| bn_work | hi, I know upstart has kinda been abandoned but does anyone know of a good guide that talks about how to migrate an older SysV style init script to Upstart? I have looked at the official docs (http://upstart.ubuntu.com/cookbook/) and random blog posts (ex: https://coderwall.com/p/rt0qmg/upstart-a-builtin-alternative-to-god-and-monit , https://nnc3.com/mags/LM10/Magazine/Archive/2007/76/062-068_upstart/article.html) | 18:38 |
|---|---|---|
| bn_work | but haven't seen any real good documentation on how to "translate" to the "new model" | 18:38 |
| bn_work | (note, this is on a Ubuntu 14.04 LTS box which I'm not too keen on upgrading yet) | 18:39 |
| hallyn | shouldn't 14.04 already be upstart? | 18:44 |
| hallyn | the cookbook is the best guide i know of, i'm afraid | 18:44 |
| hallyn | but it shouldn't be hard. upstart scripts were easy to write | 18:44 |
| bn_work | hallyn: it is already upstart but I have software on it that only provides a SysV init script | 18:45 |
| hallyn | ok yeah, just look atthe existing scripts, shoudl be pretty clear how to convert. | 18:46 |
| bn_work | hallyn: there is http://upstart.ubuntu.com/cookbook/#migration-from-system-v-initialization-scripts but it talks nothing about migration | 18:46 |
| bn_work | uh... not really? | 18:46 |
| hallyn | <shrug> | 18:47 |
| hallyn | whch part is causing trouble? | 18:47 |
| bn_work | I was hoping there some kind of table showing how to map the concepts from one to the other? | 18:47 |
| bn_work | an upstart (.conf?) file (job?) isn't a shell script anymore, correct? | 18:48 |
| hallyn | right | 18:48 |
| hallyn | it has 'start on / stop on' for ordering, 'pre-start script' 'script' etc which can be shellscripts (inline) for running, | 18:48 |
| bn_work | I mean honestly the vendor should be doing this but they have no clue, so I'm trying to kinda point them to the right resources | 18:48 |
| hallyn | and the 'expect daemon' or whatever for tracking init | 18:48 |
| hallyn | it doesn't really map bc waht you'd be mapping from is kind of free-form :) | 18:49 |
| bn_work | `expect daemon`? | 18:49 |
| hallyn | http://upstart.ubuntu.com/cookbook/#expect | 18:49 |
| bn_work | yeah, but most init scripts have a basic structure in terms of supporting params like start/stop/status/restart | 18:49 |
| hallyn | best is if you can run the software sothat it just runs in the foreground, | 18:50 |
| hallyn | anyway let's see, maybe someone else here knows of a better guide along the lines of what you want | 18:51 |
| bn_work | ok, just read the entry on `expect [fork|daemon|stop]` | 18:56 |
| bn_work | if it's of any help, the source script I'm trying to adapt is at http://www.reprisesoftware.com/RLM_Enduser.html (under "Starting the rlm server at system boot time on Unix systems") | 19:00 |
| bn_work | seems it supports start/stop | 19:01 |
