How To

Restarting Mastodon

The Mastodon server consists of a standard web server which proxies certain requests through to each of three systemd processes:

• mastodon-sidekiq.service
• mastodon-streaming.service
• mastodon-web.service

In some environments, these may be started, stopped, or restarted with a single command: systemctl <start/stop/restart> mastodon-*.service

Recently, we have found that start often does not work with the * wildcard, and the processes must be started individually:

• systemctl start mastodon-sidekiq.service
• systemctl start mastodon-streaming.service
• systemctl start mastodon-web.service
