Chapters Installing Dashboard Upgrading Dashboard Configuring Dashboard Maintaining Dashboard Using Dashboard Rake API Installing Puppet Dashboard This is a chapter of the Puppet Dashboard 1.2 manual. NAVIGATION Installing Dashboard Upgrading Dashboard Configuring Dashboard Maintaining Dashboard Using Dashboard Rake API Overview Puppet Dashboard is a Ruby on Rails web app that interfaces with Puppet. It will run on most modern Unix-like OSes (including Mac OS X and most Linux distributions), requires a certain amount of supporting infrastructure, and can be deployed and served in a variety of ways. Dashboardʼs web interface supports the following browsers: Chrome (current versions) Firefox 3.5 and higher Puppet Dashboard Manual • Puppet Dashboard 1.2 Manual 2/27 Safari 4 and higher Internet Explorer 8 and higher Installing, in Summary In outline, the steps to get Dashboard running are: Installing the external dependencies Installing the Dashboard code Configuring Dashboard Creating and configuring a MySQL database Testing that Dashboard is working Configuring Puppet Starting the delayed job worker processes Running Dashboard in a production-quality server After completing these tasks, Dashboardʼs main functionality will be on-line and working smoothly. You can then configure Dashboard further and enable optional features If you are trying to upgrade Puppet Dashboard instead of installing it from scratch, see the chapter of this manual on upgrading instead of reading further in this chapter.
