Question

Can't access Volume from NGINX

Posted April 16, 2021 269 views
NginxDigitalOcean Volumes

I have a Droplet running named XXX.

Inside /etc/nginx/sites-enabled/XXX.xx

I have the following configuration. 

server {

   server_name XXX.xx  www.XXX.xx;

   location / {
     proxy_pass http://localhost:5000;
     proxy_http_version 1.1;
     proxy_set_header Upgrade $http_upgrade;
     proxy_set_header Connection keep-alive;
     proxy_set_header Host $host;
     proxy_cache_bypass $http_upgrade;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /images/ {
        alias /mnt/XXXblob/images/;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/XXX.xx/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/XXX.xx/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


}

Before that I also have runned

sudo chown -R www-data:www-data /mnt/XXXBlob/images/

When I look up /etc/fstab it has the following content.

LABEL=cloudimg-rootfs / ext4 defaults 0 0
LABEL=UEFI /boot/efi vfat defaults 0 0
/dev/disk/by-id/scsi-0DOVolumeXXXBlob /home/portal/XXXBlob ext4 defaults,nofail,discard 0 2

Any help are appreciated!

Hi there,

According to the fstab, your volume should be mounted at /home/portal/XXXBlob. What is the output of the following command:

df -h

What I could suggest here is to mount the volume not on /mnt but inside your document root, so for example if your website files are hosted at /var/www/html/ you could mount the disk to images folder at /var/www/html/images.

Regards,
Bobby

    Thanks for the answer!

    My output from the command are as following:

    My website files are hosted and running from /home/portal/XXXBlob/imagges

    Do you have any suggestions, about what I’m missing?

      Hi there,

      Indeed this looks correctly mounted at /mnt/XXXblob.

      If you run the ls /mnt/XXXblob command do you see the images folder there? And when running ls /mnt/XXXblob/images do you see your files?

      Also when accessing your domain.com/images/some_image.png does it load? If not are there any errors in your web console along with your Nginx error logs?

      Regards,
      Bobby

        Hi again.

        Output for ls /mnt/XXXblob

        images lost+found

        And for running the last command, yes it shows me the files in the directory. But sadly, no - I can’t see it when I visit the browser.

        Can you tell me the command you want me to trigger, to get the Nginx error logs?

          Hi there,

          When trying to visit an image, do you get a 403 error or 404?

          Regards,

            Hi Bobby.

            I’m getting the following error when I visit the path:

            404 Not Found

            nginx/1.18.0 (Ubuntu)

            Hi there,

            I’ve tested this at my end and I managed to get it working by removing the slash at the end of the alias path:

                location /images/ {
        alias /mnt/XXXblob/images;
    }

            Let me know how it goes on your side!
            Regards,
            Bobby

            Hi!

            I just tried to update the sites-available as suggested to the following.

            location /images/ {
        alias /mnt/XXXblob/images;
}

            I afterwards restarted and reloaded (Tried both)

            sudo systemctl reload nginx

            But I’m still getting 404 Not Found.

            Can you provide me with the steps you’re doing, since I must be missing out something?

            Hi there,

            I was able to replicate the problem after adding the proxy pass rules.

            To fix this you could update your configuration to the following:

            upstream backend {
server localhost:5000;
}

server {
    listen 443;
   server_name XXX.xx  www.XXX.xx;


    root /var/www/html;

    location / {
       try_files $uri @backend;
    }

    location @backend {
         proxy_pass http://backend;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection keep-alive;
         proxy_set_header Host $host;
         proxy_cache_bypass $http_upgrade;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header X-Forwarded-Proto $scheme;
     }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/XXX.xx/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/XXX.xx/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

            Then once you have this in place, you would need to mount your volume to your document root defined in the Nginx configuration.

            For example, if you leave the /var/www/html as the document root, then you can mount your images volume to:

            /var/www/html/images

            Let me know how it goes!
            Regards,
            Bobby
