operation

update Mastodon partially

current-foresdon is my customized branch. if your repository tracks the tootsuite/mastodon, you must run git checkout v2.8.1 instead of git pull.

run as mastodon user:

$ cd ~/live
$ git fetch
$ git pull
$ bundle install
$ yarn install --pure-lockfile
$ RAILS_ENV=production bundle exec rails assets:precompile

edit the .env.production

add new environment variable GITHUB_REPOSITORY into .env.production if needed.

GITHUB_REPOSITORY=kedamaDQ/mastodon

stop services

i have changed the systemd service name. this is for don't stop services in production server with misunderstanding another environment servers.

run as root:

# systemctl stop foresdon-web
# systemctl stop foresdon-streaming
# systemctl stop foresdon-sidekiq

backing up datas

mount working volume if needed. run as root:

# mount /dev/vg001/lvtmp /mnt/tmp

backing up postgres and redis. run as root:

# cd /mnt/tmp
# sudo -u postgres pg_dumpall > foresdon.jp.190504.dump
# gzip foresdon.jp.190504.dump
# redis-cli lastsave
# redis-cli bgsave
# redis-cli lastsave
# cp /var/lib/redis/dump.rdb ./foresdon.jp.190504.dump.rdb
# gzip foresdon.jp.190504.dump.rdb

ℹ️ redis-cli lastsave returns timestamp when last saving data to file. if timestamp changed after redis-cli bgsave, saving is completed.

run the remained steps of updating Mastodon

$ cd ~/live
$ RAILS_ENV=production bundle exec rails db:migrate

# systemctl start foresdon-sidekiq
# systemctl start foresdon-streaming
# systemctl start foresdon-web
