Deploy a Replica Set

Whaleal provides a wizard for adding your existing MongoDB deployments to monitoring and management. The wizard prompts you to:

• Install the Agent if you don't have it installed
• Identify the sharded cluster, the replica set, or the standalone to add.

Considerations

Unique Names for Replica Set

Use a unique name for the replica set.

Procedure

Navigate to the Deployment page for your project.

1. If it is not already displayed, select your desired project from the Projects menu in the navigation bar.

2. If it is not already displayed, click MongoDB in the sidebar.

Open the Cluster Creation View.

Click the Create Cluster arrow in the top-right of the MongoDB page. Select Replica Set from the drop-down menu to open the Create New Replica Set view.

Configure Cluster-Wide Settings.

The Replica Set Configuration section contains the following cluster-wide configuration settings. Settings marked with an * asterisk in the Whaleal UI are required**.

Setting	Description
Project	Select the Project name of your replica set deployment. You cannot change this once set.
Cluster Name	The name of the replica set. It must be a unique name.
BindIp	The BindIp setting in MongoDB specifies the IP addresses that the MongoDB server will listen on for incoming connections.
Version	Select the MongoDB server version of the mongod process.
AuthLevel	Select authentication method

Configure each Replica Set Member.

Whaleal lists each replica set member under the MongoD Settings heading of the Member Configuration section. Each replica set member has the following options:

Setting	Description
Member	Select one of the following replica set member roles from the menu: Ordinary member nodeA data-bearing member of the replica set that can become the primary and vote in elections. Hidden nodeA data-bearing member of the replica set that can vote in elections. Corresponds to the hidden replica configuration option. Hidden delay nodeA data-bearing member of the replica set that can vote in elections.
Hostname	Select from the menu the host to which Whaleal Automation deploys the replica set member. The menu only lists hosts under Whaleal Automation. For complete documentation on adding servers to Whaleal Automation.This hostname can be a hostname or an IPv4 address.
Port	Specify the IANA port number for the mongodprocess. This setting corresponds to the net.port configuration file option.The mongod must have exclusive access to the specified port. If deploying multiple mongod processes to a single host, you must select a unique unused port for each process.
Votes	Specify the number of votes that the replica set member has during elections. This setting corresponds to the votes mongod replica set configuration option.
Priority	Specify the priority of the member during elections. Replica set members with a priority of 0 cannot become the primary node and cannot trigger elections. This setting corresponds to the priority mongod replica set configuration option.
Delay	Specify the number of seconds "behind" the primary member this member should "lag". This setting corresponds to the secondaryDelaySecs mongodreplica set configuration option.
Data Directory	Specify the directory where the mongod process stores data files. This setting corresponds to the storage.dbPath mongod configuration file option. The Whaleal Automation must have file system permission to read, write, and execute all files and folders in the specified directory.Each mongod process must have its own database directory. If deploying multiple mongod processes on the same host, ensure each process has its own distinct directory.It is recommended to mount a separate disk under the /data directory and specify the MongoDB data storage directory under /data.
Log File	The log file and data file are in the same directory, and the directory cannot be customized.
Build Indexes	Specify true to direct the mongod to build indexes. This setting corresponds to the buildIndexes mongod replica set configuration option.

Configure your Replication Settings.

The Replication Settings section contains the following configuration options for the replica set:

Setting	Description
Protocol Version	Select the replication protocol version used by the replica set. This setting corresponds to the protocolVersion replica set configuration option.
Chaining Allowed	Specify true to allow secondary members to replicate from other secondary members. This setting corresponds to the chainingAllowed replica set configuration option.
Write Concern Majority Journal Default	Determines the behavior of {w:"majority"} write concern if the write concern does not explicitly specify the journal option j. This setting corresponds to the writeConcernMajorityJournalDefault replica set configuration option.
Heartbeat Timeout (secs)	Specify the number of seconds that the replica set members wait for a successful heartbeat from each other. This setting corresponds to the heartbeatTimeoutSecs replica set configuration option.
Election Timeout (ms)	Specify the time limit in milliseconds for detecting when a replica set's primary is unreachable. This setting corresponds to the electionTimeoutMillis replica set configuration option.
CatchUp Timeout (ms)	Specify the time limit in milliseconds for a newly elected primary to sync, or catch up, with the other replica set members that may have more recent writes. This setting corresponds to the catchUpTimeoutMillis replica set configuration option.
CatchUp Takeover Delay (ms)	Specify the time in milliseconds a node waits to initiate a catchup takeover after determining it is ahead of the current primary. This setting corresponds to the catchUpTakeoverDelayMillis replica set configuration option.

Set the default read and write concerns for your MongoDB replica set.

In the Default Read Concerns/Write Concerns card, you configure the default level of acknowledgement requested from MongoDB for read and write operations for this cluster. Setting the default read and write concern can help with MongoDB 5.0 and later deployments using arbiters.

From the Default Read Concerns section, you can set consistency and isolation properties for the data read from the cluster.

Set any advanced configuration options for your MongoDB replica set.

The Advanced Configuration Options section allows you to set MongoDB runtime options for each MongoDB process in your deployment.

To add an option:

1. Click Advanced Configuration.

1. Click Add Option and select the configuration option.

2. Whaleal displays a context-sensitive input for configuring an acceptable value for the selected option.

3. Click Confirm to add the selected option and its corresponding value to every process of the selected process type in the cluster.

Click Create Replica Set.

Whaleal automatically deploys the replica set as configured. You can monitor the progress of cluster deployment from the Deployment view.
