    Updating CentOS 7

    CentOS uses packages that are included in repositories to manage the updates and upgrades of your CentOS installation / installed software. In this article, we show you how to update all packages on your CentOS 7 VPS, update specific software, and update your entire OS to a newer version.

    • Connect to your VPS via SSH, or the VPS console before executing the commands below, and follow the steps as root user or use sudo
       
    • Restart your VPS after updating the kernel. Changes are often not processed until your server is restarted.

    Updating all software

     

    With the command below, you update all software in CentOS 7:

    yum -y update

    -y confirms that this process may make changes to your VPS.


    Updating specific software / packages

     

    Would you rather update a specific package instead of all packages? Then you'd use the command:

    yum -y update packagename

    Replace 'packagename' with the name of the relevant package. In our article 'Installing software in CentOS 7', we explain how to find out the name of packages. For a total overview of all packages use:


    Upgrading CentOS 7

     

    Suppose you want to upgrade CentOS 7, for example from 7.5 to 7.6, then this works exactly the same as updating all your software packages:

    yum -y update

    Check the current installed version with:

    cat /etc/redhat-release
