How to use PHP-FPM to optimize and improve the performance of Phalcon applications

Introduction: Phalcon is a high-performance PHP framework, which can further improve application performance when combined with PHP-FPM . This article will introduce how to use PHP-FPM to optimize the performance of Phalcon applications and provide specific code examples.

1. What is PHP-FPM

PHP-FPM (PHP FastCGI Process Manager) is a PHP process manager independent of the web server. It can manage and process PHP scripts and provides Better performance and resource utilization.

2. Why use PHP-FPM

1. Multi-process management: PHP-FPM can manage multiple PHP processes. Each process runs independently and can handle multiple requests at the same time. Compared with PHP's built-in server, PHP-FPM has higher concurrency processing capabilities.
2. Resource control: PHP-FPM can allocate resources, such as memory and CPU, to each PHP process to optimize performance and increase throughput. At the same time, PHP-FPM also supports connection pools and thread pools to effectively reuse resources and reduce resource waste.
3. Dynamic adjustment: PHP-FPM can dynamically adjust the number and configuration of PHP processes according to actual request volume and load conditions to adapt to different business scenarios.

3. Configure PHP-FPM

The following is a simple PHP-FPM configuration file example (php-fpm.conf):

[global]
pid = /var/run/php-fpm.pid
error_log = /var/log/php-fpm.log
log_level = error

[www]
listen = 127.0.0.1:9000
user = www-data
group = www-data
pm = dynamic
pm.max_children = 10
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

This configuration file , [global] is the global configuration, [www] is the configuration for the PHP-FPM process pool (pool).

Among them, listen specifies the address and port that PHP-FPM listens on, and user and group specify the running user and group of the PHP-FPM process.

The pm parameter controls the process management method of PHP-FPM. pm.max_children specifies the maximum number of child processes. pm.start_servers, pm.min_spare_servers and pm.max_spare_servers control the child processes at startup and idle time. quantity.

4. Use PHP-FPM to optimize the performance of Phalcon applications

1. Configure Nginx

First, add the following code to the Nginx configuration file:

location ~ .php$ {
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    fastcgi_param  PHP-FPM_CONNECT_TIMEOUT 3;
    include        fastcgi_params;
}

This code passes the request to PHP-FPM through fastcgi_pass, and sets the SCRIPT_FILENAME and PHP-FPM_CONNECT_TIMEOUT parameters.

2. Enable Phalcon extension

In Phalcon’s configuration file, ensure that the Phalcon extension is enabled:

extension=phalcon.so

3. Subprocess Management

In Phalcon applications, you can use the process management function provided by PHP-FPM to optimize performance.

First, in the application's entry file (usually public/index.php), add the following code:

$app = new PhalconMvcApplication($di);
$di->setShared('app', $app);

$app->handle();

Next, in the PHP-FPM configuration file, add the pm parameter The value is adjusted to a suitable size to suit the actual situation. Adjustments can be made by monitoring actual request volume.

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

This configuration will allow PHP-FPM to run up to 50 child processes at the same time, while ensuring that at least 10 child processes are idle waiting for requests.

4. Caching and optimizing SQL queries

Phalcon provides a caching mechanism that can cache the results of frequent queries in memory to reduce database access. Caching can be enabled by setting the caching parameters of the service container.

In addition, the performance of database queries can be improved by optimizing SQL query statements and using appropriate indexes. Phalcon provides a variety of query builders and ORM tools to facilitate SQL queries and relational object mapping.

5. Summary

By using PHP-FPM, we can better manage and control the PHP process and improve the performance of Phalcon applications. By configuring PHP-FPM and Nginx, as well as optimizing SQL query and caching technology, the performance and throughput of the application can be further improved.

However, the configuration of PHP-FPM needs to be adjusted according to the actual situation. It is recommended to optimize based on the actual load and request volume. At the same time, attention should be paid to monitoring and tuning SQL queries and rational use of caching technology to improve application response speed and performance.
