nodejs cluster
- First, require the 'cluster' module in your Node.js application using the require() function.
- Then, check if the current process is the master process using the cluster.isMaster property.
- If the current process is the master process, get the number of CPU cores using the os module and create worker processes for each core.
- Next, listen for the 'exit' event on the worker processes and create a new worker if any of them exit.
- If the current process is not the master process, start the server or perform the necessary operations for the worker process.
