Objective

To perform certain administrative functions on your server (e.g. installing packages), you'll need to have a high level of user access. On Linux servers, this access is called "root".

This guide will show you how to become the root user and create a password for the root account.

Requirements

• a Public Cloud project activated
• access to the OVH Control Panel

Instructions

Changing the root password

First, establish an SSH connection to your server.

At the command line, enter a password for the admin user (for security reasons, the password will not be shown as you type it):

~$ sudo passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated 
successfully

Update repositories (Debian/Ubuntu)

To update the installed software packages on your server, type the following command at the command line:

~$ sudo apt-get update
