Redis sessions, cache & queues

tuxmain

luceos Now it works! 🙂

rafaucau

luceos I finally have a configuration that works on my hosting:

 (new Blomstra\Redis\Extend\Redis([
       'scheme' => 'unix', 
       'path' => '/home/klient.dhosting.pl/androiddev/.redis/redis.sock',
       'port' => 0,
       'database' => 1
   ]))

In addition, it turned out after consulting with hosting support that at their site the connection to Redis does not work via SSH, which is why I have connection errors when php flarum cache:clear

luceos

rafaucau will add this to the faq, thanks!

qooba

rafaucau did you manage to use different database for each service on dhosting.pl

fakruzaruret

Will I need to install redis to server? Is this enough for using redis cache?

fakruzaruret

luceos To test the worker can start use php flarum queue:work.

I get his error

luceos

fakruzaruret looks like you need to enable some pcntl functions for php.

Hari

is this supported for v1.0.3? (flarum latest version)

Hari that's caused by the fact that this package is only tagged as a beta stability.

I just tagged 0.4.0 which is 0.4.0-beta.3 but stable. Feel free to give this another try in a couple of minutes (when composer/packagist caught up).

IanM

Hari I've just published 1.0.2 of glowingblue/redis-setup, please update to this version, and your problem should be resolved

1Dot

Can anyone tell me is sessions here means realtime updates like pusher??

luceos

1Dot no, in fact sessions means once you are logged in so that the server understands who you are.

1Dot please understand this is an advanced utility. You have to be able to manage your server. If you don't understand the instructions provided it's best to get professional help or alternatively rely on the glowingblue redis setup extension. In both cases basic understanding of installing and configuring services like redis are recommended.

1Dot

luceos null

Here I have to write database password??

luceos How do I configure a redis socket?

Unable to understand where to paste the below code?

Can anyone give me detailed steps in order to install, enable and use this,? as maybe it also requires installing redis in linux?

Hari

sanwhere this is not a extension , read first post (documentation) to configure correctly

luceos If you don't understand the instructions provided it's best to get professional help or alternatively rely on the glowingblue redis setup extension. In both cases basic understanding of installing and configuring services like redis are recommended.

sanwhere

I can't see the extension in admin panel. is this normal? 😕

sanwhere

Hari thanks, I figured it out. it is working now.

Hari

sanwhere i have installed this but did not setup

we just need to add to these lines to extend.php right?

return [
    new Blomstra\Redis\Extend\Redis([
        'host' => '127.0.0.1',
        'password' => null,
        'port' => 6379,
        'database' => 1,
    ])
];

luceos

Hari use different databases please. See the instructions.

sanwhere

Hari I used this code to make it work.

Hari I am getting same output, so it means it is working. I have 1 database.

luceos I didn't add this, I get the think, but how can I do that, can you give me an example or clue so I can dig it.

Hari

luceos i have added this in extend.php file

return [
    (new Blomstra\Redis\Extend\Redis([
        'host' => '127.0.0.1',
        'password' => null,
        'port' => 6379,
        'database' => 1,
    ]))
    ->useDatabaseWith('cache', 1)
    ->useDatabaseWith('queue', 2)
    ->useDatabaseWith('session', 3)
];

if i run this command php flarum queue:work

i am getting this result

[2021-07-11 07:56:00][qByowZ3FOKSbh28b6wNoaYkztHZE9hBK] Processing: Flarum\Notification\Job\SendNotificationsJob
[2021-07-11 07:56:00][qByowZ3FOKSbh28b6wNoaYkztHZE9hBK] Processed: Flarum\Notification\Job\SendNotificationsJob

does this mean its working?

luceos

Hari yes it is. Now you need to set the worker up as a daemon, using supervisor or systemd.

Hari

luceos sorry, i am not getting this step

so i need to install supervisor its an extension from larvel (server level) and need to configure it right?

https://laravel.com/docs/6.x/queues#supervisor-configuration

Edit: i don't have access, cloudways limit certain commands. its a long process to explain them regarding this. i will wait for GB setup

Hari

luceos instead of supervisor or systemd can we just use corn job?

i don't know this is the right question or not.

due to the limitations, I could not able to use supervisor for my custom php instance at cloudways.

luceos

Hari gb setup won't solve this. This step is required to have the queue process jobs in the background, unattended. To get this done it needs to run as a daemon, continuously and be restarted on failure. If you don't take care of this step, pending jobs will pile up without being processed.

rafaucau

If you don't have full access on the server because you have shared hosting, for example, then you can still use Redis Queue.
What I did was to set up a cron for such a script:

#set -x

queue=`ps -aux | grep "flarum queue:work" | grep -v grep`
if [[ -z $queue ]]; then
while true :
	do
		[[ -z $queue ]] && { php flarum queue:work; }
	done
else
exit 0
fi

When a process fails for some reason, cron will start it again.
