Install Redmine on Fedora Linux

Last Updated:

This guide will take you through how to install Redmine on Fedora Linux. Redmine is a cross-platform as well as cross-database flexible project management web application and we are using Fedora 39 specifically on this blog post.

Redmine has quite a number of features that are described on Redmine features page.

Installing Redmine on Fedora Linux

Create Redmine System User

In this guide, we will install Redmine on /opt/redmine directory and run it as non-privileged redmine system user.

As such, create a redmine system user (or any other non-privileged system user that Redmine will run as for that case) and assign the /opt/redmine as its home directory.

useradd -r -m -d /opt/redmine redmine

Consult man useradd to learn what the options used above means.

Install Apache HTTP Server

To install Apache HTTP server on Fedora Linux, simply execute;

dnf install httpd

Start and enable Apache HTTP server to run on system boot;

systemctl enable httpd --now

Next, since we will be using Apache as our HTTP server, add Apache to Redmine group.

usermod -aG redmine apache

Install MariaDB Database Backend

Redmine supports a number of database back-ends such as PostgreSQL, MySQL/MariaDB, MSSQL. In this demo, we are using MariaDB 10.x.

dnf install mariadb-server

run the command below to start and enable MariaDB server on system boot;

systemctl enable --now mariadb

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


Create Redmine Database and Database User

Once the database backend is installed, login and create the database and database user for Redmine. Replace the database name accordingly.

mysql -u root -p
create database redminedb;

Create and grant the user all privileges on the database created. Replace the database user and password accordingly.

grant all on redminedb.* to redmineadmin@localhost identified by 'P@ssWorD';

Reload privileges tables and quit.

flush privileges;

Download and Install Redmine

Install Required Dependencies

Begin by installing the dependencies required to build Redmine.

dnf install ruby-devel \
	rpm-build \
	wget \
	libxml2-devel \
	vim \
	make \
	openssl-devel \
	automake \
	libtool \
	ImageMagick \
	ImageMagick-devel \
	mariadb-devel \
	gcc \
	httpd-devel \
	libcurl-devel \
	gcc-c++ -y

Install Ruby on Fedora Linux

Redmine also requires Ruby interpreter which is installed automatically with the dependencies above.

Verify installed version.

ruby -v
ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]

Redmine version 5.1 supports upto Ruby 3.1 as of this post update! We used Ruby 3.2.2 and it seems to work!

Download and Install Redmine

In order to install the latest version of Redmine, navigate to the Download’s page and grab the latest 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

You should now have redmine files under /opt/redmine.

ls -alh /opt/redmine

Configure Redmine Database Connection Settings

First switch to Redmine’s user account.

su - redmine

Rename the sample Redmine configuration.

cp config/configuration.yml{.example,}

Rename the sample dispatch CGI configuration file under the public folder as shown below;

cp public/dispatch.fcgi{.example,}

Rename the sample the database configuration file.

cp config/database.yml{.example,}

Next, open the database configure file for editing and and configure it to set the Redmine database connection details.

vim config/database.yml

Replace the database name, database user and the password accordingly.

  adapter: mysql2
  database: redminedb
  host: localhost
  username: redmineadmin
  password: "P@ssWorD"
  # Use "utf8" instead of "utfmb4" for MySQL prior to 5.7.7
  encoding: utf8mb4

Save and exit the file.

Install Ruby Dependencies

Next, install required Ruby dependencies. Note that this step should be executed as Redmine user created above. If you are still logged in as Redmine user, proceed. Otherwise, switch to redmine user.

su - redmine

Install Bundler for managing gem dependencies.

gem install bundler

Once the bundler installation is done, you can now install required gems dependencies.

bundle config set --local path 'vendor/bundle'
bundle config set --local without 'development test'
bundle 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;

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

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 Fedora Linux is now done. You can test Redmine using WEBrick by executing the command below;

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
[2023-11-13 08:03:05] INFO  WEBrick 1.8.1
[2023-11-13 08:03:05] INFO  ruby 3.2.2 (2023-03-30) [x86_64-linux]
[2023-11-13 08:03:05] INFO  WEBrick::HTTPServer#start: pid=4022 port=3000

You can now access Redmine via the browser using the address, http://Server-IP:3000/.

Before that, open port 3000/tcp on firewalld. Run the commands below as privileged user.

firewall-cmd --add-port=3000/tcp --permanent
firewall-cmd --reload

Once the port is opened, navigate to the browser and access Redmine. You should see a welcome page.

redmine webrick

Click sign in at the top right corner and use the credentials:

  • Useradmin
  • Password: admin

To stop Redmine foreground run, just press CTRL+C.

Configure Apache for Redmine

Once you have confirmed that Redmine is working fine after the testing, you need to configure Apache HTTP server for Redmine.

Install Apache Passenger Module

Phusion Passenger is a web application server that can be used to server Redmine on production environments.

Therefore, switch to Redmine user created above to install the Phusion Passenger Apache module;

su - redmine
gem install passenger --no-document

Next, install Passenger Apache module. Replace the version of the Passenger accordingly.


Follow through the installation guide to install Phusion Passenger. When prompted to choose a language, select Ruby and press Enter.

Welcome to the Phusion Passenger Apache 2 module installer, v6.0.18.

Compiling and installing Apache 2 module...

You could as well install Phusion Passenger from the RPM repos but as of this writing, couldn’t find any repos providing it on Fedora 39.

Once the module compilation is done, you are provided with how configure the module on Apache,

Almost there!

Please edit your Apache configuration file, and add these lines:

   LoadModule passenger_module /opt/redmine/.local/share/gem/ruby/gems/passenger-6.0.18/buildout/apache2/
     PassengerRoot /opt/redmine/.local/share/gem/ruby/gems/passenger-6.0.18
     PassengerDefaultRuby /usr/bin/ruby

After you restart Apache, you are ready to deploy any number of web
applications on Apache, with a minimum amount of configuration!

Press ENTER when you are done editing.

Create Redmine Apache Configuration file

Before you can press Enter to complete the Module installation and setup, open a new login session as privileged user and create/update the Redmine Apache configuration file.

Create Apache virtual host configuration for Redmine with the following content and configure it to load the passenger modules. Replace the Server Name accordingly and ensure it is resolvable if using domain name. You can as well change the default port if you want.

vim /etc/httpd/conf.d/redmine.conf
Listen 3000
LoadModule passenger_module /opt/redmine/.local/share/gem/ruby/gems/passenger-6.0.18/buildout/apache2/
<IfModule mod_passenger.c>
  PassengerRoot /opt/redmine/.local/share/gem/ruby/gems/passenger-6.0.18
  PassengerDefaultRuby /usr/bin/ruby
<VirtualHost *:3000>
    DocumentRoot "/opt/redmine/public"

You need to sort your SELinux permissions.

Phusion Passenger when not installed from the repositories does not come with SELinux policy modules and thus may not work well with SELinux enabled.

To make this simple, just disable SELinux and reboot your system and then access Redmine again on browser.

setenforce 0
sed -i 's/=enforcing/=disabled/' /etc/selinux/config

Otherwise if you want to keep SELinux running, generate a custom SELinux module for Phusion Passenger for any denied entry in /var/log/audit/audit.log and install it. For example;

dnf install policycoreutils-python-utils
grep -i denied /var/log/audit/audit.log | grep -i Passenger | audit2allow -a -M passenger

This command generated a policy package that can be installed by running;

semodule -i passenger.pp

With SELinux issues fixed, login to Redmine using admin for both user and password.

You are prompted to reset the password. Do reset and proceed to login to Redmine web interface.

After login, reset the password and proceed to setup your Redmine profile on Fedora Linux.
