Install Apache HTTP Server on Ubuntu 22.04

Install Apache web server and Apache modules for the Passenger, lightweight web server for Ruby.

apt install apache2 libapache2-mod-passenger

Start and enable Apache to run on system boot.

systemctl enable --now apache2

Install Ruby interpreter

Redmine version 5.1 supports upto Ruby 3.2 as of this post update!

This falls within the supported versions.

Create Redmine System User

Create a Redmine system user that can be used to install Redmine Ruby dependencies via bundler command. Set its home directory to /opt/redmine as this is where we will install Redmine app.

useradd -r -m -d /opt/redmine -s /usr/bin/bash redmine

MySQL is started and enabled to run on boot upon installation.

systemctl status  mysql

If not already started, run the command below to start it;

systemctl enable --now mysql

Run initial MySQL database secure script to remove default databases, test tables, disable remote root login,


Create Redmine Database and Database User

Once MySQL is installed, login as root user and create Redmine database and database user.

Replace the names of the database and the database user accordingly.

mysql -u root -p
create database redminedb;
create user redmineuser@localhost identified by 'P@ssW0rD';
grant all on redminedb.* to redmineuser@localhost;

Reload privilege tables and exit the database.

flush privileges;

Download and Install Redmine

Navigate Redmine releases page and grab Redmine tarball for the current stable release version.

You can simply download and extract the Redmine tarball to the Redmine install directory, /opt/redmine.

curl -s$VER.tar.gz | \
sudo -u redmine tar xz -C /opt/redmine/ --strip-components=1

Configuring Redmine on Ubuntu 22.04

Once you have installed Redmine under the /opt/redmine directory, you can now proceed to configure it.

Create Redmin Configuration Files

Create Redmine configuration file by renaming the sample configuration files as shown below;

su - redmine
cp /opt/redmine/config/configuration.yml{.example,}
cp /opt/redmine/public/dispatch.fcgi{.example,}
cp /opt/redmine/config/database.yml{.example,}

Configure Redmine Database Settings

Open the created Redmine database configuration setting and set the Redmine database connection details for MySQL.

vim /opt/redmine/config/database.yml
  adapter: mysql2
  database: redminedb
  host: localhost
  username: redmineuser
  password: "P@ssW0rD"
  # Use "utf8" instead of "utfmb4" for MySQL prior to 5.7.7
  encoding: utf8mb4

Save and exit the file.

Install Redmine Ruby Dependencies

Logout as redmine user by running the exit.


 As privileged user, navigate to Redmine install directory and install the Ruby dependencies.

cd /opt/redmine

Install Bundler for managing gem dependencies.

sudo gem install bundler

Install the Base64 module.

sudo gem install base64

Next, install the required gems dependencies as redmine user.

su - redmine
bundle config set --local path 'vendor/bundle'
bundle install

Also update the gems;

bundle update

Install updated io-wait and strscan gems;

gem install io-wait strscan webrick --user-install

Generate Secret Session Token

To prevent tempering of the cookies that stores session data, you need to generate a random secret key that Rails uses to encode them.

bundle exec rake generate_secret_token

Create Database Schema Objects

Create Rails database structure by running the command below;

Ensure you set the correct database credentials above,

RAILS_ENV=production bundle exec rake db:migrate

Once the database migration is done, insert default configuration data into the database by executing;

RAILS_ENV=production REDMINE_LANG=en bundle exec rake redmine:load_default_data

You can safely ignore the Ruby warnings.

Configure FileSystem Permissions

Ensure that the following directories are available on Redmine directory, /opt/redmine.

  • tmp and tmp/pdf
  • public and public/plugin_assets
  • log
  • files

If they do not exist, simply create them and ensure that they are owned by the user used to run Redmine.

for i in tmp tmp/pdf public/plugin_assets; do [ -d $i ] || mkdir -p $i; done
chown -R redmine:redmine files log tmp public/plugin_assets
chmod -R 755 /opt/redmine

Testing Redmine Installation

The setup of Redmine on Ubuntu 22.04 is now done.

Redmine listens on TCP port 3000 by default. Hence, before running the tests, open port 3000/tcp on firewall if it is running.

redmine@ubuntu22:~$ exit
sudo ufw allow 3000/tcp

You can now test Redmine using WEBrick by executing the command below;

su - redmine

Add webrick to Gemfile;

echo 'gem "webrick"' >> Gemfile

Install webrick gem and test the installation;

bundle install
bundle exec rails server -u webrick -e production

Sample output;

=> Booting WEBrick
=> Rails application starting in production
=> Run `bin/rails server --help` for more startup options
[2024-03-03 11:59:32] INFO  WEBrick 1.8.1
[2024-03-03 11:59:32] INFO  ruby 3.0.2 (2021-07-07) [x86_64-linux-gnu]
[2024-03-03 11:59:32] INFO  WEBrick::HTTPServer#start: pid=14164 port=3000

Navigate to the browser and enter the address, http://server-IP-or-Hostname:3000. Replace the server-IP-or-Hostname accordingly.

If all is well, you should land on Redmine web user interface.

Install Redmine on Ubuntu 22.04

Configure Apache for Redmine on Ubuntu 22.04

Now that you have confirmed that Redmine is working as expected, proceed to configure Apache to server Redmine.

Press CTRL+C to stop Redmine in foreground and exit redmine user account.


next, create Redmine Apache VirtualHost configuration file.

cat > /etc/apache2/sites-available/redmine.conf << 'EOL'
Listen 3000
<VirtualHost *:3000>
	RailsEnv production
	DocumentRoot /opt/redmine/public

	<Directory "/opt/redmine/public">
	        Allow from all
	        Require all granted

	ErrorLog ${APACHE_LOG_DIR}/redmine_error.log
        CustomLog ${APACHE_LOG_DIR}/redmine_access.log combined

Ensure the value of the ServerName, the domain, is resolvable! You can use hosts file to define the IP address if you dont have a DNS server.

Disable the default site configuration.

a2dissite 000-default.conf

Check Apache configuration for errors.

apachectl configtest
Syntax OK

Ensure that Passenger module is loaded;

apache2ctl -M | grep -i passenger
passenger_module (shared)

If not enabled, run the command below to enable it.

a2enmod passenger

Enable Redmine site.

sudo a2ensite redmine

Reload Apache

sudo systemctl restart apache2

Check to ensure that Redmine is now listening on port 3000.

sudo lsof -i :3000
apache2 7630     root    6u  IPv6  48985      0t0  TCP *:3000 (LISTEN)
apache2 7645 www-data    6u  IPv6  48985      0t0  TCP *:3000 (LISTEN)
apache2 7646 www-data    6u  IPv6  48985      0t0  TCP *:3000 (LISTEN)

Access Redmine on Browser

Next, you can now access and sign in to Redmine on browser using the address http://server-IP-or-domain-address:3000.

Click Sign in at the top right corner.

Default credentials: admin:admin.

Install Redmine on Ubuntu 22.04

  1. Hello:
    I am so lucky to see your post.
    You are posting in 2022.
    Today, I installed according to your article.
    It is impossible to succeed.
    I guess it should be caused by dependent components.
    I wonder if you have time to try again and correct this post?
    Thank you very much!

  2. I really like your instructions for installing Redmine. This instruction worked great until I had to install Ubuntu 22.04 and Redmine from scratch. I assume that in the new installation Bundler uses updated gems, which leads to the inability to display the Redmine page. Moreover, Wibrik and PUMA successfully display the site. Most likely the problem is with mod_passenger (((I would be very grateful if you corrected the algorithm so that it would work again.

    • Thank you for catching that, Evgen. We just changed the database from MariaDB to MySQL 8.x. All good now.
