capistrano problem

Question

I am having a problem with deploying my application to my server.

I have msysgit, github and capistrano installed and working.

I have successfully pushed my app to github and can successfully run cap deploy:setup to setup on my server from my local machine.

BUT..

When I run cap deploy:cold it asks me for my passphrase to connect to github repo then it asks it again to connect to my server but then it gives me an error permission denied (public key) and rools back.

It seems like this is an error with my keys but how can it then connect to my server to do the cap deplo:setup ?

My public keys are the same in both github and my server is this correct ?

Also when running cap deploy:setup it asks me for my user server password is this correct ?

Please help as this has delayed me for days already

This is the error:

If I add this to my deploy.rb file

set :ssh_options, {:forward_agent => true}
on :start do    
  `ssh-add`
end

I get this different error

You should have on your server (where you want deploy) installed yours access keys for git server.

You should have yours key files (with chmod 600):

id_rsa

id_rsa.pub

in ~/.ssh directory (with chmod 700) on server in deploy user home

you probably have that keys only on your local development computer.

You can add for your deploy file hook for 'setup:cold' where will be automated upload of your local keys files.

what so you have a public and private key on both my local machine and my server ? should these be exactly the same ? i thought you just have public private on local machine and then copy the pulic to server ? the thing is aswll is that i can ssh user@server and enter my pass phrase and it will conect to the server this way. ??? – Jul 24 '09 at 11:24
you want deploy using git, and capistrano want pull code from server side, not from your computer and that is reason why you should have git access keys on server account. You must divide ssh access to server from your computer and access to git server from server (to get last sources). You dont uploading sources from local computer, you requesting deployment via git on server side. – Andrzej Śliwa Jul 24 '09 at 12:22
in theory capistrano supports ssh agent so that local keys can be used and you don't need your own keys on the deployment server. In fact this is the ideal scenario. However, capistrano appears to be somewhat broken on this feature – Factor Mystic Sep 12 '11 at 19:51

This question is really old, but I just encountered the same problem again on a windows 7 machine. You should add forward_agent and the location of your ssh key to your deploy config file: Here is my fix at config/deploy.rb:

set :ssh_options,   :forward_agent => true 
set :ssh_options,   :keys => %w(c:/Users/USERNAME/.ssh/id_rsa)

Besides that, the best solution would be to develop rails applications (and to use capistrano) in a linux environment. This would avoid tons of such tricks, wordrounds and it would save plenty of time :)

It's not needed to have the ssh keys to access the repository server on the deploy mahcine. You can activate the SSH forward_agent, to make the ssh_agent follow you from machine to mache. To do this with capistrano, you can add this line to the deploy.rb file

ssh_options[:forward_agent] = true
