If it can help you refine installation instructions, I did

bash> git clone ...
bash> composer install --no-dev
bash> chmod a+x artisan
mysql> CREATE NEW DATABASE pixelfed CHARACTER SET utf8mb4;
mysql> GRANT ALL ON pixelfed.* TO 'pixelfed'@'localhost' IDENTIFIED BY '...';
bash> nano config/database.php
bash> ./artisan migrate:fresh

and I got

SQLSTATE[HY000]: General error: 1709 Index column size too large. The maximum column size is 767 bytes. (SQL: alter table `users` add unique `users_username_unique`(`username`))

Additional information:

bash> mysqld --version
mysqld  Ver 10.1.26-MariaDB-0+deb9u1 for debian-linux-gnu on x86_64 (Debian 9.1)

my.cnf:

innodb_large_prefix   = 1
innodb_file_format    = BARRACUDA
innodb_file_per_table = 1

@MrPetovan you might want to file this as a separate issue

There are quite a number of open issues already, I didn't want to pile on, but sure.

Crude installation instructions for Debian 9/Apache/MariaDB:

1. shell> apt install jpegoptim
2. shell> git clone https://github.com/dansup/pixelfed /path/to/pixelfed
3. shell> cd /path/to/pixelfed
4. shell> composer install --no-dev (Composer install)
5. mysql> CREATE NEW DATABASE pixelfed CHARACTER SET utf8mb4;
mysql> GRANT ALL ON pixelfed.* TO 'pixelfed'@'localhost' IDENTIFIED BY '...';
6. shell> cp .env.example .env
7. shell> php artisan key:generate
8. shell> php artisan storage:link (#141)
9. shell> nano .env (edit database settings, hostname, etc...)
10. Enable this hack: Support MariaDB #132 (comment)
11. shell> php artisan migrate:fresh
12. Set the DocumentRoot in your Apache vhost to /path/to/pixelfed/public
13. Voila! 🎉

Is there any cronjob to install I should know about?
