After the installation of Redmine on Ubuntu 20.04, you can add this features as you see fit.

Setup Pre-requisites

You need to have a running server with Ubuntu 20.04 Linux and additionally:

  • SSH user with sudo privileges – root user is also okay
  • Domain for hosting Redmine – e.g projects.example.com
  • SSL certificate if planning on having it securely – You can use Let’s Encrypt if the server is exposed to the internet with a public IP Address.

Step 1: Connect to server and update

SSH to your server:

$ ssh [email protected]

Begin to update it for latest packages to be updated in the server.

sudo apt update
sudo apt upgrade
sudo reboot

Step 2: Install MariaDB Database Server

After the update, install and configure MariaDB database server on Ubuntu 20.04 | Ubuntu 18.04.

sudo apt update
sudo apt install mariadb-server

Confirm it is working:

$ sudo mysql -u root

Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or g.
Your MariaDB connection id is 57
Server version: 10.3.22-MariaDB-1ubuntu1 Ubuntu 20.04

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

MariaDB [(none)]>

Step 3: Create Database for Redmine

With database server installed on Ubuntu, let’s create database and user for Redmine project management platform.

$ sudo mysql -u root -p
CREATE DATABASE redmine CHARACTER SET utf8mb4;
GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost' IDENTIFIED BY '[email protected]';
FLUSH PRIVILEGES;
EXIT;

Confirm redmine database user can login to MySQL Shell with configured password.

$ mysql -u redmine -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or g.
Your MariaDB connection id is 59
Server version: 10.3.22-MariaDB-1ubuntu1 Ubuntu 20.04

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

MariaDB [(none)]> SHOW DATABASES;
 -------------------- 
| Database           |
 -------------------- 
| information_schema |
| redmine            |
 -------------------- 
2 rows in set (0.000 sec)

MariaDB [(none)]> QUIT
Bye
