Nignx try files in different directories for different locations - nginx

Question

I have an webapp that uses FastCGI. This app is deployed as different "sites". I have a general nginx configuration for the app, and then, I include upstrams and locations files for each site. Each site needs some .js and .css files. Right now, I have set these via the root of the general configuration file. My requirment now, is that I want to be able to use different .css and .js for different sites. So the lookup of the files, should first start at the site/location level and if not found, then search in the general root.
The general nginx conf file is:
# Change this directory depending on the server
include /etc/nginx/conf.d/app/upstreams/*.conf;
server
{
server_name 24.39.17.76;
root /var/www/app/files/;
listen 443;
ssl on;
ssl_certificate /etc/nginx/conf.d/app/ssl/new/app.pem;
ssl_certificate_key /etc/nginx/conf.d/app/ssl/new/app.com.key;
location ~* ^.+\.(css|js|jpg|jpeg|gif|png|ico|svg|woff|ttf)$ {
access_log off; # this is because otherwise, with jail2ban the user may be banned
# add_header Access-Control-Allow-Origin "*";
expires max;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
add_header Pragma public;
}
# Change this directory depending on the server
include /etc/nginx/conf.d/app/locations/*.conf;
}
Note the lines where I include all locations conf and upstreams files.
Then a particular site, has a upstream file like:
upstream siteX
{
server localhost:9021;
server localhost:9022;
server localhost:9023;
}
And a location file like this one:
location ~ ^/siteX/reps {
access_log /var/log/nginx/app/siteX_reps_access.log;
error_log /var/log/nginx/app/siteX_reps_error info;
if ($arg_service = "true") {
rewrite ^/(.*)$ /service/$1 last;
}
rewrite ^/siteX/(.*)$ /$1 break;
try_files $uri #fastcgiSiteX;
}
location #fastcgiSiteX {
include fastcgi_params;
fastcgi_param REQUEST_URI $uri?$args;
fastcgi_pass fastcgiSiteX;
fastcgi_next_upstream error invalid_header http_500;
}
The html of my webpage that includes the css and js is like this:
<script type="text/javascript" src="/JQDevelopmentLibrary/jQuery.js"></script>
<link rel="stylesheet" type="text/css" href="/TBSDevelopmentLibrary/css/bootstrap.css"/>
But I can easily add a prefix if that helps with any possible solution, like:
<script type="text/javascript" src="/siteX/webfiles/JQDevelopmentLibrary/jQuery.js"></script>
<link rel="stylesheet" type="text/css" href="/siteX/webfiles/TBSDevelopmentLibrary/css/bootstrap.css"/>
SO...the general files are under /var/www/app/files/. However, I would like that for siteX, the files are first searched in another path, say /var/www/siteX/files and only if not found, searched in the general one.
One solution I tried but didn't work is to define this try_files expression:
try_files /siteX/webfiles$uri $uri #fastcgiSiteX;
And then, I put all the folders and files in $document_root/siteX/webfiles, that is, /var/www/app/files/siteX/webfiles/. I thought this solution should work, but it didn't.
Any ideas?
Thanks in advance,

Answer 1

its kind of a hack but it can be done.
location ~ ^/siteX/reps {
access_log /var/log/nginx/app/siteX_reps_access.log;
error_log /var/log/nginx/app/siteX_reps_error info;
if ($arg_service = "true") {
rewrite ^/(.*)$ /service/$1 last;
}
rewrite ^/siteX/(.*)$ /$1 break;
try_files $uri #hack;
}
location #hack {
root /var/www/siteX/files;
try_files $uri $uri/ #fastcgiSiteX;
}
location #fastcgiSiteX {
include fastcgi_params;
fastcgi_param REQUEST_URI $uri?$args;
fastcgi_pass fastcgiSiteX;
fastcgi_next_upstream error invalid_header http_500;
}
