[Solved] Apache 2.4.62 - AH00534: httpd: Configuration error: More than one MPM loaded.

 If you are building Apache/httpd from source (in my case it is httpd 2.4.62) and you encounter this error: AH00534: httpd: Configuration error: More than one MPM loaded. But you are absolutely sure that in your config file you just enable 1 module, here is what you need to check: In my case, my command of building Apache from source is this: ./configure --prefix=/usr/local/httpd-2.4.62 \ --enable-proxy \ --enable-proxy-http \ --enable-proxy-ajp \ --enable-forward \ --enable-module=most \ --enable-mods-shared=all \ --enable-so \ --enable-include \ --enable-headers \ --enable-deflate \ --enable-cache \ --enable-disk-cache \ --enable-mem-cache \ --enable-rewrite \ --enable-static-support \ --enable-expires \ --with-apr-util=/usr/local/apr \ --with-apr=/usr/local/apr Important: If you run httpd -M, you will see that mpm-event is "static", which means it is compiled as "static" module, i.e. pre-build and loaded by default. But if you add: --enable-mpms-shared \ --with-m

 Quick note: If you are serving HTML/CSS/JS/Any image files via AWS S3 with Cloudfront, but got 503 error, here is one way to solve: Simply put: In Viewer request, set cloudfront function to "serve-html-by-s3" Set Viewer repsonse to "No association" Setting Viewer response to value other than "No association" will result in 503 error.

PHP 5.6 way to send AWS SNS topic message

This is an example PHP 5.6 script to send AWS SNS topic message. The architecture and assumption are as follow: Architecture: SNS (FIFO) -> SQS(FIFO) -> Lambda Only FIFO SNS can connect to FIFO SQS. Standard SNS cannot publish to FIFO SQS. Assumption: This script is executed in an EC2 instance. Assigned an AWS role to send SNS message. Because of above, supposed that there is no need to use Credential when creating SnsClient object. As the OS and PHP in this EC2 is old, the curl is already outdated. So it set http to false to bypass SSL verification.  Reference here . The $message part is designed for sending email for different vendor. In other words, it would vary in different case. Since SNS and SQS are FIFO, MessageGroupId must be set. It can be any random string, which is used to group message together for sending purpose. Here is the code <?php  require_once 'vendor/autoload.php'; use Aws\Sns\SnsClient; try{     $snsClient = new SnsClient([         '

Laravel 11 cannot connect to Redis (serverless) - Checking points

Image
 If you are having trouble connecting to Redis server (usually AWS, other cloud platform applied as well), here are some of my tested ideas to check. All points are valid as of this writing, under Laravel 11 (Using Nginx + php-fpm, all dockerize), and build/executed in AWS ECS As of this writing(5 Jul 2024), please use REDIS_CLIENT = phpredis.  predis did not work.  It will not able to connect to your AWS redis (serverless) server.  Yet it works if you setup in your local development In my setting, REDIS_CLUSTER = rediss (double s), before that default value is `redis` There are 3 array sections: default, cache and session default: according to this git comment , this is for "normal" server.  I guess it means standalone server.  Which means the settings under default is for normal server. cache: These settings are for cluster.  I found that serverless = cluster. session: These settings are for sessions, if you are saving session data in redis In other words, you cannot assume
