Teleport appears to already be running on this host

Hello,
I have some problem to install teleport on a proxmox server client.
I generate the script by the Teleport resorces web configuration page.
When I try to run the script :
sudo bash -c "$(curl -fsSL https://servername/scripts/cdeb5b9fdf9a6c26182fe636352c424a/install-node.sh)", I have the error:

Warning: Teleport appears to already be running on this host (pid: 2549)

This script does not overwrite any existing settings or Teleport installations.
Please clean up by running any of the following steps as necessary:

• stop any running Teleport processes
  • pkill -f teleport
• remove any data under /var/lib/teleport, along with the directory itself
  • rm -rf /var/lib/teleport
• remove any configuration at /etc/teleport.yaml
  • rm -f /etc/teleport.yaml
• remove any Teleport binaries (teleport tctl tsh) installed under /usr/local/bin
  • rm -f /usr/local/bin/teleport /usr/local/bin/tctl /usr/local/bin/tsh
    Run this installer again when done.

I have tryed to delete all the folders and kill the service but still same error.
I have several servers with Teleport SSH service that work fine, Just two of them are not working.....
Any Idea?
Tks

Did you confirm the binaries are removed?

[flayy73]

Yes, confirmed.
Anyhow, I solved the problem by connecting to the cluster manually (tsh), generating the token by tctl and starting the service (node type). Now the SSH connection works.
Now I have another problem to solve:
The teleport configuration is for an SSH connection (node type). I would like to add some web_app to the same client, and if I edit the teleport.yaml file, add the web app configuration, and restart the service, the connection is not accepted by the cluster because, of course, the token is not valid anymore (was generated for the SSH connection only).
I'm struggling to find a tutorial or a clear procedure on how to do that, but without a solution.
I know that I have to generate a new token, but is not clear how to add this to my existing teleport.yaml configuration.
Thank you !

If you run tctl tokens add --type=node,app on your Teleport auth server, this will give you a new token which is valid for both the SSH and application services.

Take this token and copy it into the auth_token or token_name section of the /etc/teleport.yaml config file on your node/app server, then restart Teleport:

teleport:
  join_params:
    method: token
    token_name: 2UcxhLA9n7KbrHUhZJUGiD9jPN1dT87m
...
ssh_service:
  enabled: yes
...
app_service:
  enabled: yes
...
