MongoDB 8.2 can be installed on Ubuntu 24.04 by adding the official MongoDB repository, importing the GPG key, and installing the mongodb-org package. The database is managed through systemd commands and configured via /etc/mongod.conf. Essential security steps include enabling authentication with role-based access control, restricting network access through bindIp settings and firewall rules, and implementing TLS encryption for data in transit. Production deployments require regular backups using mongodump or volume snapshots, monitoring with mongostat and mongotop, and proper maintenance including log rotation and disk space management. Scaling options include replica sets for high availability and sharding for horizontal scaling. The guide covers troubleshooting common issues like startup failures, connection problems, and performance degradation.
