ruby on rails - Amazon EC2 + Capistrano + Git: Permission denied (publickey) -

when deploy rails app amazon ec2 server using capistrano, get

** [ip.compute-1.amazonaws.com :: out] permission denied (publickey). ** [ip.compute-1.amazonaws.com :: out] fatal: remote end hung unexpectedly 

while executing the

git clone 

command.

i think has github keys, don't know how set up. grateful every advise!

thanks!

edit:

i generated new key on github, put id_rsa.pub , on ec2 server created file .ssh/authorized_keys key, still doesn't work.

what's wrong that?

to use ssh agent:

ssh_options[:forward_agent] = true 

to use pem file:

ssh_options[:auth_methods] = ["publickey"] ssh_options[:keys] = ["/path/to/file.pem"] 

to enable agent in local

$ ssh-add 

you have execute command each time, don't know scope of 'each time', added ssh-add run each time open new tab in terminal echo ssh-add >> ~/.bashrc, depending in os , configuration.

the process, far understand this:

1. you have ssh-agent in local
2. you connect server deploying pem file, ssh, time through capistrano
3. remote server uses agent use key checkout git repo inside deploy machine.
