yarn global add pm2

How to

Suppose you need to manage a bot group that uses Binance Futures for trading through pm2. The group contains two bots and one price update thread. you need

Create a binanceusdm.config.js file under /config/

javascript

module.exports = {
   apps: [
     {
       name: 'server', //price update
       script: './xcoin.js',
       cron_restart: "50 */6 * * *",//restart every 6 hours
       restart_delay: 100,
       args: 'server binanceusdm --conf ./data/config/binanceusdm/1mf.json'//run the specified configuration file
     }
     ,
     {
       name: 'trade', //30-minute cycle trading thread
       script: './xcoin.js',
       watch: ['./data/pm2/restart_binanceusdm_rain.json'], //restart when the file is changed
       args: 'trade binanceusdm --conf ./data/config/binanceusdm/30mf.json --with_server'//run the specified configuration file
     },
     {
       name: 'trade1m', //1 minute cycle trading thread
       script: './xcoin.js',
       watch: ['./data/pm2/restart_binanceusdm_demo.json'], //restart when the file is changed
       args: 'trade binanceusdm --conf ./data/config/binanceusdm/1mf.json --with_server'//run the specified configuration file
     }
   ]
};

Add in the pakcage.json file

javascript

"binanceusdm": "pm2 start ./config/binanceusdm.config.js",

Terminal operation

bash

yarn binance usdm

View the current running status through pm2
- pm2 list get all running tasks
- pm2 monit to see all output from tasks
- pm2 delete all terminates all tasks
- pm2 restart server restarts the server task
When the client configuration changes and the server needs to be restarted, run the following in the websocket.js code

javascript

if (message. restart) {
        console.log('\nSome Core Param changed.should restart process...'.orange)
        var target3 = require('path').resolve(__dirname, '../../data/pm2/restart_' + s.options.exchange + "_" + (s.options.name || '') + '.json')
        require('fs').writeFileSync(target3, JSON.stringify({ event: 'updateConfig', time: moment().format('MMDD HH:mm:ss') }, null, 2))
    }

Running multiple bots on different exchanges

If you want to run multiple bots based on different exchanges through pm2, you only need to repeat the above steps, such as trading matcha products through yarn mexc. Notice

The task name cannot be repeated
It is better to use a new name for the name on config.base to avoid duplication of restart files
