Ubuntu 8.04 Hardy和node.js新贵脚本

Question

I am trying to write an upstart script for my ubuntu machine, which is version 8.04 "Hardy". I have followed the instructions on this site: upstart for node.js but it seems like these instructions are for a current version of ubuntu.

I noticed that the /etc/init directory does not exist on my machine, first I tried putting the script in the /etc/init.d directory and then I created the /etc/init dir and placed it there.

I will post my upstart script below (which is basically the same as from the website above with some path changes), but when I run start jobname, I just get an error "start: Unknown job: jobname". So then I changed the script around to a slimmed down version, posted below, and still I get the same result.

For now, I am using the 'nohup' command to run my node server but I would like a more permanent solution.

Please, any help?

SCRIPT 1:

description "node.js chat server"
author      "iandev ith3"

# used to be: start on startup
# until we found some mounts weren't ready yet while booting:
start on started mountall
stop on shutdown

# Automatically Respawn:
respawn
respawn limit 99 5

script
    # Not sure why $HOME is needed, but we found that it is:
    export HOME="/root"

    exec /root/local/node/bin/node /home/ian/chat.js >> /var/log/node.log 2>&1
end script

post-start script
   # optionally put a script here that will notifiy you node has (re)started
   # /root/bin/hoptoad.sh "node.js has started!"
end script

SCRIPT 2:

description "node.js chat server"
author      "iandev ith3"

script
    exec /root/local/node/bin/node /home/ian/chat.js >> /var/log/node.log 2>&1
end script

From looking at the website you provided I'd say that the /etc/init was just a typo and it should be /etc/init.d/. Some things you may want to check:

• executable flag on your scripts. With most versions of Ubuntu executable files show up green when running 'ls' from the command line. If you want to check if your file is executable run 'ls -l /etc/init.d/YOUR_SCRIPT' from the command line. You will see something like this: -rwxr-xr-x 1 root root 1342 2010-09-16 10:13 YOUR_SCRIPT The x's mean that it is executable. To set the executable flag if it is not set, run chmod u+x YOUR_SCRIPT

• I'm pretty sure for older versions of ubuntu you need to have the script in /etc/rc.d/rc3.d or /etc/rc3.d. What linux does is run through rc0.d to rc5.d and execute every script in there. From what it looks like, ubuntu is moving away from this to something simpler so if you have rc directories you may need to edit your script a little.

Anyway I think i'm getting a little over complicated here. Check your executable flag and if you have rc directories and we'll move on from there.

May not be the best thing to start a process with sudo, but here's what I have setup on my local pc:

#!upstart
description "node.js server"
author      "alessio"

start on startup
stop on shutdown

script
    export HOME="/ubuntu"

    exec sudo -u ubuntu /usr/bin/node /home/ubuntu/www/test.js 2>&1 >> /var/log/node.log
end script

Hope this helps.
