Introducing to Redmine

Install Redmine on Ubuntu 20.04

The application requires a web server and a database manager like MariaDB. So, we have that for this post, we are going to install Apache and MariaDB.

Install Apache and MariaDB on Ubuntu 20.04

First we have to install Apache and MariaDB because they are required components of the system. So open up a terminal or via SSH and run.

apt update
apt upgrade

These commands as root user.

Now install Apache, the passenger module and MariaDB.

apt install apache2 libapache2-mod-passenger mariadb-server mariadb-client

When the installation is finished, you will be able to use MariaDB to set a root password thanks to the mysql_secure_installation script.


When you run it, it will ask for a password that we have to leave blank because there is not one defined. Then, you will be able to define yours.

Thereafter, you will be asked some configuration questions

Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

Answer Y to all and then the script will terminate. Then we are ready to go.

Now go to the MariaDB console to create the new database and user for Redmine.

mysql -u root -p

Now create the database


Then the user

GRANT ALL PRIVILEGES ON redminedb.* TO 'redmine'@'localhost' IDENTIFIED BY 'pass';

Remember that you can assign another name and password.

Refresh permissions and exit the console.


Install Redmine on Ubuntu 20.04

With the system ready, we can start installing Redmine on the system along with the MySQL or MariaDB plugin. So, here’s how to do it:

apt install redmine redmine-mysql

During the execution of the command, you will notice that you will be asked a question about configuring the database. We will have to choose YES.

In the next screens you will have to define the password which should be the same as we did before for the user. Then the installation will continue.

As Redmine is made with Ruby, it is necessary to install bundler on the system.

gem install bundler

Sample Output

Fetching bundler-2.3.10.gem
Successfully installed bundler-2.3.10
Parsing documentation for bundler-2.3.10
Installing ri documentation for bundler-2.3.10
Done installing documentation for bundler after 0 seconds
1 gem installed

The next step is to edit the passenger module configuration file.

nano /etc/apache2/mods-available/passenger.conf

And replace the content with the following

<IfModule mod_passenger.c>
PassengerDefaultUser www-data
PassengerRoot /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini
PassengerDefaultRuby /usr/bin/ruby

Then make a symbolic link from the Redmine folder on the system to the Apache directory.

ln -s /usr/share/redmine/public /var/www/html/redmine

Then create a file called Gemfile.lock in /usr/share/redmine/.

chown www-data:www-data /usr/share/redmine/Gemfile.lock

Set the proper permission to the folder.

chown -R www-data:www-data /var/www/html/redmine

Then, create a new Apache VirtualHost for Redmine.

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

And add the following

<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot /var/www/html/redmine
<Directory /var/www/html/redmine>
RailsBaseURI /redmine
PassengerResolveSymlinksInDocumentRoot on
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

Replace ServerName with your domain.

Then enable the new configuration and restart Apache.

a2ensite redmine.conf
systemctl restart apache2

Access the Redmine web interface

The next step is to open a web browser and visit your domain, so you can see the Redmine home page.

Redmine first screen
