Our plugins are easy to install and do not change Redmine database data. However, we recommend a full back up before the installation. In common case it is just copying unarchived plugin to your redmine/plugins/ folder. Some plugins, however, may require specific Ruby gems or/and database tables.
Below you will find common steps for any plugin installation (all commands should be executed from redmine app root folder ex. /var/www/redmine, that folder contains config.ru file)
Go to Redmine's root folder
cd /var/www/redmine
Copy and unarchive plugin
cp redmine_questions-[version]-light.zip plugins/ cd plugins unzip redmine_questions-[version]-light.zip
Install required gems
cd /var/www/redmine bundle install --without development test --no-deployment
Migrate plugin's tables
bundle exec rake redmine:plugins NAME=redmine_questions RAILS_ENV=production
Restart Redmine app
For Phussion Passenger just touch restart.txt file
touch tmp/restart.txt
