Issue with Multiple Concurrent Laravel API Requests via cURL on Nginx in Laragon.

When making multiple concurrent API requests using cURL on Nginx in Laragon, you might encounter some issues. These issues can be due to various reasons such as insufficient resources, incorrect configuration, or conflicts between requests. In this answer, we will discuss some common issues and their solutions.

1. Timeout issues: When making multiple concurrent requests, the server might not be able to handle all the requests at once, leading to timeouts. To solve this issue, you can increase the maximum number of requests that can be handled at a time by Laravel and Nginx.

In Laravel, you can increase the maximum number of requests by setting the following value in your .env file:

BROADCAST_DRIVER=pusher
BROADCAST_PUSHER_APP_ID=your_app_id
BROADCAST_PUSHER_KEY=your_pusher_key
BROADCAST_PUSHER_SECRET=your_pusher_secret
BROADCAST_PUSHER_OPTIONS={"cluster":"mt1","encrypted":true,"host":"localhost:8001","port":8001,"scheme":"http"}
QUEUE_CONNECTION=sync
QUEUE_DRIVER=database

In Nginx, you can increase the number of worker processes by editing the nginx.conf file and adding the following lines:

worker_processes  4;

2. Connection issues: When making multiple concurrent requests, you might encounter connection issues, such as refused connections or connection timeouts. To solve this issue, you can increase the maximum number of connections that can be established at a time by Laravel and Nginx.

In Laravel, you can increase the maximum number of connections by setting the following value in your .env file:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_database_username
DB_PASSWORD=your_database_password
DB_CHARSET=utf8mb4
DB_COLLATION=utf8mb4_unicode_ci
DB_QUEUES=database

In Nginx, you can increase the maximum number of connections by editing the nginx.conf file and adding the following lines:

worker_rlimit_nofile 1024;

3. Conflict issues: When making multiple concurrent requests, you might encounter conflict issues, such as race conditions or deadlocks. To solve this issue, you can use Laravel's built-in queue system to process requests asynchronously and avoid conflicts.

In Laravel, you can use the queue system by setting the following value in your .env file:

QUEUE_CONNECTION=redis
QUEUE_DRIVER=database
BROADCAST_DRIVER=pusher

And then, install and configure Redis as your queue driver.

In conclusion, when making multiple concurrent API requests using cURL on Nginx in Laragon, you might encounter various issues, such as timeout issues, connection issues, or conflict issues. To solve these issues, you can increase the maximum number of requests and connections, use Laravel's built-in queue system, and configure Nginx and Laravel correctly.
