+<p>This installation option provides several wrapped <a class="externalLink" href="https://www.ansible.com/">Ansible</a>-based scripts to deploy, start, stop, and erase an AsterixDB instance on a multi-node cluster without requiring users to interact with each individual node in the cluster.</p></div>

+
+<p>Supported operating systems: <b>Linux</b> and <b>MacOS</b></p>

+
+<p>Install pip on your client machine:</p>

+
+<div>
+<div>
+<pre class="source"> $ pip install ansible
+ $ pip install boto
+ $ pip install boto3
+</pre></div></div>
+
+<p>Note that you might need <tt>sudo</tt> depending on your system configuration.</p>
+<p><b>Make sure that the version of Ansible is no less than 2.2.1.0</b>:</p>
+
+<div>
+<div>
+<pre class="source"> $ ansible --version
+ ansible 2.2.1.0

+<p>Download the AsterixDB distribution package, unzip it, and navigate to <tt>opt/ansible/</tt></p>
+

+
+<div>
+<div>
+<pre class="source"> README  bin  conf  yaml
+</pre></div></div>
+
+<p><tt>bin</tt> contains scripts that deploy, start, stop and erase a multi-node AsterixDB cluster, according to the configuration specified in files under <tt>conf</tt>, and <tt>yaml</tt> contains internal Ansible scripts that the shell scripts in <tt>bin</tt> use.</p>

+<ul>
+
+<li>
+
+<p><b>Nodes and account</b>. Edit the inventory file <tt>conf/inventory</tt> when necessary. You mostly only need to specify the node DNS names (or IPs) for the cluster controller, i.e., the master node, in the <b>[cc]</b> section, and node controllers, i.e., slave nodes, in the <b>[ncs]</b> section. The following example configures a cluster with two slave nodes (172.0.1.11 and 172.0.1.12) and one master node (172.0.1.10).</p>
+
+<div>
+<div>
+<pre class="source"> [cc]
+ 172.0.1.10
+
+ [ncs]
+ 172.0.1.11
+ 172.0.1.12
+</pre></div></div>
+
+<p><b>Configure passwordless ssh from your current client that runs the scripts to all nodes listed in <tt>conf/inventory</tt> as well as <tt>localhost</tt>.</b> If the ssh user account for target machines is different from your current username, please uncomment and edit the following two lines:</p>
+
+<div>
+<div>
+<pre class="source"> ;[all:vars]
+ ;ansible_ssh_user=&lt;fill with your ssh account username&gt;
+</pre></div></div>

+</li>
+<li>
+
+<p><b>Remote working directories</b>. Edit <tt>conf/instance_settings.yml</tt> to change the remote binary directory (the variable &#x201c;binarydir&#x201d;) when necessary. By default, the binary directory will be under the home directory (as the value of Ansible builtin variable ansible_env.HOME) of the ssh user account on each node.</p>

+<p>Deploy the binary to all nodes:</p>
+
+<div>
+<div>
+<pre class="source"> $ bin/deploy.sh
+</pre></div></div>
+</li>
+<li>
+
+<p>Every time before starting the AsterixDB cluster, you can edit the instance configuration file <tt>conf/instance/cc.conf</tt>, except that IP addresses/DNS names are generated and cannot be changed. All available parameters and their usage can be found <a href="ncservice.html#Parameters">here</a>.</p>
+</li>
+<li>
+
+<p>Launch your AsterixDB cluster:</p>
+
+<div>
+<div>
+<pre class="source"> $ bin/start.sh
+</pre></div></div>
+
+<p>Now you can use the multi-node AsterixDB cluster by opening the master node listed in <tt>conf/inventory</tt> at port <tt>19001</tt> (which can be customized in <tt>conf/instance/cc.conf</tt>) in your browser.</p>
+</li>
+<li>
+
+<p>If you want to stop the the multi-node AsterixDB cluster, run the following script:</p>
+
+<div>
+<div>
+<pre class="source"> $ bin/stop.sh
+</pre></div></div>
+</li>
+<li>
+
+<p>If you want to remove the binary on all nodes, run the following script:</p>
+
+<div>
+<div>
+<pre class="source"> $ bin/erase.sh
+</pre></div></div>
