Deploying a development cluster
|
|
=================================
|
|
|
|
In order to develop on ceph, a Ceph utility,
|
|
*vstart.sh*, allows you to deploy fake local cluster for development purpose.
|
|
|
|
Usage
|
|
=====
|
|
|

It allows to deploy a fake local cluster on your machine for development purpose. It starts rgw, mon, osd and/or mds, or all of them if not specified.

|
|
|
|
vstart.sh [OPTIONS]...

In order to stop the cluster, you can type::
|
|
|
|
./stop.sh

Deploying multiple development clusters on the same machine
|
|
============================================================
|
|
|
|
In order to bring up multiple ceph clusters on the same machine, *mstart.sh* a
|
|
small wrapper around the above *vstart* can help.
|
|
|
|
Usage
|
|
=====
|
|
|
|
To start multiple clusters, you would run mstart for each cluster you would want
|
|
to deploy, and it will start monitors, rgws for each cluster on different ports
|
|
allowing you to run multiple mons, rgws etc. on the same cluster. Invoke it in
|
|
the following way::
|
|
|
|
mstart.sh <cluster-name> <vstart options>
|
|
|
|
For eg::
|
|
|
|
./mstart.sh cluster1 -n -r
|
|
|
|
|
|
For stopping the cluster, you do::
|
|
|
|
./mstop.sh <cluster-name>
