|_Function_|_Number of nodes_|
|Arvados API, Crunch dispatcher, Git, Websockets and Workbench|1|
|Arvados Compute node|1|

+|Arvados Keepproxy and Keep-web server|1|
|Arvados Keepstore servers|2|
|Arvados Shell server|1|
|Arvados SSO server|1|
The number of Keepstore, shell and compute nodes listed above is a minimum. In a real production installation, you will likely run many more of each of those types of nodes. In such a scenario, you would probably also want to dedicate a node to the Workbench server and Crunch dispatcher, respectively. For performance reasons, you may want to run the database server on a separate node as well.

h2(#repos). Arvados package repositories
On any host where you install Arvados software, you'll need to set up an Arvados package repository. They're available for several popular distributions.
h3. CentOS
-Packages are available for CentOS 6. First, register the Curoverse signing key in RPM's database:
-
-{% include 'install_redhat_key' %}
-
-Then save this configuration block in @/etc/yum.repos.d/arvados.repo@:
+Packages are available for CentOS 7. To install them with yum, save this configuration block in @/etc/yum.repos.d/arvados.repo@:
<notextile>

+gpgcheck=1
+gpgkey=http://rpm.arvados.org/CentOS/RPM-GPG-KEY-curoverse
</code></pre>
</notextile>
+{% include 'install_redhat_key' %}

h3. Debian and Ubuntu
-Packages are available for Debian 7 ("wheezy"), Ubuntu 12.04 ("precise"), and Ubuntu 14.04 ("trusty").
+Packages are available for Debian 8 ("jessie"), Ubuntu 14.04 ("trusty") and Ubuntu 16.04 ("xenial").
First, register the Curoverse signing key in apt's database:

Most Arvados clients and services will accept self-signed certificates when the @ARVADOS_API_HOST_INSECURE@ environment variable is set to @true@. However, web browsers generally do not make it easy for users to accept self-signed certificates from Web sites.
-Users who log in through Workbench will visit three sites: the SSO server, the API server, and Workbench itself. When a browser visits each of these sites, it will warn the user if the site uses a self-signed certificate, and the user must accept it before continuing. This procedure usually only needs to be done once in a browser.
+Users who log in through Workbench will visit at least three sites: the SSO server, the API server, and Workbench itself. When a browser visits each of these sites, it will warn the user if the site uses a self-signed certificate, and the user must accept it before continuing. This procedure usually only needs to be done once in a browser.
After that's done, Workbench includes JavaScript clients for other Arvados services. Users are usually not warned if these client connections are refused because the server uses a self-signed certificate, and it is especially difficult to accept those cerficiates:
* JavaScript connects to the Websockets server to provide incremental page updates and view logs from running jobs.
* JavaScript connects to the API and Keepproxy servers to upload local files to collections.
+* JavaScript connects to the Keep-web server to download log files.
In sum, Workbench will be much less pleasant to use in a cluster that uses self-signed certificates. You should avoid using self-signed certificates unless you plan to deploy a cluster without Workbench; you are deploying only to evaluate Arvados as an individual system administrator; or you can push configuration to users' browsers to trust your self-signed certificates.
