How to setup HAProxy as Load Balancer for MariaDB on CentOS 7
Author: Muhammad Arul •
Tags: centos, high-availability, linux, mysql •
Comments: 10 In this tutorial, I will guide you trough the installation of a MariaDB Galera cluster on CentOS 7 which has an HAProxy load balancer in front. The total setup consists of 4 servers. I will use 3 CentOS 7 servers for the database nodes, 2 nodes will be active and 1 acts as the backup node. The fourth server will be used for the HAProxy load balancer. For the balance algorithm, we use leastconn (but you can use other algorithms).

How to setup HAProxy as Load Balancer for Nginx on CentOS 7
Author: Muhammad Arul •
Tags: centos, high-availability, linux, nginx, server •
Comments: 14 HAProxy or High Availability Proxy is an open source TCP and HTTP load balancer and proxy server software. In this tutorial, I will guide you trough the HAProxy installation and configuration for 3 servers, one load balancer, and two Nginx web servers. We will install HAProxy on a single server and then install Nginx web server on the other servers. HAProxy acts as a load balancer for the Nginx web servers.

High-Availability Storage with GlusterFS on Debian 8 - Mirror across two storage servers
Author: Till Brehm •
Tags: debian, high-availability, linux, server, storage •
Comments: 12 This tutorial shows how to set up a high-availability storage with two storage servers (Debian Jessie) that uses GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage nodes. The client system (Debian 8 as well) will be able to access the storage as if it was a local filesystem.

Setting up Master-Master Replication with MySQL on Debian 8 (Jessie)
Author: Till Brehm •
Tags: debian, high-availability, mysql •
Comments: 10 This tutorial describes a replicated MySQL setup (Mater/Master replication) with 2 nodes where data can be read and written to both nodes at the same time. MySQL takes care to replicate the data to the other node and ensures that primary auto increment keys don't collide.

Setting up Unison File Synchronization between two Servers on Debian 8 (Jessie)
Author: Till Brehm •
Tags: debian, high-availability, server, storage •
Comments: 10 This tutorial shows how to set up file synchronization between two Debian 8 servers with Unison. Unison is a file-synchronization tool similar to rsync, the big difference is that it tracks/synchronizes changes in both directions, i.e., files changed on Server 1 will be replicated to Server 2 and vice versa.

How To Set Up A Load-Balanced MySQL Cluster With MySQL 5.1
Author: petero • Tags: mysql, debian, high-availability • Comments: 6How To Set Up A Load-Balanced MySQL Cluster With MySQL 5.1 This tutorial is based on Falko Timme's tutorial for MySQL Cluster 5.0. It shows how to configure a MySQL 5.1 cluster with five nodes: 1 x management, 2 x storage nodes and 2 x balancer nodes. This cluster is load-balanced by an Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

High-Availability Storage With GlusterFS 3.2.x On Debian Wheezy - Automatic File Replication (Mirror) Across Two Storage Servers
Author: Falko Timme •
Tags: debian, high-availability, storage •
Comments: 4 This tutorial shows how to set up a high-availability storage with two storage servers (Debian Wheezy) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Debian Wheezy as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10
Author: Falko Timme •
Tags: high-availability, storage, ubuntu •
Comments: 0 This tutorial shows how to combine four single storage servers (running Ubuntu 12.10) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (Ubuntu 12.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.
