CentOS - Installing Nginx via yum

Nginx is a popular lightweight server for those who do not need the bulk and extra services that Apache may offer.
This article will look at installing Nginx on a CentOS Slice using the 'yum' package manager.

CentOS - Mail Server- Installation

The base package for all of the mail articles will be Postfix. There are, of course, alternatives to Postfix, each with advantages and disadvantages and, without going into the differences, I have chosen Postfix due its relative ease of configuration.
As many of the future articles will concentrate on administrative issues and assume Postfix is already installed, let's go ahead and install it.

How to setup VPS or dedicated server with a kloxo admin panel

CentOS – Apache configuration #2

Continuing from the first CentOS Apache configuration article, we now look at some of the other settings in the main httpd.conf file and what they can do.

Concentrating on efficiency and security, this will end our httpd.conf journey (for now).

ServerName

Default: Not Set

The ServerName is usually a hostname or a FQDN (Fully Qualified Domain Name).
If you set followed the CentOS installing Apache and PHP5 article, you will have already set the ServerName configuration.

CentOS – Apache configuration #1

Let’s take a look at the main httpd.conf for our CentOS Apache install.
We’re not actually going to change a lot at this point, just look at the main settings and see what they mean and what a change will actually do

Defaults

Why no specific changes to the default? Well, it’s difficult to give a definitive configuration as there are so many variables to consider such as expected site traffic, Slice size, site type, etc.
However, we’ll discuss the main settings and you can make any decisions as to what settings you feel are best for your site.

CentOS – Installing Apache and PHP5

CentOS comes with Apache v.2.2.3 and PHP v.5.1.6 and they are easily installed via the default CentOS Package Manager ‘yum’.
The advantage of using yum (as opposed to installing via source code) is that you will get any security updates (if and when distributed) and dependencies are automatically taken care of.

CentOS – Installing MySQL

Installing MySQL on CentOS is very simple using the ‘yum’ package manager.

This article will go through the install process and also look at what other packages are needed for MySQL to integrate with Ruby on Rails and with a standard PHP install.

MySQL Install

To begin with, a simple MySQL install:

yum install mysql-server mysql mysql-devel

Note that we have installed the development libs and headers with the ‘mysql-devel’ package. This package is required by the mysql Rubygems package which we install later in this article.

CentOS 5.4 Setup – part 2

Now that we’ve secured access to our CentOS 5.4 slice we can update it and get it ready for the rest of the server install.
In part 1 of the CentOS 5.4 setup, we completed the ssh configuration along with a basic iptables setup.
Now let’s run some checks and install some personal configuration files to make life easier. Once done, we can update the install and create a solid base for the ‘meat’ of the server.

OS check
First thing is to confirm what OS we’re using. We know we should be using CentOS but let’s see:

CentOS 5.4 setup – part 1

Your CentOS 5.4 Slice will be a bare-bones install when it’s created. We need to connect via SSH and secure it as soon as possible.

Your new slice

These two articles will take you from a ‘barebones’ CentOS 5.4 Slice to a secured and up-to-date Slice ready for your server software (or whatever you use the Slice for). Not only that, you will have a better understanding of what is going on and, more importantly, why it’s going on.

This first part will walk you through setting up a new user and securing login access to your slice.
