Configure remote interpreters using SSH
RubyMine allows you to configure a remote Ruby interpreter by using SSH access and work with applications deployed on a remote server. This can be useful to run or debug a remote application, perform tests, and so on. Make sure that the following prerequisites are met for a remote server before configuring a remote interpreter:
SSH access is enabled.
The Ruby interpreter is installed.
Remote project sources are synchronized with local ones (for example, by using Capistrano or a remote server configuration).
You can now follow the steps below to configure a remote interpreter using SSH:
Open the Settings/Preferences dialog Ctrl+Alt+S, go to the Language & Frameworks | Ruby SDK and Gems page.
Click the
and select New remote… in the drop-down: 
-
In the invoked dialog, select SSH Credentials and specify the required parameters depending on Authentication type:
Host/Port: The hostname/IP address and port used to connect to a remote machine.
User name: The username used to authenticate on a remote machine.
Authentication type: In this field, select the Password value to authenticate a user with a password.
Password: Specify a password used to access a remote machine.
Ruby or version manager path: Here you should specify the path to the Ruby interpreter or the version manager executable.
Host/Port: The hostname/IP address and port used to connect to a remote machine.
User name: The username used to authenticate on a remote machine.
Authentication type: In this field, select Key pair.
Private key file: Specify a path to a private key file stored on a local machine.
Passphrase (optional): Specify a passphrase used for the specified private key.
Ruby or version manager path: Here you should specify the path to the Ruby interpreter or the version manager executable.
Host/Port: The hostname/IP address and port used to connect to a remote machine.
User name: The username used to authenticate on a remote machine.
Authentication type: In this field, select OpenSSH config and authentication agent to use ssh-agent running on a local machine.
Ruby or version manager path: Here you should specify the path to the Ruby interpreter or the version manager executable.
After you have specified all the settings, click OK.
(Optional) If you specified a path to the version manager executable in the previous dialog, RubyMine suggests selecting the Ruby interpreter used to run a remote application.
