Preface

I believe everyone should know that in actual project deployment, our server needs to automatically start the node service when it starts. In the past, it was started through the command that comes with liunx. But as there are more and more backend microservices. New programs are released every time. Modifying the script is too much trouble. So I switched to PM2. Not much to say below, let’s take a look at the detailed implementation process.

The configuration method is as follows:

1. First install pm2

npm install -g pm2

2. Generate the configuration file

pm2 ecosystem

After the generation is completed, there will be an economy.config.js file,

3. Modify the configuration file

Edit economy.config.js

as shown in the figure. The master needs to configure the program name and program startup script. That’s it

4. Start the configuration file

pm2 startOrRestart ecosystem.config.js

5. Check the startup status
