Using process manager PM2
PM2 is a popular process manager for running nodejs in the background in a production environment First choice. It provides many features and options, including process monitoring, automatic restart, load balancing, and more. After using PM2, we can easily run nodejs applications in the background.

npm install -g pm2
Start the nodejs application
When starting the application, using PM2 is very simple, just enter the following command in the terminal:
pm2 start app.js
The app.js here is the entry file of our nodejs application. PM2 will automatically create a background process to run this file.
PM2 also provides many useful commands that we can use to manage the nodejs process. The following are some of the most commonly used commands:
pm2 list # 列出所有进程 pm2 stop <app-name> # 停止指定应用程序 pm2 restart <app-name># 重启指定应用程序 pm2 delete <app-name> # 删除指定应用程序
Using nohup
nohup node app.js &The app.js here is our nodejs application entry file. The "&" symbol means transferring the command to the background for execution. End runningWhen we need to stop a nodejs application running in the background, we need to first use the ps command to find the process ID of the application, and then use the kill command to end the process:
ps -ef | grep node # 找到进程 ID kill <pid> # 结束进程

This article discusses how to improve Hadoop data processing efficiency on Debian systems. Optimization strategies cover hardware upgrades, operating system parameter adjustments, Hadoop configuration modifications, and the use of efficient algorithms and tools. 1. Hardware resource strengthening ensures that all nodes have consistent hardware configurations, especially paying attention to CPU, memory and network equipment performance. Choosing high-performance hardware components is essential to improve overall processing speed. 2. Operating system tunes file descriptors and network connections: Modify the /etc/security/limits.conf file to increase the upper limit of file descriptors and network connections allowed to be opened at the same time by the system. JVM parameter adjustment: Adjust in hadoop-env.sh file
