Web server with CentOS + Apache

In this brief article we will cover the installation and configuration of Apache on CentOS and some other functions required in today’s web servers. Although there are already plenty of material about it, a simple Google search returns a number of texts already, I decided to write about it because it is something simple that sometimes escapes from memory, having published the text is easier to see later and also did not find here any similar text in Vol.

To begin, let’s put some basic descriptions, because there’s always a first-timer. CentOS is a distribution Linux Enterprise class derived from source code freely distributed by Red Hat Enterprise Linux and maintained by the CentOS Project. The version numbering is based on the number of Red Hat Enterprise Linux. For example, CentOS is based on Red Hat Enterprise Linux. The basic difference between them is the provision of support paid on acquisition of a Red Hat Enterprise Linux.

Functionally, it can be considered as clone systems. CentOS provides greater access to industry-standard software, including full compatibility with the software packages prepared specifically for systems Red Hat Enterprise Linux. This gives you the same level of safety and support via updates that other Enterprise Linux solutions, but without cost. Supports both server environments for mission critical environments and workstations and also has a Live CD version.

CentOS has numerous advantages, including: an active and growing community, a rapid development and testing of packages, an extensive network for downloads, accessible developers, multiple channel support including support in India. and commercial support through partners. Centos Apache server (Apache HTTP Server, or simply, Apache) is the most successful free web server.

It was created in 1995 by Rob McCool, then an official of the NCSA (National Center for Supercomputing Applications). In a survey conducted in December 2007, it was found that using the Apache represents 47.20% of active servers in the world. It is the core technology of the Apache Software Foundation, responsible for more than a dozen projects involving technology webcast, data processing and execution of distributed applications.

The dedicated server is compatible with the HTTP protocol. Its features are maintained through a structure of modules, including allowing the user to write their own modules – using the API software. It is available in versions for Windows OS and the various other POSIX (Unix , Linux, FreeBSD, etc.).

PHP (recursive acronym for “PHP: Hypertext Preprocessor”) is a computer programming language interpreted freely and widely used for generating dynamic content on the World Wide Web such as Wikipedia.

MySQL is a database management system (DBMS) using SQL (Structured Query Language) as an interface. It is currently one of the most popular databases, with more than 10 million installations worldwide.
