与rc.local中运行脚本：脚本工作，但不会在引导 [英] Run script with rc.local: script works, but not at boot

问题描述

我有需要在引导的并启动一个Node.js的剧本的WWW的数据用户下运行。在开发过程中我总是开始与脚本：

I have a node.js script which need to start at boot and run under the www-data user. During development I always started the script with:

su www-data -c 'node /var/www/php-jobs/manager.js

我看到到底发生了什么，在manager.js现在的作品太棒了。搜索SO我发现我有放置这在我的的/etc/rc.local 。另外，我学会了输出指向一个日志文件，并追加 2 - ;＆放大器; 1 来stderr重定向到stdout，它应该是一个守护进程，最后性格是一个＆放大器;

I saw exactly what happened, the manager.js works now great. Searching SO I found I had to place this in my /etc/rc.local. Also, I learned to point the output to a log file and to append the 2>&1 to "redirect stderr to stdout" and it should be a daemon so the last character is a &.

最后，我的的/etc/rc.local 是这样的：

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

su www-data -c 'node /var/www/php-jobs/manager.js >> /var/log/php-jobs.log 2>&1 &'

exit 0

如果我运行这个自己（须藤的/etc/rc.local ）：是的，它的作品！但是，如果我执行重新启动进程正在运行，没有节点，在 /var/log/php-jobs.log 不存在并且因此，manager.js不起作用。这是怎么回事？

If I run this myself (sudo /etc/rc.local): yes, it works! However, if I perform a reboot no node process is running, the /var/log/php-jobs.log does not exist and thus, the manager.js does not work. What is happening?
