shuiqingliu opened a new pull request, #10390:
URL: https://github.com/apache/inlong/pull/10390
Fixes #10261
### Motivation
Implement SSH key-based authentication when installing the agent via SSH.
The implementation plan is as follows:
1. On the dashboard node, add an option to distinguish between
username/password and SSH key authentication when selecting the SSH method. For
SSH key authentication, the user also needs to input the username, port, and IP
information.
2. When the user selects SSH key authentication, the dashboard actively
calls the SSH key retrieval interface.
3. If the manager node does not have an SSH key pair, it calls ssh-keygen
to generate one. If a key pair already exists, it is returned directly.
4. When executing the installation command, if no user password is
provided, the installation defaults to using SSH key authentication.
### Modifications
* Added an SSH key generation interface.
* Modified the remote command execution method to support SSH key
authentication.
* When the user authenticates via SSH key, the password is empty, so the
remote command execution method was modified to support nullable parameters.
