  • Setting up Unison File Synchronization between two Servers on Debian 8 (Jessie)

    debian Author: Till BrehmTags: , , , Comments: 5

    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: peteroTags: , , Comments: 6

    How 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

    debian Author: Falko TimmeTags: , , 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.

    Installing The Galera-Iworx Cluster This document describes the installation of the Galera/Interworx cluster. This cluster provides the default Load Balancing that is available within Interworx, and additionally MySQL loadbalancing through MySQL Galera Clustering.

  • High Availability NFS With DRBD + Heartbeat

    Author: rbabchisTags: , Comments: 1

    High Availability NFS With DRBD + Heartbeat This document describes information collected during research and development of a clustered DRBD NFS solution. This project had two purposes: HA NFS solution for Media-X Inc.; develop a standard tool kit and documentation that Win2ix can use for future projects.

  • Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10

    ubuntu Author: Falko TimmeTags: , , 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.
