Pm2 instruction description
PM2 is a port service daemon tool, which can centrally manage all PM2 started projects on the host, including port information, project information, and run logs, etc., convenient and easy to manage. 1. Start the project
1, NPM run start pm2 start NPM –name “my-nuxt” — run start
1, node app.js pm2 start app.js –name “my-node”
. 2. Manage projects

Use cases
Pm2 NuXT Project Case Description 1. Start nuXT project
# xueerxingxi /xueerxingxi /xueerxingxi
Git pull CNPM I NPM run build
Pm2 start NPM –name “zoujuan” — run start
#pm2 list check whether the project is successfully started. #pm2 list check whether the project is successfully started. #pm2 list check whether the project is successfully started. pm2 list
# If there is a lot of web code, it indicates that the project is running successfully. Curl 127.0.0.1:4003
# xueerxingxi /xueerxingxi /xueerxingxi
Git pull CNPM I NPM run build
Pm2 restart Zoujuan
#pm2 list check whether the project is successfully started. #pm2 list check whether the project is successfully started. #pm2 list check whether the project is successfully started. Pm2 list 3. Use a script to perform updates
The code is updated and dependencies are installed and packaged with each update, followed by a reboot, so using the SH script to update is the most convenient. 1. Script class capacity
