privileges during installation and operation. In some cases, services perform modifications to the host that can interfere with deployment automation tools such as Ansible, Chef, and Puppet. For example, some OpenStack services add a root wrapper to <code class="">sudo</code> that can interfere with security policies. See the <a class="" href="http://docs.openstack.org/admin-guide-cloud/content/root-wrap-reference.html" target="_top">Cloud Administrator Guide</a> for more information. Also, the Networking service assumes default values for kernel network parameters and modifies firewall rules. To avoid most issues during your initial installation, we recommend using a stock deployment of a supported distribution on your hosts. However, if you choose to automate deployment of your hosts, review the configuration and policies applied to them before proceeding further.</p></div><div class=""><div class=""><h2 class="" style="font-stretch:normal;font-size:12pt;font-family:Arial,Helvetica,geneva;color:rgb(204,0,0);clear:both"><a id="basics-networking"> </a>Networking</h2></div><div class=""><dl><dt><span class=""><a href="http://docs.openstack.org/juno/install-guide/install/yum/content/ch_basic_environment.html#basics-networking-neutron">OpenStack Networking (neutron)</a></span></dt><dt><span class=""><a href="http://docs.openstack.org/juno/install-guide/install/yum/content/ch_basic_environment.html#basics-networking-nova">Legacy networking (nova-network)</a></span></dt></dl></div><p style="font-stretch:normal;font-size:10pt">After installing the operating system on each node for the architecture that you choose to deploy, you must configure the network interfaces.

<p><span>After you install the Identity service, create </span><span>tenants</span><span> (projects), </span><span>users</span><span>, and </span><span>roles</span><span> for your environment. You must use the temporary administration token that you created in <a href="http://docs.openstack.org/juno/install-guide/install/yum/content/keystone-install.html" target="_blank"><span>the section called “Install and configure”</span></a> and manually configure the location (endpoint) of the Identity service before you run <b>keystone</b> commands.</span></p>
<p><span>You can pass the value of the administration token to the <b>keystone</b> command with the </span><span>--os-token</span><span> option or set the temporary </span><span>OS_SERVICE_TOKEN</span><span> environment variable. Similarly, you can pass the location of the Identity service to the <b>keystone</b> command with the </span><span>--os-endpoint</span><span> option or set the temporary </span><span>OS_SERVICE_ENDPOINT</span><span> environment variable. This guide uses environment variables to reduce command length.</span></p>
<p><span>For more information, see the <a href="http://docs.openstack.org/openstack-ops/content/projects_users.html" target="_blank"><span>Operations Guide - Managing Project and Users</span></a>.</span></p>

<p><span><b>To configure prerequisites</b></span></p>
