The document discusses optimizing a web server by using Nginx and PHP-FPM. It provides instructions on installing and configuring PHP-FPM to handle PHP processing and Nginx as a reverse proxy. Using this setup provides advantages over traditional Apache + modPHP configurations, including Nginx being asynchronous for better performance, built-in load balancing, caching, and other features.

4. PHP-FPM
● FastCGI Process Manager
● Implementación alternativa de PHP FastCGI
● Con funcionalidades adicionales utiles para sitios de
todos tamaños, en particular sitios muy activos
● Integrado en PHP desde PHP 5.4 en Nov 2011

6. PHP-FPM
● Gestión de procesos avanzada
● Posibilidad workers con uid/ambientes distintos
● ...y php.ini distintos
● Soporte de upload acelerado
● Slow log
● ...

17. Instalar PHP-FPM

18. Configurar PHP-FPM
user@server:~$ sudo vim /etc/php/7.1/fpm/
conf.d/ php­fpm.conf php.ini pool.d/
user@server:~$ sudo vim /etc/php/7.1/fpm/php.ini
[PHP]
;;;;;;;;;;;;;;;;;;;
; About php.ini ;
;;;;;;;;;;;;;;;;;;;
; PHP's initialization file, generally called php.ini, is responsible for
; configuring many of the aspects of PHP's behavior.
; PHP attempts to find and load this configuration from a number of locations.
; The following is a summary of its search order:

19. Configurar PHP-FPM
user@server:~$ sudo vim /etc/php/7.1/fpm/pool.d/www.conf
; Start a new pool named 'www'.
; the variable $pool can be used in any directive and will be replaced by the
; pool name ('www' here)
[www]
; …
user = www­data
group = www­data
; …
listen = /run/php/php7.1­fpm.sock
listen.owner = www­data
listen.group = www­data
; …
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.process_idle_timeout = 10s;

20. Configurar PHP-FPM
user@server:~$ sudo vim /etc/php/7.1/fpm/pool.d/www.conf
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.process_idle_timeout = 10s;
pm.max_requests = 500
access.log = log/$pool.access.log
slowlog = log/$pool.log.slow
request_slowlog_timeout = 0

21. Configurar PHP-FPM
user@server:~$ sudo vim /etc/php/7.1/fpm/pool.d/www.conf
;php_admin_value[sendmail_path] = /usr/sbin/sendmail ­t
­i ­f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm­php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M
En resumen: todo por defecto!

22. Configurar Nginx
- sudo apt-get install nginx-full
- sudo vim /etc/nginx/nginx.conf
user www­data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}

23. Configurar Nginx
- sudo apt-get install nginx-full
- sudo vim /etc/nginx/nginx.conf
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
# server_tokens off;

24. Configurar Nginx
- sudo apt-get install nginx-full
- sudo vim /etc/nginx/sites-available/default
server {
listen 80 default_server;
listen [::]:80 default_server;
index index.html index.htm index.nginx­debian.html;
server_name _;
location / {
try_files $uri $uri/ =404;
}

25. Configurar Nginx
- sudo apt-get install nginx-full
- sudo vim /etc/nginx/sites-available/default
server {
# ...
# pass the PHP scripts to FastCGI server
# listening on 127.0.0.1:9000
#
location ~ .php$ {
include snippets/fastcgi­php.conf;
# With php7.1­fpm:
fastcgi_pass unix:/run/php/php7.1­fpm.sock;
}

26. Configurar Nginx
- sudo service php-fpm restart
- sudo service apache2 stop (si tiene Apache)
- sudo service nginx restart

27. Ventajas
- Asíncrono (libevent)
- Balanceador de carga (directiva “upstream”)
- Reverse Proxy (caché)
- Soporte SSL completo
- Soporte moderación
- limit_conn / limit_conn_zone
- limit_rate
- limit_req / limit_req_zone
- max_conns (upstream)
- queue
- Compresión
