Create-custer is a small script used to easily start a big number of Redis
instances configured to run in cluster mode. Its main goal is to allow manual
testing in a condition which is not easy to replicate with the Redis cluster
unit tests, for example when a lot of instances are needed in order to trigger
a give bug.
The tool can also be used just to easily create a number of instances in a
Redis Cluster in order to experiment a bit with the system.
USAGE
---
To create a cluster, follow this steps:
1. Edit create-cluster and change the start / end port, depending on the
number of instances you want to create.
2. Use "./create-cluster start" in order to run the instances.
3. Use "./create-cluster create" in order to execute redis-trib create, so that
an actual Redis cluster will be created.
4. Now you are ready to play with the cluster. AOF files and logs for each instances are created in the current directory.
In order to stop a cluster:
1. Use "./craete-cluster stop" to stop all the instances. After you stopped the instances you can use "./create-cluster start" to restart them if you change ideas.
2. Use "./create-cluster clean" to remove all the AOF / log files to restat with a clean environment.
It is currently hardcoded that you start a cluster where each master has one slave, since the script is pretty basic.
