Disable Transparent Huge Pages (THP)

MongoDB may experience performance degradation and memory fragmentation when THP is enabled. It is recommended to disable it via a systemd service before starting MongoDB.

Create Database Users

Operate on MongoDB Node01

Temporarily start a MongoDB service without connection authentication

su -c '/usr/local/mongodb/bin/mongod --fork --logpath /data/logs/mongodb/mongodb.log --dbpath /data/mongodb --noauth --port 27017' -s /bin/bash mongodb

The root user's password for the MongoDB admin database specified in the command is 123456. It is essential to modify it to a strong password for actual deployment.
The password for the MongoDB business database user hap specified in the command is 123456. It is essential to modify it to a strong password for actual deployment.
If the password contains special characters, only - or _ are allowed. Characters like @ ! # & are prohibited to avoid compatibility issues.
