
    proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    proxy_read_timeout 300;
    }

     error_log /var/log/nginx/debug.log debug;
     set $if_and_hack "";
     if ( $http_referer ~ '^http://mydomain.com/gpms/.*$' ) {
        set $if_and_hack "refgpms";
        }
     if ( $uri !~ '^/gpms/.*$' ) {
        set $if_and_hack "${if_and_hack}_urinogpms";
     }
     if ( $if_and_hack = "refgpms_urinogpms" ) {
        rewrite  ^/(.*)$ http://$host/gpms/$1;
        }

    location /gpms/ {
    proxy_set_header   X-Real-IP        $remote_addr;
    proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    proxy_cookie_path  /fx /;
    proxy_pass http://127.0.0.1:12788/fx/;
    proxy_redirect     default;
    }
}

External links will be broken, but it is not critical for me and i guess it may be corrected.

$if_and_hack is for overcome nginx limitation on nested conditions.

By the way i have got a cookies issue, because they was set with path, and hit browser bug with not sending cookies for a new path after redirect, so i just remove path from cookies.

Note full link form in rewrite - this form of rewrite immediately redirects browser to new page, you should not change it to just "/gpms/$1".

As alternative, i guess, it may be possible to use nginx module to inspect html content and modify links. I have not tried this. Or consider to use subdomains instead of subfolders.

Good news! As of version 0.4.0 Ghost now supports subdirectory installation. And there are already people who've figured this out and created tutorials.
