关于node.js：如何在pm2下运行nuxt？

How to run nuxt under pm2?

我有2个nuxt项目需要在服务器上运行。每当我在本地运行该应用程序时，它似乎都可以使用：npm run dev，但是在服务器上，它需要在子进程下运行，因此我使用pm2。但是，每当我开始使用pm2运行相同的npm脚本时，该过程都会出错。

用于此的命令是：sudo pm2 start npm --name"dev" -- dev，即使我单独运行应用程序也会出错。 sudo pm2 start npm --name"app1" -- app1:dev和sudo pm2 start npm --name"app2" -- app2:dev

这一切是什么意思，pm2不能识别npm命令吗？我在这里缺少参数吗？ ...

额外信息：

服务器：Ubuntu 16.04

npm版本：5.6.0
nuxt版本：1.4.2
pm2版本：3.0.3
节点版本：8.11.1

下面的代码：

1	pm2 start npm --name"anyName" -- run dev

相关讨论

对于那些只想以生产模式启动应用程序的人：

Seeing this page comes up at the top of search results of how to use Nuxt.js with PM2, I thought I should add this answer.

尽管PM2是一个名为ecosystem.config.js的文件，但您只需添加到通用Nuxt应用程序中即可为其提供服务。在您的根项目目录中使用该名称创建一个新文件，并添加以下内容：

module.exports = {
apps: [
{
name: 'NuxtAppName',
exec_mode: 'cluster', // Optional: If you want it run multiple instances.
instances: 'max', // Or a number of instances.
// 'max' auto detects how many CPU cores there are.
// The previous option must exist to use the above.
script: './node_modules/nuxt/bin/nuxt.js',
args: 'start',
},
],
}

现在使用npm run build构建您的应用。

并与pm2 start一起使用。

检查状态pm2 ls。

您的Nuxt.js应用程序现在可以使用了！

资源

尽管JC97的答案很不错，但Nuxt已升级，如果您要分别运行调试，开发，登台和生产设置，则还需要一个更加分隔的生态系统文件

首先将nuxt安装为npm install --save nuxt

在项目文件夹中创建一个名为config的文件夹，此文件夹是nuxt生成的服务器页面中间件和其他目录的同级文件

添加4个.env文件.env.deb，.env.dev，.env.sta，.env.pro用于调试，开发阶段和生产

运行命令pm2生态系统，它将生成默认文件

将默认文件替换为以下文件

它将每个环境创建为一个单独的应用程序

如果只想运行登台版本，则可以将其作为pm2 start ecosystem.config.js --only myapp_sta运行

如果需要，可以一次运行所有4个！

const dotenv = require('dotenv')

const autorestart = true
const watch = false
const maxMemoryRestart = '512M'

module.exports = {
apps: [
{
name: 'myapp_dev',
script: 'npm run clear && npm run dev',
instances: 1,
autorestart,
watch,
max_memory_restart: maxMemoryRestart,
env: dotenv.config({ path: './config/.env.dev' }).parsed
},
{
name: 'myapp_deb',
script: 'npm run clear && npm run deb',
instances: 1,
autorestart,
watch,
max_memory_restart: maxMemoryRestart,
env: dotenv.config({ path: './config/.env.deb' }).parsed
},
{

script: 'npm run clear && npm run sta',
instances: 1,
autorestart,

deploy: {
myapp_dev: {
user: 'zupstock',

repo: '[email protected]:owner/myapp_v1.git',
path: '/',
'post-deploy':
'cd myapp_v1 && npm install && pm2 startOrRestart ecosystem.config.js --only myapp_dev'
}
}
}

对我来说，这适用于单个应用程序

如果有效，请尝试以下命令

1	sudo pm2 start npm -- app1:dev
