CentOS 5.3 Samba Standalone Server With tdbsam Backend

CentOS 5.3 Samba Standalone Server With tdbsam Backend

This tutorial explains the installation of a Samba fileserver on CentOS 5.3 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access.

How To Set Up Mass Virtualhosting With Apache2 + mod_rewrite + mod_userdir + mod_suexec On CentOS 5.3

How To Set Up Mass Virtualhosting With Apache2 + mod_rewrite + mod_userdir + mod_suexec On CentOS 5.3

This howto shows one method of doing mass virtualhosting using mod_rewrite to dynamically map a list of directories on your filesystem to virtual hosts. Additionally, by rewriting the incoming URL to the user's home directory we can make use of suEXEC to have Apache execute CGI scripts as the owner of the script.

How To Install Qmailtoaster (CentOS 5.3)

How To Install Qmailtoaster (CentOS 5.3)

Qmailtoaster is a project that aims to make the installation of Qmail onto RPM based systems a snap. All of the packages are distributed in source RPMs so building the packages for your particular distro and architecture is as easy as running a script or a simple command for each package. The RPMs have all of the needed and commonly asked for patches included so you can have a mail server up and running in about an hour. When it's all complete, you'll have a full Qmail mail server installation ready for just about anything. I personally run Qmailtoaster servers for other companies and ISPs who have tens of thousands of users on their systems.

The Perfect Server - CentOS 5.3 x86_64 [ISPConfig 3]

This tutorial shows how to prepare a CentOS 5.3 x86_64 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, MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.

How To Harden PHP5 With Suhosin On CentOS 5.3

How To Harden PHP5 With Suhosin On CentOS 5.3

This tutorial shows how to harden PHP5 with Suhosin on a CentOS 5.3 server. From the Suhosin project page: "Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections."

The Perfect Server - CentOS 5.3 i386 [ISPConfig 2]

The Perfect Server - CentOS 5.3 i386 [ISPConfig 2]

This tutorial shows how to set up a CentOS 5.3 server (i386) that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of CentOS 5.3, but should apply to the 64-bit version with very little modifications as well. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).

Paravirtualization With Xen On CentOS 5.3 (x86_64)

Paravirtualization With Xen On CentOS 5.3 (x86_64)

This tutorial provides step-by-step instructions on how to install Xen (version 3.0.3) on a CentOS 5.3 (x86_64) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (CentOS 5.3 x86_64)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (CentOS 5.3 x86_64)

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database used by Postfix.
