 To install the DCOS CLI:
 Install virtualenv. The Python tool virtualenv is used to manage the DCOS CLI’s environment.
 <source lang="bash" enclose="div">
 sudo pip install virtualenv
 </source><br />
 Tip: On some older Python versions, ignore any ‘Insecure Platform’ warnings. For more information, see https://virtualenv.pypa.io/en/latest/installation.html.
 From the command line, create a new directory named dcos and navigate into it.
 <source lang="bash" enclose="div">
 $ mkdir dcos
 $ cd dcos
 $ curl -O https://downloads.mesosphere.io/dcos-cli/install.sh
 </source><br />
 Run the DCOS CLI install script, where &lt;hosturl&gt; is the hostname of your master node prefixed with http://:
 <source lang="bash" enclose="div">
 $ bash install.sh <install_dir> <mesos-master-host>
 </source><br />
 For example, if the hostname of your Mesos master node is mesos-master.example.com:
 <source lang="bash" enclose="div">
 $ bash install.sh . http://mesos-master.example.com
 </source><br />
 Follow the on-screen DCOS CLI instructions and enter the Mesosphere verification code. You can ignore any Python ‘Insecure Platform’ warnings.
 <source lang="bash" enclose="div">
 Confirm whether you want to add DCOS to your system PATH:
 $ Modify your bash profile to add DCOS to your PATH? [yes/no]
 </source><br />
 Since DCOS CLI is used for DCOS cluster, reconfigure Marathon and Mesos masters URLs with the following commands:
 <source lang="bash" enclose="div">
 dcos config set core.mesos_master_url http://<mesos-master-host>:5050
 dcos config set marathon.url http://<marathon-host>:8080
 </source><br />
 <br /><br />
