Prerequisite
This guide assumes you have a running Amazon Linux 2 server with access to the repositories (repos).

Minimum Server Spec

12GB RAM
2 CPU Cores
220GB disk

Note: VT Writer requires port 443 and port 22(Optional for SSH).
VT Writer requires 'sudo su' permission to install correctly.

Note: Attached at the end of the article is a sudoers file. It can be referenced to give a new OS user the minimum required permissions to install the rpm file. If you want to copy/paste the contents of the file into a sudoers file in /etc/sudoers.d/ you will have to either update the user in the attached file from vtuser to the username you will create or create a user with the same name.

Download the VT Writer rpm file to the AWS Instance (alternatively you can download the files at https://visiblethread.s3.amazonaws.com/public/download/visiblethread-api-1.0.4.all.rpm and https://visiblethread.s3.amazonaws.com/public/download/visiblethread-readability-5.0.2-1.x86_64.rpm then use an FTP/SCP client to transfer it to your instance):

VT API:
curl -O https://visiblethread.s3.amazonaws.com/public/download/visiblethread-api-1.0.4.all.rpm
md5sum ccf1a6943770113236202d0623a4bf2d

VT Writer:
curl -O https://visiblethread.s3.amazonaws.com/public/download/visiblethread-readability-5.0.2-1.x86_64.rpm
md5sum 96c6a4bc6eb20ab0a049fff5ec8eba88
 

Install Postgresql 14

VT Writer rpm does not have a dependency on PostgreSQL. However, VT Writer does require PostgreSQL to function correctly. We support PostgreSQL version 11 - 15 but recommend using a minimum version of PostgreSQL 14. The below instructions are how to install PostgreSQL 14 prior to the VT Writer install.

Enable the Postgresql 14 repository and install the Postgresql packages:

sudo amazon-linux-extras enable postgresql14
sudo yum install -y postgresql-server postgresql-contrib

Enter Postgresql bash shell and initialize the DB:
sudo su - postgres
/usr/bin/postgresql-setup --initdb

Exit the Postgresql bash shell:
exit

Enable and start Postgresql service:
sudo systemctl enable --now postgresql

Verify service is active:
systemctl status postgresql

Install Java17

sudo yum install -y java-17-amazon-corretto

Install VT API rpm:

sudo yum install -y visiblethread-api-1.0.4.all.rpm

Install VT Writer rpm:

sudo yum install -y visiblethread-readability-5.0.2-1.x86_64.rpm
