+For best performance, we recommend you use Nginx as your Web server frontend with a Passenger backend to serve the SSO server. The Passenger team provides "Nginx + Passenger installation instructions":https://www.phusionpassenger.com/library/walkthroughs/deploy/ruby/ownserver/nginx/oss/install_passenger_main.html.
-h2(#install). Install SSO server
+Follow the instructions until you see the section that says you are ready to deploy your Ruby application on the production server.
-h3. Get SSO server code and run bundle
+h2(#install). Install the SSO server
+
+On a Debian-based system, install the following package:
<notextile>
-<pre><code>~$ <span class="userinput">cd $HOME</span> # (or wherever you want to install)
-~$ <span class="userinput">git clone https://github.com/curoverse/sso-devise-omniauth-provider.git</span>
-~$ <span class="userinput">cd sso-devise-omniauth-provider</span>
-~/sso-devise-omniauth-provider$ <span class="userinput">bundle install --without=development</span>
-</code></pre></notextile>
+<pre><code>~$ <span class="userinput">sudo apt-get install arvados-sso-server</span>
+</code></pre>
+</notextile>
-h2. Configure the SSO server
+On a Red Hat-based system, install the following package:
+
+<notextile>
+<pre><code>~$ <span class="userinput">sudo yum install arvados-sso-server</span>
+</code></pre>
+</notextile>
-First, copy the example configuration file:
+h2(#configure). Configure the SSO server
+
+The package has installed three configuration files in @/etc/arvados/sso@:
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">cp -i config/application.yml.example config/application.yml</span>
-</code></pre></notextile>
+<pre><code>/etc/arvados/sso/application.yml
+/etc/arvados/sso/database.yml
+/etc/arvados/sso/production.rb
+</code></pre>
+</notextile>
+
+The SSO server runs from the @/var/www/arvados-sso/current/@ directory. The files @/var/www/arvados-sso/current/config/application.yml@, @/var/www/arvados-sso/current/config/database.yml@ and @/var/www/arvados-sso/current/config/environments/production.rb@ are symlinked to the configuration files in @/etc/arvados/sso/@.
The SSO server reads the @config/application.yml@ file, as well as the @config/application.defaults.yml@ file. Values in @config/application.yml@ take precedence over the defaults that are defined in @config/application.defaults.yml@. The @config/application.yml.example@ file is not read by the SSO server and is provided for installation convenience only.
-Consult @config/application.default.yml@ for a full list of configuration options. Local configuration goes in @config/application.yml@, do not edit @config/application.default.yml@.

h3(#uuid_prefix). uuid_prefix
Generate a uuid prefix for the single sign on service. This prefix is used to identify user records as originating from this site. It must be exactly 5 lowercase ASCII letters and/or digits. You may use the following snippet to generate a uuid prefix:
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">ruby -e 'puts "#{rand(2**64).to_s(36)[0,5]}"'</span>
+<pre><code>~$ <span class="userinput">ruby -e 'puts "#{rand(2**64).to_s(36)[0,5]}"'</span>
abcde
</code></pre></notextile>
-Edit @config/application.yml@ and set @uuid_prefix@ in the "common" section.
+Edit @/etc/arvados/sso/application.yml@ and set @uuid_prefix@ in the "common" section.
h3(#secret_token). secret_token
Generate a new secret token for signing cookies:
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">ruby -e 'puts rand(2**400).to_s(36)'</span>
+<pre><code>~$ <span class="userinput">ruby -e 'puts rand(2**400).to_s(36)'</span>
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
</code></pre></notextile>
-Edit @config/application.yml@ and set @secret_token@ in the "common" section.
-
-h2(#database). Set up the database
-
-Generate a new database password. Nobody ever needs to memorize it or type it, so make a strong one:
-
-<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">ruby -e 'puts rand(2**128).to_s(36)'</span>
-abcdefghijklmnopqrstuvwxyz012345689
-</code></pre></notextile>
-
-Create a new database user with permission to create its own databases.
-
-<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">sudo -u postgres createuser --createdb --encrypted -R -S --pwprompt arvados_sso</span>
-Enter password for new role: <span class="userinput">paste-database-password-you-generated</span>
-Enter it again: <span class="userinput">paste-database-password-you-generated</span>
-</code></pre></notextile>
+Edit @/etc/arvados/sso/application.yml@ and set @secret_token@ in the "common" section.
-Configure SSO server to connect to your database by creating and updating @config/database.yml@. Replace the @xxxxxxxx@ database password placeholders with the new password you generated above. If you are planning a production system, update the @production@ section, otherwise use @development@.
+There are other configuration options in @/etc/arvados/sso/application.yml@. See the "Authentication methods":install-sso.html#authentication_methods section below for more details.
-<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">cp -i config/database.yml.example config/database.yml</span>
-~/sso-devise-omniauth-provider$ <span class="userinput">edit config/database.yml</span>
-</code></pre></notextile>
+h2(#database). Set up the database
-Create and initialize the database. If you are planning a production system, choose the @production@ rails environment, otherwise use @development@.
+Configure the SSO server to connect to your database by updating @/etc/arvados/sso/database.yml@. Replace the @xxxxxxxx@ database password placeholder with the "password you generated during database setup":install-postgresql.html#sso. Be sure to update the @production@ section.
<notextile>
-<pre><code>~/sso-devise-omniauth-provider$ <span class="userinput">RAILS_ENV=production bundle exec rake db:setup</span>
+<pre><code>~$ <span class="userinput">editor /etc/arvados/sso/database.yml</span>
</code></pre></notextile>
-Alternatively, if the database user you intend to use for the SSO server is not allowed to create new databases, you can create the database first and then populate it with rake. Be sure to adjust the database name if you are using the @development@ environment. This sequence of commands is functionally equivalent to the rake db:setup command above:
+h2(#reconfigure_package). Reconfigure the package
-<notextile>

-h2(#assets). Precompile assets
+h2(#configure_web_server). Configure your web server
-If you are running in the production environment, you must precompile the assets:
+Edit the http section of your Nginx configuration to run the Passenger server and act as a frontend for it. You might add a block like the following, adding SSL and logging parameters to taste:
<notextile>

</code></pre>
</notextile>
+Finally, restart Nginx and your Arvados SSO server should be up and running. You can verify that by visiting the URL you configured your Nginx web server to listen on in the server section above (port 443). Read on if you want to configure your Arvados SSO server to use a different authentication backend.
+
h2(#authentication_methods). Authentication methods
Authentication methods are configured in @application.yml@. Currently three authentication methods are supported: local accounts, LDAP, and Google+. If neither Google+ nor LDAP are enabled, the SSO server defaults to local user accounts. Only one authentication mechanism should be in use at a time.
For more information about configuring backend support for sending email (required to send email confirmations) see "Configuring Action Mailer":http://guides.rubyonrails.org/configuring.html#configuring-action-mailer
