When working with MongoDB, it surely comes a time when you want to try to make it scale. First, by adding replica set, then sharding and at least mix it together to create a simple cluster with replication on each shard. Then, you might want to test monitoring or other functionality, so you will need to launch your cluster, configure it.<\/p>\n
If everything goes right, you’ll only need to start all your MongoDB instances. Not a big deal, easy to do it at each restart of your computer, just copy paste the right commands. But what if I need a fresh clean cluster to make my test? To answer this question, I wrote a simple script to easily deploy a local mongo cluster composed of one query router, three configuration routers and two shards, each being a replica set composed of one primary mongod and two secondary mongod.<\/p>\n
This simple project is on my Github under the name simple-mongo-cluster<\/a>. The readme describes on which port you’ll find which mongo. The script provides 5 operations: {init|start|configure|stop|clean}. <\/em>I will quickly describe each of it.<\/p>\n The init<\/em> operation creates all directories needed to store logs and data. All mongo instances will be started with the start<\/em> parameter. To configure the cluster, use configure.<\/em> For the cluster to be configured, you might need to call configure<\/em> twice, because of shards sometimes not being added at first call. The stop<\/em> operation is just about shutting down the whole cluster. At last, clean<\/em> deletes all directories containing the cluster configuration files, data and logs so that you can start a fresh new cluster.<\/p>\n I hope it will help other developers who want to easily test and discover MongoDB cluster possibilities in a local environment as it helps me. If you have any suggestions, just let me know or fork the project, add your script and send me a pull request.<\/p>\n","protected":false},"excerpt":{"rendered":" When working with MongoDB, it surely comes a time when you want to try to make it scale.
