How to Install and Configure Redmine on Ubuntu 16.04

What is Redmine?

Redmine is a project management web app that allows users to manage projects flexibly while offering robust tracking tools and an extensive library of plug-ins. This free and open source solution offers an alternative to paid project management tools and includes support for wikis, forums, calendars, and data visualization tools.

This guide will show you how to install and set up Redmine on Ubuntu 16.04 through the Passenger application server connected to NGINX.

Before You Begin

Install Dependencies

sudo apt install build-essential mysql-server ruby ruby-dev libmysqlclient-dev imagemagick libmagickwand-dev

Configure MySQL

MySQL needs to be configured so that Redmine can store data. You can log in to the root account of your database using the password that you set when you installed mysql-server.

 mysql -u root -p

1. After logging in, create a new database and database user:

   1 2 3 4 5

   CREATE DATABASE redmine; CREATE USER 'redmine'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost'; FLUSH PRIVILEGES; quit;

Install Ruby

Redmine requires Ruby to run. Use the Ruby Version Manager (RVM) to install Ruby 2.2.3.

1. Curl the latest version of RVM.

   gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
   curl -sSL https://get.rvm.io | bash -s stable
   source ~/.rvm/scripts/rvm

2. Users of RVM must be in the rvm group. Create this group, add a user, log out, and log back in:

   sudo groupadd rvm
   sudo usermod -a -G rvm username
   exit

3. Check the requirements for the install, and install Ruby (version 2.2.3):

   rvm requirements
   rvm install 2.2.3
   rvm use 2.2.3 --default

Install Passenger and NGINX

Passenger is an application server that runs your web application then communicates with the web server. The project has well-written documentation on installing Passenger and NGINX on Ubuntu 16.04 with an apt repository.

1. Install the Passenger PGP key and HTTPS support for the package manager:

   sudo apt install -y dirmngr gnupg
   sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
   sudo apt install -y apt-transport-https ca-certificates
   

2. Add the Passenger APT repository:

   sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger xenial main > /etc/apt/sources.list.d/passenger.list'
   sudo apt update
   

3. Install Passenger and NGINX

   sudo apt install -y nginx-extras passenger
   

Configure NGINX

Passenger has now installed NGINX with Passenger compiled in. You have to configure NGINX to make sure it uses Passenger correctly:

1. Uncomment the include /etc/nginx/passenger.conf; line in /etc/nginx/nginx.conf. Edit your config file to resemble the one below:

   File: /etc/nginx/nginx.conf

   1 2 3 4 5 6 7 8 9 10 11 12 13

   ## # Phusion Passenger config ## # Uncomment it if you installed passenger or passenger-enterprise ## include /etc/nginx/passenger.conf; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf;

2. Copy the default nginx site configuration file. The working configuration file in this guide will be /etc/nginx/sites-available/default:

   cp /etc/nginx/sites-available/default /etc/nginx/sites-available/default.orig
   

3. Change the root directory for the website, and add additional Passenger configurations. To do this, add these lines to the server{} block of the file:

   File: /etc/nginx/sites-available/default

   1 2 3

   root /data/redmine/redmine/public; passenger_enabled on; client_max_body_size 10m;

4. In the same file, comment out the #location section:

   File: /etc/ningx/site-available/default

   1 2 3 4 5

   #location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. #try_files $uri $uri/ =404; #}

5. Change the permissions for /var/www:

   sudo mkdir /var/www
   sudo chown -R www-data /var/www
   

6. Restart nginx:

   sudo systemctl restart nginx
   

7. Validate the installation of Passenger and NGINX:

   sudo /usr/bin/passenger-config validate-install
   

   Press enter when the first option is selected:

    If the menu doesn't display correctly, press '!'
   
   ‣ ⬢  Passenger itself
     ⬡  Apache
   
     -------------------------------------------------------------------------
   
   * Checking whether this Passenger install is in PATH... ✓
   * Checking whether there are no other Passenger installations... ✓
   Everything looks good. :-()

8. Finally, check if NGINX has started the Passenger core process:

   sudo /usr/sbin/passenger-memory-stats
   

   If Passenger was installed with NGINX correctly, your output should resemble:

   --------- NGINX processes ----------
   PID   PPID  VMSize    Private  Name
   ------------------------------------
   6399  1     174.9 MB  0.6 MB   nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
   6404  6399  174.9 MB  0.7 MB   nginx: worker process
   ### Processes: 2
   ### Total private dirty RSS: 1.23 MB
   
   
   ---- Passenger processes -----
   PID   VMSize    Private  Name
   ------------------------------
   6379  441.3 MB  1.2 MB   Passenger watchdog
   6382  660.4 MB  2.9 MB   Passenger core
   6388  449.5 MB  1.4 MB   Passenger ust-router
   ### Processes: 3

Install Redmine

1. Create a redmine user and add the new user to the sudo group:

    sudo adduser --system --shell /bin/bash --gecos 'Redmine Administrator' --group --home /data/redmine redmine; sudo usermod -a -G rvm redmine
    sudo adduser redmine sudo
   

2. Log in as the redmine user:

   su -
   passwd redmine
   su redmine
   cd
   

3. Download the Redmine tarball as the new user. Extract it and rename the directory to redmine for convenience:

   wget https://www.redmine.org/releases/redmine-3.4.4.tar.gz
   tar -zxvf redmine-3.4.4.tar.gz
   mv redmine-3.4.4 redmine
   

4. Add the database information created earlier to Redmine’s config file. Only complete the section marked “Production,” as you will not be using the development or test environments.

    cd redmine
    cp -pR config/database.yml.example config/database.yml
    emacs config/database.yml
   

5. In the redmine directory, install the Ruby dependencies:

    sudo gem install bundler
    sudo bundle install --without development test
   

6. After the installation finishes, you need to use Rake to start the server:

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

7. Restart NGINX, and navigate to your server’s IP address and you will be greeted by the Redmine application:

    sudo systemctl restart nginx
   

   

Redmine

The default login and password for Redmine are:

 Login: admin
 Password: admin

After logging in for the first time, you will be prompted to change your credentials. Replace them with something secure.

Install a Plug-in

Redmine is built to be used with plug-ins. Plug-ins are installed to redmine/plugins. This section will demonstrate installing a plug-in by installing scrum2b , a plug-in for managing a Scrum/Agile workflow.

If not installed, install git or download the plug-in directly through the Github website:

sudo apt install git

1. Move to redmine/plugins and clone the plug-in:

    cd plugins
    git clone https://github.com/scrum2b/scrum2b
   

2. Use Bundle to install the plug-in, then restart NGINX:

    bundle install
    sudo systemctl restart nginx
   

3. Navigate to Redmine in your browser. Log in, click admin then click plugins

Next Steps

You now have a working Redmine setup on your Linode. If you plan on using it in production, explore plug-ins that will be useful for your team. Take a look at some of the guides below to customize Redmine for your team.
