Linux nginx Multi-version PHP coexistence

Application environment

LNMP environment, the current PHP version 5.3.8, encountered an application need only support PHP 5.2.x, but also want to keep existing applications or PHP 5.3.8. This means that two versions of PHP are required to be present at the same time for Nginx to invoke different versions as needed.

Ideas

Nginx interacts with PHP via php-fastcgi. And php-fastcgi run will be through the file, or the local port two ways to listen, in Nginx configuration of the corresponding fastcgi listening port or file is to implement Nginx request for PHP interpretation.

Since php-fastcgi is listening port and file, it can let different versions of php-fastcgi run simultaneously, listen to different ports or files, Nginx in accordance with the requirements of the configuration call different php-fastcgi port or file, you can achieve different versions of PHP coexistence.

Configuration Records

The following document is a simple configuration process based on the Debian environment where LNMP is already installed. The current version of PHP is 5.3.8, located in/usr/local/php.

Make zend_extra_libs= '-liconv '

Make install

<value name= "Listen_address" >127.0.0.1:9001</value>

Or listen to the file:

<value name= "Listen_address" >/path/to/unix/socket</value>

Additional parameters are customized to the server environment and requirements.

/USR/LOCAL/PHP-5.2.14/SBIN/PHP-FPM start

After the word php5.3.3, PHP has inherited php-fpm into PHP, and the built-in PHP-FPM default does not support (start|stop|reload) The smooth start parameters, you need to use the official source code provided in the boot script to control:
