# Using SSH on Linux/Unix Nodes
Rundeck allows users to dispatch jobs to remote Linux/UNIX servers to manage and automate any task using Rundeck workflows. The most common protocol for connecting to Linux/Unix servers is SSH. This is an example of how to add a remote node and configure Rundeck to use SSH to connect to it.
Note: If this is the first time adding remote nodes. It is suggested to review the Rundeck Tutorial before adding remote SSH nodes. This exercise assumes some experience with Linux, SSH Keys, and Rundeck basics covered in the Tutorial.
This documentation is for use with the Welcome Projects on non-production instances. It is strongly recommended to follow best practices when generating, managing and configuring SSH keys and access. For detailed configuration of SSH use this documentation.
# Configuring Rundeck
Rundeck can store the authentication keys necessary to authenticate to our Linux example host in Rundeck’s built-in Key Storage.
- Click on the System Menu (gear icon) and choose Key Storage.
- Click on the Add or Upload a Key button to create a New entry in the Rundeck Key Storage.
- For Key Type select
- Add Rundeck instance private key file content in Enter text. The key is located at
- In the Storage path field it’s possible to define specific subfolders for the keys if needed, for this example just leave it blank.
- In the Name textbox enter a key name that corresponds to the Rundeck host, in this example is just
rundeck(now the Key Storage entry is
# Adding Nodes
Now, it’s time to add the remote node.
# Running Commands on Nodes
Let’s dispatch some commands!
- Clicking on the "Nodes" tab (left menu) and using the drop-down to choose Select All Nodes will display all the nodes that have been configured. The screenshot below shows the listing with 2 nodes (the Rundeck node and the node added recently).
- To select the node created earlier, put the name in Nodes textbox; In this case,
node1and press Enter key, now the node is selected.
- In the Enter a command textbox put a command, e.g.:
df, and click on the Run on 1 Node green button.
Congratulations! A remote SSH node to dispatch commands and jobs is setup in Rundeck. Stay tuned to the next blog entry where we build a job to execute on this Node.
