How to install redmine on RHEL 8 / CentOS 8 Linux

by

Redmine is a popular open source project management web application. It supports mayor databases like MySQL and PostgreSQL as backend, and you can also change the frontend to Apache from the WEBrick (recommended for production use) webserver shipped with the installation. In this article we will install the latest Redmine on RHEL 8 / CentOS 8, using PostgreSQL as backend, but we will leave the default WEBrick as frontend, which will serve our tests perfectly.

Do not expect this process to be an easy one, nor error-free. Even following these steps to the letter, some errors will surely happen, the setup seem to handle sudo steps somewhat inconsistently – but the solutions are also included which will guide trough these errors.

In this tutorial you will learn:

  • How to install required operating system packages
  • How to setup the database
  • How to install the Redmine application
  • How to start and login to the application
