How To Install Redmine on Debian 12

Install Redmine on Debian 12

In this tutorial, we will show you how to install Redmine on Debian 12. Redmine is a powerful and flexible project management and issue-tracking tool that has gained popularity for its open-source nature and extensive feature set. It is crucial to secure your Redmine installation, especially if it deals with sensitive data.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Redmine on a Debian 12 (Bookworm).


  • A server running one of the following operating systems: Debian 12 (Bookworm).
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • Make sure your Debian 12 system is connected to the internet. An active connection is essential for downloading the required packages and updates during the installation.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Redmine on Debian 12 Bookworm

Step 1. Open your terminal and log in to your server using SSH. Update the package list and upgrade your system with the following commands:

sudo apt update
sudo apt upgrade

This command updates the package list and upgrades the installed packages to their latest versions.

Step 2. Configuring the Hostname and DNS Settings.

Set the hostname of your server and update the /etc/hosts file. Replace ‘yourhostname‘ with your chosen hostname:

echo "yourhostname" | sudo tee /etc/hostname
echo " yourhostname" | sudo tee -a /etc/hosts
sudo hostname yourhostname

Step 3. Installing and Configuring the Database.

For Redmine, it’s recommended to use PostgreSQL. Install it with:

sudo apt install postgresql

Now, let’s configure PostgreSQL and create a user for Redmine. Log in to the PostgreSQL shell:

sudo -u postgres psql

Create a database and user for Redmine:

CREATE USER redmine WITH PASSWORD 'your_stong_password';
ALTER ROLE redmine SET client_encoding TO 'utf8';
ALTER ROLE redmine SET default_transaction_isolation TO 'read committed';
ALTER ROLE redmine SET timezone TO 'UTC';

Next, edit the PostgreSQL configuration to allow Redmine access. Open the configuration file:

sudo nano /etc/postgresql/13/main/pg_hba.conf

Add the following line at the end of the file:

host redmine redmine md5

Save the file and restart PostgreSQL:

sudo systemctl restart postgresql

Step 4. Installing Redmine on Debian 12.

Now download the latest stable Redmine release:

cd /opt
sudo tar -xvf redmine-5.1.0.tar.gz

Next, create a database configuration file:

cd /opt/redmine-5.1.0/config
sudo cp database.yml.example database.yml

Edit database.yml and configure the database connection:

adapter: postgresql
database: redmine
host: localhost
username: redmine
password: "your_strong_password"
encoding: utf8

Navigate to your Redmine directory and install the required gems:

cd /opt/redmine-5.1.0
sudo gem install bundler
sudo bundle install --without development test

Migrate the database schema and load default data:

sudo bundle exec rake db:migrate RAILS_ENV=production
sudo bundle exec rake redmine:load_default_data RAILS_ENV=production

Generate a secret key for Redmine:

sudo bundle exec rake generate_secret_token

Step 5. Configuring Apache Web Server.

Install Apache and enable it:

sudo apt install apache2
sudo systemctl enable apache2

Once Apache is installed, start it and enable it to start on boot:

sudo systemctl start apache2
sudo systemctl enable apache2

Next, create a new Apache virtual host configuration file:

sudo nano /etc/apache2/sites-available/redmine.conf

Add the following configuration, replacing ‘yourdomain‘ with your actual domain:

<VirtualHost *:80>
ServerName yourdomain
ServerAlias www.yourdomain
DocumentRoot /opt/redmine-5.1.0/public
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

Enable the required Apache modules and configure the proxy settings:

sudo a2enmod proxy
sudo a2enmod proxy_http

Edit your virtual host file to add proxy settings:

sudo nano /etc/apache2/sites-available/redmine.conf

Add these lines inside the <VirtualHost> block:

 ProxyPass /
ProxyPassReverse /

After that, improve security by disabling directory listing and setting up a .htaccess file:

sudo a2disconf serve-cgi-bin
sudo a2enmod rewrite
sudo nano /opt/redmine-5.1.0/public/.htaccess

Add the following:

Options -Indexes

Step 6. Installing Let’s Encrypt SSL Certificate.

Now install Certbot to obtain an SSL certificate from Let’s Encrypt:

sudo apt install certbot python3-certbot-apache

Next, use Certbot to obtain and install an SSL certificate for your Redmine:

sudo certbot --apache

Certbot will prompt you to select the domain for which you want to obtain a certificate. Choose your Redmine domain and follow the prompts to complete the certificate installation.

Certbot provides automatic renewal of SSL certificates, ensuring that your PrestaShop store remains secure. The renewal process is typically handled by a systemd timer, which runs twice a day. You can manually test the certificate renewal process by running:

sudo certbot renew --dry-run

Step 7. Configure Firewall.

Configure a firewall to protect your Redmine server. UFW (Uncomplicated Firewall) is a user-friendly tool for this purpose:

sudo apt install ufw
sudo ufw allow OpenSSH
sudo ufw allow 'Apache Full'
sudo ufw enable

To check the status of UFW with the newly added rules, use:

sudo ufw status

Step 8. Accessing Redmine Web UI.

Access your Redmine instance by navigating to https://yourdomain. You should be able to log in and start using Redmine securely.
