Become the root user and select a password

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

Last updated 11th October 2018

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

This guide assumes that the default user is called 'admin'.

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

Update the system (CentOS/Fedora)

To update your server's operating system, type the following command at the command line:

~$ sudo yum update

Edit a configuration file

~$ sudo vi /etc/hosts.allow

Become root

To become the root user, type the following command at the command line:

~$ sudo su -
~#

Next, enter the root password.
