    This is the first time I mention the AUR (and yay) in my entries, so I might as well just write a bit about it.

The one I use (and I think everyone does, too) is yay, which as far as I know is like a wrapper of pacman.

    If you’re going to run it locally (or LAN/VPN) you can start the komga.service and access it via IP at http://<your-server-ip>:<port>(/base_url) as stated at Komga: Accessing the web interface, then you can continue with the mangal section, else continue with the next steps for the reverse proxy and certificate.

    -

    Reverse proxy

    -

    Create the reverse proxy configuration (this is for nginx). In my case I’ll use a subdomain, so this is a new config called komga.conf at the usual sites-available/enabled path:

    -
    server {
-    listen 80;
-    server_name komga.yourdomain.com; # change accordingly to your wanted subdomain and domain name
-
-    location / {
-        proxy_pass http://localhost:8989; # change 8989 to the port you want to use
-
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-
-        proxy_read_timeout 600s;
-        proxy_send_timeout 600s;
-    }
-}
-
    -

    If it’s going to be used as a subdir on another domain then just change the location with /subdir instead of /; be careful with the proxy_pass directive, it has to match what you configured at /etc/komga.conf for the SERVER_SERVLET_CONTEXT_PATH regardless of the /subdir you selected at location.

    -

    SSL certificate

    -

    If using a subdir then the same certificate for the subdomain/domain should work fine and no extra stuff is needed, else if following along me then we can create/extend the certificate by running:

    -
    certbot --nginx
-
    -

    That will automatically detect the new subdomain config and create/extend your existing certificate(s). In my case I manage each certificate’s subdomain:

    -
    certbot --nginx -d domainname.com -d subdomain.domainname.com -d komga.domainname.com
-
    -

    Starting using Komga

    -

    We can now start/enable the komga.service:

    -
    systemctl enable komga.service
-systemctl start komga.service
-
    -

    And access the web interface at https://komga.domainname.com which should show the login page for Komga. The first time it will ask to create an account as shown in Komga: Create user account, this will be an admin account. Fill in the email and password (can be changed later). The email doesn’t have to be an actual email, for now it’s just for management purposes.

    -

    Next thing would be to add any extra account (for read-only/download manga permissions), add/import libraries, etc.. For now I’ll leave it here until we start downloading manga on the next steps.

    -

    Library creation

    -

    Creating a library is as simple as creating a directory somewhere and point to it in Komga. The folowing examples are for my use case, change accordingly. I’ll be using /mnt/d/mangal for my library:

    -
    mkdir /mnt/d/mangal
-
    -

    Where I chose the name mangal as its the name of the downloader/scrapper I’m going to use, it could be anything, this is just how I like to organize stuff.

    -

    For the most part, the permissions don’t matter much (as long as it’s readable by the komga user) unless you want to delete some manga, then komga user also needs write permissions.

    -

    Then just create the library in Komga web interface (the + sign next to Libraries), choose a name “Mangal” and point to the root folder /mnt/d/mangal, then just click Next, Next and Add for the defaults (that’s how I’ve been using it so far). This is well explained at Komga: Libraries.

    -

    The real important part (for me) is the permissions of the /mnt/d/mangal directory, as I want to have write access for komga so I can manage from the web interface itself. It looks like it’s just a matter of giving ownership to the komga user either for owner or for group (or to all for that matter), but since I’m going to use a separate user to download manga then I need to choose carefully.

    -

    Set default directory permissions

    -

    The desired behaviour is: set komga as group ownership, set write access to group and whenever a new directory/file is created, inherit these permission settings. I found out via this stack exchange answer how to do it. So, for me:

    -
    chown manga-dl:komga /mnt/d/mangal # required for group ownership for komga
-chmod g+s /mnt/d/mangal # required for group permission inheritance
-setfacl -d -m g::rwx /mnt/d/mangal # default permissions for group
-setfacl -d -m o::rx /mnt/d/mangal # default permissions for other (as normal, I think this command can be excluded)
-
    -

    Where manga-dl is the user I created to download manga with. Optionally add -R flag to those 4 commands in case it already has subdirectories/files (this might mess file permissions, but it’s not an issue as far as I konw).

    -

    Checking that the permissions are set correctly (getfacl /mnt/d/mangal):

    -
    getfacl: Removing leading '/' from absolute path names
-# file: mnt/d/mangal
-# owner: manga-dl
-# group: komga
-# flags: -s-
-user::rwx
-group::rwx
-other::r-x
-default:user::rwx
-default:group::rwx
-default:other::r-x
-
    -

    You can then check by creating a new subdirectory (in /mnt/d/mangal) and it should have the same group permissions.

This is what I use when downloading manga that already finished publishing, or when I’m just searching and testing out how it downloads the manga (directory name, and manga information).

    Note that some scrapters will contain duplicated chapters, as they have multiple uploaded chapters from the community, usually for different scanlation groups. This happens a lot with MangaDex.

    Now I just check that it is correctly added to Komga by clicking on the 3 dots to the right of the library name and click on “Scan library files” to refresh if the cron timer hasn’t activated this yet.

    -

    Then I check that the metadata is correct (once the manga is fully indexed), such as title, summary, chapter count, language, tags, genre, etc., which honestly it never works fine as mangal creates the series.json with the comicId field with an upper case I and Komga expects it to be a lower case i (comicid) so it falls back to using the info from the first chapter. I’ll probably will fix this on mangal side, and see how it goes.

    So, what I do is manually edit the metadata for the manga, by changing whatever it’s wrong or add what’s missing (I like adding anilist and MyAnimeList links) and then leave it as is.

    Automation

    The straight forward approach for automation is just to bundle a bunch of mangal inline commands in a shell script and schedule it’s execution either via cron or systemd/Timers. But, as always, I overcomplicated/overengineered my approach, which is the following:

      Finally is just a matter of using your prefered way of scheduling, I’ll use systemd/Timers but anything is fine. You could make the downloader script more sophisticated and only running every week on which each manga gets (usually) released but that’s too much work; I’ll just run it once daily probably.

      A feature I want to add and probably will is sending notifications (probably through email) on a summary for manga downloaded or failed to download so I’m on top of the updates. For now this is good enough and it’s been working so far.

      If you’re going to run it locally (or LAN/VPN) you can start the komga.service and access it via IP at http://<your-server-ip>:<port>(/base_url) as stated at Komga: Accessing the web interface, then you can continue with the mangal section, else continue with the next steps for the reverse proxy and certificate.

      -

      Reverse proxy

      -

      Create the reverse proxy configuration (this is for nginx). In my case I’ll use a subdomain, so this is a new config called komga.conf at the usual sites-available/enabled path:

      -
      server {
-    listen 80;
-    server_name komga.yourdomain.com; # change accordingly to your wanted subdomain and domain name
-
-    location / {
-        proxy_pass http://localhost:8989; # change 8989 to the port you want to use
-
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-
-        proxy_read_timeout 600s;
-        proxy_send_timeout 600s;
-    }
-}
-
      -

      If it’s going to be used as a subdir on another domain then just change the location with /subdir instead of /; be careful with the proxy_pass directive, it has to match what you configured at /etc/komga.conf for the SERVER_SERVLET_CONTEXT_PATH regardless of the /subdir you selected at location.

      -

      SSL certificate

      -

      If using a subdir then the same certificate for the subdomain/domain should work fine and no extra stuff is needed, else if following along me then we can create/extend the certificate by running:

      -
      certbot --nginx
-
      -

      That will automatically detect the new subdomain config and create/extend your existing certificate(s). In my case I manage each certificate’s subdomain:

      -
      certbot --nginx -d domainname.com -d subdomain.domainname.com -d komga.domainname.com
-
      -

      Starting using Komga

      -

      We can now start/enable the komga.service:

      -
      systemctl enable komga.service
-systemctl start komga.service
-
      -

      And access the web interface at https://komga.domainname.com which should show the login page for Komga. The first time it will ask to create an account as shown in Komga: Create user account, this will be an admin account. Fill in the email and password (can be changed later). The email doesn’t have to be an actual email, for now it’s just for management purposes.

      -

      Next thing would be to add any extra account (for read-only/download manga permissions), add/import libraries, etc.. For now I’ll leave it here until we start downloading manga on the next steps.

      -

      Library creation

      -

      Creating a library is as simple as creating a directory somewhere and point to it in Komga. The folowing examples are for my use case, change accordingly. I’ll be using /mnt/d/mangal for my library:

      -
      mkdir /mnt/d/mangal
-
      -

      Where I chose the name mangal as its the name of the downloader/scrapper I’m going to use, it could be anything, this is just how I like to organize stuff.

      -

      For the most part, the permissions don’t matter much (as long as it’s readable by the komga user) unless you want to delete some manga, then komga user also needs write permissions.

      -

      Then just create the library in Komga web interface (the + sign next to Libraries), choose a name “Mangal” and point to the root folder /mnt/d/mangal, then just click Next, Next and Add for the defaults (that’s how I’ve been using it so far). This is well explained at Komga: Libraries.

      -

      The real important part (for me) is the permissions of the /mnt/d/mangal directory, as I want to have write access for komga so I can manage from the web interface itself. It looks like it’s just a matter of giving ownership to the komga user either for owner or for group (or to all for that matter), but since I’m going to use a separate user to download manga then I need to choose carefully.

      -

      Set default directory permissions

      -

      The desired behaviour is: set komga as group ownership, set write access to group and whenever a new directory/file is created, inherit these permission settings. I found out via this stack exchange answer how to do it. So, for me:

      -
      chown manga-dl:komga /mnt/d/mangal # required for group ownership for komga
-chmod g+s /mnt/d/mangal # required for group permission inheritance
-setfacl -d -m g::rwx /mnt/d/mangal # default permissions for group
-setfacl -d -m o::rx /mnt/d/mangal # default permissions for other (as normal, I think this command can be excluded)
-
      -

      Where manga-dl is the user I created to download manga with. Optionally add -R flag to those 4 commands in case it already has subdirectories/files (this might mess file permissions, but it’s not an issue as far as I konw).

      -

      Checking that the permissions are set correctly (getfacl /mnt/d/mangal):

      -
      getfacl: Removing leading '/' from absolute path names
-# file: mnt/d/mangal
-# owner: manga-dl
-# group: komga
-# flags: -s-
-user::rwx
-group::rwx
-other::r-x
-default:user::rwx
-default:group::rwx
-default:other::r-x
-
      -

      You can then check by creating a new subdirectory (in /mnt/d/mangal) and it should have the same group permissions.

      Download manga using the TUI by selecting the source/scrapper, search the manga/comic you want and then you can select each chapter to download (use tab to select all). This is what I use when downloading manga that already finished publishing, or when I’m just searching and testing out how it downloads the manga (directory name, and manga information).

      Note that some scrapters will contain duplicated chapters, as they have multiple uploaded chapters from the community, usually for different scanlation groups. This happens a lot with MangaDex.

    Komga library

    Now I just check that it is correctly added to Komga by clicking on the 3 dots to the right of the library name and click on “Scan library files” to refresh if the cron timer hasn’t activated this yet.

    -

    Then I check that the metadata is correct (once the manga is fully indexed), such as title, summary, chapter count, language, tags, genre, etc., which honestly it never works fine as mangal creates the series.json with the comicId field with an upper case I and Komga expects it to be a lower case i (comicid) so it falls back to using the info from the first chapter. I’ll probably will fix this on mangal side, and see how it goes.

    So, what I do is manually edit the metadata for the manga, by changing whatever it’s wrong or add what’s missing (I like adding anilist and MyAnimeList links) and then leave it as is.

    Automation

    The straight forward approach for automation is just to bundle a bunch of mangal inline commands in a shell script and schedule it’s execution either via cron or systemd/Timers. But, as always, I overcomplicated/overengineered my approach, which is the following:

      Finally is just a matter of using your prefered way of scheduling, I’ll use systemd/Timers but anything is fine. You could make the downloader script more sophisticated and only running every week on which each manga gets (usually) released but that’s too much work; I’ll just run it once daily probably.

      A feature I want to add and probably will is sending notifications (probably through email) on a summary for manga downloaded or failed to download so I’m on top of the updates. For now this is good enough and it’s been working so far.
