Linux clustering options

 Linux Clustering Options

Linux clustering is a method of linking multiple servers together to form a single, cohesive system. This allows for increased performance, reliability, and scalability, as well as the ability to easily add or remove resources as needed.

There are several different solutions available for Linux clustering, each with their own strengths and weaknesses. Some of the most popular options include:

  1. OpenMPI: OpenMPI is an open-source implementation of the Message Passing Interface (MPI) standard, which is commonly used for high-performance computing. OpenMPI is highly configurable and supports a wide range of platforms and interconnects.

     

  2. Rocks Cluster: Rocks Cluster is a Linux distribution specifically designed for cluster computing. It provides a comprehensive set of tools and utilities for cluster management, as well as a user-friendly web-based interface.

     

  3. LSF: LSF is a commercial workload management solution that allows users to easily manage and schedule jobs on a cluster. It also provides a suite of tools for monitoring, reporting, and troubleshooting.

     

  4. OpenHPC: OpenHPC is an open-source framework for building high-performance computing clusters. It provides a comprehensive set of tools and libraries for building, configuring, and managing clusters, as well as a user-friendly web-based interface.

     

  5. Kubernetes: Kubernetes is a popular open-source container orchestration system that can be used to manage and scale clusters of containers.
    6. Pacemaker. It is an open-source cluster resource manager that is widely used in enterprise environments. It provides a high-availability solution by managing the resources of a cluster and ensuring that they are always available, even in the event of a failure. Pacemaker works by monitoring the resources of a cluster, and if a failure occurs, it will automatically take action to bring the resource back online.

6. GlusterFS: GlusterFS is a distributed file system that allows users to create a single, unified file system across multiple servers. GlusterFS is highly scalable and can be used to create a cluster of servers that can handle large amounts of data. It also provides a high-availability solution by automatically replicating data across multiple servers, ensuring that data is always available.

7. Corosync and Heartbeat are also widely used solutions for Linux clustering. Corosync is a messaging and membership framework that is used to implement high-availability clusters. It provides a reliable, fault-tolerant messaging layer that is essential for maintaining communication between cluster nodes. Heartbeat is a simple and lightweight cluster resource manager that can be used to monitor the status of cluster resources and take action if a failure occurs.

8. Lastly, Grid Engine is another option for Linux clustering. It is a open-source batch-queuing system for distributed resource management. it is designed to manage and schedule jobs on large clusters, it supports a wide range of platforms and is highly configurable, allowing users to easily adapt it to their specific needs.

In conclusion, Linux clustering solutions offer a range of features and capabilities that can be used to increase the performance, reliability, and scalability of systems. Whether you are looking for a simple, lightweight solution or a more comprehensive, enterprise-grade solution, there is a Linux clustering solution that can meet your needs.

Manual Kubernetes TLS certificate renewal procedure

Intro Kubernetes utilizes TLS certificates to secure different levels of internal and external cluster communication.  This includes internal services like the apiserver, kubelet, scheduler and controller-manager etc. These TLS certificates are created during the initial cluster installation and are usually valid for 12 months. The cluster internal certificate authority (CA) certificate is valid for ten years. There are options available to automate certificate renewals, but they are not always utilised and these certs can become out of date. Updating certain certificates may require restarts of K8s components, which may not be fully automated either. If any of these certificates is outdated or expired, it will stop parts or all of your cluster from functioning correctly. Obviously this scenario should be avoided - especially in production environments. This blog entry focuses on manual renewals / re-creation of Kubernetes certificates. For example, the api-server certificate below exp

Deprecating Networking Ingress API version in Kubernetes 1.22

  Intro Kubernetes deprecates API versions over time. Usually this affects alpha and beta versions and only requires changing the apiVersion: line in your resource file to make it work. However with this Ingress object version change, additional changes are necessary. Basics For this post I am quickly creating a new cluster via Kind (Kubernetes in Docker) . Once done, we can see which API versions are supported by this cluster (version v1.21.1). $ kubectl api-versions | grep networking networking.k8s.io/v1 networking.k8s.io/v1beta1 Kubernetes automatically converts existing resources internally into different supported API versions. So if we create a new Ingress object with version v1beta1 on a recent cluster version, you will receive a deprecation warning - and the same Ingress object will exist both in version v1beta1 and v1. Create $ cat ingress_beta.yaml apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata:   name: clusterpirate-ingress spec:   rules:   - http:       path

Analysing and replaying MySQL database queries using tcpdump

Why There are situations where you want to quickly enable query logging on a MySQL Database or trouble shoot queries hitting the Database server in real-time. Yes, you can enable the DB query log and there are other options available, however the script below has helped me in many cases as it is non intrusive and does not require changing the DB server, state or configuration in any way. Limitations The following only works if the DB traffic is not encrypted (no SSL/TLS transport enabled). Also this needs to be run directly on the DB server host (as root / admin). Please also be aware that this should be done on servers and data you own only. Script This script has been amended to suit my individual requirements. #!/bin/sh tcpdump -i any -s 0 -l -w - dst port 3306 | strings | perl -e ' while(<>) { chomp; next if /^[^ ]+[ ]*$/;   if(/^(ALTER|COMMIT|CREATE|DELETE|DROP|INSERT|SELECT|SET|UPDATE|ROLLBACK)/i) {     if (defined $q) { print "$q\n"; }     $q=$_;   } else {
