How to use PHP-FPM optimization to improve the performance of CodeIgniter applications

Abstract:
Performance is a very important consideration when developing web applications. CodeIgniter is a very popular PHP framework that helps developers quickly build efficient web applications. However, CodeIgniter applications may encounter performance bottlenecks when handling a large number of requests. In order to improve performance, we can use PHP-FPM to optimize the CodeIgniter application. This article will introduce how to configure and use PHP-FPM to improve the performance of CodeIgniter applications.

1. What is PHP-FPM?
   PHP-FPM (FastCGI Process Manager) is a PHP extension module that can provide high-performance PHP processing. It uses the FastCGI protocol to connect web servers with PHP applications, providing efficient process management and load balancing.
2. Install and configure PHP-FPM
   First, we need to install PHP-FPM. For specific installation steps, please refer to PHP official documentation. After the installation is complete, we need to configure PHP-FPM to adapt to our CodeIgniter application.

Open the PHP-FPM configuration file (usually located in /etc/php-fpm.conf), find the following options, and configure them:

pm = dynamic
pm.max_children = 50
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 20

In the above configuration, pm specified The process management method is dynamic mode. pm.max_children represents the maximum number of child processes that PHP-FPM can create. pm.start_servers indicates the number of child processes to be created by PHP-FPM at startup. pm.min_spare_servers and pm.max_spare_servers represent the range of the number of child processes that PHP-FPM maintains while running.

After completing the configuration, save and close the configuration file. Then, restart the PHP-FPM service.

3. Configuring the CodeIgniter application
   Next, we need to configure the CodeIgniter application to work with PHP-FPM.

Open the CodeIgniter configuration file (usually located at application/config/config.php), find the following options, and configure them:

$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';

Set $config['index_page'] Is an empty string to remove index.php from the URL. Set $config['uri_protocol'] to AUTO to enable CodeIgniter to automatically detect URI request functionality.

4. Modify nginx or Apache configuration file
   In the case of using PHP-FPM, we also need to adjust the configuration file of the web server (such as nginx or Apache) to work with PHP-FPM.

Taking nginx as an example, open the nginx configuration file (usually located at /etc/nginx/nginx.conf), find the following options, and configure them:

location ~ .php$ {
  fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
  fastcgi_index index.php;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  include fastcgi_params;
}

Change fastcgi_pass The value is set to the sock file path of PHP-FPM (can be viewed through phpinfo()).

After completing the configuration, save and close the configuration file. Then, restart the nginx service.

5. Test CodeIgniter application performance
   Now, we can use performance testing tools (such as ApacheBench) to test the performance of the CodeIgniter application.

Open the terminal and run the following command:

ab -n 1000 -c 100 http://yourdomain.com/

The above command will send 1000 requests to the specified URL, with 100 concurrent requests each time. Depending on your actual situation, you can adjust the values ​​of the -n and -c options.

Based on the test results, you can analyze the performance bottlenecks of the CodeIgniter application and make corresponding optimizations.

Conclusion:
By using PHP-FPM, we can improve the performance of CodeIgniter applications. The advantages of using PHP-FPM include efficient process management and load balancing. In addition to the configuration and optimization methods introduced above, you can further adjust and optimize the configuration of PHP-FPM and CodeIgniter according to actual needs to obtain better performance.
