nuxt pm2使用、启动、问题解决方案

本文主要是介绍nuxt pm2使用、启动、问题解决方案，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

pm2简介

pm2是一个进程管理工具,可以用它来管理node进程，并查看node进程的状态，当然也支持性能监控，进程守护，负载均衡等功能，在前端和nodejs的世界中用的很多

pm2安装

安装pm2:

$ npm install -g pm2

查看pm2的安装路径:

$whereis pm2

查看安装的pm2的版本:

$pm2 -v

正常启动完项目之后,第一步保存当前进程状态

$ pm2 save

第二步:生成开机自动启动脚本

$ pm2 startup

nuxt安装

指定安装版本

$npm install
$npm install nuxt@2.8.1

nuxt配置

package.json

{"name": "dc","version": "1.2.0","author": "it","private": true,"scripts": {"build": "nuxt build","start": "nuxt start","dev-build": "cross-env NODE_ENV=dev nuxt build","dev": "nuxt"},"dependencies": {"@nuxt/babel-preset-app": "^2.11.0","@nuxtjs/axios": "^5.5.4","@nuxtjs/pwa": "^2.6.0","@nuxtjs/style-resources": "^0.1.2","@tinymce/tinymce-vue": "^3.2.8","@vue/composition-api": "^1.0.0-beta.22","better-scroll": "^1.15.2","cookie-universal-nuxt": "^2.1.4","cookieparser": "^0.1.0","cross-env": "^5.2.0","echarts": "^5.1.1","element-china-area-data": "^4.1.2","element-ui": "^2.9.1","gsap": "^2.1.2","jquery": "^3.4.1","js-cookie": "^2.2.1","js-md5": "^0.7.3","less": "^3.9.0","less-loader": "^5.0.0","log4js": "^6.3.0","nuxt": "^2.12.1","qrcodejs2": "0.0.2","timeago.js": "^4.0.0","tinymce": "^4.8.2","vant": "^2.4.5","vconsole": "^3.7.0","vue-awesome-swiper": "3.1.3","vue-cropperjs": "^4.0.0","vue-lazyload": "^1.3.3","vue-seamless-scroll": "^1.1.17","vue-video-player": "^5.0.2","weixin-js-sdk": "^1.4.0-test"},"devDependencies": {"@nuxtjs/eslint-config": "^0.0.1","babel-eslint": "^10.0.1","es6-promise": "^4.2.8","eslint": "^5.15.1","eslint-config-prettier": "^4.1.0","eslint-config-standard": ">=12.0.0","eslint-loader": "^2.1.2","eslint-plugin-import": ">=2.16.0","eslint-plugin-jest": ">=22.3.0","eslint-plugin-node": ">=8.0.1","eslint-plugin-nuxt": ">=0.4.2","eslint-plugin-prettier": "^3.0.1","eslint-plugin-promise": ">=4.0.1","eslint-plugin-standard": ">=4.0.0","eslint-plugin-vue": "^5.2.2","nodemon": "^1.18.9","prettier": "^1.16.4","swiper": "^5.4.5"}
}

env.js配置

export default {
development: {baseUrl: 'http://aac.com',oldUrl: 'http://test.com',gcUrl: 'http://test2.com',ajaxUrl: 'test2.com',appAjaxUrl: 'https://apitest.com',mdAjaxUrl: 'https://test2com/log4me',host: '0.0.0.0',port: 5000},production: {baseUrl: 'https://test.com',gcUrl: 'https://test.com',ajaxUrl: 'test.com',appAjaxUrl: 'http://apitest.com',staticUrl: 'https://static.com',mdAjaxUrl: 'https://test.com/log4me',port: 5010,host: '0.0.0.0',publicPath: ''}
}

编译

$npm run build

启动pm2

$pm2 -i 2 -n hll start ./node_modules/.bin/nuxt -- start;

-i –instances：启用多少个实例，可用于负载均衡。如果-i 0或者-i max，则根据当前机器核数确定实例数目

查看pm2

$pm2 list

#启动进程(需要进入该项目所在目录下)
pm2 start 进程名

#常用入参

指定应用程序名称

–name <app_name>

当文件更改时，重启应用程序

–watch

为应用程序重新加载设置内存阈值

–max-memory-restart <200MB>

指定日志文件

–log <log_path>

向脚本传递额外的参数

– arg1 arg2 arg3

自动重启之间的延迟

–restart-delay

在日志前面加上时间前缀

–time

不要自动重启应用程序

–no-autorestart

为强制重启指定cron

–cron <cron_pattern>

附加到应用程序日志

–no-daemon
