I am using the following config on my http block on nginx.conf:

fastcgi_cache_path /var/www/nginx_cache levels=1:2 keys_zone=NGINXCACHE:500m inactive=60m;
fastcgi_cache_key "$scheme$request_method$host$request_uri";
fastcgi_cache_use_stale error timeout invalid_header http_500;

This works for all websites hosted on this nginx server. I would like to know if it is possible to have each website cache files stored under a specific folder, something like:

  • /tmpfs/fastcgi_cache/website1
  • /tmpfs/fastcgi_cache/website2

When I daclare multiple fastcgi_cache_path's nginx start gives me a error, even with different zones.

Best regards.

You can define multiple cache paths in the nginx http context:

fastcgi_cache_path /var/run/nginx/cache/site1 levels=1:2 keys_zone=SITE1:100m inactive=1w;
fastcgi_cache_path /var/run/nginx/cache/site2 levels= keys_zone=SITE2:123m inactive=60m;
# other fastcgi_cache_* settings here or in your servers/locations

server {
    server_name site1.com;
    # blablabla

    location ~ \.bla$ {
        # blablabla
        fastcgi_cache SITE1;
    }
}

server {
    server_name site2.com;
    # blablabla

    location ~ \.bla$ {
        # blablabla
        fastcgi_cache SITE2;
    }
}

My nginx:

nginx -V
nginx version: nginx/1.1.19
TLS SNI support enabled
configure arguments:
--prefix=/etc/nginx
--conf-path=/etc/nginx/nginx.conf
--error-log-path=/var/log/nginx/error.log
--http-client-body-temp-path=/var/lib/nginx/body
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi

--http-proxy-temp-path=/var/lib/nginx/proxy
--http-scgi-temp-path=/var/lib/nginx/scgi
--http-uwsgi-temp-path=/var/lib/nginx/uwsgi
--lock-path=/var/lock/nginx.lock

For anybody that followed https://www.digitalocean.com/community/tutorials/how-to-setup-fastcgi-caching-with-nginx-on-your-vps and is having issues setting up caching for multiple sites and is getting the error nginx: [emerg] "fastcgi_cache_key" directive is duplicate.

My solution was to place the fastcgi_cache_key "$scheme$request_method$host$request_uri"; within /etc/nginx/nginx.conf. As opposed to putting it in /etc/nginx/sites-enabled/vhost config which the above tutorial alludes to.

Hope this helps anybody else having a similar issue to me.
