Ruby on Rails on Red Hat

Post date: November 27, 2006, 07:11 Category: Network Views: 6438 Comments
Tutorial quote: Ruby on Rails is an open source freely available web development framework. It's been quite popular--it won a Jolt "Web Development Tools" award last year, and some prominent Java developers have publically switched to Ruby on Rails. The buzz surrounding Rails is quite impressive--particularly when you consider that Rails had no Fortune 500 company to market it, unlike .NET or Java.

Rails is a Model View Controller (MVC) framework. As you can imagine from the name, applications written using Model View Controller frameworks have three main components: a model, which represents the data and associated logic; the view, which represents how a user interacts with the application; and the controller, which contains all of the business logic that drives the application. This is an artificial distinction, of course, but it is a powerful one.

You'll need Apache 2.0+ and MySQL installed on your Red Hat Linux computer to run these examples.

Ruby on Rails on Debian

Post date: January 10, 2006, 17:01 Category: Network Views: 2735 Comments
Tutorial quote: Most of you have probably heard of Ruby on Rails and may be wondering what exactly it does and how you can try it for yourself. Put simply, Rails is a web application framework that uses the model-view-controller software design pattern to allow for rapid development of web applications. This article will cover how to install Rails on Debian and how to configure it to work with Apache and a relational database of your choice.

Using Ruby On Rails With Apache2 On Debian Etch

Post date: May 27, 2007, 23:05 Category: System Views: 3689 Comments
Tutorial quote: This article shows how you can install Ruby on Rails (RoR) and integrate it in Apache2 on a Debian Etch system. Ruby on Rails is a web application framework which is rapidly gaining popularity among web programmers. It aims to increase the speed and ease with which database-driven web sites can be created and offers skeleton code frameworks (scaffolding) from the outset. Applications using the RoR framework are developed using the Model-View-Controller design pattern.

NIST Publically-Released Red Hat Enterprise Linux Benchmark

Post date: October 21, 2006, 04:10 Category: Benchmarks Views: 6610 Comments
Tutorial quote: The Benchmark is a compilation of security configuration actions and settings that "harden" Red Hat Linux operating systems. It is a CIS Level-I benchmark: the prudent level of minimum due care for operating system security. This benchmark was developed and tested on Red Hat Enterprise Linux (RHEL) including RHEL 2.1, RHEL 3.0, and Fedora Core 1, 2, & 3. It is likely to work for other Linux distributions - especially Red Hat and Fedora derivatives - as well.

Choosing an I/O Scheduler for Red Hat Enterprise Linux 4

Post date: July 18, 2005, 22:07 Category: Benchmarks Views: 7444 Comments
Tutorial quote: The Linux kernel, the core of the operating system, is responsible for controlling disk access by using kernel I/O scheduling. Red Hat Enterprise Linux 3 with a 2.4 kernel base uses a single, robust, general purpose I/O elevator. The 2.4 I/O scheduler has a reasonable number of tuning options by controlling the amount of time a request remains in an I/O queue before being serviced using the elvtune command. While Red Hat Enterprise Linux 3 offers most workloads excellent performance, it does not always provide the best I/O characteristics for the wide range of applications in use by Linux users these days. The I/O schedulers provided in Red Hat Enterprise Linux 4, embedded in the 2.6 kernel, have advanced the I/O capabilities of Linux significantly. With Red Hat Enterprise Linux 4, applications can now optimize the kernel I/O at boot time, by selecting one of four different I/O schedulers.

Taking advantage of SELinux in Red Hat Enterprise Linux

Post date: April 15, 2005, 21:04 Category: Security Views: 3774 Comments
Tutorial quote: The release of Red Hat Enterprise Linux 4 debuts the first commercially supported inclusion of Security-Enhanced Linux (SELinux). An installation of Red Hat's latest enterprise operating system has SELinux installed and enabled by default. In the past SELinux has been criticized for a lack of commercial support, many big sites were unable to use it due to the lack of support (Fedora Core 3 doesn't have the support that they require). Now in Red Hat Enterprise Linux 4, SELinux is a supported part of the OS, and such objections to the use of SELinux have gone away. SELinux is now widely regarded as being suitable for the largest sites.

The perfect Setup - White Box Linux

Post date: April 15, 2005, 23:04 Category: Installing Views: 6042 Comments
Tutorial quote: This is a detailed description about the steps to be taken to setup a Linux server based on White Box Linux that offers all services needed by ISPs and hosters (web server (SSL-capable), mail server (with SMTP-AUTH and TLS!), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.).

Since White Box Linux is very similar to Red Hat Enterprise Linux this tutorial should also work for Red Hat Enterprise Linux.
