Redmine is a project management web app that allows users to manage projects flexibly while offering robust monitoring tools and a broad library of plug-ins. This free and open source solution offers a substitute for paid job management tools and contains support for wikis, forums, calendars, and information visualization programs.

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 through the step by step installation Wine on an Ubuntu 18.04 (Bionic Beaver) server.

Install Redmine on Ubuntu 18.04 LTS

Step 1. First, make sure that all your system packages are up-to-date

sudo apt update
sudo apt upgrade
sudo apt install build-essential libmysqlclient-dev imagemagick libmagickwand-dev
[php]

Step 2. Installing MySQL server.

[php]
MySQL needs to be configured so that Redmine can store data, so we will install MySQL server:
apt-get install mysql-server mysql-client

By default, MySQL is not hardened. You can secure MySQL using the mysql_secure_installation script. You should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- 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

Next we will need to log in to the MySQL console and create a database for the Redmine. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MySQL root password and hit Enter. Once you are logged in to your database server you need to create a database for Redmine installation:

CREATE DATABASE redmin
GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost' IDENTIFIED BY 'PASSWORD';
FLUSH PRIVILEGES;
\q

Step 3. Installing Ruby.

Install Ruby using following command:

sudo apt install ruby-full

Step 4. Installing Passenger and Nginx.

Passenger is a fast and lightweight web application server for Ruby, Node.js and Python that can be integrated with Apache and Nginx. We will install Passenger as an Nginx module:

sudo apt install dirmngr gnupg apt-transport-https ca-certificates

Next, import the repository GPG key and enable the Phusionpassenger repository:

sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 561F9B9CAC40B2F7
sudo add-apt-repository 'deb https://oss-binaries.phusionpassenger.com/apt/passenger bionic main'

Once the repository is enabled, update the packages list and install the Passenger Nginx module with:

sudo apt update
sudo apt install libnginx-mod-http-passenger

Step 5. Installing Redmine on Ubuntu 18.04.

First, download the latest version of Redmine, at the moment of writing this article it is version 4:

sudo curl -L http://www.redmine.org/releases/redmine-4.0.1.tar.gz -o /tmp/redmine.tar.gz
sudo tar zxf /tmp/redmine.tar.gz
sudo mv /tmp/redmine-4.0.1 /opt/redmine

Make the following changes to the database.yml file:

sudo cp /opt/redmine/config/database.yml.example /opt/redmine/config/database.yml
sudo nano /opt/redmine/config/database.yml

Add following content:

production:
  adapter: mysql2
  database: redmine
  host: localhost
  username: redmine
  password: "change-with-strong-password"
  encoding: utf8

Install the Ruby dependencies and migrate the database:

cd /opt/redmine/
sudo gem install bundler --no-rdoc --no-ri
sudo bundle install --without development test postgresql sqlite

Generate the secret token using the following command:

cd /opt/redmine/
sudo bundle exec rake generate_secret_token
sudo RAILS_ENV=production bundle exec rake db:migrate

Then, Set the correct permissions by issuing following chown command:

sudo chown -R www-data: /opt/redmine/

Open your text editor and create the following Nginx vhost file:

sudo nano /etc/nginx/sites-available/example.com

# Redirect HTTP -> HTTPS
server {
    listen 80;
    server_name www.example.com example.com;

    include snippets/letsencrypt.conf;
    return 301 https://example.com$request_uri;
}

# Redirect WWW -> NON WWW
server {
    listen 443 ssl http2;
    server_name www.example.com;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/example.com/chain.pem;
    include snippets/ssl.conf;

    return 301 https://example.com$request_uri;
}

server {
    listen 443 ssl http2;
    server_name example.com;

    root /opt/redmine/public;

    # SSL parameters
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/example.com/chain.pem;
    include snippets/ssl.conf;
    include snippets/letsencrypt.conf;

    # log files
    access_log /var/log/nginx/example.com.access.log;
    error_log /var/log/nginx/example.com.error.log;

    passenger_enabled on;
    passenger_min_instances 1;
    client_max_body_size 10m;
}

Enable the server block by creating a symbolic link to the sites-enabled directory:

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

Restart the web server for the changes to take effect:

sudo systemctl restart nginx

Step 6. Accessing Redmine.

Redmine will be available on HTTPInstall Redmine on Ubuntu 18 port 80 by default. Open your favorite browser and navigate to http://mydomain.com and complete the required the steps to finish the installation using the default credentials (admin/admin). If you are using a firewall, please open port 80 to enable access to the control panel.
