Does RHEL require the use of RedHat JBoss A-MQ or can standard AMQ run on RHEL?
There is nothing in the RHEL license that requires you to use their solutions. We use ActiveMQ on RHEL in production all of the time.

I want to install ActiveMQ on Windows Server 2022 for my production. Does ActiveMQ support Windows Server 2022?
Apache ActiveMQ is a Java application so as long as your platform has a Java Virtual Machine (i.e. JVM) then it can run Apache ActiveMQ. The latest versions of Apache ActiveMQ require Java 11 although there are still fairly recent versions that support Java 8. Download links are:
ActiveMQ "Classic"
ActiveMQ Artemis
I have Virtualmin installed on my CentOS7 server and few websites are currently running on this server. There's no separate Apache installation because it is using Virtualmin. However I need to install / enable HTTP/2 on my server but current resources on the internet are not helpful enough to learn how to do this since I have a Virtualmin installation on which few sites are hosted. How can I do this?
HTTP/2 support was only added with Apache 2.4.17, therefore the only way to make it work on CentOS 7 is to rebuild it manually. OpenSSL version 1.0.2 is already available with CentOS 7 though.
Perhaps the easiest way would be is to upgrade to the distro that already ships needed version of Apache.
I cannot recommend CentOS 8 due to recent events, however Ubuntu 20.04 LTS and Debian 10 are both supported with Virtualmin and have latest versions of Apache. In the future we will support any 1:1 compatible forks/clones of RHEL; recently we fixed RHEL 8 support as well and CentOS 8 Stream is also supported.
I have a server with JBoss EAP 7 on port 8380.
I want to monitor the jboss via visualvm from my workstation.
How do I need to configure to accept the connection.
I tried it with jmx-parameters in $JAVA_OPTS and jmx over management-interface.
Nothing works.
Maybe someone has a good tutorial.
Best Regards

The upcoming JBoss EAP 7.1 Performance Tuning Guide has instructions that I have also tested with JBoss EAP 7.0 (I assume you are connecting to a remote server):
Bind the management interface to an IP address: https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.1/html-single/performance_tuning_guide/index#configuring_remote_monitoring
Connection steps for VisualVM: https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.1/html-single/performance_tuning_guide/index#connecting_to_a_remote_jboss_eap_jvm_using_visualvm
Full disclosure: I am a Red Hat employee and the writer of that guide. If you have any feedback to improve the guide, I'd be more than happy to receive it.
I want to use mod_proxy_wstunnel on my CentOS machine. So, I went through the documentation and it says that, this module is the part of Apache >= 2.4.5 but, I'm not able to use the Module and mod_proxy_wstunnel.so nowhere exists in my server.
I know, there are lots of related questions but those are all for older version of Apache.
Anyway, I'm using
Apache 2.4.18
CentOS 6.7 (Final)
You need to determine where yourour 2.4.18 build came from, because it's not contemporary / part of Centos 6.
Whoever built or packaged it it needs to perform the routine task if including an additional standard module.
Are there any issues in setting up Redis cluster on various platforms like windows , Mac or Solaris. Currently Redis website says there is support for these platforms but I just want to know is there any caveat in cluster deployment on these?
Redis cluster (i.e. v3) should be runnable on all supported platforms (i.e. *nix). The Windows version is not an official port but the last time I checked (now) it was still at v2.8 so I don't see how you could use the cluster with it.
The MSOpenTech windows port of Redis has released a beta version 3.0 supporting Redis cluster:
