Install and configure pm2-windows-service

Pm2-windows-service can install pm2 into windows service to achieve the purpose of starting up and running.

Npm I-g pm2-windows-service

Add pm2 environment variable

Add the system environment variable PM2_HOME=C:\ Users\ JasonYang\ .pm2

Right-click [my computer]-[Properties]-[Advanced system Settings]-[Environment variable]-New [system variable]

Name PM2_HOME

Path C:\ Users\ JasonYang\ .pm2 (this path is based on your own needs)

Installation service

Open a new command line window with administrator privileges and execute the following command to install the service

Pm2-service-install

Perform environment setup? Select n to continue

At this point, the PM2 service has been successfully installed and started. You can view it through Wn+R. Enter services.msc to see the service.

Start the node program

Let's start our own service program app.js with pm2, and then tell pm2 to run my app.js automatically when it is turned on.

Continue under the administrator command line, cd to the directory where app.js is located

Pm2 start app.js-name myapp

View a list of services

Pm2 list

Add to self-startup service

Pm2 save

Pm2 save is important because it saves the NodeJS services currently being managed by pm2 and restores them after power on

At this point, the installation and configuration is complete

After reading the above, the uninstall service pm2-service-uninstall, have you mastered how NPM2 starts the node.js file? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
