Using pm2 to deploy multiple node. js projects, pm2node. js

Preface

I believe everyone knows that in actual project deployment, the node service needs to be automatically started when the server is started. Previously, it was started using the built-in commands of liunx. However, as the number of backend microservices increases. Each time a new program is released. It is too troublesome to modify the script. So we can change it to pm2. I will not talk about it much 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 a configuration file

Pm2 ecosystem

After the generation is complete, an ecosystem. config. js file will be generated,

3. modify the configuration file

Edit ecosystem. config. js

. The master needs to configure the program name, the program STARTUP script. You can.

4. Start the configuration file

Pm2 startOrRestart ecosystem. config. js

5. view the startup status

Pm2 list

Indicates that the program is successfully started.

The script startup command can be combined with nvm to support multiple node versions.
