After repeating steps 1 through 3 on each of the physical hosts that will contain <strong>MySQL</strong><br />
<strong>Cluster</strong> nodes to be managed, the system looks like Figure 5 below.<br />
Figure 5: <strong>MySQL</strong> <strong>Cluster</strong> Manager Agents running on each host<br />
Creating & Starting a <strong>Cluster</strong><br />
Once the agents have been installed and started, the next step is to set up the entities that<br />
will make up the managed <strong>Cluster</strong>(s). As a prerequisite, the installation files for the version<br />
(s) of <strong>MySQL</strong> <strong>Cluster</strong> that are to be managed should be stored in a known location – in this<br />
example, /usr/local/mysql_X_Y_Z.<br />
As in step 4 from section 1.3.2 connect to the agent process running on any of the physical<br />
hosts – from there the whole process of creating all entities needed for the <strong>Cluster</strong> (site,<br />
hosts, packages and <strong>Cluster</strong>) and then starting the <strong>Cluster</strong> can be performed.<br />
1. Define the site – that is, the set of hosts that will run <strong>MySQL</strong> <strong>Cluster</strong> processes that need<br />
to be managed:<br />
mcm> create site --hosts=192.168.0.10,192.168.0.11,192.168.0.12,192.168.0.13<br />
mysite;<br />
2. Define the package(s) that will be used for the <strong>Cluster</strong>; further packages can be added<br />
later (for example when upgrading to the latest <strong>MySQL</strong> <strong>Cluster</strong> release). In this<br />
