How to run script as another user without password

问题:

I have script.sh that must be run as user2. However, this script can only be run under user1 in my application.

I would like the following command to run:

su user2 -C script.sh

but be able to run without password.

I also want this to be very restrictive, as in user1 can only run script.sh under user2 and nothing else.

I've tried doing this with sudoers file and just got endlessly confused after hours of trying.

If somebody can provide an explicit example of how this can be accomplished (instead of something generic like use sudoers), it would be greatly appreciated.

回答1:

Call visudo and add this:

user1 ALL=(user2) NOPASSWD: /home/user2/bin/test.sh

The command paths must be absolute! Then call sudo -u user2 /home/user2/bin/test.sh from a user1 shell. Done.

回答2:

try running:

su -c "Your command right here" -s /bin/sh username

This will run the command as username given that you have permissions to sudo as that user.
