CMON is a daemon that aggregates information from MySQL Cluster that earlier was only accessible from the cluster log or the management client, such as: * cluster state * node state * backup statistics * statistics * cluster events (cluster log basically) .. and let's you access the information using SQL, because CMON logs the information into ordinary MYISAM tables! So, it is really easy to use! In the package you also get get php scripts that you can put on your webserver to generate graphs and get a www interface to CMON. CMON can also start ndbd nodes and make decisions on how they should be started (with or without --initial). CMON starts as a daemon and will automatically create cmon database and install the necessary tables automatically.

Comment mettre à jour plusieurs Wordpress en une seule fois | Korben

(via)
Si vous avez un serveur sur lequel vous gérez une floppé de Wordpress, voici un petit script crée par les amis Billyboylindien et Xorax qui va vous permettre de mettre à jour tous ces wordpress en un seul coup… Alors bien sûr les plus sournois d’entre vous vont me dire : “Ouiii mais euuuh, y’a wordpress MU j’te ferai dire d’abord que j’te signale !” Effectivement, Wordpress MU est une version particulière de Wordpress qui permet via une seule install de Wordpress d’avoir x blogs… Très bien mais toujours mis à jour en décalé par rapport à Wordpress standard et tout le monde n’a pas forcement installé un Wordpress MU dès le départ (genre : moi !) Du coup, ce script de mise à jour est vraiment le bienvenu. Une fois que vous l’avez paramètré et rendu exéutable, il se chargera automatiquement de téléchager la dernière version de Wordpress, fera un backup de vos fichiers et de votre base de donnée, et mettra en place les nouveaux fichiers de Wordpress sans bousiller toute votre install (donc sans toucher à wp-content). Tip top quoi !

Install SugarCRM community edition in Ubuntu 8.10 Server -- Ubuntu Geek

(via)
SugarCRM is a complete CRM system for businesses of all sizes. Core CRM functionality includes sales force automation, marketing campaigns, support cases, project management, calendaring, and more. It supports MySQL and MS SQL Server. Sugar consists of modules, each of which represents a specific functional aspect of CRM such as Accounts,Activities, Leads, and Opportunities. For example, the Accounts module enables you to create and manage customer accounts, and the Activities module enables you to create and manage activities related to accounts, opportunities, etc. These modules are designed to help you manage customer accounts through each step of their lifecycle, starting with generating and qualifying leads to customer support and resolving reported bugs. Because many of these steps are interrelated, each module displays related information. For example, when you view the details of a particular account, the system also displays the related contacts, activities,opportunities, and bugs. You can not only view and edit this information but also create new information. As an administrator, you have the power to implement access control for these modules. You can customize the look and feel of Sugar across your organization. You can even create new modules if needed. You can also create multiple forums as platforms of discussion on various topics amongst your users and customers.

Install and setup Xen on Debian 4.0 Etch — Lone-Wolf Scripts

(via)
Xen is a GPLed virtualization solution available in Debian 4.0 Etch repositories. This article help you to create a coherent Xen installation, with backups and minimum security enhancements. This guide fits my vision of a Xen setup. If it does not fit yours, you are free to adapt it to your needs, or to not use it. For information In this guide, i use the term "virtual host". Be aware that Xen use its own terminology. In a Xen setup, instanciated (aka. started) virtual hosts are called "Domains". Once your computer configured for Xen, all the operating systems run in "domains". The original operating system, where the Xen's control tools are installed, is called "dom0" (for domain No zero). All the guest operating systems are said to be installed in a "domU" (for User domain). As i'm a little lazy (well, yeah... very lazy), i don't want to endure this mind twisting, and i will mainly use the "virtual host" term in this guide. So, if you read this guide, don't by angry at me because of the terms i use.

Execute commands simultaneously on multiple servers Using PSSH/Cluster SSH/Multixterm -- Ubuntu Geek

If you have multiple servers with similar or identical configurations (such as nodes in a cluster), it’s often difficult to make sure the contents and configuration of those servers are identical. It’s even more difficult when you need to make configuration modifications from the command line, knowing you’ll have to execute the exact same command on a large number of systems . In this tutorial we will see some tools to execute one command on multiple remote servers using ssh.First you need to make sure you have ssh installed in your machine or you can install using the following command

Additions to a default Ubuntu 8.10 Intrepid Ibex install — Lone-Wolf Scripts

Last Ubuntu versions enable you to install software by clicking on a link in your browser.

Preventing MySQL Injection Attacks With GreenSQL On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by 1 other
GreenSQL (or greensql-fw) is a firewall for MySQL databases that filters SQL injection attacks. It works as a reverse proxy, i.e., it takes the SQL queries, checks them, passes them on to the MySQL database and delivers back the result from the MySQL database. It comes with a web interface (called greensql-console) so that you can manage GreenSQL through a web browser. This guide shows how you can install GreenSQL and its web interface on a Debian Etch server.

Zimbra on a VPS: Tuning - Misc - Rob Thompson

Out of the box, Zimbra is tuned for a fairly beefy machine. Zimbra will easily consume 1.5GB of ram with default settings. Some of these changes mean turning off a few Zimbra features and there are quite a few ways to do this, so you will need to evaluate memory usage given your own situation. If you simply can't live without *all* the Zimbra features or intend to support a larger (> 15) number of users, my only suggestion is to get more ram ;). But if you are willing to make some compromises, please read on. The changes below are ones that I found to be a reasonable compromise. With a few easy changes, you can bring the memory consumption way down, so that it will hum along just fine on a server with ~512MB of ram. Of course this reduces the amount of users that your server can support, but I've found that for a small installation of around 15 users, these settings will work just fine and give you the same performance as the out-of-the-box config with gobs of RAM. The server I have been testing with has 560MB of ram, and after tuning consumes all the ram and only about 80MB of swap on average. You will find that if you don't make changes similar to the ones suggested below with ~512MB of ram, your Zimbra install will slowly creep up its consumption of swap and your Zimbra install will start to crawl. Also, > 512MB seems to be about the minimum amount of ram to get a useful/zippy server

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by 1 other (via)
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.

Installing ModSecurity2 On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by 2 others
This article shows how to install and configure ModSecurity (version 2) for use with Apache2 on a Debian Etch system. ModSecurity is an Apache module that provides intrusion detection and prevention for web applications. It aims at shielding web applications from known and unknown attacks, such as SQL injection attacks, cross-site scripting, path traversal attacks, etc. I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!
