connection failed for: localhost (Errno::ECONNREFUSED: Connection refused - connect(2))

问题

I am using capistrano 2.15.5 for my rails application deployment. I am using localhost for server and have also tried with 127.0.0.1 in place of localhost. After running *cap production deploy:setup* the error that i am getting is: **Errno::ECONNREFUSED: Connection refused - connect(2)**. After searching for it i found out ECONNREFUSED means the client couldn't make a TCP connection to the server, either because it's down, or its DNS is not resolving..

how to fix this issue? thanks.

You have to add your ssh key in server's ssh authorize keys
