This is useful for Capistrano deployments when you need to start rake process which doesn’t run as daemon.
When you start daemons you will usually do this:
task :start_app, :roles => :app_servers do
run "export RAILS_ENV=production && cd #{deploy_to}/current/ &&/usr/local/bin/rake app:start"
end
This may hold Capistrano session and prevent Capistrano to complete remaining tasks. Here is how you can prevent it:
task :start_app, :roles => :app_servers do
run "export RAILS_ENV=production && cd #{deploy_to}/current/ && nohup /usr/local/bin/rake app:start >/dev/null 2>&1 &"
end
This is of course same as running any other kind of command:
user@computer:$ nohup COMMAND >/dev/null 2>&1 &
