+h3(#install_web_server). Set up a Web server
+
+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.
+
+Follow the instructions until you see the section that says you are ready to deploy your Ruby application on the production server.

h2(#install). Install the SSO server
On a Debian-based system, install the following package:
<notextile>
-<pre><code>~$ <span class="userinput">sudo apt-get arvados-sso</span>
+<pre><code>~$ <span class="userinput">sudo apt-get install arvados-sso-server</span>
</code></pre>
</notextile>
On a Red Hat-based system, install the following package:
<notextile>
-<pre><code>~$ <span class="userinput">sudo yum install arvados-sso</span>
+<pre><code>~$ <span class="userinput">sudo yum install arvados-sso-server</span>
</code></pre>
</notextile>
</code></pre>
</notextile>
-The SSO server runs from the @/var/www/arvados-sso/current/@ directory. The configuration files in @/etc/arvados/sso/@ are symlinked to @/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@.
+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.
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>$ <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>
Generate a new secret token for signing cookies:
<notextile>
-<pre><code>$ <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>
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:
+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>$ <span class="userinput">ruby -e 'puts rand(2**128).to_s(36)'</span>
-abcdefghijklmnopqrstuvwxyz012345689
+<pre><code>~$ <span class="userinput">editor /etc/arvados/sso/database.yml</span>
</code></pre></notextile>
-Configure the SSO server to connect to your database by updating @/etc/arvados/sso/database.yml@. Replace the @xxxxxxxx@ database password placeholder with the new password you generated above. Be sure to update the @production@ section.

-<pre><code>$ <span class="userinput">edit /etc/arvados/sso/database.yml</span>
-</code></pre></notextile>
+h2(#reconfigure_package). Reconfigure the package
-Create a new database user with permission to create its own databases.
+{% assign railspkg = "arvados-sso-server" %}
+{% include 'install_rails_reconfigure' %}
-<notextile>
-<pre><code>$ <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>
+h2(#client). Create arvados-server client
-Rails will take care of creating the database, based on the information from @/etc/arvados/sso/database.yml@.
+{% assign railshost = "" %}
+{% assign railsdir = "/var/www/arvados-sso/current" %}
+Use @rails console@ to create a @Client@ record that will be used by the Arvados API server. {% include 'install_rails_command' %}
-Alternatively, if the database user you intend to use for the SSO server should not be allowed to create new databases, the user and the database can be created like this:
+Enter the following commands at the console. The values that appear after you assign @app_id@ and @app_secret@ correspond to the values for @sso_app_id@ and @sso_app_secret@, respectively, in the "API server's SSO settings":install-api-server.html#omniauth.

+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:

+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
-If @allow_account_registration@ is false, you may manually create local accounts on the SSO server from the rails console:
