Ubuntu 16.04 Rails one click images 404 not found.

Question

Images that exist in my repo and display fine in development are 404 not found in production.

I have confirmed the images are present on the production server in root/assets/images/<subdir>/. The images are not accessible in any subpath I have tried typing into the broswer, unlike locally, where I can get a lone image to display in the browser by adding /<subdir>/<imagename> to the url.

I have added the following lines to my /etc/nginx/nginx.conf: server { root /home/rails/<myproj>;

    	location /images/ {
		root /home/rails/<myproj>/app/assets;
	}
	}

No change. I manually precompiled assets on the server with no errors.

My /config/environments/production.rb has the line: config.serve_static_files = ENV[‘RAILS_SERVE_STATIC_FILES’].present?

and the rails environment RAILS_SERVE_STATIC_FILES is set to true.

How can I make my images locatable in my production site?

Hi!

If you are referring to these images from your app, then you need to use image_path in your code, instead of direct link to the image

If you’re server block only consists of:

server {
    root /home/rails/<myproj>;
    
    location /images/ {
        root /home/rails/<myproj>/app/assets;
    }
}

The server block really isn’t complete. You can take a look at the error logs for NGINX to see what is or may be causing the issue by running:

tail -20 /var/log/nginx/error.log

If you’ll paste the output of that command to a code block using the </> icon, we can see if there’s a bit of information there that we can use.

Generally though, when it comes to server blocks, you’d have something that looks more like this:

server {
    listen 80;
    server_name domain.com www.domain.com;
    
    root /home/rails/<myproj>;
    
    location /images {
        root /home/rails/<myproj>/app/assets;
    }
}

That’s very basic and NGINX would only handle /images for you in this case.
