Installing PHP 5.3, Nginx And PHP-fpm On Ubuntu/Debian

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.

How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10

How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10

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.

How To Upgrade Debian Etch To Lenny

Debian Etch is soon to be unsupported by the Debian team, therefore all Debian Linux Servers need to be upgraded to Debian Lenny. I work for Netzen (an IT Support company) and have upgraded many Linux servers to Debian Lenny over the past months, so I am providing this guide on how to upgrade Debian Etch to Debian Lenny to the HowtoForge community.

How To Add Two-Factor Authentication To Openvpn AS With The WiKID Strong Authentication Server

It's been a while since our last tutorial on how to add two-factor authentication to OpenVPN using the WiKID Strong Authentication System. The people at OpenVPN have been very active lately and it seems like a good time to take a look at what they've done. It's still dead simple to configure, but it is mostly done via the new slick web interface.

Trafficanalysis Using Debian Lenny

Trafficanalysis Using Debian Lenny

By using my Network Monitoring Appliance we noticed a link in MRTG always under heavy load. On this link a lot of different traffic aggregates, so we decided to analyze of what quantities of protocols and therefore applications the cumulative traffic consists.

How To Set Up Apache2 With mod_fcgid And PHP5 On OpenSUSE 11.2

Tue, 02 Feb 2010 18:23:52 +0100

How To Set Up Apache2 With mod_fcgid And PHP5 On OpenSUSE 11.2

This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on OpenSUSE 11.2. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.

How To Configure ISA Proxy/Auth Setting For Yum

I was running CentOS in my LAN for my personal use and there are MS ISA servers for proxying and each user has to use his/her user name & password for Internet. So when I used my credentials in my web browser I had no problem but when I was going to do yum no success. After some googling I found this solution.

Setting Up A PXE Install Server On Ubuntu 9.10

Mon, 01 Feb 2010 17:48:05 +0100

Setting Up A PXE Install Server On Ubuntu 9.10

This tutorial shows how to set up a PXE (short for preboot execution environment) install server with Ubuntu 9.10 (Karmic Koala). A PXE install server allows your client computers to boot and install a Linux distribution over the network, without the need of burning Linux iso images onto a CD/DVD, boot floppy images, etc. This is handy if your client computers don't have CD or floppy drives, or if you want to set up multiple computers at the same time (e.g. in a large enterprise), or simply because you want to save the money for the CDs/DVDs.

VBoxHeadless - Running Virtual Machines With VirtualBox 3.1 On A Headless Ubuntu 9.10 Server

Sun, 31 Jan 2010 17:59:02 +0100

VBoxHeadless - Running Virtual Machines With VirtualBox 3.1 On A Headless Ubuntu 9.10 Server

This guide explains how you can run virtual machines with Sun VirtualBox 3.1 on a headless Ubuntu 9.10 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

How To Back Up MySQL Databases With mylvmbackup On Debian Lenny

Fri, 29 Jan 2010 16:48:35 +0100

How To Back Up MySQL Databases With mylvmbackup On Debian Lenny

mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on a Debian Lenny server.

How To Set Up A USB-Over-IP Server And Client With OpenSUSE 11.2

Thu, 28 Jan 2010 18:00:49 +0100

How To Set Up A USB-Over-IP Server And Client With OpenSUSE 11.2

This tutorial shows how to set up a USB-over-IP server with OpenSUSE 11.2 as well as a USB-over-IP client (also running OpenSUSE 11.2). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices.

Installing mod_geoip for Apache2 On Ubuntu 9.10

Thu, 28 Jan 2010 12:24:44 +0100

Installing mod_geoip for Apache2 On Ubuntu 9.10

This guide explains how to set up mod_geoip with Apache2 on an Ubuntu 9.10 system. mod_geoip looks up the IP address of the client end user. This allows you to redirect or block users based on their country. You can also use this technology for your OpenX (formerly known as OpenAds or phpAdsNew) ad server to allow geo targeting.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 9.10 (Karmic Koala)

Wed, 27 Jan 2010 19:02:14 +0100

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 9.10 (Karmic Koala)

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

Striping Across Four Storage Nodes With GlusterFS On Ubuntu 9.10

Tue, 26 Jan 2010 18:06:37 +0100

Striping Across Four Storage Nodes With GlusterFS On Ubuntu 9.10

This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Ubuntu 9.10) with GlusterFS. The client system (Ubuntu 9.10 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.
