This guide assumes you have a running RHEL server with access to the Red Hat repositories (repos).
Minimum Server Spec
2 CPU Cores
The Red Hat repos are typically made available via two methods:
⦁ an active Red Hat subscription – typically used when RHEL runs on-prem, OR
⦁ Red Hat Update Infrastructure (RHUI) – available with cloud providers (e.g. Azure and AWS) to mirror Red Hat-hosted repos and automatically make them available to official RHEL cloud VMs.
Note: VT Writer requires port 443 and port 22.
VT Writer requires 'sudo su' permission to install correctly.
Note: Deployments have been tested on RHEL versions 7.2, 7.3, 7.4, 7.5, 7.6, 7.8
Deployments have been tested on VMware ESX Vsphere, Hyper-V, Azure, AWS
VT API and Writer .rpm has some dependencies (httpd, openssl, java, postgres) that are available in the Red Hat repos. For Postgres 10, we require that the Red Hat Software Collections (RHSCL) repository be enabled.
Note: The steps to add the Postgres 10 RHSCL repository may depend on your environment The repository is named differently depending on how you access repos. Below are the common commands to enable the RHSCL repo in different environments:
|Red Hat Subscription (typically on-prem)||sudo subscription-manager repos --enable rhel-server-rhscl-7-rpms|
|AWS||sudo yum-config-manager --enable rhel-server-rhui-rhscl-7-rpms|
|Azure||sudo yum-config-manager --enable rhui-rhel-server-rhui-rhscl-7-rpms|
To verify that the above command worked:
1. run sudo yum repolist
2. look for an entry like “Red Hat … RHSCL” or “Red Hat Software Collections…”
Deploying the VT Writer RPM
The VT Writer and API .rpm's are available to download here:
To verify that the download completed successfully you can check the md5 hash :
To install run the following commands:
yum install -y visiblethread-api-0.24-1.x86_64.rpm
yum install -y visiblethread-readability-2.6.1-1.x86_64.rpm
After installing these packages your VT Writer server is now ready for use !
