Despliegue y supervisión

Hey Tim,

Thank you for sharing your workaround with others! Good idea to start the command via CRON ;)

Cheers!

Yo @Dang!

Hmm. I am FAR from an expert on Docker, especially in a production environment. However, I believe that you would have a specific (PHP) container set up for running supervisor and that supervisor would be your main CMD on that container (and you'd run supervisor with nodaemon=true). Again, this is NOT my area of expertise, so I could be misguided, but that's my impression :).

Cheers!

Just in case, the correct link is: http://supervisord.org/runn...

Hey Remi,

Yeah, it makes sense. In our example we use the absolute path so it works. If you use a relative path like only "bin/console" - you have to specify the directory of your project. Thank you for some tips! Might be useful for other users.

About problem with deleting files in a handler. Hm, most probably you have different permissions, so it sounds like permission problem. Is it for all the folders? Or some of them are removed successfully but some are not?

Cheers!

Mmm... Not sure because my filesystem works perfectly in the controller in production... I'll explore further and keep you update (i didn't try it syncronously yet to make a differential diagnosis)

Hey @Rémi Dck

I also believe that the file deletion problem is due to permissions. I think you just have to tell supervisor to run your worker as your web user (usually named as "www"). Here is an example of how to do it but I didn't give it a try: https://stackoverflow.com/a...

Cheers!

OMG you're the best Diego. Thanks a lot !!!
I dug in and the tail is a little bit tricky (to me, i'm not a unix user...)
The first step is finding the web user, like you said and the best command for this is less /etc/passwd. For Ubuntu 18.04 seems to be www-data
Next in messenger-worker.conf change user name and add environnement targeting the home directory of www-data
Aaaand done ! Love it.

Awesome! Excellent job man because I wrote the name wrong, it usually is www-data not just www :p

Hey Marko,

The best strategy is to do a few more retries after some time, and if still no success - move that message into a failed messages queue where you can retry the message manually when the problem will be fixed. That's the strategy we use on SymfonyCasts, and IIRC we covered it in this course :)

Cheers!

Hello Victor! Thanks a lot for your quick answer. Does Supervisor have any role in this issue (in production) ?

Hey Marko,

Supervisor is about a different problem, it helps to restart the worker on the server, so it's a bit different. If for some reasons you mean that your worker crashes, i.e. stops on the production that you have to restart it manually again - then yes, you need that supervisor that will restart the worker for you. But the problems you described relates to different things if I understand you correctly.

Cheers!

Yeah that's a good question, I'm hot sure but probably this link https://github.com/alexsilv... will help you, but I think you already saw this link. Unfortunately I can't advise you some real production example for windows, also there is not so many windows servers, that's why there is not so many solutions for it!

Cheers! Hope it will help!

Hey Chad,

Unfortunately, I have not run it personally. Though it looks like there's some solutions around the internet, e.g.: https://gist.github.com/vra...

I hope this helps!

Cheers!

Thanks, this is one of the articles I used to get things going.

Hey Chad,

Ah, great! Sorry, can't say something more about it, have never done it before. Probably someone who use it could suggest you a good tip about it.

Cheers!

the following .ebextension config file is working to install supervisor and start messenger:consume, but the .env file is required to be populated with all the database credentials and such

      supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

      [supervisorctl]

Hey Chad,

Thank you for sharing this solution with others! I'm glad you were able to get it working.

Cheers!

Hey Ajie62!

Hmm. Try this command to see what's going on:

supervisorctl -c /usr/local/etc/supervisord.ini start

I definitely don't like that "no matches found". Also try using the stop command to see if it stops anything. Here's a screenshot of what starting and stopping looks on my machine - you can see how "start" sometimes doesn't have any output (if it's already started) but sometimes does.

Also, the zsh: no matches found: messenger-consume:* is odd... the error should come from supervisorctl... not from "zsh". Try surrounding messenger-consume:* with quotes. I don't know zsh well... but I'm wondering if it's somehow interpreting something differently...

Cheers!

Hey, thanks for you answer! The problem was oh-my-zsh. I removed it an now everything works fine. I assume I could have solved the problem and keep oh-my-zsh, but I wanted to save time and keep learning :) Thank you again, weaverryan
