Installing

1. Verify the following are installed:
   • PHP 7.4+
   • GD Image Processing Library
     • This library is usually installed by default.
     • If you plan on disabling image uploads to use atomboard as a text board only, this library is not required.
2. CD to the directory you wish to install atomboard.
3. Run the command:
   • git clone https://github.com/SthephanShinkufag/atomboard.git ./
4. Copy settings.default.php to settings.php.
5. Configure settings.php
   • When setting ATOM_DBMODE to flatfile, note that all post and ban data are exposed as the database is composed of standard text files. Access to ./inc/flatfile/ should be denied.
   • When setting ATOM_DBMODE to pdo, note that only the MySQL and PostgreSQL databases drivers have been tested. Theoretically it will work with any applicable driver, but this is not guaranteed. If you use an alternative driver, please report back.
   • To require moderation before displaying posts:
     • Ensure your ATOM_DBMODE is set to mysql, mysqli, or pdo.
     • Set ATOM_REQMOD to files to require moderation for posts with files attached.
     • Set ATOM_REQMOD to all to require moderation for all posts.
     • Moderate posts by visiting the management panel.
   • To allow WebM upload:
     • Ensure your web host is running Linux or FreeBSD.
     • Install mediainfo and ffmpegthumbnailer. On Ubuntu, run sudo apt-get install mediainfo ffmpegthumbnailer. On FreeBSD run pkg install mediainfo ffmpegthumbnailer.
   • To remove the play icon from WebM/MP4/MOV thumbnails, delete or rename icons/video_overlay.png or set ATOM_VIDEO_OVERLAY to false.
   • To use ImageMagick instead of GD when creating thumbnails:
     • Install ImageMagick and ensure that the convert command is available.
     • Set ATOM_FILE_THUMBDRIVER to imagemagick.
     • Note: GIF files will have animated thumbnails, which will often have large file sizes.
6. CHMOD write permissions to these directories:
   • ./ (the directory containing atomboard)
   • ./src/
   • ./thumb/
   • ./res/
   • ./inc/flatfile/ (only if you use the flatfile database mode).
7. Navigate your browser to imgboard.php and the following will take place:
   • The database structure will be created.
   • Directories will be verified to be writable.
   • The board index will be written to ATOM_INDEX.

Moderating

If you are not logged in already, log in to the management panel by clicking [Manage]. From this page you are able to delete the post, attached files and/or ban the author.

Updating

1. Obtain the latest release.
   • If you installed via Git, run git pull in atomboard's directory.
   • Otherwise, download and extract a zipped archive.
2. Note which files were modified.
   • If settings.default.php was updated, migrate the changes to settings.php
     • Take care to not change the value of ATOM_TRIPSEED, as it would result in different secure tripcodes.
   • If other files were updated, and you have made changes yourself:
     • Visit GitHub and review the changes made in the update.
     • Ensure the update does not interfere with your changes.

Database structure was last modified on 04th Sep 2019.

Migrating

atomboard includes a database migration tool, which currently only supports migrating from flat file mode to MySQL. While the migration is in progress, visitors will not be able to create or delete posts.

1. Edit settings.php:
   • Ensure ATOM_DBMODE is still set to flatfile.
   • Set ATOM_DBMIGRATE to true.
   • Configure all MySQL-related settings.
2. Open the management panel.
3. Click Migrate Database.
4. Click Start the migration.
5. If the migration was successful:
   • Edit settings.php
     • Set ATOM_DBMODE to mysqli.
     • Set ATOM_DBMIGRATE to false.
   • Click Rebuild All and ensure the board still looks the way it should.

If there was a warning about AUTO_INCREMENT not being updated, you'll need to update it manually via a more privileged MySQL user. Run the following query for one or both of the tables, dependant of the warnings you were issued:

ALTER TABLE (table name) AUTO_INCREMENT = (value to be set)
