GitLab Unicorn web server is not running

I installed gilab using these instructions: gitlab.com

When gitlab start, I get a message in the console: The GitLab Unicorn web server is not running.

When I go to server, in the browser i get 502 error.

It is unicorn.stderr.log: link to plunker

This error can occur because of what?

NGINX config: link to plunker

gitlab.yml: link to plunker

The first line within your Unicorn logs highlights the problem:

/home/git/gitlab/vendor/bundle/ruby/2.1.0/gems/activerecord-4.2.6/lib/active_record/connection_adapters/connection_specification.rb:177:in `rescue in spec': Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). (Gem::LoadError)

You have specified that you're going to use MySQL within the config/database.yml file, but the Gem mysql2 doesn't appear to be installed. The mysql2 Gem contains the necessary libraries for interacting with your MySQL database.

The following command:

gem list

Will list the Gems that are currently installed, allowing you to verify whether mysql2 is amongst them.

This section of the installation document covers the installation of the necessary Gems for your GitLab install:
