Password for ec2-user on AWS Cloud9

Question

I am trying to run $ sudo su in the terminal of AWS Cloud9. I get prompted for the password for the ec2-user. Any ideas what this might be?

Might be worth noting that prior to coming up against this issue, when trying to yum install a package, I got 'packages excluded due to repository priority protections' so I ran yum erase yum-plugin-priorities as per https://serverfault.com/questions/312472/what-does-that-mean-packages-excluded-due-to-repository-priority-protections (I'm fairly sure I had to do that with sudo but wasn't prompted for the password).

Answer 1

First you need to set your password using command

$ sudo passwd ec2-user

Then you can use the new password where ever its required
