Efficiently Manage Projects with Redmine on CentOS 8

Installing and Configuring Redmine on CentOS 8

In today’s digital age, project management is an essential part of any business, regardless of size. And to efficiently manage a project, you need effective tools that help you delegate, track and monitor tasks, communicate status updates, and ultimately, deliver the project on time.

This is where Redmine comes in handy. Redmine is a web-based project management tool that offers features such as project wiki, time tracking, and issue tracking.

It allows team members to collaborate in real-time, which increases productivity and improves communication. If you plan to use Redmine as your project management tool, this guide will help you install and configure it on your CentOS 8 system.

Prerequisites

Before installing Redmine, there are some prerequisites that you need to meet. Ensure that you have:

– A CentOS 8 system with a minimal installation

– A user with sudo privileges

– A functional internet connection

– MariaDB server

– Ruby

– Apache web server

– Passenger web application server

Creating a MySQL database

Redmine uses a MySQL database to store its data. Therefore, the first step is to create a database and a user with appropriate permissions.

Use the following commands to create a database and a user and grant them access to the database:

1. Log in to your MariaDB server using the following command:

mysql -u root -p

2. Create a database, for example, “redmine_db” using the following command:

CREATE DATABASE redmine_db DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

3.

Create a MySQL user and set the password. Replace “username” with your desired username and “password” with your desired password:

CREATE USER ‘username’@’localhost’ IDENTIFIED BY ‘password’;

4.

Grant the user all the privileges on the database that you just created:

GRANT ALL PRIVILEGES ON redmine_db.* TO ‘username’@’localhost’ IDENTIFIED BY ‘password’;

Installing Passenger, Apache, and Ruby

To install Passenger, Apache, and Ruby, you need to enable the EPEL repository, install the required packages using yum, and configure the firewall to allow HTTP and HTTPS traffic. Use the following commands to do this:

1.

Enable the EPEL repository:

sudo dnf install epel-release

2. Install the required packages:

sudo dnf -y install redhat-rpm-config httpd-devel gcc-c++ patch readline readline-devel zlib zlib-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison sqlite-devel nodejs mariadb-devel

3.

Install passenger and nginx:

sudo dnf -y install passenger

4. Add passenger to Apache:

sudo passenger-install-apache2-module

5. Start Apache:

sudo systemctl start httpd

Creating a New System User

For security reasons, it is best practice to create a new system user and group for Redmine and assign the appropriate permissions. Use the following commands to create a new user and group and assign the appropriate permissions:

1.

Create a new group using the following command:

sudo groupadd redmine

2. Create a new user and place them in the redmine group:

sudo useradd -g redmine -d /opt/redmine -s /bin/bash redmine

3.

Assign the appropriate permissions:

sudo chown -R redmine:redmine /opt/redmine

Installing Redmine

Finally, it’s time to install Redmine. Use the following commands to download and install Redmine:

1.

Download and extract the package:

cd /opt/redmine

sudo wget https://www.redmine.org/releases/redmine-4.2.1.tar.gz

sudo tar zxf redmine-4.2.1.tar.gz

2. Install the required dependencies:

cd redmine-4.2.1

sudo yum -y install ImageMagick-devel gcc mysql-devel patch openssl libyaml-devel libffi-devel libicu-devel zlib-devel

3. Configure the database:

cp config/database.yml.example config/database.yml

sudo vi config/database.yml

4.

Generate a session store secret key:

cd /opt/redmine/redmine-4.2.1

sudo bundle install –without development test

RAILS_ENV=production rake generate_secret_token

5. Migrate the database:

sudo RAILS_ENV=production rake db:migrate

6.

Start the application server:

sudo passenger-install-apache2-module

Configuring Apache

Now that you have installed and configured Redmine, it is necessary to configure Apache to run the application. Follow these steps to configure Apache:

1.

Configure the vhost file:

sudo vi /etc/httpd/conf.d/redmine.conf

ServerName example.com

DocumentRoot /opt/redmine/redmine-4.2.1/public

PassengerRuby /usr/bin/ruby

PassengerAppEnv production

Require all granted

Options -MultiViews

AllowOverride All

RewriteEngine on

RewriteCond %{HTTPS} off

RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

2. Restart Apache:

sudo systemctl restart httpd

Configuring Apache with SSL

It is highly recommended to configure Apache with SSL to secure the communication between the client and server. Here’s how to do it:

1.

Install the Certbot client:

sudo dnf install certbot python3-certbot-apache

2. Obtain an SSL certificate from Let’s Encrypt:

sudo certbot –apache -d example.com

3.

Configure the firewall:

sudo firewall-cmd –permanent –add-service=http

sudo firewall-cmd –permanent –add-service=https

sudo firewall-cmd –reload
