| Epeli | Is it safe to install upstart to Debian Squeeze using apt-get? | 10:30 |
|---|---|---|
| Epeli | I have a clean Squeeze installation and I would like to use upstart instead of init.d scripts | 10:31 |
| jhunt | Epeli: I wouldn't like to say. The version in debian is very old. Keybuk was/is going to update it I believe. | 10:33 |
| Epeli | hmm, maybe I'll just go for Ubuntu | 10:37 |
| bwlang | is it a bad idea do something like this? runlevel RUNLEVEL=1 PREVLEVEL=2; runlevel RUNLEVEL=2 PREVLEVEL=1 to simulate a reboot (without unmounting the filesystems?) | 18:29 |
| JanC | that doesn't exactly simulate a reboot... | 18:35 |
| simensen | I have a legacy app that has "server.sh start" and "server.sh stop" functionality that manages the starting and stopping of a java application (somewhere in there it launches java into the background with & ). Is there an easy/straightforward way to deal with this using upstart? Or do I have to rewrite the script? | 19:42 |
| ion | Move the pre-start stuff from the script to a pre-start section, change “java … &” to “exec java …”, that should be about it. | 19:51 |
| simensen | what would cause "sudo start myjob" to just hang? it never returns to the command prompt. if i control-c ( eventually ) and try to run it again it says it is already started. | 20:58 |
| simensen | and how do i debug these things? i can't seem to be getting any output anywhere. not sure what is going on. as far as i can tell, the code i'm putting in script and/or exec doesn't actually get run. | 20:59 |
| SpamapS | simensen: if your job is mentioned in an 'and' condition in some other job, then start will hang until the other conditions are met. | 21:57 |
| SpamapS | simensen: console output will spit out the program's stdout/stderr on /dev/console | 21:57 |
| SpamapS | simensen: you can also use exec yourprogram | logger .. but that gets tricky with expect fork | 21:58 |
| simensen | yeah, this is getting ridiculous. i thought upstart was supposed to be simple and wanted to try it out but i've already spent a few hours on it and basically haven't gotten anything to work yet. | 21:59 |
| JanC | upstart is simple in some ways, but complicated in other ways ☺ | 22:07 |
| simensen | :) | 22:07 |
| simensen | well, now it just is hanging on my process. | 22:07 |
| simensen | does it get confused sometimes? | 22:07 |
| simensen | because it seems tow ork for a bit, then i think i've messed something up… but if i just rename the script from mysample.conf to mysample2.conf and run it, mysample2.conf runs just fine, but mysample.conf won't run anymore. | 22:08 |
| JanC | yes, currently (at least until Ubuntu 11.04) it gets confused if services fork more or less times than it expects | 22:09 |
| simensen | how do you recover from that? | 22:09 |
| simensen | can you reset it short of restarting the box? | 22:10 |
| JanC | there is a hack that involves attempting to create a process with the PID that upstart expects to see... | 22:11 |
| JanC | I think in your case it might be best to create an upstart job that has no exec stanza though | 22:12 |
| simensen | how so? | 22:12 |
| JanC | no main script/exec stanza I mean | 22:13 |
| JanC | call the server.sh script from the pre/start script/exec stanzas | 22:13 |
| simensen | hm. | 22:13 |
| JanC | pre/post start/stop | 22:13 |
| JanC | I think there is an example in the cookbook about that | 22:13 |
| simensen | which is the best place to run each? i thought i needed at least an exec or script? | 22:13 |
| JanC | not needed | 22:14 |
