Running SugarCRM Community Edition On Nginx (LEMP) (Debian Squeeze/Ubuntu 11.04)

Post date: November 3, 2011, 08:11 Category: Installing Views: 22068 Comments
Tutorial quote: SugarCRM is a webbased CRM solution written in PHP. SugarCRM is available in different flavours called "Editions" ("Community" (free), "Professional", and "Enterprise"). In this tutorial I will describe the installation of the free Community Edition on a Debian Squeeze or Ubuntu 11.04 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). With the modules My Portal, Calendar, Activities, Contacts, Accounts, Leads, Opportunities, Cases, Bugtracker, Documents and Email, SugarCRM Community Edition offers everything that can be expected from a CRM solution.

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch

Post date: August 24, 2008, 11:08 Category: Installing Views: 4302 Comments
Tutorial quote: This article explains how you can install and configure apache2-mpm-peruser on a Debian Etch server. apache2-mpm-peruser is an MPM (Multi-Processing Module) for the Apache 2 web server, very similar to apache2-mpm-itk, but faster (almost as fast as apache2-mpm-prefork). mpm-peruser allows you to run each of your vhosts under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. It is based on metuxmpm, a working implementation of the perchild MPM. The result is a sane and secure web server environment for your users, without kludges like PHP's safe_mode.

Setting up a local web server in Debian Linux

Post date: January 21, 2006, 06:01 Category: Network Views: 3545 Comments
Tutorial quote: Any web developer, designer, or webmaster can benefit from having a local web server. Even if that developer has no interest in securing and maintaining the server his or her websites live on, a local server can act as a convenient mirror for testing updates, trying new designs, and other general sand-boxing activities.

Web developers whose hosts utilize the popular LAMP platform (Linux + Apache + MySQL + PHP) are frequently hit with a dilemma. Since understanding Linux is not a prerequisite for website administrators, many of them lack the knowledge necessary for setting up a LAMP server from scratch (or at least they may think so). But thanks to the improved package management on Linux distributions like Debian, installing a functional web server is not nearly the chore it was just a couple years ago.

Server Monitoring With munin And monit On Debian Etch

Post date: May 13, 2007, 21:05 Category: System Views: 4740 Comments
Tutorial quote: In this article I will describe how you can monitor your Debian Etch server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that let you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

The Perfect Server - Debian Lenny (Debian 5.0) With BIND & Dovecot [ISPConfig 3]

Post date: October 21, 2010, 11:10 Category: Installing Views: 4305 Comments
Tutorial quote: This tutorial shows how to prepare a Debian Lenny (Debian 5.0) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This tutorials differs from "The Perfect Server - Debian Lenny (Debian 5.0) With MyDNS & Courier [ISPConfig 3]" in that I use BIND and Dovecot here instead of MyDNS and Courier (of course, the other two variants - BIND & Courier or MyDNS & Dovecot are possible as well).

Today's Linux screen capture technology

Post date: April 12, 2005, 18:04 Category: Miscellaneous Views: 3305 Comments
Tutorial quote: "I'd like you to help me find out about video screen captures," said one of my editors a while back. "Sure, let me see what's available," I replied. He pointed me to a couple of Web sites to get me started, and here I am a few weeks later ready to share my findings. I'll discuss ways that you can make video clips in Linux, talk about their applications and shortcomings. I'll also cover suitable ways to view your masterpieces once they're recorded.

Video screen captures are useful for jobs like application training, computer instruction, or product demos. An example would be the little one-minute video I set up for my wife. She kept forgetting how to start up Mozilla Mail on her Windows 98 machine. I captured the mouse clicks and screen changes (in real time) as I ran through the process, saving it to a Macromedia Flash file. I then created a little Web page on one of my Apache servers, that described how to start Mozilla Mail and included a link to the Flash file. Instead of asking me how to do it, she can now just click on the video tutorial.

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

Post date: September 25, 2011, 16:09 Category: Security Views: 6548 Comments
Tutorial quote: 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.

Ruby on Rails on Red Hat

Post date: November 27, 2006, 07:11 Category: Network Views: 8481 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.

Setting up an Ubuntu media server

Post date: April 23, 2008, 12:04 Category: Installing Views: 15512 Comments
Tutorial quote: In today's tip I'm going to run through how to setup an Ubuntu media server. First of all, what is Ubuntu. Wikipedia says:

Ubuntu is a Linux distribution for desktops, laptops, and servers. It has consistently been rated among the most popular of the many GNU/Linux distributions. Ubuntu's goals include providing an up-to-date yet stable operating system for the average user and having a strong focus on usability and ease of installation.

It is very much like apache, which I showed you how to setup in my article on how to make your computer into a local server, in that it is commonly used as a server software. Now then, what is a media server?

To refer to Wikipedia again, a media server is

A media server is a computer appliance, ranging from an enterprise class machine providing video on demand, to, more commonly, a small home computer storing various digital media.

Basically, it's just like a local server which stores and shares solely media instead of other types of files. I'll leave the uses of one to your imagination. Let's on with setting it up.
