| diverdude | i made this configscript: http://bin.cakephp.org/view/445950409 and saved it in: /etc/init/nodechatserver.conf. when i run start nodechatserver i get this error messae: start: Rejected send message, 1 matched rules; type="method_call", sender=":1.11" (uid=1000 pid=14091 comm="start nodechatserver ") interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 | 17:21 |
|---|---|---|
| diverdude | comm="/sbin/init"). What am I doing wrong? | 17:21 |
| SpamapS | diverdude: you can't run start/stop on system jobs as non-root | 17:22 |
| diverdude | ahhh | 17:22 |
| diverdude | dog | 17:23 |
| diverdude | doh | 17:23 |
| diverdude | :D | 17:23 |
| diverdude | thx | 17:23 |
| SpamapS | diverdude: sudo is your friend | 17:23 |
| diverdude | yes | 17:23 |
| diverdude | that worked | 17:23 |
| diverdude | bu | 17:23 |
| diverdude | t | 17:23 |
| diverdude | when i do sudo stop nodechatserver i get stop: Unknown instance: | 17:23 |
| SpamapS | that means it died | 17:24 |
| SpamapS | diverdude: you should note that this is not the best way to switch users... | 17:25 |
| SpamapS | exec sudo -u www-data /usr/local/bin/node /home/bdi/www/myproj/Console/Command/Nodejs/ChatHandler/ChatServer.js 2>&1 >> /var/log/nodejs.log | 17:25 |
| SpamapS | diverdude: that creates a PAM session, which can cause issues if the job isn't stopped | 17:25 |
| SpamapS | diverdude: which, btw, it won't be, because there is no such event as "shutdown" | 17:26 |
| diverdude | SpamapS: i see...what is a better way to do it? | 17:26 |
| SpamapS | diverdude: also if you are on Ubuntu 11.10 or later, the job output will be logged, so no need to 2>&1 to a special log.. it will automatically be in /var/log/upstart/name_of_job.log | 17:26 |
| diverdude | ah right | 17:26 |
| diverdude | im in 12.04 | 17:26 |
| SpamapS | diverdude: http://upstart.ubuntu.com/cookbook/#run-a-job-as-a-different-user | 17:27 |
| diverdude | but it would be nice to have the log in a special file though | 17:27 |
| SpamapS | diverdude: also 'startup' is emitted before filesystems are mounted, before the network is up.. WAY too early | 17:27 |
| SpamapS | diverdude: you want 'start on runlevel [2345]' and 'stop on runlevel [^2345]' | 17:27 |
| diverdude | SpamapS: mmm i see....is that easy to do? | 17:29 |
| SpamapS | diverdude: is what easy to do? | 17:30 |
| diverdude | SpamapS: to 'start on runlevel [2345]' and 'stop on runlevel [^2345]' | 17:30 |
| SpamapS | diverdude: yes, just change the two start on / stop on lines in your file | 17:31 |
| diverdude | SpamapS: do you think you could show me an example by modifying http://bin.cakephp.org/view/445950409? | 17:32 |
| SpamapS | diverdude: http://bin.cakephp.org/view/445950409 | 17:37 |
| diverdude | SpamapS: ahhh nice. thanks | 17:41 |
| diverdude | SpamapS: mmm should i restart before i can use it? | 17:42 |
| diverdude | because when i run it i get this: | 17:42 |
| diverdude | $ sudo start nodechatserver | 17:42 |
| diverdude | nodechatserver stop/waiting | 17:42 |
| diverdude | and stop it says this | 17:42 |
| diverdude | $ sudo stop nodechatserver | 17:42 |
| diverdude | stop: Unknown instance: | 17:42 |
| SpamapS | diverdude: your start is very odd. I would check the log for errors | 17:42 |
| SpamapS | diverdude: note that having it in /var/log/upstart/jobname.log will really be easier.. /var/log/nodejs.log is pretty generic, don't you think? | 17:43 |
| diverdude | hmm | 17:49 |
| diverdude | cat /var/log/nodejs.log is totally empty | 17:50 |
| diverdude | cat /var/log/upstart/nodechatserver.log | 17:50 |
| diverdude | cat: /var/log/upstart/nodechatserver.log: Permission denied | 17:50 |
| SpamapS | diverdude: sudo again | 17:55 |
| diverdude | you mean sudo start nodechatserver ? | 17:56 |
| diverdude | i did that | 17:56 |
| SpamapS | no | 17:56 |
| SpamapS | sudo cat /var/log/upstart/nodechatserver.log | 17:56 |
| diverdude | it says start-stop-daemon: unable to stat /usr/local/bin/node (No such file or directory) in the logfile | 18:03 |
| diverdude | but this file exists | 18:03 |
| diverdude | i can run it manually | 18:03 |
| SpamapS | diverdude: interesting | 18:04 |
| SpamapS | diverdude: check for sure that there's no type-o | 18:04 |
| SpamapS | diverdude: and when you say you can run it manually, are you running just /usr/local/bin/node, or the full start-stop-daemon command? | 18:04 |
| diverdude | SpamapS: sorry that was my mistake | 18:11 |
| diverdude | it can run now | 18:11 |
| diverdude | nodechatserver start/running, process 14555 | 18:11 |
| diverdude | however still cannot stop it :( | 18:11 |
| SpamapS | diverdude: how so? | 18:13 |
| SpamapS | diverdude: is it actually running? | 18:13 |
| diverdude | hmm no | 18:16 |
| diverdude | ps aux | grep 14555 shows nothing :( | 18:16 |
| diverdude | ahh i know why | 18:16 |
| diverdude | is it possible to run the process from a certain directory? | 18:17 |
| diverdude | like if i want to cd /somewhere first | 18:17 |
| diverdude | would that by exec start-stop-daemon --start -c www-data --exec cd /home/bdi/www/myproj/Console/Command/Nodejs/ChatHandler/ ; /usr/bin/nodejs -- /home/bdi/www/myproj/Console/Command/Nodejs/ChatHandler/ChatServer.js 2>&1 >> /var/log/nodejs.log ? | 18:18 |
| diverdude | hmm | 18:25 |
| diverdude | its not running | 18:25 |
| SpamapS | diverdude: yes there is a 'chdir' stanza | 18:26 |
| diverdude | even though the output in cat /var/log/nodejs.log looks correct | 18:26 |
| SpamapS | diverdude: don't exec cd | 18:26 |
| SpamapS | diverdude: 'chdir /home/bdi/www/myproj....' at the root of the charm | 18:26 |
| diverdude | SpamapS: i fixed the CD in another way, so thats not necessary after all | 18:26 |
| diverdude | SpamapS: but still for some reason its not running | 18:26 |
| SpamapS | diverdude: actually for your charm, you don't even need start-stop-daemon, you can do 'setuid www-data' and 'setgid www-data' | 18:26 |
| SpamapS | diverdude: does nodejs daemonize? | 18:27 |
| SpamapS | diverdude: like, when you run it from the commandline, does it give you back your shell immediately even though it is running? | 18:27 |
| diverdude | SpamapS: hmm i think so...cant all programs do that? | 18:27 |
| diverdude | SpamapS: i dont know actually | 18:27 |
| diverdude | SpamapS: im pretty sure though...these guys: http://kvz.io/blog/2009/12/15/run-nodejs-as-a-service-on-ubuntu-karmic/ demonised it | 18:28 |
| diverdude | SpamapS: dont you think? | 18:30 |
| SpamapS | *karmic* ? | 18:32 |
| SpamapS | diverdude: thats 3 years old now.. ;) | 18:33 |
| SpamapS | node has come quite a long way since then | 18:33 |
| diverdude | SpamapS: hehe yes...but i dont suppose it has gotten worse? | 18:33 |
| SpamapS | diverdude: but if it is dying.. its not upstart killing it. | 18:33 |
| SpamapS | diverdude: check /var/log/syslog, you should have something like "init: ... exitted with code 1" | 18:33 |
| diverdude | SpamapS: yeah | 18:35 |
| diverdude | init: nodechatserver main process (14722) terminated with status 1 | 18:35 |
| diverdude | SpamapS: what does that mean? | 18:36 |
| SpamapS | diverdude: it means it exitted with an error | 18:37 |
| SpamapS | diverdude: I'm sure your log will show the error | 18:37 |
| diverdude | no | 18:37 |
| diverdude | nothing in the log | 18:37 |
| diverdude | and this runs just fine if i do it manually | 18:39 |
| diverdude | sudo -u www-data /usr/bin/nodejs /home/bdi/www/myproj/Console/Command/Nodejs/ChatHandler/ChatServer.js | 18:39 |
| diverdude | thats very strange | 18:41 |
| diverdude | hmm | 18:41 |
| diverdude | SpamapS: ^ | 18:41 |
| jodh | diverdude: Have you looked at the Upstart Cookbook? Specifically, try: http://upstart.ubuntu.com/cookbook/#checking-how-a-service-might-react-when-run-as-a-job | 18:47 |
| diverdude | jodh: hmm i tried doing: | 19:36 |
| diverdude | user=www-data | 19:36 |
| diverdude | cmd="/usr/bin/node /home/bdi/www/myproject/Console/Command/Nodejs/ChatHandler/ChatServer.js" | 19:36 |
| diverdude | su -c 'nohup env -i $cmd </dev/null >/dev/null 2>&1 &' $user | 19:36 |
| diverdude | and i get: | 19:36 |
| diverdude | su: Authentication failure | 19:37 |
| diverdude | is that the reason for it not running? | 19:37 |
| diverdude | and is my cmd set up correctly? | 19:37 |
| jodh | diverdude: I think you just got that password wrong. | 19:42 |
| diverdude | jodh: no | 19:43 |
| diverdude | i tried 4 times | 19:43 |
| diverdude | SpamapS: are you still there? | 21:11 |
| SpamapS | diverdude: I stepped out for a bit, back now | 22:51 |
| diverdude | SpamapS: start on runlevel [2345] ensures that service is started after network interface cards are up right? | 23:30 |
