Radarr, the movies organizer

Radarr is part of the Servarr suite: it allows to automatically organize, search and download movies.

You will need Radarr if you plan to organize and enrich your movies collection. Note that Radarr can only manage either movies up to 1080p or 4K. If you want to have both the same movie up to 1080p and in 4K at the same time, you will need to start two instances of Radarr at the same time. More information on this approach can be deducted from the Readarr setup, where you will be running two instances of an *Arr at the same time.

Radarr 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

There are some configuration that must be perform before actually starting the service. You need to briefly start and stop it to let it create the main configuration file, this is required because you need o generate a new API key:

 > /etc/init.d/prowlarr start
 > /etc/init.d/prowlarr stop

Now edit the newly created xml config file /data/daemons/prowlarr/.config/Prowlarr and edit the UrlBase to match the reverse-proxy setup. Only change the following lines in the file, do not edit anything else (unless you know what you are doing):

  <UrlBase>prowlarr</UrlBase>
    <BindAddress>127.0.0.1</BindAddress>
  <AuthenticationMethod>Forms</AuthenticationMethod>
  <AuthenticationRequired>DisabledForLocalAddresses</AuthenticationRequired>

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

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

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

All set! Prowlarr is running.

Head to the indexers 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…
