Redmine installation on Ubuntu 20.04

This manual will help you to install a fresh Redmine version from sources to the Ubuntu server.

1. Installing RVM (Ruby Version Manager)

$ sudo apt-get install curl mysql-server libmysqlclient-dev git-core subversion imagemagick libmagickwand-dev libcurl4-openssl-dev pgp
$ sudo apt-get update
Install RVM as non-root
$ gpg --keyserver hkp:// --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
$ curl -sSL | bash
Now, you should load the RVM
$ sudo su
# source /etc/profile.d/
# echo '[[ -s "/etc/profile.d/" ]] && source "/etc/profile.d/"' >> ~/.bashrc
and install Ruby
# rvm get head
# rvm install ruby-3.1.2

2. Installing Phusion Passenger and Nginx

# sudo apt-get install libcurl4-gnutls-dev
# gem install passenger --no-document
# passenger-install-nginx-module

Configuring Nginx

# systemctl stop nginx
# curl > /lib/systemd/system/nginx.service
# systemctl daemon-reload
# systemctl enable nginx
# nano /opt/nginx/conf/nginx.conf

Replace server section for port 80

server {
  listen  80;
  server_name [your_server_domain_name] #;
  root /var/data/redmine/public;
  passenger_enabled on;
  client_max_body_size      10m; # Max attachemnt size

Restart Nginx

# systemctl stop nginx
# systemctl start nginx

3. Installing Redmine

# mkdir /var/data
# cd /var/data/
# svn co redmine
# cd /var/data/redmine

Database configuration

# nano config/database.yml

Add following lines

  adapter: mysql2
  database: redmine
  host: localhost
  username: redmine
  password: redmine
  encoding: utf8

  adapter: mysql2
  database: redmine 
  host: localhost
  username: redmine
  password: redmine
  encoding: utf8

4. Plugins installation

Unarchive plugins to /plugins/ folder and execute

# cd /var/data/redmine
# gem install bundler --no-document
# bundle install

5. Configuring redmine

Setup redmine folder permissions

# cd /var/data/redmine
# mkdir public/plugin_assets
# chown -R www-data:www-data files log tmp public/plugin_assets
# chmod -R 755 files log tmp public/plugin_assets

Create database

# mysql -u root -p

Execute following lines to MySQL

CREATE DATABASE redmine character SET utf8;
CREATE user 'redmine'@'localhost' IDENTIFIED BY 'redmine';
GRANT ALL privileges ON redmine.* TO 'redmine'@'localhost';

Migrate database

# cd /var/data/redmine
# bundle exec rake db:migrate
# bundle exec rake redmine:plugins

Generate session store

# bundle exec rake generate_secret_token 

Default demo data

If you want to, you can download some default data (statuses, workflows, trackers) to be able to start to work with your Redmine right after the first login. To do this, run the following command:

# bundle exec rake redmine:load_default_data RAILS_ENV=production

It will ask you about the preferable language and then download some default package of data to your Redmine.

Start web server

# service nginx start

Restart Redmine

# touch /var/data/redmine/tmp/restart.txt
