Comments: 1 High-Availability Storage With GlusterFS 3.2.x On Ubuntu 11.10 - Automatic File Replication (Mirror) Across Two Storage Servers This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 11.10) 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 (Ubuntu 11.10 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.

PHP-FPM/Nginx Security In Shared Hosting Environments (Debian/Ubuntu)

Comments: 7 PHP-FPM/Nginx Security In Shared Hosting Environments (Debian/Ubuntu) If you want to use nginx and PHP-FPM for shared hosting environments, you should make up your mind about security. In Apache/PHP environments, you can use suExec and/or suPHP to make PHP execute under individual user accounts instead of a system user like www-data. There's no such thing for PHP-FPM, but fortunately PHP-FPM allows us to set up a "pool" for each web site that makes PHP scripts execute as the user/group defined in that pool. This gives you all the benefits of suPHP, and in addition to that you don't have any FTP or SCP transfer problems because PHP scripts don't need to be owned by a specific user/group to be executed as the user/group defined in the pool.

Comments: 0 Using GeoIP With Nginx On Debian Squeeze/Ubuntu 11.04 This tutorial explains how to use the GeoIP module with nginx on Debian Squeeze/Ubuntu 11.04 to find out where your visitors come from. The GeoIP module sets multiple variables like $geoip_country_name, $geoip_country_code, $geoip_city, etc. that you can use in your PHP scripts or directly in your nginx configuration, for example to serve content in different languages based on the user's country.

Comments: 0 Icinga Configuration For Nginx On Debian Wheezy/Ubuntu 11.10 Icinga is an enterprise grade open source monitoring system which keeps watch over networks and any conceivable network resource, notifies the user of errors and recoveries and generates performance data for reporting. It is a fork of Nagios. This tutorial explains how to serve the Icinga Web interface from an nginx server on Debian Wheezy/Ubuntu 11.10 (the tutorial might work for Debian Squeeze as well but I didn't test; Squeeze's Icinga version is a lot older than the versions for Wheezy and Ubuntu 11.10, so there might be small differences).
