How to Install and Set Up PM2 on Linux Servers – Guide
One of the most important aspects of a successful deployment is ensuring that all necessary components are properly installed and configured. This includes ensuring that your applications are properly registered with your server, that your user accounts are created and configured, and that any required security measures are in place. Additionally, you must ensure that all data is backed up and stored securely.
If your Node.js app crashes in production, you may be able to fix it by using a different back-end platform.
What is PM2 and why do you need it?
PM2 is a daemon process manager that allows you to keep Node.js applications active forever, reload them without downtime, manage application logging, monitoring and clustering. It also includes features for managing web applications and node-based services.
If your Node.js web server crashes, it can be difficult to determine the status of your application and restart it. PM2 helps automate this process and keeps your application online even if something goes wrong. ..
Installing PM2 on Linux Servers
To install PM2 on a Linux server, you first need to install Node.js and NPM. Then, you can download the PM2 package from the Node Package Manager repositories.
pm2 install pm2
pm2 is a package manager for the Node.js platform that makes it easy to install and manage npm packages.
The -g flag in the above command means that the global scope of the Node.js program is enabled, and you can use PM2 in all your Node.js apps. You may need to add sudo at the beginning of the command, depending on your user account permissions.
Running P-Node Applications
pm2 run my-app
How to run the file: To run the file, you will need to first create a new directory and then copy its contents into that directory. Then, you will need to install Node.js and npm. In order to do this, you can either use the command line or a web browser. Once Node.js and npm are installed, you can then run the following command in your new directory: node index.js
pm2 restart
The “pm2 reset file name” command resets the name of the current file to “file_name.” ..
sudo apt-get purge libreoffice* ..
pm2 stop file name - stops the execution of the file named “pm2_stop” on the local machine.
npm start This will start your Node.js application and run the startup script in the background.
pm2 start npm –name “MyNewName” – yes
Viewing Logs and Statistics
PM2 provides an option to check the logs your application generates. To do so, you can use the pm2 logs command.
I am writing to you about a new project I am working on. It is a unique and exciting project that I believe will change the way people interact with the internet.

Easily deploy Node.js applications to production
PM2 can help you reduce the overhead of having to constantly monitor the status and uptime of your Node.js application. With its built-in load balancer, you can expect greater performance and reliability for your services.
