Using rvmsudo with Capistrano

Question

I am trying to configure capistrano to quickly deploy my rails3 application. I am new to rails.

Everything works as it should, except that I am trying to restart the stand-alone passenger server.

I run redmine on the same server, so I ran http://blog.phusion.nl/2010/09/21/phusion-passenger-running-multiple-ruby-versions/ to run several versions of ruby ​​/ rails. This works fine until I try to get capistrano to restart the passenger server.

The problem is that 'sudo' does not pass the environment settings through (as found on: sudo changes PATH - why? )

Everything works if I can use 'rvmsudo' instead of 'sudo' since rvmsudo conveys the correct environment information. But, if I use "rvmsudo" in my Captistrano deployment, it hangs waiting for my sudo password.

I would like to implement try_rvmsudo, which works exactly the same as try_sudo, where it sends the password if asked. but I can not find any information about this.

here is the restart command I'm trying to use:

desc "Restart Passenger server" task :restart, :roles => :app, :except => { :no_release => true } do run <<-CMD if [[ -f #{release_path}/tmp/pids/passenger.#{passenger_port}.pid ]]; then cd #{deploy_to}/current && #{passenger_path}passenger stop -p #{passenger_port} --pid-file #{release_path}/tmp/pids/passenger.#{passenger_port}.pid; fi CMD # restart passenger standalone on the specified port/environment and as a daemon run "cd #{deploy_to}/current && rvmsudo #{passenger_path}passenger start -e #{rails_env} -p #{passenger_port} -a 127.0.0.1 -d --pid-file #{release_path}\ /tmp/pids/passenger.#{passenger_port}.pid" end 

And it freezes, saying:

  ** [out :: snapshotroulette.com] [sudo] password for deployer:

Ok, I found out that I can send Capistrano the sudo password first (by running the sudo command). Sudo remembers your password for a short time (default is 5 minutes). And, rvmsudo just calls sudo with some environment variables set, so it also remembers your password.

This is not very pretty, but it works:

 desc "Restart Passenger server" task :restart, :roles => :app, :except => { :no_release => true } do # Hack to have capistrano enter the sudo password (for rvmsudo later) sudo "whoami" run <<-CMD if [[ -f #{release_path}/tmp/pids/passenger.#{passenger_port}.pid ]]; then cd #{deploy_to}/current && rvmsudo passenger stop; fi CMD # restart passenger standalone on the specified port/environment and as a daemon # The sleep 1 is to give the server enough time to spawn. The session was closing before it spawned, so it never actually spawned run "cd #{deploy_to}/current && rvmsudo passenger start -e #{rails_env} -p #{passenger_port} -a 127.0.0.1 -d --pid-file #{release_path}/tmp/pids/passeng\ er.#{passenger_port}.pid && sleep 1" end 

Any other solutions are welcome!

The rvmsudo hanging capistrano issue seems to have been fixed in later versions of rvm. For my launch of "rvm get stable" on target computers, the problem is fixed.
