PM2 API 无法连接

问题描述

我无法通过 API 连接到 PM2 实例。

以下是代码

var pm2 = require('pm2');

console.log('pm2  ',pm2);

pm2.connect(function (err) {
    console.log('pm2 error ',err);
    if (err) {
        console.error(err);
        process.exit(2);
    }
    else {
        pm2.list(function (err,res) { });
        var pm2 = require('pm2');

    }
});

我得到的错误是

$ sudo node maintanance/manage-pm2.js 
pm2   undefined
(node:56046) [DEP0079] DeprecationWarning: Custom inspection function on Objects via .inspect() is deprecated
pm2 error  null
/home/ubuntu/laks/middleware-2.0/maintanance/manage-pm2.js:12
        pm2.list(function (err,res) { });
            ^

TypeError: Cannot read property 'list' of undefined

是的，当然，我已经安装了“pm​​2”版本 ^4.5.4

解决方法

删除此行 var pm2 = require('pm2'); 您正在重新初始化 pm2 而 pm2.list 仍在运行

processList 会给你 pm2 实例列表

var pm2 = require('pm2');

console.log('pm2  ',pm2);

pm2.connect(function (err) {
    console.log('pm2 error ',err);
    if (err) {
        console.error(err);
        process.exit(2);
    }
    else {
        pm2.list(function (err,processList) { 
            console.log(processList);
        });
    }
});
