问题 We have a EC2 instance, and our capistrano setup requires ssh. To connect through ssh normally, I use a .pem file for connecting to the server. how do I utilize this .pem file when using capistrano to deploy? 回答1: In deploy.rb set these configuration values: default_run_options[:pty] = true ssh_options[:forward_agent] = true ssh_options[:auth_methods] = ["publickey"] ssh_options[:keys] = ["/path/to/key.pem"] For Capistrano 3 use: set :pty, true set :ssh_options, { forward_agent: true, auth

( irrespective of which subnet you are). -> Hence if you want to migrate EC2 instance with the same IP address, you need to assign

问题 Can we stop an AWS windows server EC2 instance of a development environment when there is no activity in it, say after 2 hours of inactivity? I am having trouble identifying whether any user is connected to the server virtually.
