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

$npm install
$npm install nuxt@2.8.1

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
