Nginx - PHP scripts not being called from reverse proxy

Question

I give below an execerpt of of /etc/nginx/sites-available/default file

server {
        listen 443 ssl;
        server_name example.com;

        root /var/www/html;
        index index.php index.html;

location  / {
             try_files $uri $uri/ = 404;
}

location /rproxy/ {
                  proxy_pass https://example.org:8144/;
}     

location ~ \.php$ {
 try_files $uri = 404;
 fastcgi_split_path_info ^(.+\.php)(/.+)$;
 ....
} 

The example.org:8144 server

has the files and

• index.php - returns hello World
• bonjour.php - returns bonjour

Now here is the issue:

If I browse to https://example.com/rproxy it promptly returns hello world - the expected result.

However, if I browse to https://example.com/rproxy/bonjour.php (or even https://example.com/rproxy/index.php) I get a 404 error.

I understand what is happening here. My Nginx configuration is causing the example.com instance of Nginx to attempt to find all *.php files locally (i.e. on example.com) which fails when the file I am seeking is in fact on example.org:8144.

I imagine that there is a relatively simple way to tell Nginx when NOT to attempt to attempt to execute a PHP file - when it is in fact on rproxy. However, my knowledge of Nginx confugration is too limited for me to be able to figure out just how I alter the configuration. I'd be most obliged to anyone who might be tell me how to change the configuration to prevent this from happening.

---

I should clarify something here:

I need to be able to run PHP scripts on Both SERVERS example.com and example.org.

There is a very easy workaround here - I use a different extension, say php5, for php scripts on the proxied server, example.org. However, that is easily liable to lead to unforseen problems.

Answer 1

For nginx regexp locations have bigger priority than prefix locations. But

If the longest matching prefix location has the “^~” modifier then regular expressions are not checked.

So try to replace

location /rproxy/ {

with

location ^~ /rproxy/ {
