Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Centos 6.4 server with PHP5 support (through PHP-FPM) and MySQL support.

This tutorial shows how to set up a standalone storage server on CentOs 6.3. 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. read more...

This article explains how to set up (and monitor) an Active/Passive PostgreSQL Cluster, using Pacemaker with Corosync and DRBD. We use two nodes, one active (that answers requests from apps) and the other one in passive mode. If the active server is down, the passive one will automatically take its position (being the active node). We are using the CentOS 5.5 (64bits) distribution, but it will probably work on Fedora (and Red Hat, for sure) as well. read more...
