Below is a brief explanation of adding a unix user and giving him sudo privileges. The procedure on the AMP is the same as it would be on a 'normal' unix installation, so there are a variety of print and web resources available that go into more detail.
The command to add a user is simply useradd. So:
would add a user account named awsupport. There are a lot of different options you can give the useradd command, and you can read the manual page for a breakdown (man useradd). The account is disabled by default unless you provide a password as an argument to useradd, but the root user can change a user account password at any time using the passwd command:
will prompt for the new password and then the confirmation. Giving the user sudo privileges requires adding an entry to the /etc/sudoers file. You can do so by running
and then adding one of the below lines, the 1st will prompt for password, the 2nd will not:
## Allows people in group wheel to run all commands
awsupport ALL=(ALL) ALL
## Same thing without a password
awsupport ALL=(ALL) NOPASSWD: ALL
As always, you can check the man file for sudoers (man sudoers) to read about different configuration options.
