I have one forum using Discourse, as a test for this new platform, for OS I use CentOS. Discourse official documentation to updating the site is using Ubuntu so there are a few changes need to be done for CentOS.
My SSH login name is Discourse and the installation folder is inside the Discourse folder, example url
Here's how to update Discourse to the latest version:
# Run these commands as the discourse user bluepill stop bluepill quit # Back up your install DATESTAMP=$(TZ=UTC date +%F-%T) pg_dump --no-owner --clean discourse_prod | gzip -c > ~/discourse-db-$DATESTAMP.sql.gz tar cfz ~/discourse-dir-$DATESTAMP.tar.gz -C /home/discourse discourse # Get the latest Discourse code cd discourse git checkout master git pull git fetch --tags # To run on the latest numbered release instead of bleeding-edge: # git checkout latest-release # Merge the sample configuration just in case if there is an update. Run these commands as the discourse user diff -u config/discourse_defaults.conf config/discourse.conf diff -u config/discourse.pill.sample config/discourse.pill diff -u config/nginx.sample.conf /etc/nginx/conf.d/discourse.conf # Begin upgrade bundle install --without test --deployment RUBY_GC_MALLOC_LIMIT=90000000 RAILS_ENV=production bundle exec rake db:migrate RUBY_GC_MALLOC_LIMIT=90000000 RAILS_ENV=production bundle exec rake assets:precompile RUBY_GC_MALLOC_LIMIT=90000000 RAILS_ROOT=/home/discourse/discourse RAILS_ENV=production NUM_WEBS=2 bluepill --no-privileged -c ~/.bluepill load /home/discourse/discourse/config/discourse.pill # Restart bluepill crontab -l
