After completing the prerequisites, login as root user with your root username & password via SSH client (e.g. Putty – You can get Putty from https://www.putty.org ) or VNC console available in your Alibaba Cloud account dashboard.
In the first step, you will add a new user and give it sudo privileges. Sudo privileges will allow this username to make administrative changes on system when required. This user will be used to login from via SSH for everyday use. Once you have added this user, to keep your server secure from various attacks, you will disable the remote root access to root user.

Now set your desired password and retype your desired password. Then, enter your full name, room number, work phone, home phone, and other. After entering the information, hit Enter key. To confirm the data is correct, type 'Y' and hit Enter key.
Sometimes by default the second line %sudo ALL=(ALL:ALL) ALL is commented (starting with hash #), due to which even after adding username to sudoers, it gives error on using sudo. To prevent this issue, if this line starts with '#' sign, remove this symbol and save the changes by typing :x and then hit Enter key to save.
# adduser aareez sudo
