新贵 node.js 工作目录 [英] Upstart node.js working directory

问题描述

使用 Upstart 启动 Node.js，当尝试访问 Node.js 中的文件时，它无法在不使用完整路径的情况下访问它们.我需要它来使用工作目录.

Starting Node.js with Upstart, when trying to access files within Node.js it cannot access them without using the full path. I need it to use the working directory.

start on startup
stop on shutdown

script
        echo $$ > /var/run/mynodeapp.pid
        exec sudo -u mynodeapp node server.js >> /var/log/mynodeapp.sys.log 2>&1
end script

pre-start script
        echo "Starting" >> /var/log/mynodeapp.sys.log
end script

pre-stop script
        rm /var/run/mynodeapp.pid
        echo "Stopping" >> /var/log/mynodeapp.sys.log
end script

推荐答案

解决方案是更改脚本内的目录.就我而言，用户是 mynodeapp，节点文件位于用户目录 (/home/mynodeapp/) 中.

The solution is to change directory within the script. In my case, the user is mynodeapp and the node files are in the users directory (/home/mynodeapp/).

script
        chdir /home/mynodeapp/
        echo $$ > /var/run/mynodeapp.pid
        exec sudo -u mynodeapp node server.js >> /var/log/mynodeapp.sys.log 2>&1
end script

我还没有弄清楚 $$ 在 echo 行或 2>&1 上的含义.如果他们知道的话，也许有人会同意这个！

I have yet to find out what $$ means on the echo line or 2>&1. Maybe somebody could chime in with this if they know!
