ssh以用户身份登录并更改为root，无需sudo

Question

I have the following task for my golang code:

• The command has to be run as root user on the server remotely in bash and the command output has to be fetched in a variable.
• Logging over ssh as root is disabled.
• sudo on the server is disabled, so I have to use 'su -' and type password
• since I want to make it as automated as possible in bash, the password has to be stored inside the command

Here are the workflow actions:

1. Login via SSH (as unprivileged user) to remote host
2. Elevate to privileged 'root' user --> su -
3. Type the root password
4. run the command which root can execute
5. get to output to string on localhost and do some actions

I have Googled for days, but it seems that I cannot find a solution for this. Does anyone have a solution to this?

Answer 1

The issue you are facing is concerning interacting with the command after it has been executing.

It is quite easy to use exec.Command for non-interactive commands.

I would recommend using Expect for interaction, or the Golang equivalent located here.
