Note

For this guide you should be familiar with the basic concepts of

License

Pixelfed is open-sourced software licensed under the AGPL license.

Prerequisites

Your URL needs to be setup:

[isabell@stardust ~]$ uberspace web domain list
isabell.uber.space
[isabell@stardust ~]$

You’ll need your MySQL credentials. Get them with my_print_defaults:

[isabell@stardust ~]$ my_print_defaults client
--default-character-set=utf8mb4
--user=isabell
--password=MySuperSecretPassword
[isabell@stardust ~]$

Setup a new MySQL database for Pixelfed:

[isabell@stardust ~]$ mysql -e "CREATE DATABASE ${USER}_pixelfed"
[isabell@stardust ~]$

We’re using PHP in the stable version 8.1:

[isabell@stardust ~]$ uberspace tools version show php
Using 'PHP' version: '8.1'
[isabell@stardust ~]$

Redis

We need Redis for in-memory caching and background task queueing. Please follow the Redis guide to setup redis.

Installation

Note

Pixelfed uses the subdirectory public as web root and you should not install Pixelfed in your DocumentRoot. Instead we install it next to that and then use a symlink to make it accessible.

Clone the source one level above your DocumentRoot using Git:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/
[isabell@stardust isabell]$ git clone https://github.com/pixelfed/pixelfed
Cloning into 'pixelfed'...
[...]
[isabell@stardust isabell]$

cd into your Pixelfed directory and install the necessary dependencies using Composer:

[isabell@stardust isabell]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ composer install

[isabell@stardust pixelfed]$

Remove your empty DocumentRoot and create a new symbolic link to the pixelfed/public directory:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/
[isabell@stardust isabell]$ rm -f html/nocontent.html; rmdir html
[isabell@stardust isabell]$ ln -s /var/www/virtual/$USER/pixelfed/public html
[isabell@stardust isabell]$

Configuration

Warning

Whenever you edit the .env file, you must run php artisan config:cache in the root directory for the changes to take effect.

Copy the example configuration file .env.example to .env and generate a key into the config:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ cp .env.example .env

Open the file .env in your favourite editor and adjust the following blocks accordingly. For minimum privacy we recommend to disable the open registrations:

APP_NAME="Pixelfed"

APP_URL=https://isabell.uber.space
APP_DOMAIN="isabell.uber.space"
ADMIN_DOMAIN="isabell.uber.space"
SESSION_DOMAIN="isabell.uber.space"

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=isabell_pixelfed
DB_USERNAME=isabell
DB_PASSWORD=MySuperSecretPassword

REDIS_SCHEME=unix
REDIS_PATH=/home/isabell/.redis/sock

MAIL_DRIVER=smtp
MAIL_HOST=stardust.uberspace.de
MAIL_PORT=587
MAIL_USERNAME=isabell@uber.space
MAIL_PASSWORD="MySuperSecretPassword"
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS="isabell@uber.space"
MAIL_FROM_NAME="Pixelfed"

OPEN_REGISTRATION=false

Generate the application key

[isabell@stardust pixelfed]$ php artisan key:generate
Application key set successfully.
[isabell@stardust pixelfed]$

Run database migrations:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ php artisan migrate
**************************************
*     Application In Production!     *
**************************************

 Do you really wish to run this command? (yes/no) [no]:
 > yes
[...]
Migrating: 2020_07_25_230100_create_media_blocklists_table
Migrated:  2020_07_25_230100_create_media_blocklists_table (0.09 seconds)
[isabell@stardust pixelfed]$

Note

If you get a database error when running the migrations, ensure you updated the .env with proper database variables and then run php artisan config:cache.

Cache + Optimization Commands

Running the following commands is recommend when running Pixelfed in production:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ php artisan config:cache
Configuration cache cleared!
Configuration cached successfully!
[isabell@stardust pixelfed]$ php artisan route:cache
Route cache cleared!
Routes cached successfully!
[isabell@stardust pixelfed]$ php artisan view:cache
Compiled views cleared!
Blade templates cached successfully!
[isabell@stardust pixelfed]$

Import Places Data

Run the following command to import the Places data:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ php artisan import:cities
Importing city data into database ...

Found 128769 cities to insert ...

 128769/128769 [▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓] 100%

Successfully imported 128769 entries!

[isabell@stardust pixelfed]$

Installing Horizon

Note

Horizon provides a beautiful dashboard and code-driven configuration for our Redis queues. Horizon allows you to easily monitor key metrics of your queue system such as job throughput, runtime, and job failures. It is also needed to execute the queue jobs, for example for thumbnail generation - so this step is not optional.

To install Horizon, run the following commands and recache the routes:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ php artisan horizon:install
Publishing Horizon Service Provider...
Publishing Horizon Assets...
Publishing Horizon Configuration...
Horizon scaffolding installed successfully.
[isabell@stardust pixelfed]$ php artisan route:cache
Route cache cleared!
Routes cached successfully!
[isabell@stardust pixelfed]$

Setup the daemon. Create ~/etc/services.d/horizon.ini with the following content:

[program:horizon]
command=php /var/www/virtual/%(ENV_USER)s/pixelfed/artisan horizon
autostart=yes
autorestart=yes

After creating the configuration, tell supervisord to refresh its configuration and start the service:

[isabell@stardust ~]$ supervisorctl reread
SERVICE: available
[isabell@stardust ~]$ supervisorctl update
SERVICE: added process group
[isabell@stardust ~]$ supervisorctl status
SERVICE                            RUNNING   pid 26020, uptime 0:03:14
[isabell@stardust ~]$

If it’s not in state RUNNING, check your configuration.

Warning

Every time you run php artisan config:cache you have to restart horizon otherwise its shown in the dashboard as inactive.

Configuring Scheduler

Note

The scheduler is used to run periodic commands in the background. The following commands are used in the scheduler:

  • media:optimize - Finds any not optimized media and performs optimization

  • media:gc - Finds any media not used in statuses older than 1 hour and deletes them

  • horizon:snapshot - Generates Horizon analytics snapshot

  • story:gc - Finds expired Stories and deletes them

Add the following cronjob to your crontab to run the scheduler every minute:

* * * * * cd /var/www/virtual/$USER/pixelfed && php artisan schedule:run >> /dev/null 2>&1

Finishing installation

Create your first user as admin with php artisan user:create. This is also a good time to check your email configuration with the email verification:

[isabell@stardust ~]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ php artisan user:create
Creating a new user...

Name:
> isabell

Username:
> isabell

Email:
> isabell@uber.space

Password:
> MySuperSecretPassword

Confirm Password:
> MySuperSecretPassword

Make this user an admin? (yes/no) [no]:
> yes

Manually verify email address? (yes/no) [no]:
> no

Are you sure you want to create this user? (yes/no) [no]:
> yes

Created new user!

Now you can now login by visiting your domain and using the credentials you defined above.

Updates

Note

Check the update feed regularly to stay informed about the newest version.

Run git pull in the pixelfed directory to pull the latest changes from upstream. After that install new dependencies, run the cache commands and migrate the database.

[isabell@stardust ~]$ cd /var/www/virtual/$USER/pixelfed
[isabell@stardust pixelfed]$ git pull origin dev
