Deploys a new MongoDB Replica Set. The database cluster will be automatically added to ClusterControl once deployed. A minimum of three nodes (including mongo arbiter) is recommended.
Attention
It is possible to deploy only 2 MongoDB nodes (without an arbiter). The caveat of this approach is no automatic failover. If the primary node goes down then manual failover is required to make the other server runs as primary. Automatic failover works fine with 3 nodes and more.
General & SSH Settings
Field
Description
SSH User
Specify root if you have root credentials.
If you use sudo to execute system commands, specify the name that you wish to use here. The user must exist on all nodes. See Operating System User.
SSH Key Path
Specify the full path of SSH key (the key must exist in the ClusterControl node) that will be used by SSH User to perform passwordless SSH. See Passwordless SSH.
Sudo Password
If you use sudo with password, specify it here. Ignore this if SSH User is root or sudoer does not need a sudo password.
SSH Port
Specify the SSH port for target nodes. ClusterControl assumes SSH is running on the same port on all nodes.
Cluster Name
Specify a name for the cluster.
Install Software
Check the box if you use clean and minimal VMs. Existing MySQL dependencies will be removed. New packages will be installed and existing packages will be uninstalled when provisioning the node with the required software. – If unchecked, existing packages will not be uninstalled, and nothing will be installed. This requires that the instances have already provisioned the necessary software.
Disable Firewall
Check the box to disable the firewall (recommended).
Disable AppArmor/SELinux
Check the box to let ClusterControl disable AppArmor (Ubuntu) or SELinux (RedHat/CentOS) if enabled (recommended).
Location of MongoDB data directory. Default is /var/lib/mongodb.
Admin User
MongoDB admin user. ClusterControl will create this user and enable authentication.
Admin Password
Password for MongoDB Admin User.
Server Port
MongoDB server port. The default is 27017.
mongodb.conf Template
MongoDB configuration template file under /etc/cmon/templates or /usr/share/cmon/templates. See Base Template Files for details.
ReplicaSet Name
Specify the name of the replica set, similar to replication.replSetName option in MongoDB.
Repository
Use Vendor Repositories – Provision software by setting up and using the database vendor’s preferred software repository. ClusterControl will always install the latest version of what is provided by the database vendor repository.
Do Not Setup Vendor Repositories – Provision software by using repositories already set up on the nodes. The User has to set up the software repository manually on each database node and ClusterControl will use this repository for deployment. This is good if the database nodes are running without internet connections.
Use Mirrored Repositories – Create and mirror the current database vendor’s repository and then deploy using the local mirrored repository. This is a preferred option when you have to scale the MongoDB in the future, to ensure the newly provisioned node will always have the same version as the rest of the members.
Add Nodes
Specify the IP address or hostname of the MongoDB nodes. A minimum of three nodes is required.
Deploy
Starts the MongoDB ReplicaSet deployment.
Attention
Starting from ClusterControl 1.9.7 (September 2023), ClusterControl GUI v2 is the default frontend graphical user interface (GUI) for ClusterControl. Note that the GUI v1 is considered a feature-freeze product with no future development. All new developments will be happening on ClusterControl GUI v2. See User Guide (GUI v2).
