This package is for Laravel 5 and removes all jobs from a queue using the Redis driver. Because Laravel Horizon uses Redis for its queues, this tool can be used to clear your Horizon jobs. If you are using Horizon, it may be best to have a separate Redis connection for your jobs and another for other parts of your application.
You can install this Laravel package using Composer by running the following command. The configuration is normally set to default. The horizon feature here is not fool proof so you will want to check on the results after the fact.

It seems that using several workers php artisan queue:work --daemon I have 10 workers in my case, that download a file from an FTP server, save the file itself locally, inserts a row in a database and then delete the original file from the FTP site. I've experienced several times now, that several rows appear in the database, and sometimes I get an error informing me that the file on the FTP site doesn't exist but the row appears in the database meaning that it has already been processed.
FYI, I've temporarily reduced the number of workers to 1 and I haven't had a user error since, altho I do still get the Predis errors. I've tried to reproduce this locally but cannot, it seems that it works as expected. I don't get the Predis error either. The only difference is that I'm using supervisor in production and 10 terminals on my Mac Also, the author of redis is working on a dedicated message queue system for Redis, Disque.
In case of multiple hosts, I would not advise to use beanstalkd as if one machine goes down, you would loose all your jobs on that machine. Maybe implementing a lock algorithm in the RedisQueue. If it's related to redis then it should be mentioned in the docs that multiple workers can not be run when the queue driver has been set to redis. I have a thread in Laracasts that explain why this happen, how to avoid it and a lot of information about how Laravel handles Queues since I had to dig the source code a lot to understand how it works.
I knew it was going to be todo with Laravel's implementation and not Redis itself. I think I did actually set the expire time to 0 or null and still encountered the issue.
I'm quite astounded that this has been closed though as it's definitely a bug within Laravel and at the very least should be mentioned in the documentation. So with it set to 0, virtually all jobs will be able to duplicate any job that takes more than 0 secondsbut this depends on the amount of jobs and workers running.
I agree with GrahamCampbellthis is not a bug. I was also wondering why laravel was not using rpoplpush when I was working on port laravel redisqueue to symfony, since in redis documentation it was supposed to use for a reliable queue. I would also be curious to know the values you are using for sleep and timeout on your queue worker configuration.
It is particular to the Redis driver. I have been using beanstalkd ever since with no issue.We can simply send email in Laravel. But in this tutorial we will see how we can send email via Laravel Queue with redis connection and monitor our failed job via Laravel Horizon. Horizon will be bonus for you in this tutorial.
Now lets start our Laravel Horizon and Queue tutorial. I will explain step by step to complete this laravel queue series. You have to just follow this below step. I will start from scratch. So we have to download fresh laravel 7 app. To download it, run below command. To complete this tutorial i will use Order model. So we need some order to create laravel queue tutorial.
For this reason i need factory also to insert some dummy data quickly. After running this command we will get orders migration file and OrderFactory. So open both file and paste it. In this we need to add some dummy records to create laravel queue tutorial.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I have a production laravel application and the staging application running on the same server. I am running redis, which I am using as my queue driver.1. Laravel Horizon - Monitor Redis Queue Jobs
They are obviously connected to different databases. The question is if jobs that are pushed onto the reds queue from the staging application will interfere with the production db and vice versa. You can set the prefix Laravel uses for the Redis cache. You could leave the main one as laravel and set your staging app prefix to stage or something. This will mean multiple Laravel apps can use the same Redis instance.
In addition to the default hostportdatabaseand password server configuration options, Predis supports additional connection parameters that may be defined for each of your Redis servers.

AndrewMcLagan is right. I'm still searching for a solution myself. See Ryan's answer if anyone's still looking for a solution. It works for me - tested using php artisan queue:listen and php artisan tinker to dispatch a test job. I had this same problem, and it took me hours to find the solution.

Tales from documentation: Write for your dumbest user. Upcoming Events.Queues allow you to defer the processing of a time consuming task, such as sending an email, until a later time.
Deferring these time consuming tasks drastically speeds up web requests to your application. In this file you will find connection configurations for each of the queue drivers that are included with the framework, which includes a database, BeanstalkdAmazon SQSRedisand a synchronous driver that will execute jobs immediately for local use.
A null queue driver is also included which simply discards queued jobs. Before getting started with Laravel queues, it is important to understand the distinction between "connections" and "queues". However, any given queue connection may have multiple "queues" which may be thought of as different stacks or piles of queued jobs.
Note that each connection configuration example in the queue configuration file contains a queue attribute. This is the default queue that jobs will be dispatched to when they are sent to a given connection. In other words, if you dispatch a job without explicitly defining which queue it should be dispatched to, the job will be placed on the queue that is defined in the queue attribute of the connection configuration:.
Some applications may not need to ever push jobs onto multiple queues, instead preferring to have one simple queue. However, pushing jobs to multiple queues can be especially useful for applications that wish to prioritize or segment how jobs are processed, since the Laravel queue worker allows you to specify which queues it should process by priority.
For example, if you push jobs to a high queue, you may run a worker that gives them higher processing priority:.
In order to use the database queue driver, you will need a database table to hold the jobs. To generate a migration that creates this table, run the queue:table Artisan command. Once the migration has been created, you may migrate your database using the migrate command:.
If your Redis queue connection uses a Redis Cluster, your queue names must contain a key hash tag. This is required in order to ensure all of the Redis keys for a given queue are placed into the same hash slot:.
You may generate a new queued job using the Artisan CLI:. Job classes are very simple, normally containing only a handle method which is called when the job is processed by the queue. To get started, let's take a look at an example job class. In this example, we'll pretend we manage a podcast publishing service and need to process the uploaded podcast files before they are published:.
In this example, note that we were able to pass an Eloquent model directly into the queued job's constructor. Because of the SerializesModels trait that the job is using, Eloquent models will be gracefully serialized and unserialized when the job is processing. If your queued job accepts an Eloquent model in its constructor, only the identifier for the model will be serialized onto the queue.
When the job is actually handled, the queue system will automatically re-retrieve the full model instance from the database. It's all totally transparent to your application and prevents issues that can arise from serializing full Eloquent model instances. The handle method is called when the job is processed by the queue. Note that we are able to type-hint dependencies on the handle method of the job. The Laravel service container automatically injects these dependencies.
Otherwise, the job may not properly serialize to JSON when being placed on the queue.To run my redis queue, I've made a Linux service script that runs this command:. Usually I use it to process a email notification system, but now I need to use the queue system to process some command line functions and I want to use a separate queue.
I'm kinda new in queues and I couldn't find any information about how can I create multiple queues for the same connection. Instead, I've found people using different connections for each different queue. This is something that is missing in laravel documentation and I cannot find out another solution. It seems weird to me if I have to configure the same connection multiple times with different names in the connection name and queue. Cannot I use an array in the queue parameter for a connection?

Want us to email you occasionally with Laracasts news?Redis is an open source, advanced key-value store.
It is often referred to as a data structure server since keys can contain stringshasheslistssetsand sorted sets. The extension is more complex to install but may yield better performance for applications that make heavy use of Redis. Within this file, you will see a redis array containing the Redis servers utilized by your application:.
The default server configuration should suffice for development. However, you are free to modify this array based on your environment. Each Redis server defined in your configuration file is required to have a name, host, and port. If your application is utilizing a cluster of Redis servers, you should define these clusters within a clusters key of your Redis configuration:. By default, clusters will perform client-side sharding across your nodes, allowing you to pool nodes and create a large amount of available RAM.
However, note that client-side sharding does not handle failover; therefore, is primarily suited for cached data that is available from another primary data store. If you would like to use native Redis clustering, you should specify this in the options key of your Redis configuration:.
Laravel Queues Example Using Redis and Horizon
In addition to the default hostportdatabaseand password server configuration options, Predis supports additional connection parameters that may be defined for each of your Redis servers. If you plan to use PhpRedis extension along with the Redis Facade alias, you should rename it to something else, like RedisManagerto avoid a collision with the Redis class.
You can do that in the aliases section of your app. Generally, you should remove this alias entirely and only reference the facade by its fully qualified class name while using the Redis PHP extension. You may interact with Redis by calling various methods on the Redis facade.
The Redis facade supports dynamic methods, meaning you may call any Redis command on the facade and the command will be passed directly to Redis. As mentioned above, you may call any of the Redis commands on the Redis facade. Laravel uses magic methods to pass the commands to the Redis server, so pass the arguments the Redis command expects:. Alternatively, you may also pass commands to the server using the command method, which accepts the name of the command as its first argument, and an array of values as its second argument:.
This will give you an instance of the default Redis server. You may also pass the connection or cluster name to the connection method to get a specific server or cluster as defined in your Redis configuration:. Pipelining should be used when you need to send many commands to the server.
The pipeline method accepts one argument: a Closure that receives a Redis instance. You may issue all of your commands to this Redis instance and they will all be streamed to the server thus providing better performance:. Laravel provides a convenient interface to the Redis publish and subscribe commands. These Redis commands allow you to listen for messages on a given "channel". You may publish messages to the channel from another application, or even using another programming language, allowing easy communication between applications and processes.
First, let's setup a channel listener using the subscribe method. We'll place this method call within an Artisan command since calling the subscribe method begins a long-running process:. Using the psubscribe method, you may subscribe to a wildcard channel, which may be useful for catching all messages on all channels.
