Get Started with MongoDB Ops Manager

On this page

  • Prerequisites
  • Create a Cluster
  • Retrieve the Cluster
  • Watch Your Automation Configuration Status
  • Summary

MongoDB CLI provides a command-line interface for managing your MongoDB Ops Manager projects and clusters.

This tutorial demonstrates how to:

  • Create clusters in your Ops Manager project
  • Retrieve details about the new cluster

The reference pages for the commands mentioned in this tutorial are available in the MongoDB CLI Commands.

Before you begin, complete the following tasks:

Use the mongocli ops-manager clusters create command to create a cluster in Ops Manager.

The following command creates a sample cluster with the following settings:

  • Cluster name: getStarted
  • MongoDB server version: 5.0.0
  • Feature compatibility version: 5.0
  • Replica set members: 3
  • Member hostnames: host1, host2, host3

    Note

    This tutorial uses the hostnames host1, host2, and host3. Replace these hostnames with valid MongoDB server hostnames.

  • Data directories for each mongod instance: /data/cluster/rs1, /data/cluster/rs2, /data/cluster/rs3
  • Log file path for each mongod instance: /data/cluster/rs1/mongodb.log, /data/cluster/rs2/mongodb.log, /data/cluster/rs3/mongodb.log
  • Port for each mongod process: 29010, 29020, 29030
  • Voting priority for each member: 1
  • Number of votes for each member: 1
1

To learn more about the configuration file properties, see Cluster Configuration File.

{
"name": "getStarted",
"version": "5.0.0",
"featureCompatibilityVersion": "5.0",
"processes": [
{
"hostname": "host1",
"dbPath": "/data/cluster/rs1",
"logPath": "/data/cluster/rs1/mongodb.log",
"priority": 1,
"votes": 1,
"port": 29010
},
{
"hostname": "host2",
"dbPath": "/data/cluster/rs2",
"logPath": "/data/cluster/rs2/mongodb.log",
"priority": 1,
"votes": 1,
"port": 29020
},
{
"hostname": "host3",
"dbPath": "/data/cluster/rs3",
"logPath": "/data/cluster/rs3/mongodb.log",
"priority": 1,

}
]
}

mongocli ops-manager cluster create --file getStartedCluster.json

You can check whether your cluster was successfully created by retrieving the cluster details using the mongocli ops-manager clusters describe command.

mongocli ops-manager cluster describe getStarted

Your command output should look similar to the following:

{
"mongoURI": "mongodb://host1:29010,host2:29020,host3:29030",
"name": "getStarted",
"processes": [
{
"buildIndexes": true,
"db_path": "/data/cluster/rs1",
"featureCompatibilityVersion": "5.0",
"hostname": "host1",
"log_path": "/data/cluster/rs1/mongodb.log",
"name": "getStartedCluster",
"port": 29010,
"priority": 1,
"process_type": "mongod",
"slave_delay": 0,
"version": "5.0.0",
"votes": 1,
"arbiter_only": false,
"disabled": false,
"hidden": false
},
{
"buildIndexes": true,
"db_path": "/data/cluster/rs2",
"featureCompatibilityVersion": "5.0",
"hostname": "host2",
"log_path": "/data/cluster/rs2/mongodb.log",
"name": "getStartedCluster",
"port": 29020,
"priority": 1,
"process_type": "mongod",
"slave_delay": 0,
"version": "5.0.0",
"votes": 1,
"arbiter_only": false,
"disabled": false,
"hidden": false
},
{
"buildIndexes": true,
"db_path": "/data/cluster/rs3",
"featureCompatibilityVersion": "5.0",
"hostname": "host3",
"log_path": "/data/cluster/rs3/mongodb.log",
"name": "getStartedCluster",
"port": 29030,
"priority": 1,
"process_type": "mongod",
"slave_delay": 0,
"version": "5.0.0",
"votes": 1,
"arbiter_only": false,
"disabled": false,
"hidden": false
}
]
}

Run the mongocli ops-manager automation watch command to determine if the cluster is ready for use. The following command uses the default profile to access the Ops Manager project:

mongocli om automation watch

Congratulations! You have successfully created a cluster to host your data. You can connect to your cluster using the connection string for mongosh or your application or view your cluster by logging in to the UI.
