Centos 6 Running 2 Version Php On Nginx

Introduction

Centos 6 can be used for web applications and websites based on php and nginx. This tutorial provides instructions on how to install and configure two different versions of php and nginx on a Centos 6 server. This article assumes you are familiar with basic Linux commands and that you have experience working with Centos 6.

What is Nginx?

Nginx is an open-source web server that is designed to handle high traffic loads, act as a reverse proxy, and be lightweight and fast. It has become the most popular web server for busy websites that need high performance and usability. It is free and has lots of available extensions and third-party modules.

What is Php?

Php is a widely used server-side scripting language primarily used to create dynamic website. It’s relatively easy to learn and is used by developers to create sites that include interactive elements like login forms, search functions, database interactions, and more. Php can be used on many different web server types, including Apache, IIS, and Nginx.

How to Install and Configure Nginx and Php

Installing and configuring nginx and php on a Centos 6 server is relatively easy. The first step is to install the nginx web server. You will need to download the sources and extract the files. Then you can use the yum repository to install nginx.

Once nginx is installed, you can configure it according to your requirements. You can edit the nginx configuration file to control how nginx handles incoming requests and configure modules. You can also configure logging and access control.

After nginx is configured, you can install php. Centos 6 comes with three versions of php (5.3, 5.4, and 5.5). You can either use the yum command to install a specific version or install them all. After php is installed, you can configure it according to your requirements. You can edit the php.ini file to set server-wide configurations such as error logging and file upload limits.

Running Multiple Versions of Php on Nginx

It is possible to run multiple versions of php on nginx with the use of FastCGI. FastCGI is a protocol that allows a web server to communicate with a script processor, such as php. The FastCGI process manager can be used to spawn multiple php interpreters and assign them to different domains or virtual hosts. This allows you to run different php versions on different domains or virtual hosts.

To configure FastCGI on Centos 6 for nginx, you will need to install the nginx FastCGI module and the spawn-fcgi package. Then you can configure the nginx configuration file to use the FastCGI module and spawn the php interpreters. After the php interpreters are spawned, you can assign them to different domains or virtual hosts.

Conclusion

By following the instructions in this article, you should now be able to install and configure nginx and php on a Centos 6 server. You should also be able to run multiple versions of php on a single nginx web server with the help of FastCGI. Nginx and php can be used to create powerful and dynamic websites and web applications.
