These instructions provide a recipe for building your own all-in-one Avalon system from scratch on CentOS or Red Hat Enterprise Linux version 7.x.  Please note that while an all-in-one installation as outlined here is certainly suitable for testing and demos, a single, all-in-one, server may not be suitable for production environments.

Ready the Installation Environment

Storage requirement

Avalon and components need about 20GB of disk space to install.

Open ports requirement

The Avalon Media System requires several ports to be open to client browsers.

Here are the port settings that will need to be configured:

These instructions provide a recipe for building your own all-in-one Avalon system from scratch on CentOS or Red Hat Enterprise Linux version 7.x.  Please note that while an all-in-one, single machine installation as outlined here is certainly suitable for testing and demos, production environments are typically implemented across multiple servers running the main components of the application.

Ready the Installation Environment

Storage requirement

Avalon and components need about 20GB of disk space to install.

Open ports requirement

The Avalon Media System requires several ports to be open to client browsers.

Here are the port settings that will need to be configured:

...

mysql
mariadb> create database fcrepo CHARACTER SET utf8 COLLATE utf8_general_ci;
mariadb> create user 'fcrepo'@'localhost' identified by '<fcrepo_password>';
mariadb> grant all privileges on fcrepo.* to 'fcrepo'@'localhost';

mariadb> create database rails rails CHARACTER SET utf8 COLLATE utf8_general_ci;
mariadb> create user 'rails'@'localhost' identified by '<rails_pasword>';
mariadb> grant all privileges on rails.* to 'rails'@'localhost';

mariadb> flush privileges;

Try it out on your local machine and on another machine. If you can't reach the app from another machine, your iptables1957955315 might need to be changed to allow access. If Fedora is not up, check the tomcat logs in /var/log/tomcat/. Catalina.out and localhost.<date>.log usually provide the best information.

Replace database.yml with the correct values for your production environment. Note that the pool setting should be equal or exceed the number of concurrent jobs in Sidekiq.

production:
  adapter: mysql2
  host: localhost
  database: rails
  username: rails
  password: rails
  pool: 520
  timeout: 5000

Install the mysql2 adapter 

...

# as root
yum install redis
systemctl start redis

Install Sidekiq

# as root
wget https://raw.githubusercontent.com/mperham/sidekiq/master/examples/systemd/sidekiq.service -O /lib/systemd/system/sidekiq.service

Edit the following lines in sidekiq.service 

WorkingDirectory=/var/www/avalon
ExecStart=/bin/bash -lc '/home/avalon/.rvm/gems/ruby-2.5.5/bin/bundle exec sidekiq -e production'
User=avalon
Group=avalon

# as root
systemctl start sidekiq

...

 start redis

Install Sidekiq

# as root
wget https://raw.githubusercontent.com/mperham/sidekiq/main/examples/systemd/sidekiq.service -O /lib/systemd/system/sidekiq.service

Edit the following lines in sidekiq.service

# as root
systemctl start sidekiq

Sidekiq logs to STDOUT. 

Additional Configurations

...

Avalon comes with Persona by default but it can be configured to work with other authentication strategies by using the appropriate omniauth gems. The following example is applicable to Indiana University CAS, it may need some adjustments in order to work with other CAS implementation.
Add to Gemfile

gem 'net-ldap'
gem 'omniauth-cas', :git => "https://github.com/cjcolvar/omniauth-cas.git"

Install new gems

bundle install

Add to config/initializers/my-ldap.rb

...

other CAS implementation.

Add to Gemfile

gem 'net-ldap'
gem 'omniauth-cas', :git => "https://github.com/cjcolvar/omniauth-cas.git"

Install new gems

bundle install

Add to config/initializers/my-ldap.rb

module Avalon
      GROUPMY_GUEST_LDAP = Net::LDAP.new
      GROUP_LDAP.host = "ads.myuni.edu"
      GROUP_LDAP.authenticate 'cn=******,ou=Accounts,dc=ads,dc=myuni,dc=edu', '******'LDAP.new
      GROUPMY_GUEST_LDAP_TREE.host = "dc=ads,dc=myuni,dc=edu"
end

Add config/initializers/user_auth_cas.rb

require 'net/ldap'
