Production guide ================ ## Nginx Regardless of whether you go with the Docker approach or not, here is an example Nginx server configuration: ```nginx map $http_upgrade $connection_upgrade { default upgrade; '' close; } server { listen 443 ssl; server_name example.com; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; keepalive_timeout 70; sendfile on; client_max_body_size 0; gzip off; root /home/mastodon/live/public; add_header Strict-Transport-Security "max-age=31536000; includeSubDomains"; location / { try_files $uri @proxy; } location @proxy { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_pass_header Server; proxy_pass http://localhost:3000; proxy_buffering off; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; tcp_nodelay on; } location /api/v1/streaming { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_pass http://localhost:4000; proxy_buffering off; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; tcp_nodelay on; } error_page 500 501 502 503 504 /500.html; } ``` ## Running in production without Docker It is recommended to create a special user for mastodon on the server (you could call the user `mastodon`), though remember to disable outside login for it. You should only be able to get into that user through `sudo su - mastodon`. ## General dependencies curl -sL https://deb.nodesource.com/setup_4.x | sudo bash - sudo apt-get install imagemagick ffmpeg libpq-dev libxml2-dev libxslt1-dev nodejs sudo npm install -g yarn ## Redis sudo apt-get install redis-server redis-tools ## Postgres sudo apt-get install postgresql postgresql-contrib Setup a user and database for Mastodon: sudo su - postgres psql In the prompt: CREATE USER mastodon CREATEDB; \q ## Rbenv It is recommended to use rbenv (exclusively from the `mastodon` user) to install the desired Ruby version. Follow the guides to [install rbenv][1] and [rbenv-build][2] (I recommend checking the [prerequisites][3] for your system on the rbenv-build project and installing them beforehand, obviously outside the unprivileged `mastodon` user) [1]: https://github.com/rbenv/rbenv#installation [2]: https://github.com/rbenv/ruby-build#installation [3]: https://github.com/rbenv/ruby-build/wiki#suggested-build-environment Then once `rbenv` is ready, run `rbenv install 2.3.1` to install the Ruby version for Mastodon. ## Git You need the `git-core` package installed on your system. If it is so, from the `mastodon` user: cd ~ git clone https://github.com/Gargron/mastodon.git live cd live Then you can proceed to install project dependencies: gem install bundler bundle install --deployment --without development test yarn install ## Configuration Then you have to configure your instance: cp .env.production.sample .env.production nano .env.production Fill in the important data, like host/port of the redis database, host/port/username/password of the postgres database, your domain name, SMTP details (e.g. from Mailgun or equivalent transactional e-mail service, many have free tiers), whether you intend to use SSL, etc. If you need to generate secrets, you can use: rake secret To get a random string. If you are setting up on one single server (most likely), then `REDIS_HOST` is localhost and `DB_HOST` is `/var/run/postgresql`, `DB_USER` is `mastodon` and `DB_NAME` is `mastodon_production` while `DB_PASS` is empty because this setup will use the ident authentication method (system user "mastodon" maps to postgres user "mastodon"). ## Setup And setup the database for the first time, this will create the tables and basic data: RAILS_ENV=production bundle exec rails db:setup Finally, pre-compile all CSS and JavaScript files: RAILS_ENV=production bundle exec rails assets:precompile ## Systemd Example systemd configuration for the web workers, to be placed in `/etc/systemd/system/mastodon-web.service`: ```systemd [Unit] Description=mastodon-web After=network.target [Service] Type=simple User=mastodon WorkingDirectory=/home/mastodon/live Environment="RAILS_ENV=production" Environment="PORT=3000" ExecStart=/home/mastodon/.rbenv/shims/bundle exec puma -C config/puma.rb TimeoutSec=15 Restart=always [Install] WantedBy=multi-user.target ``` Example systemd configuration for the background workers, to be placed in `/etc/systemd/system/mastodon-sidekiq.service`: ```systemd [Unit] Description=mastodon-sidekiq After=network.target [Service] Type=simple User=mastodon WorkingDirectory=/home/mastodon/live Environment="RAILS_ENV=production" Environment="DB_POOL=5" ExecStart=/home/mastodon/.rbenv/shims/bundle exec sidekiq -c 5 -q default -q mailers -q pull -q push TimeoutSec=15 Restart=always [Install] WantedBy=multi-user.target ``` Example systemd configuration file for the streaming API, to be placed in `/etc/systemd/system/mastodon-streaming.service`: ```systemd [Unit] Description=mastodon-streaming After=network.target [Service] Type=simple User=mastodon WorkingDirectory=/home/mastodon/live Environment="NODE_ENV=production" Environment="PORT=4000" ExecStart=/usr/bin/npm run start TimeoutSec=15 Restart=always [Install] WantedBy=multi-user.target ``` This allows you to `sudo systemctl enable /etc/systemd/system/mastodon-*.service` and `sudo systemctl start mastodon-web.service mastodon-sidekiq.service mastodon-streaming.service` to get things going. ## Cronjobs I recommend creating a couple cronjobs for the following tasks: - `RAILS_ENV=production bundle exec rake mastodon:media:clear` - `RAILS_ENV=production bundle exec rake mastodon:push:refresh` - `RAILS_ENV=production bundle exec rake mastodon:feeds:clear` You may want to run `which bundle` first and copypaste that full path instead of simply `bundle` in the above commands because cronjobs usually don't have all the paths set. The time and intervals of when to run these jobs are up to you, but once every day should be enough for all. You can edit the cronjob file for the `mastodon` user by running `sudo crontab -e mastodon` (outside of the mastodon user). ## Things to look out for when upgrading Mastodon You can upgrade Mastodon with a `git pull` from the repository directory. You may need to run: - `RAILS_ENV=production bundle exec rails db:migrate` - `RAILS_ENV=production bundle exec rails assets:precompile` Depending on which files changed, e.g. if anything in the `/db/` or `/app/assets` directory changed, respectively. Also, Mastodon runs in memory, so you need to restart it before you see any changes. If you're using systemd, that would be: sudo systemctl restart mastodon-*.service
