Process campaigns using Redis Queue.

[Michael Wilding]

Yeah that's installed.

 

[Rob]

That error is to do with resque which is a yii library in MW, @twisted1919 can you help out?

 

[Michael Wilding]

While we're waiting for @twisted1919, @Rob do you know whether I'm okay to leave the server set to send using the Redis queue?

I'm assuming not because although the test emails we're doing are showing as having been sent, we're not receiving them so I assume they're sitting in a Redis queue and not being processed because the daemon isn't running?

 

[Rob]

Sorry bud I was out. You won't be able to use the queue without the daemon running as you say. Did you try starting with debug

/usr/bin/php -q /absolute/path/to/apps/console/console.php queue --workers=10 --interval=5 --verbose=1

 

[Michael Wilding]

Debug is what I've been trying to run in with the same issue

 

[Rob]

Ah OK, one thing I did find was that I couldn't get it to run with PHP 5.5.9 so I upgraded to PHP 5.6. I don't know if it's all 5.5 versions but you might want to look at it if you are using that version.

 

[Michael Wilding]

Ah that could be it. I will look at getting that upgraded.

 

[Michael Wilding]

Upgraded to 5.6 but still getting:
Could not fork worker 0

 

[Rob]

Do you get anything if you run this
ps aux | grep queue

 

[Rob]

Just had a thought, do you have pcntl enabled in php-cli? I removed everything from disable_functions there are some peculiarities to pcntl on ubuntu in particular http://stackoverflow.com/questions/14096130/enable-pcntl-in-ubuntu-php-test-fails

Yes, if I do that I get:

[Michael Wilding]

Shall check for PCNTL

 

[Michael Wilding]

Thanks Rob enabling that seems to have resolved the issue

 

[Rob]

Brilliant, I really should have remembered that. sorry fella.

 

[Michael Wilding]

Thanks for all the help. I'm still having difficulties with the Redis queue. Everything seems to just get stuck in pending and never sent when I use it. Looks like I'll need to get one of you guys to set it up correctly for me at some point, does anybody offer that?

In the meantime normal send is actually going pretty fast.

 

[Rob]

Are the emails actually being sent to redis and then not being picked up for sending or are they not reaching redis at all?

 

[Michael Wilding]

Pretty sure it's not even sending to Redis tbh.

 

[Rob]

You can see if the worker queues were setup with redis-cli monitor:
redis-cli monitor
http://redis.io/commands/monitor

If the queues were created you should see something similar to:

"LPOP" "fac7b0bae8:queue:emails-queue"

You can also use www.redsmin.com for free for one redis server which will give you a GUI into what is happening on your redis server.

Thanks Rob, I'll take a look at it.
