Redis sessions, cache & queues

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

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.

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.

Hari

luceos I want to show cache pages to logged out users and spiders.

Can I just go with redis cache without the quee and sessions? Will that requires daemon setup?

Hari

luceos

edit : its working now - it happened due to cloudflare cache

edit2:

if i do not want queues i don't need deamon and need not to maintain anything right?

Hari

sanwhere 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.

if you are a non-techqnical person ignore that step. (i have ignored) just go with below mentioned setup

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

luceos

Hari sessions and cache work perfectly fine without the queue. Make sure to use disable('queue') in your extend.php:

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

Hari

luceos after updating this website is showing 500 error

rafaucau i do have access but its hard for me to setup daemon

Hari

luceos unable to enable DB queues extension, do you think it is because I'm using MySQL 5.6?

Edit : for now I want to try againRedis queue using corn job like mentioned here rafaucau

I will keep you posted. thanks for responding. 🌼

rafaucau

Hari If it is possible to set up a cron on your hosting that allows you to run tasks without a timeout. Then you can use the method I mentioned earlier: rafaucau

This script checks if the queue process is running, if not, it starts it. This way, when the process crashes, cron will restart it.
I use it on my forum because I don't have the possibility to manage processes there.

I think that if you have such a possibility on your hosting, it is better to use Redis queue than the database queue because of better performance.

Hari

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.

#set -x

I've tried to update the same at the advanced corn job area but it is showing some error, I think we need to modify it for my need 😊 could you please help me? my forum is in the subdirectory

luceos

Hari any errors in storage/logs?

luceos

Hari if i do not want queues i don't need deamon

Correct. I can't answer the second question.

sanwhere

Hari I am a technical person, I have a server and I am taking care of it. I would like to add it, otherwise it does not make any sense as @luceos said:

If you don't take care of this step, pending jobs will pile up without being processed.

Braden

@luceos

I tried to install it on flarum 15 using composer require blomstra/flarum-redis: ^ 0.2.4-beta
It installed successfully
Then i went inside public_html/vendor/blomstra/flarum-redis/extend.php

i updated it like this

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

I activated it in admin panel and
then i run php flarum queue:work which i got this response There are no commands defined in the "queue" namespace.

I Ignored, and tried to surf my site but then it had already broken showing the HTTP/Server message. 😓

Inside storage/cache there were many folders populated

Maybe am missing something?

My flarum speed grade score is C. I want to make this one work and score A like @[deleted]

sanwhere

Braden I guess extend.php needs to be in flarum folder, not in blomstra folder.

Braden

sanwhere after reinstalling it again and adding the code to flarum folder which is in public_html

I encountered HTTP ERROR 500

php flarum cache:clear and php flarum queue:work (became silent after http 500 error)
