How to use PHP-FPM optimization to improve the performance of WordPress website?
Overview:
WordPress is one of the most widely used content management systems currently. However, as website traffic increases, performance problems gradually appear. PHP-FPM is a tool for managing and running PHP FastCGI processes, which can improve WordPress performance through some optimization methods. This article will introduce in detail how to use PHP-FPM optimization to improve the performance of WordPress websites and provide specific code examples.
We can configure it in the php-fpm.conf file. The following are some commonly used parameter configuration examples:
pm.max_children = 100 pm.start_servers = 20 pm.min_spare_servers = 10 pm.max_spare_servers = 30 pm.max_requests = 500
Among them, pm.max_children
represents the maximum number of PHP processes, pm.start_servers
represents the start of the PHP process pool Quantity, pm.min_spare_servers
and pm.max_spare_servers
respectively represent the minimum and maximum number of idle processes in the PHP process pool, pm.max_requests
represents the requests processed by each process Quantity limit.
We can enable OPcache by modifying the php.ini file and perform related configurations. The following are some commonly used configuration examples:
opcache.enable = 1 opcache.memory_consumption = 128 opcache.interned_strings_buffer = 8 opcache.max_accelerated_files = 4000 opcache.validate_timestamps = 0
Among them, opcache.enable
indicates whether to enable OPcache, opcache.memory_consumption
indicates the memory consumption of OPcache, opcache .interned_strings_buffer
indicates the size of the string cache, opcache.max_accelerated_files
indicates the maximum number of accelerated files, opcache.validate_timestamps
indicates whether to enable timestamp verification.
We can enable Redis cache by adding the following code in the wp-config.php file:
define( 'WP_REDIS_HOST', '127.0.0.1' ); define( 'WP_REDIS_PORT', 6379 ); define( 'WP_REDIS_DATABASE', 0 ); define( 'WP_REDIS_TIMEOUT', 5 ); define( 'WP_REDIS_PASSWORD', 'your_password' );
Among them, WP_REDIS_HOST
and WP_REDIS_PORT
represents the host and port of Redis respectively, WP_REDIS_DATABASE
represents the Redis database, WP_REDIS_TIMEOUT
represents the timeout period for connecting to Redis, WP_REDIS_PASSWORD
represents the Redis password (optional) ).
We can modify the Nginx configuration file and forward the request to PHP-FPM for processing. The following is a simple Nginx configuration example:
server { listen 80; server_name example.com; location / { try_files $uri $uri/ /index.php?$args; } location ~ .php$ { fastcgi_pass unix:/var/run/php/php7.4-fpm.sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
In this configuration, we forward all PHP requests to PHP-FPM for processing.
Conclusion:
By optimizing and configuring PHP-FPM, we can improve the performance of the WordPress website. This article provides some basic optimization methods and sample code, hoping to be helpful to everyone. Of course, specific optimization strategies need to be adjusted and optimized based on actual conditions.
