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.

Prerequisites
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 the Redmine project management web app on a CentOS 7 server.
Install Redmine on CentOS 7
Step 1. First let’s start by ensuring your system is up-to-date.
yum clean all yum -y install epel-release yum -y update
Step 2. Installing all dependencies.
Install all dependencies that are required by Redmine:
yum install zlib-devel curl-devel openssl-devel httpd-devel apr-devel apr-util-devel mysql-devel ftp wget ImageMagick-devel gcc-c++ patch readline readline-devel zlib libyaml-devel libffi-devel make bzip2 autoconf automake libtool bison iconv-devel subversion
Step 3. Installing Ruby and RVM.
Redmin requires Ruby. So, first you’ll want to install Ruby Version Manager which allows managing of multiple ruby environments:
gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 curl -L https://get.rvm.io | bash -s stable --ruby=2.2.5
Now we have to add it the .bashrc file so it can be automatically reload and to add it to the .bashrc file run this:
echo '[[ -s "/usr/local/rvm/scripts/rvm" ]] && source "/usr/local/rvm/scripts/rvm"' >> ~/.bashrc
Reload the .bashrc file using this command:
source ~/.bashrc
Now run following command as shown below to check Ruby and RVM version:
ruby -v rvm -v
Step 4. Installing MySQL server.
MySQL needs to be configured so that Redmine can store data, so we will install MySQL server:
rpm -Uvh https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm yum repolist yum install mysql-server
Now start the mysqld service using systemctl command as shown below:
systemctl start mysqld
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 5. Installing Passenger and Nginx.
Passenger is an application server that runs your web application then communicates with the web server. We will install it and integrate it with Nginx:
gem install passenger --no-ri --no-rdoc passenger-install-nginx-module
You will be asked for some information, and then it will install Nginx. The default installation directory is /opt/nginx. Of course, you can change it. In it, edit conf/nginx.conf.
On line 23, paste the following content:
include vhost/*.conf;
Save and close the file. Next, create a vhost directory for Virtual Host configuration files:
mkdir -p /opt/nginx/conf/vhost
ost
In this directory, create a redmine.conf file. The paste the following into that file:
server {
listen 80;
server_name yourdomain.com;
root /var/www/html/redmine/public;
passenger_enabled on;
client_max_body_size 10m; # Max attachemnt size
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
Restart the web server for the changes to take effect:
systemctl restart nginx systemctl enable nginx
Step 6. Installing Redmine.
First, download the latest version of Redmine, at the moment of writing this article it is version 3.4:
cd /var/www/ svn co http://svn.redmine.org/redmine/branches/3.4-stable redmine
Next, change the current working directory and the example configuration files:
cd redmine cp config/configuration.yml.example config/configuration.yml cp config/database.yml.example config/database.yml
Make the following changes to the database.yml file:
nano config/database.yml
Add following content:
production: adapter: mysql2 database: redmine host: localhost username: redmine password: PASSWORD encoding: utf8
Run following commands to change the owner to user and group nobody:
mkdir -p tmp tmp/pdf public/plugin_assetssud chown -R nobody:nobody files log tmp public/plugin_assetssudo chmod -R 775 files log tmp public/plugin_assets
Install the bundler and gem dependencies for redmine:
gem install bundlerbundle install --without development test
Generate the secret token using the following command:
bundle exec rake generate_secret_token RAILS_ENV=production bundle exec rake db:migrate RAILS_ENV=production bundle exec rake redmine:load_default_data
Finally, Restart the web server for the changes to take effect:
systemctl restart nginx
Step 7. Accessing Redmine.
Redmine will be available on HTTP 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.
