Periodically new versions of the VisibleThread server software become available, for instance you may wish to upgrade from Server version 2.x to 2.y
This section is for those performing such an upgrade.
Red Hat and Ubuntu deployments each have a different upgrade mechanism. Each one will be covered below
Upgrading a VisibleThread Docs Ubuntu deployment
VisibleThread product upgrades are shipped as upgrade files with the extension '.tar.gz', for example Upgrade-2.14-build-2168.tar.gz
Download details for each upgrade are emailed to all VisibleThread customers as soon as the upgrade becomes available. If you are missing details of where to retrieve an upgrade please contact our support team.
When you have downloaded your upgrade file, it needs to be added to the /home/visiblethread/VisibleThreadTools/upgrade folder on the VisibleThread Virtual Appliance.
Uploading the upgrade file to the Virtual Appliance
You can upload the upgrade file to the Virtual Appliance via SSH (Secure SHell) using port 22. The easiest way to do this is to use one of a number of freely available tools such as the FileZilla client (http://filezillaproject.org/) or WinSCP (http://www.winscp.net). The next section outlines the detailed steps to complete this:
Connect to your Virtual Appliance using the following details:
- IP address: The IP Address of your Virtual Apppliance/VisibleThread Server.
- username: visiblethread
- Password: password (unless changed when completing deploying the VisibleThread server)
- Port: 22
- Once connected navigate to the /home/visiblethread/VisibleThreadTools/upgrade folder.
- Upload the upgrade file to this folder.
Applying the upgrade to the Virtual Appliance
Note: Applying the upgrade will bring down the VisibleThread application for several minutes.
The VisibleThread Virtual Appliance contains an upgrade script that will perform an upgrade of the Virtual Appliance. To run this script log on to the VisibleThread Virtual Appliance console and execute the following commands:
screen ./vt-upgrade.sh upgrade/<upgradefilename.tar.gz>
Note: You may be prompted for the "visiblethread" user password when running this command. This will unpack the archive, deploy the upgrade files and restart the application.
Upgrading a VisibleThread Docs Red Hat deployment
Upgrades are distributed in the form of a new rpm package. You will have been provided details of where to download this upgrade file from VisibleThread support via e-mail. Mail firstname.lastname@example.org should you not have received these details.
Download the new .rpm to your Red Hat server, and to install it :
yum install -y visiblethread-docs-3.2.2.x86_64.rpm
This will install the new application version and restart the services.
