How to optimize PHP-FPM performance to improve the response speed of the website

With the rapid development of the Internet, the performance of the website has become more and more important. As a common server-side scripting language, PHP also faces the challenge of performance optimization. This article will introduce how to improve the response speed of the website by optimizing PHP-FPM, and give specific code examples.

PHP-FPM (FastCGI Process Manager) is a FastCGI manager for PHP, which is an improved version of PHP-FastCGI. It manages FastCGI processes to provide better performance and better scalability. Here are some ways to optimize the performance of PHP-FPM:

1. Adjust the process management configuration

The performance of PHP-FPM is mainly affected by the process management configuration. You can make PHP-FPM run more efficiently by adjusting the following parameters:

• pm.max_children: Specifies the maximum number of child processes in the PHP-FPM process pool. According to the server configuration and requirements, this value can be increased appropriately to improve concurrent processing capabilities.
• pm.start_servers: Specify the number of pre-created child processes when PHP-FPM starts. Depending on the load on the server, this value can be adjusted appropriately to balance resource utilization and response speed.
• pm.min_spare_servers and pm.max_spare_servers: Specify the minimum and maximum number of idle child processes in the PHP-FPM process pool respectively. Depending on the load on the server, these two values ​​can be adjusted appropriately to avoid too many idle processes or not enough idle processes.

The following is an example PHP-FPM configuration:

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

2. Accelerated using Opcache

Opcache is included in PHP 5.5 and above A feature enabled by default, it can cache the bytecode of PHP scripts, reduce the cost of repeated compilation, and thereby increase the execution speed of PHP scripts.

In the php.ini file, you can configure the parameters of Opcache, for example:

[opcache]
opcache.enable = 1
opcache.memory_consumption = 128
opcache.max_accelerated_files = 4000
opcache.validate_timestamps = 0

3. Use cache

For some relatively stable data, you can Use caching to reduce frequent queries to the database, thereby improving website responsiveness. Common caching technologies include Redis, Memcached, etc. The following is a code example that uses Redis as a cache:

$redis = new Redis();
$redis->connect('localhost', 6379);

$key = 'cache_key';
$data = $redis->get($key);

if (!$data) {
    // 数据缓存不存在，从数据库查询数据
    $data = // 从数据库查询数据的代码

    // 将数据存入缓存
    $redis->set($key, $data);
}

// 使用数据
// ...

4. Enable dynamic expansion of PHP-FPM

PHP-FPM supports dynamic expansion, and some can be enabled according to actual needs Commonly used extensions, such as: opcache.so, apcu.so, etc. By enabling these extensions, you can improve PHP's performance.

In the php.ini file, you can use the extension=module.so form to enable extensions, for example:

extension=opcache.so
extension=apcu.so

Through the above method, you can optimize the performance of PHP-FPM and improve the website responding speed. However, it should be noted that the specific optimization methods and parameter configurations need to be adjusted and tested according to the actual situation of the server to obtain the best performance improvement effect.
