How to build a high-performance php server

With the development of the Internet, more and more websites and applications choose to use PHP as the development language. For the high-performance requirements of PHP website operation, the performance and configuration of the server are particularly important. In this article, we will introduce how to set up a high-performance PHP server.

First of all, we need to choose a server. Generally speaking, it is very important to choose a cloud server or independent server with reasonable configuration. Some people think that it is enough to choose a virtual host, but due to resource sharing, virtual hosts cannot meet the needs of high traffic and high concurrency. Therefore, it is more appropriate for us to choose a physical server with higher configuration, which must have at least 16GB of memory and a quad-core CPU.

Secondly, we need to install and configure Nginx or Apahce web server. Both web servers can handle PHP requests and work very well in terms of performance. When choosing a Web server, we need to consider the following points:

1. Apache Web Server

Apache is a powerful and stable Web server, but because of its All PHP modules need to be preloaded, so performance bottlenecks will occur in high-concurrency environments.

2. Nginx Web Server

Nginx is an open source high-performance web server and takes up less system resources than Apache. It can effectively handle high concurrent traffic, so it is increasingly used in PHP website configurations.

When choosing a Web server, you can choose it according to your actual needs.

Next, we need to install the PHP interpreter and cache extension. Such as PHP-FPM and APCu extensions. PHP-FPM is PHP's FastCGI process manager, which can pass PHP requests to the back-end PHP interpreter, thereby improving the server's processing performance.

APCu is a PHP memory cache extension that caches PHP scripts and objects in server memory, thereby reducing the compilation and parsing time of PHP scripts and speeding up the processing of PHP applications.

If your server is based on Debian/Ubuntu or CentOS series systems, you can use the following commands to install PHP-FPM and APCu extensions.

For Debian/Ubuntu series systems:

$ sudo apt-get install php-fpm php-apcu

For CentOS series systems:

$ sudo yum install php-fpm php-apcu

After we install the PHP-FPM and APCu extensions, we need to modify the configuration files php.ini and php-fpm.conf files.

In the php.ini file, we need to add the following configuration to enable the APCu cache extension.

extension=apcu.so

In the php-fpm.conf file, we need to modify the following configuration.

listen = /var/run/php-fpm/php-fpm.sock
listen.backlog = 1024

pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35

Actually, the configuration here needs to be adjusted according to the server configuration and actual needs. Here is just a basic example for your reference.

Finally, we need to install and configure the cache service. It is recommended to use Redis or Memcached to cache MySQL database query results to reduce database access. Redis is an in-memory database, while Memcached is a fast in-memory object caching system.

The following are the detailed steps to configure Redis.

Install Redis on the server.

$ sudo apt-get install redis-server

To use the PHP extension of Redis in PHP, you can add the following configuration to the php.ini file to enable the Redis extension.

extension=redis.so

You can use Redis as a PHP plug-in to provide connection pooling and connection pooling support for applications.

The above are the steps required to build a high-performance PHP server, which involves many details and configurations and needs to be adjusted according to the actual situation. Through the above operations, you will be able to improve server performance and support for high traffic and high concurrency, making your PHP applications run faster and more stably.
