How To Set Up MySQL Database Replication With SSL Encryption On Debian Lenny

Sun, 29 Aug 2010 18:41:35 +0200

How To Set Up MySQL Database Replication With SSL Encryption On Debian Lenny

This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures though.

Installing A Multiserver Setup With Dedicated Web, Email, DNS And MySQL Database Servers On Debian 5.0 With ISPConfig 3

Tue, 17 Aug 2010 18:11:18 +0200

Installing A Multiserver Setup With Dedicated Web, Email, DNS And MySQL Database Servers On Debian 5.0 With ISPConfig 3

This tutorial describes the installation of an ISPConfig 3 multiserver setup with dedicated web, email, database and two DNS servers all managed trough a single ISPConfig 3 control panel. The setup described below uses five servers and can be extended easily to to a higher number of servers by just adding more servers. E.g. if you want to have two mailservers, do the setup steps from chapter 2 on both of these servers. If you want to set up more web servers, then install ISPConfig on all other web servers in expert mode except of the first one.

Installing A Web, Email And MySQL Database Cluster (Mirror) On Debian 5.0 With ISPConfig 3

Tue, 10 Aug 2010 17:21:09 +0200

Installing A Web, Email And MySQL Database Cluster (Mirror) On Debian 5.0 With ISPConfig 3

This tutorial describes the installation of a clustered Web, Email, Database and DNS server to be used for redundancy, high availability and load balancing on Debian 5 with the ISPConfig 3 control panel. GlusterFS will be used to mirror the data between the servers and ISPConfig for mirroring the configuration files. I will use a setup of two servers here for demonstration purposes but the setup can scale to a higher number of servers with only minor modifications in the GlusterFS configuration files.

Caching With Apache's mod_cache On Debian Lenny

This article explains how you can cache your web site contents with Apache's mod_cache on Debian Lenny. If you have a high-traffic dynamic web site that generates lots of database queries on each request, you can decrease the server load dramatically by caching your content for a few minutes or more (that depends on how often you update your content).

Install Imule On Debian Lenny

Install Imule On Debian Lenny

When I write these lines, the latest version of Imule is 1.4.6. But ... It relies on packages version (libgcj10, libstdc++6) that are released with the unstable (sid) version of Debian. So either you upgrade Debian to unstable version or you choose a lower version of Imule. I chose the latter: to install an old version of Imule. I tested few of them and 1.3.5 seems to work quite well with Debian Lenny (stable).

Installing PowerDNS (With MySQL Backend) And Poweradmin On Debian Lenny

Thu, 08 Jul 2010 17:33:25 +0200

Installing PowerDNS (With MySQL Backend) And Poweradmin On Debian Lenny

This article shows how you can install the PowerDNS nameserver (with MySQL backend) and the Poweradmin control panel for PowerDNS on a Debian Lenny system. PowerDNS is a high-performance, authoritative-only nameserver - in the setup described here it will read the DNS records from a MySQL database (similar to MyDNS), although other backends such as PostgreSQL are supported as well. Poweradmin is a web-based control panel for PowerDNS.

Installing Maia Mailguard On Debian Lenny (Virtual Users/Domains With Postfix/MySQL)

Installing Maia Mailguard On Debian Lenny (Virtual Users/Domains With Postfix/MySQL)

This guide explains how to install Maia Mailguard, a spam and virus management system, on a Debian Lenny mailserver. Maia Mailguard is a web-based interface and management system based on the popular amavisd-new email scanner and SpamAssassin. Written in Perl and PHP, Maia Mailguard gives end-users control over how their mail is processed by virus scanners and spam filters, while giving mail administrators the power to configure site-wide defaults and limits.

Apache And MySQL Monitoring With Bijk On Debian Lenny

Fri, 25 Jun 2010 16:24:22 +0200

Apache And MySQL Monitoring With Bijk On Debian Lenny

This tutorial describes how you can monitor your server with the tool Bijk. Bijk creates online 30 graphs about load, CPU, memory, traffic, Apache, NginX, PostreSQL and others with alerts. Bijk can be used on Debian, Ubuntu, CentOS, RedHat and Gentoo. In this article I will explain how to install Bijk on Debian.

Generating Web Site Statistics With AWStats & JAWStats On Debian Lenny

Thu, 24 Jun 2010 16:48:43 +0200

Generating Web Site Statistics With AWStats & JAWStats On Debian Lenny

This tutorial explains how you can generate statistics for your web site with AWStats and JAWStats on a Debian Lenny web server. AWStats is a free powerful and featureful tool that generates advanced web server statistics. JAWStats runs in conjunction with AWStats and produces clear and informative charts, graphs and tables about your website visitors. AWStats is able to create graphical web pages for the statistics, but JAWStats presents this data in a much nicer way - it's much better organized and makes use of Ajax and Flash.

Disk Backup With Amanda On Debian Lenny

Amanda is an open source client/server solution to back up filesystems. Backups are triggered by the backup server, backup definitions are located on the servers but exclusion lists are located on the client.

Installing Nginx With PHP 5.3 And PHP-FPM On Ubuntu Lucid Lynx (10.04) Without Compiling Anything

Mon, 14 Jun 2010 19:52:47 +0200

Installing Nginx With PHP 5.3 And PHP-FPM On Ubuntu Lucid Lynx (10.04) Without Compiling Anything

Since Apache is most of the time a memory hungy process, people started to look for different ways to host their website. Apache is clearly not the only webserver available. A few good examples are lighttpd and nginx. In this tutorial I will show you how to install it on your Ubuntu server. This tutorial also applies to Debian, though. There is only a very small difference.

Postfix Monitoring With Mailgraph And pflogsumm On Debian Lenny

Sun, 13 Jun 2010 17:25:20 +0200

Postfix Monitoring With Mailgraph And pflogsumm On Debian Lenny

This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix (e.g. using amavisd-new). These graphs can be accessed with a browser, whereas pflogsumm ("Postfix Log Entry Summarizer") can be used to send reports of Postfix activity per email.

Using DPKG To Install OpenVZ On Debian

To use the DPKG package manager to install OpenVZ, all you need to do is download the OpenVZ components, and let DPKG do the rest.

Protect phpMyAdmin On An ISPConfig 3 Server (Debian)

Fri, 21 May 2010 15:30:14 +0200

Protect phpMyAdmin On An ISPConfig 3 Server (Debian)

With this small howto I explain how to protect your phpmyadmin installation on your Debian server with ISPConfig3 against hack attempts as much as possible. I assume that you already have an ISPConfig3 server running on Debian, which has been set up according to this howto and that phpmyadmin has been installed from the Debian repository into the directory /usr/share/phpmyadmin. With this default setup you can access phpMyAdmin via: http://www.anywebsiteonyourserver.tld/phpmyadmin, which we're going to change for security reasons.

Sphinx As MySQL Storage Engine (SphinxSE)

Wed, 19 May 2010 17:22:58 +0200

Sphinx As MySQL Storage Engine (SphinxSE)

SphinX is a great full-text search engine for MySQL. Installing the Sphinx daemon was straightforward as you can compile it from the source or use a .DEB/.RPM package but SphinxSE was a little bit tricky since it needed to be installed as a plugin on a running MySQL server. So if you use Debian or Centos and install your MySQL from a .deb or .rpm package this is how you do it.
