php-mbstring php-curl php-mysqli libnginx-mod-rtmp mariadb-server mariadb-client php-fpm memcached php-memcache

Желательно везде вместо php-... писать php8.0-..., потому что нынешний Raspberrian ставит по умолчанию php 7.4. Про memcache: сервер называется memcached, а плагин php-memcache, не php-memcached! Потому что такой есть тоже, но тяжелый, медленный и ненужный. Не забываем затем нахер apache2, который поставил php:

apt purge apache2

Настройка MYSQL, чтоб два раза не вставать

sudo mysql -u root

CREATE DATABASE my_base DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

GRANT ALL PRIVILEGES ON my_base.* TO lleo@localhost IDENTIFIED BY 'MyPassword' WITH GRANT OPTION;

SET @@SQL_MODE = REPLACE(@@SQL_MODE, 'STRICT_TRANS_TABLES', '');
SET @@SQL_MODE = REPLACE(@@SQL_MODE, 'STRICT_ALL_TABLES', '');
FLUSH PRIVILEGES;

Установить пароль:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'mypassword';

Добавить в /etc/mysql/my.cnf:

[mysqld]
sql_mode=NO_ENGINE_SUBSTITUTION

Перезапустить, чтобы сработало.

nginx

Простейший конфиг nginx для php /etc/nginx/sites-enabled/site.conf

server {

listen 80 default_server;

listen [::]:80 default_server;

server_name _;

index index.html index.htm index.php;

client_max_body_size 500M;

location / {

root /home/www;

try_files $uri /index.php?$args;

location ~ \.php$ {

fastcgi_split_path_info ^(.+\.php)(/.+)$;

try_files $fastcgi_script_name =404;

fastcgi_pass unix:/var/run/php/php-fpm.sock;

fastcgi_index index.php;

include fastcgi_params;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

client_max_body_size 500m;

client_body_buffer_size 128k;

proxy_connect_timeout 90;

proxy_send_timeout 90;

proxy_read_timeout 90;

proxy_buffer_size 4k;

proxy_buffers 4 32k;

proxy_busy_buffers_size 64k;

proxy_temp_file_write_size 64k;

}

}
}

Но php толком не заработает, пока в начало файла /etc/nginx/fastcgi_params не добавить строчку:

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Но всё это, напоминаю, только если вам нужен ещё и сервер. Для чипльдуктора не нужен.
