Creating An NFS-Like Standalone Storage Server With GlusterFS On Ubuntu 10.04
This tutorial shows how to set up a standalone storage server on Ubuntu 10.04. Instead of NFS, I will use GlusterFS here. The client system 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.

How To Set Up MySQL Database Replication With SSL Encryption On Debian Lenny
This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures though.

Apache has always been the web server of choice for me. It is a real beast when it comes to resources usage specially in a resource limited environment such as a VPS. I started playing with Nginx a lightweight, high performance web server. My area of interest was running Nginx as a reverse proxy and making it work in a Apache/ISPConfig 3 environment.
14.05.10: The Perfect Subversion Server - Debian Lenny [ISPConfig3]
|
The Perfect Subversion Server - Debian Lenny [ISPConfig3]
Subversion is a free/open-source version control system. That is, Subversion manages files and directories, and the changes made to them, over time. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of "time machine". This guide will help you setup the subversion system, and integrate it with your existing ISPConfig3 installation allowing you control over disk usage, quota and other factors in a very familiar way. Perhaps one day, somebody can use this process to create a plug in for ISPConfig3 that does all of this automatically.

High-Availability Storage With GlusterFS On Mandriva 2010.0 - Automatic File Replication (Mirror) Across Two Storage Servers
This tutorial shows how to set up a high-availability storage with two storage servers (Mandriva 2010.0) 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 (Mandriva 2010.0 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.

By setting up daily reporting, this notifies you within, at most, 24 hours of when any file was changed, added, or removed. It also helps establish an audit trail in the event your site is compromised. These instructions are designed for an end user, where you don't need to have root access, to implement and assumes your server has the aide binary installed. Most hosts will have this installed already, or will install it for you upon request.

Flexnet License Monitoring With rrdtool
Some of you may know the commercial Flexnet Licencing Application (©Macrovision). It's a client-server based solution for managing the usage of socalled Flexnet-enabled applications. You can hold licenses of more than one product on one license-server. As you typically have to buy licenses and licenses can be expensive it would be nice to have a monitoring solution, to see the utilization of the precious licenses, wether they are underutilized (so money is wasted) or are always fully utilized (so that you can suspect that sometimes people can not do their work, or only delayed) which is also a waste of resources. As far as I know there are commercial applications for performing such reports, but again you have to spent money. Why not build a simple system yourself, which shows the actual and past usage in an "MRTG style"?
