  • Creating A Local Yum Repository (CentOS)
    Sometimes it can be handy to set up your own repository to prevent from downloading the remote repository over and over again. This tutorial shows how to create a CentOS mirror for your local network. If you have to install multiple systems in your local network then all needed packages can be downloaded over the fast LAN connection, thus saving your internet bandwidth.

  • Entering A Safe Mirror When Logging In With Unionfs And Chroot
    When reading a hint on the website of LinuxFromScratch I discovered the special capabilities of unionfs, specially in combination with chroot. Later I read a HowTo on a wikiwebsite of Gentoo, about entering a chrooted home directory when using a special script as shell. Combining these two brings me to using a chrooted environment, which you enter when logging in as a special user. This environment is an exact copy (mirror) of the system you are working on. Because you are in safe copy of the real system, you can do whatever you like, it will never change the system, everything stays inside the cache (the readwrite branch).

  • High-Availability Storage With GlusterFS 3.2.x On Debian Wheezy -Automatic File Replication (Mirror) Across Two Storage Servers
    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 A Web, Email And MySQL Database Cluster (Mirror) On Debian 5.0 With ISPConfig 3
    This tutorial describes the installation of a clustered web, email, database and DNS server to be used for redundancy, high availability and load balancing on Debian 5 with the ISPConfig 3 control panel. GlusterFS will be used to mirror the data between the servers and ISPConfig for mirroring the configuration files. I will use a setup of two servers here for demonstration purposes but the setup can scale to a higher number of servers with only minor modifications in the GlusterFS configuration files.
