Usage

To run the playbook, follow these steps:

1. Modify Hosts File: Update the hosts file with the appropriate host information.

2. Run the Command:

   ansible-playbook -i ./hosts --private-key ~/.ssh/id_rsa -b mongo-db-main.yaml

   Note: Replace mongo-db-main.yaml with the name of your playbook file.

Configuration

• Default Paths:

  • For Debian family: /opt/mongodb/data/
  • For Redhat family: /var/lib/mongo/

  Modify the default paths in the variable file located in the vars directory if necessary.

• Customization:

  • Adjust the configuration file (in the templates directory) to meet specific requirements.

Authentication

Ensure the private key (id_rsa) is available for authentication.

This playbook simplifies the deployment of MongoDB clusters, providing a standardized and efficient solution for managing MongoDB installations across different Linux distributions. Contributions and feedback are welcome for further enhancements and optimizations.
