PM2用配置文件管理多个Node.js项目！

// ecosystem.config.js
module.exports = {
    apps: [{
        name: "app1",
        script: "./app.js"
    }]
}

module.exports = {
    apps: [{
        script: 'index.js',
        watch: '.'
    }, {
        script: './service-worker/',
        watch: ['./service-worker']
    }],

    deploy: {
        production: {
            user: 'SSH_USERNAME',
            host: 'SSH_HOSTMACHINE',
            ref: 'origin/master',
            repo: 'GIT_REPOSITORY',
            path: 'DESTINATION_PATH',
            'pre-deploy-local': '',
            'post-deploy': 'npm install && pm2 reload ecosystem.config.js --env production',
            'pre-setup': ''
        }
    }
};

pm2 start ecosystem.config.js
pm2 stop ecosystem.config.js
pm2 restart ecosystem.config.js
pm2 reload ecosystem.config.js
pm2 delete ecosystem.config.js

pm2 start   ecosystem.config.js --only api-app
pm2 start 	ecosystem.config.js --only "api-app,worker-app"
