Prowlarr, the indexex manager

Prowlarr is part of the Servarr suite: it allows to manage a complex list of indexers for your other tools in a centralized and easy to add/edit/remove way,

You will need Prowlarr to add all your torrent trackers and Usenet indexers in one centralized place for all the others supported tools to use. Also, you can add download clients to Prowlarr and perform direct searches and grabs from within, which is neat too.

Prowlarr is easily installed and managed within Gentoo linux since there is an ebuild for it. All you need to do is unmask it (at the time of writing this it's are masked for AMD64 at least):

 > echo www-apps/prowlarr ~amd64 >> /etc/portage/package.accept_keywords/prowlarr

then install it:

 > emerge -v prowlarr

This step will create a dedicated prowlarr user but you will want to add it to the group media, that you have created before, so that the it will be able to access and manage your media collection:

 > usermod -a -G media prowlarr

Also, you want to move Prowlarr home folder under /data/daemons/prowlarr for consistency and to be protected on the RAID array, so:

 > usermod -m -d /data/daemons/prowlarr prowlarr

Before you proceed, you should make Prowlarr accessible via the reverse-proxy, so that access, configuration and usage will be simplified from the beginning. Add this file to /etc/nginx/folders:

prowlarr.conf

# Prowlarr - indexars
location /prowlarr {
        proxy_pass http://127.0.0.1:9696;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $http_connection;
}
# Allow the API/Indexer External Access via NGINX
location ~ /prowlarr(/[0-9]+)?/api {
        auth_basic off;
        proxy_pass http://127.0.0.1:9696;
}

Add this to your /etc/nginx/folders/main.conf:

include "folders/prowlarr.conf";

and restart nginx:

 > /etc/init.d/nginx restart

Prowlarr will be accessible as http://192.168.0.1/prowlarr.

Add Prowlarr to default runlevel, for autostart on reboot, and start it manually now:

 > rc-update add prowlarr default
 > /etc/init.d/prowlarr start

All set! Prowlarr is running. Now you need to perform some securization and configuration.

Open the Prowlarr web GUI at http://192.168.0.1/prowlarr and go to the settings - general and enable the advance settings from the top bar.

You want to change the following settings:

• bind address: write 127.0.0.1, as you want to hide Prowlarr behind the reverse proxy
• Base URL: write “/prowlarr” as it will be required for reverse-proxy access
• Authentication: use forms
• Authentication request: disable for local addresses (unless you want security also inside your home network, authentication will be provided by the reverse-proxy on the external access)

Save changes and restart the Prowlarr service by going to System and using the link under the profile picture on the top right corner. Be aware that you might need to reload your browser at this point.

Head to the indexr page on the Web GUI and add your trackers / indexers. After you will have added the other services, you will need to go to the settings –> apps and add them one by one. To sync the indexers to the apps, use the sync all indexers button in the indexers page of Prowlarr.

Now, head on to install the other services…
