Nginx and PHP

Nginx and PHP combined, nginx parsing Dynamic Web pages, and PHP Dynamic Web page to the PHP processing, the solution:

---from the nginx angle

• Using Nginx's proxy module
• Using the FastCGI module

---from the perspective of PHP

• Run in PHP-FPM mode
• PHP comes with the fastcgi server
• The spawn-fcgi of the lighttpd belt

1) PHP Installation

• Typical compilation installation
• Yum installation: Yum install PHP

To restart PHP:

• Killall PHP-FPM
• /opt/php-5.3.22/sbin/php-fpm

2) Management PHP-FPM

Control signals that can be used by the master master process of PHP-FPM:

• SIGINT, Sigterm: terminate the process immediately
• Sigquit: Smooth Termination process
• SIGUSR1: Reopen log file
• SIGUSR2: Smooth reload of all worker processes and reload configuration and binary modules

3) In addition to the main profile nginx.conf in Nginx, there are two fastcgi related profiles: fastcgi.conf and Fastcgi_params

4) Monitor the status of PHP-FPM by configuring php-fpm.conf and nginx.conf configuration files
