Calculating external PostgreSQL DB requirements

Administrators can use this requirements section as a guide to evaluate your server hardware requirements. Because server load is difficult to predict, live testing is the best way to determine what hardware the DMC will require in production.

Pre-install requirements

Aside from a PostgreSQL 10 or 11 database or AWS RDS, the DMC also requires the following:

  1. A non-root user with sudo access.

User and group setup example

sudo useradd -m datical
sudo passwd datical
sudo usermod -aG wheel datical

In this example, the wheel group has sudo access, so datical is just added to that group. Depending on your site's sudo policies, you may need to add your username to a different group or add it directly to /etc/sudoers.

Tip: Create a new user or add an existing user to a group on your own before starting the installation as the installation scripts and installers do not create them for you.

  1. On the provisioned machine, ensure the following ports are opened: 80, 443, and 8080, and ensure no other applications are using the ports on the local system.

Creating the Database and Database user for the DMC

The DMC requires it’s own PostgreSQL database and owner database credentials to work correctly. Follow these steps to create these credentials:

  1. Create a database. To create a database, run:
create database <databasename>
  1. Create a user. To create a user, run:
create user <username> with password <password>
  1. Assign user ownership to the database. To assign user ownership, run:
alter database <databasename> owner to <username>

Now, use the database name, username, and password where indicated in the application installation instructions.
