Step 3: Essential Configuration

Essential Configuration

Most default settings are acceptable and we should leave them unless we have a reason to make a change.

We should set the timezone of the VPS to our local area, which is Asia/Almaty, Then we can test it using the date command.

  1. Enter these commands one at a time into the terminal window.

    timedatectl set-timezone

    Tells the OS to set a specific timezone of the system. You can use any timezone from this list of available zones.

    date

    Displays the current date and time.

    sudo timedatectl set-timezone Asia/Almaty
date

    1root@vps298933:~# timedatectl set-timezone Asia/Almaty
2root@vps298933:~# date
