Alternative Server Components

This file provides some configurations for systems that will not be using the "stock" server components.

Supervisord

An alternative to using systemd for controlling your mastodon processes is Supervisord. The following file can be placed in /etc/supervisor/conf.d/mastodon.conf.

[group:mastodon]
programs=web,sidekiq,streaming

[program:web]
command=/home/mastodon/live/ruby_wrapper bundle exec puma -C config/puma.rb
user=mastodon
directory=/home/mastodon/live
stdout_logfile=/home/mastodon/live/log/puma.log
stdout_logfile_maxbytes=1MB
stdout_logfile_backups=10
redirect_stderr=true
environment=PORT=3000
stopasgroup=true

[program:sidekiq]
command=/home/mastodon/live/ruby_wrapper bundle exec sidekiq -c 5 -q default -q mailers -q pull -q push
user=mastodon
directory=/home/mastodon/live
stdout_logfile=/home/mastodon/live/log/sidekiq.log
stdout_logfile_maxbytes=1MB
stdout_logfile_backups=10
redirect_stderr=true
environment=DB_POOL=5
stopasgroup=true

[program:streaming]
command=/home/mastodon/live/ruby_wrapper /usr/bin/npm run start
user=mastodon
directory=/home/mastodon/live
stdout_logfile=/home/mastodon/live/log/streaming.log
stdout_logfile_maxbytes=1MB
stdout_logfile_backups=10
redirect_stderr=true
environment=PORT=4000
stopasgroup=true

This configuration makes use of a wrapper script to ensure the correct environment.

#!/usr/bin/env bash

cd /home/mastodon/live
export RBENV_ROOT=/home/mastodon/.rbenv
export PATH=/home/mastodon/.rbenv/bin:/home/mastodon/.rbenv/shims:$PATH
export $(cat ".env.production" | xargs)

$@

Running with init scripts

Example init script for the web workers, to be placed in /etc/init.d/mastodon-web:

#!/sbin/openrc-run

name="Mastodon Web Service"
root="/home/mastodon/live"
pidfile="${root}/web.pid"

depend() {
    use net
}

start() {
    ebegin "Starting Mastodon web workers"

    cd $root

    start-stop-daemon --start \
        --chdir "${root}" \
        --user="mastodon" \
        --pidfile="${pidfile}" \
        --exec /usr/bin/env -- RAILS_ENV=production PORT=3000 bundle exec puma -C config/puma.rb -d --pidfile ${pidfile}

    eend $?
}

stop() {
    ebegin "Stopping Mastodon web workers"
    start-stop-daemon --stop \
        --pidfile=${pidfile} \
    eend $?
}

Example init script for the background workers, to be placed in /etc/init.d/mastodon-sidekiq:


#!/sbin/openrc-run

name="Mastodon background workers Service"
root="/home/mastodon/live"
pidfile="${root}/worker.pid"
logfile="${root}/sidekiq.conf"

depend() {
    use net
    need redis
}

start() {
    ebegin "Starting Mastodon background workers"

    cd $root

    start-stop-daemon --start \
        --chdir "${root}" \
        --user="mastodon" \
        --pidfile="${pidfile}" \
        --exec /usr/bin/env -- RAILS_ENV=production DB_POOL=5 bundle exec sidekiq -d -P ${pidfile} -L ${logfile} -c 5 -q default -q mailers -q pull -q push
    eend $?
}

stop() {
    ebegin "Stopping Mastodon background workers"
    start-stop-daemon --stop \
        --pidfile=${pidfile} \
    eend $?
}

Example init script file for the streaming API, to be placed in /etc/init.d/mastodon-streaming:

#!/sbin/openrc-run

name="Mastodon streaming API service"
root="/home/mastodon/live"

depend() {
    use net
}

start() {
    ebegin "Starting Mastodon streaming API"

    cd $root

    start-stop-daemon --start \
        --background --quiet \
        --chdir "${root}" \
        --user="mastodon" \
        --make-pidfile --pidfile=${root}/streaming.pid \
        --exec /usr/bin/env -- NODE_ENV=production PORT=4000 /usr/bin/npm run start
    eend $?
}

stop() {
    ebegin "Stopping Mastodon streaming API"
    start-stop-daemon --stop \
        --pidfile=${root}/streaming.pid \
    eend $?
}

This allows you to rc-update add mastodon-web && rc-update add mastodon-sidekiq && rc-update add mastodon-streaming and service mastodon-web start && service mastodon-sidekiq start && service mastodon-streaming start to get things going.

Apache

Setting up Mastodon behind Apache is possible as well, although you will need to enable mod_proxy_wstunnel beforehand. The configuration is then pretty straightforward.
