This article will introduce the installation and use of PHP-FPM to help developers quickly master this important component.

1. Install PHP-FPM

1.1 Install PHP

Before installing PHP-FPM, you need to install PHP first. PHP has many different versions and extensions, and you can choose different versions of PHP according to your project needs. In general, you can install PHP through the following command:

sudo apt-get install php
Copy after login

2. Configure PHP-FPM

Before using PHP-FPM, some configurations are required. Generally, configuration can be done in the following files:

/etc/php/7.2/fpm/php.ini
/etc/php/7.2/fpm/pool.d/www.conf
Copy after login

Among them, the php.ini file is the main configuration file of PHP, in which some basic parameters of PHP can be set; ## The #www.conf file is the configuration file of PHP-FPM, in which you can set some parameters of PHP-FPM, such as the number of processes, the maximum number of connections, etc.

The following is an example content of a

www.conf file:

; Start a new pool named 'www'.
[www]

; The user and group the PHP-FPM process will run as.
user = www-data
group = www-data

; The address on which to accept FastCGI requests.
listen = /run/php/php7.2-fpm.sock

; Set permissions on the socket to allow the web server to access it.
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

; The number of child processes to spawn.
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 2
pm.max_spare_servers = 5
Copy after login
The above configuration is a relatively simple example and can be modified according to the actual situation.

3. Using PHP-FPM

Using PHP-FPM can be done through the FastCGI protocol. The following is an example configuration using PHP-FPM:

location / {
    try_files $uri $uri/ /index.php?$args;
}

location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
Copy after login
The above configuration will URI Requests ending in .php are forwarded to the PHP-FPM process and communicate using the FastCGI protocol.
