推荐答案

您可能还需要考虑使用 upstart 实用程序.它将允许您像服务一样启动、停止和重新启动节点应用程序.Upstart 可以配置为在应用程序崩溃时自动重启.

You may also want to consider using the upstart utility. It will allow you to start, stop and restart you node application like a service. Upstart can configured to automatically restart your application if it crashes.

安装新贵:

sudo apt-get install upstart

为您的应用程序创建一个简单的脚本，如下所示:

Create a simple script for your application that will look something like:

#!upstart
description "my app"

start on started mountall
stop on shutdown

# Automatically Respawn:
respawn
respawn limit 99 5

env NODE_ENV=production

exec node /somepath/myapp/app.js >> /var/log/myapp.log 2>&1

然后将脚本文件 (myapp.conf) 复制到/etc/init 并确保其标记为可执行文件.然后可以使用以下命令管理您的应用程序:

Then copy the script file (myapp.conf) to /etc/init and make sure its marked as executable. Your application can then be managed using the following commands:

sudo start myapp
sudo stop myapp
sudo restart myapp
