The following is part 1 of a 4 part series that will go over an installation and configuration of Pacemaker, Corosync, Apache, DRBD and a VMware STONITH agent.
The aim here is to build an active/passive Pacemaker cluster with Apache and DRBD. Continue reading
We will be setting up a load balancer with Heartbeat and Ldirector on CentOS 6. Continue reading
We will be setting up a load balancer using two main technologies to monitor cluster members and cluster services: Keepalived and HAProxy. Keepalived uses LVS to perform load balancing and failover tasks on active and passive LVS routers, while HAProxy performs load balancing and high-availability services to TCP and HTTP applications. Continue reading
Article is heavily based on the previous one about Setting Up a Load-Balancing LVS (NAT) Cluster with Piranha, but this one aims to show how to configure an LVS cluster with direct routing rather than NAT.
Linux Virtual Server (LVS) system offers a highly-available and scalable solution for production services using specialised routing and load-balancing techniques that can be configured through the Piranha configuration tool. Continue reading
High-availability clusters (also known as HA clusters or fail over clusters) are groups of computers that support server applications that can be reliably utilised with a minimum of down-time. Continue reading
Installing VirtualBox on a headless Debian server and setting up a Ubuntu 12.04 guest operating system. Continue reading
Nessus is a cross-platform, comprehensive systems vulnerability scanner, which provides a wide range of penetration techniques starting with a simple host ping scan and finishing with dangerous Denial of Service attack. Continue reading
Ntop is a network monitoring tool similar to Unix top, which shows network traffic usage. It can act as a NetFlow collector for flows generated by routers such as Cisco or Mikrotik. NetFlow is an industry standard for flow-based traffic monitoring. Continue reading
