How to improve the performance of your Drupal website through PHP-FPM optimization

How to improve the performance of your Drupal website with PHP-FPM optimization

Summary: Drupal is a powerful content management system, but it can suffer when handling a large number of requests Performance bottleneck. This article will introduce how to use PHP-FPM to optimize the performance of Drupal websites, including adjusting the configuration parameters of PHP-FPM, using the process manager, and using cache, etc., and also give specific code examples.

1. Adjust the configuration parameters of PHP-FPM

• Increase the maximum number of processes and the maximum number of requests of PHP-FPM to handle more concurrency ask. In the php-fpm.conf file, modify the following parameters:

  pm.max_children = 50      # 最大进程数
  pm.max_requests = 500     # 每个进程的最大请求数

  Copy after login

• Adjust the memory limit of PHP-FPM to improve the ability to handle large requests. In the php.ini file, modify the following parameters:

  memory_limit = 256M       # PHP进程可使用的最大内存

  Copy after login

2. Use process manager

• Use Nginx’s Worker Process or Apache Pre-fork mode to work better with PHP-FPM. This improves the server's concurrent processing capabilities and reduces response time.

• In the Nginx configuration file, add the following configuration to communicate with PHP-FPM:

  location ~ .php$ {
  fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  include fastcgi_params;
  }

  Copy after login

• In the Apache configuration file, add the following configuration To communicate with PHP-FPM:

  <FilesMatch .php$>
  SetHandler "proxy:unix:/var/run/php/php7.2-fpm.sock|fcgi://localhost/"
  </FilesMatch>

  Copy after login

3. Using Caching

• Use Drupal’s built-in caching system or install a third-party caching module , such as Redis or Memcached, to reduce database query and page rendering time.

• In Drupal's configuration file settings.php, add the following code to enable the built-in caching system:

  $conf['cache'] = 1;

  Copy after login

• In Drupal's configuration file settings.php, Add the following code to enable the Redis cache module:

  $conf['redis_client_host'] = '127.0.0.1';
  $conf['cache_backends'][] = 'sites/all/modules/redis/redis.autoload.inc';
  $conf['cache_default_class'] = 'Redis_Cache';
  $conf['cache_class_cache_form'] = 'DrupalDatabaseCache';
  

  Copy after login

• In Drupal's configuration file settings.php, add the following code to enable the Memcached cache module:

  $conf['cache_backends'][] = 'sites/all/modules/memcache/memcache.inc';
  $conf['cache_default_class'] = 'MemCacheDrupal';
  $conf['cache_class_cache_form'] = 'DrupalDatabaseCache';

  Copy after login

4. Other optimization suggestions

• Enable Drupal’s CSS and JS aggregation features to reduce HTTP requests and page load times. In Drupal's unified configuration file settings.php, add the following code:

  $config['system.performance']['css']['preprocess'] = true;
  $config['system.performance']['js']['preprocess'] = true;
  $config['system.performance']['cache']['page']['max_age'] = 3600;

  Copy after login
• Use efficient image compression and resizing methods, such as using image compression tools, using CDN, etc., to reduce the size of images and loading times.
• Regularly optimize Drupal's database to ensure database performance and response time.
• Use tools for performance testing and monitoring, such as ApacheBench, New Relic, etc., to determine the effect of optimization and the direction of further improvement.

Conclusion: By adjusting the configuration parameters of PHP-FPM, using the process manager, and using cache, the performance of the Drupal website can be greatly improved. The specific code examples given above can be used as a reference, but the actual optimization method needs to be adjusted and verified based on the specific conditions of the website. Applying these optimization methods to Drupal websites can make the website respond to requests faster and improve user experience.
