Question

I am using putty to login to my ec2 instance. When i typed root it asked me to login as ec2-user.

Authenticating with public key “imported-openssh-key” Please login as
the ec2-user user rather than root user.

when i did login as ec2-user and tried to run commands like

yum install httpd

it says

Loaded plugins: fastestmirror, priorities, security, update-motd You
need to be root to perform this command.

I am running the instance for the first time. I tried searching through the amazon aws help section and google. Not able to find the solution.

Answer 1

To switch to a root shell, run the command:

su

If you want to execute a command as root without switching to a root shell, you can use:

sudo yum install httpd
