Updating NetVizura requires internet access

NetVizura requires working connection to the internet to install required update. After update is successful you can turn off internet access for 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 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 (fastest way is to delete old raw data files in archive which is usually located in /var/lib/netvizura/flow/archive)

  2. Make directory where the update package would be downloaded:

    mkdir /tmp/update-x.y.z

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

  3. Download the update package from NetVizura site
  4. Move updater package to /tmp/update-x.y.z directory

    On Centos6
    mv netvizura-x.y.z-update-rpm-rhel6.tgz /tmp/update-x.y.z
    On Centos 7
    mv netvizura-x.y.z-update-rpm-rhel7.tgz /tmp/update-x.y.z
  5. Go to update directory: 

    cd /tmp/update-x.y.z 
  6. Unpack updater package with: 

    On CentOS 6
    tar -xzf netvizura-x.y.z-update-rpm-rhel6.tgz
    On CentOS 7
    tar -xzf netvizura-x.y.z-update-rpm-rhel7.tgz
  7. Execute:

    ./update.sh
  8. Optional: Install Elasticsearch

    On Centos 6
    wget https://www.netvizura.com/files/products/general/downloads/elasticsearch-prerequisites-centos6.sh --output-document=/tmp/elasticsearch-prerequisites-centos6.sh
    bash /tmp/elasticsearch-prerequisites-centos6.sh
    On Centos 7
    wget https://www.netvizura.com/files/products/general/downloads/elasticsearch-prerequisites-centos.sh --output-document=/tmp/elasticsearch-prerequisites-centos.sh
    bash /tmp/elasticsearch-prerequisites-centos.sh

    To learn more about why this is an optional step at the moment read Why is Elasticsearch currently just an option?
