Updating NetVizura requires internet access

NetVizura requires an active internet connection to install the required update. After the update is successful, you can turn off internet access for the NetVizura server.

When you update NetVizura, we strongly recommend performing the update in a test environment before updating your production site.

Updating NetVizura requires superuser privilege.

Step-by-step guide:

  1. Check the free space on your disk command.

    df -h

    If there is less than 8GB of free space on disk, delete some files to make at least 8GB available space (the fastest way is to delete old raw data files in the archive, which is usually located in /var/lib/netvizura/flow/archive)

  2. Download and run the script that automates the upgrade of prerequisite software:

    wget https://www.netvizura.com/files/updates/netvizura-6.1-update-prerequisites-centos.sh --output-document=/tmp/update-prerequisites-centos.sh
sudo bash /tmp/update-prerequisites-centos.sh


  3. Make a directory where the update package will be downloaded:

    mkdir /tmp/update-x.y.z

    (info) x.y.z is NetVizura version number.

  4. Download the update package from NetVizura site

  5. Move updater package to /tmp/update-x.y.z directory

    On Centos8
    mv netvizura-x.y.z-update-rpm-rhel8.tgz /tmp/update-x.y.z
    On Centos 9
    mv netvizura-x.y.z-update-rpm-rhel9.tgz /tmp/update-x.y.z

  6. Go to update directory: 

    cd /tmp/update-x.y.z

  7. Unpack updater package with: 

    On CentOS 8
    tar -xzf netvizura-x.y.z-update-rpm-rhel8.tgz
    On CentOS 9
    tar -xzf netvizura-x.y.z-update-rpm-rhel9.tgz

  8. Execute:

    ./update.sh

  9. Refresh your browser (Ctrl + F5)

  10. Check update is successful: http://<netvizura_server_ip>:8080/netvizura/#settings:license
