Hi @FengjiangLiu,
You need password-less SSH access to this machine for the function to work properly.
Ensure that SSH keys are set up for the cryosparc_user
account to SSH between the master node and the worker node without a password. From https://cryosparc.com/docs/reference/install/#remote-access:
Set up SSH keys for password-less access (only if you currently need to enter your password each time you ssh into the compute node).
-
If you do not already have SSH keys generated on your local machine, use
ssh-keygen
to do so. Open a terminal prompt, and enter:ssh-keygen -t rsa -N "" -f $HOME/.ssh/id_rsa
Note: this will create an RSA key-pair with no passphrase in the default location.
-
Copy the RSA public key to the remote compute node for password-less login:
ssh-copy-id remote_username@remote_hostname
Note:
remote_username
andremote_hostname
are your username and the hostname that you use to SSH into your compute node. This step will ask for your password.
