New Wordpress site for 2010
Posted on 06.Jan 2010 by Ray Heffer in Web HostingJust in time for the start of the new year I decided to ditch the old RayHeffer.com site and replace it with a brand spanking new Wordpress site running on my virtual Linux server in London. I have spent the past few nights up late tweaking the new site and adding content, so please look around and don’t forget to leave me a comment!
It’s snowing outside as I write this here in the south east UK, so what better time to develop your Linux skills and build your own virtual Linux server by following my new LAMP guide based on CentOS 5?
Happy New Year!

Building a secure web server with CentOS 5, part 1
Posted on 05.Jan 2010 by Ray Heffer in LAMP, Linux, Web HostingPart 1 | Part 2 | Part 3 | Troubleshooting
Introduction
This is an updated version of my original LAMP (Linux Apache MySQL and Perl/PHP) guide that was based on CentOS 4. Now updated and tweaked for CentOS 5, I will take you through the steps required to build a secure Linux web server (LAMP) on CentOS 5.
I have a background working for an ISP, so I’ve based this build on the same configuration many hosting providers use. It supports virtual hosts (multiple websites), secure FTP access, locked down SSH access, and a sensible directory structure.
If you follow this guide, you will get a web server up and running within a couple of hours depending on whether you follow it step by step, or prefer to experiment first. If you are new to Linux then give it a try and learn something new, you never know you may surprise yourself!
Good luck!

Part 2: Configuring the Server
Configuring CentOS
- Edit
/etc/hostsand/etc/sysconfig/networkwith hostnames - Install Packages
Example of /etc/hosts:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
67.34.32.11 www.mydomain.com
Example of /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=www.mydomain.com
Installing Packages
# yum -y install httpd openssl-devel openssl mod_ssl vsftpd rpm-build rpm-devel autoconf automake lynx gcc
# yum -y install mysql mod_auth_mysql mysql-devel mysql-server
# yum -y install mod_python python python-devel

Part 3: Adding websites
In the following steps, we will base our configuration on a fictitious company called Happy Burger who has already registered the domain name, happyburger.net. We will point www.happyburger.net to the IP address of this web server. When you are creating your own site, substitute the customer name and domain name for that of the actual customer. * If a Happy Burger really exists, then this is in no way associated with them and is purely coincidental.
Create a User Account
The first step is to create a user account that will be associated with this website and be used to authenticate via FTP. When creating the password, make sure that it is at least 8 characters, alphanumeric, mixed case and includes numbers. I usually generate random passwords for this.
# adduser –s /sbin/nologin happyburger
# passwd happyburger
Creating the directory structure
Each website must have the following directory structure in order to support access logs, web statistics, .htpasswd files, CGI scripts and the public web directory.
