Start Hyper-Converged Database (HCD) as a stand-alone process

Steps for starting the Hyper-Converged Database (HCD) process when HCD was installed from a binary tarball.

Prerequisite

All nodes in the cluster must have HCD installed from a binary tarball. Cluster may not form if nodes have other distributions and/or flavours of Cassandra other than HCD.

Procedure

Stop HCD on the node if it is running.
Change directory to the <install_dir>.

For example, if HCD is unpacked in /path/to/hcd:
```
cd /path/to/hcd
```
From the installation directory, start the node:
```
bin/hcd cassandra
```

To check that your ring is up and running:

bin/nodetool status

The nodetool command shows the nodes' running status. This example output shows a node running in a normal state (UN) with virtual nodes (vnodes) enabled:

Datacenter: DC1
