How to use
Nginx
with PHP?

Apache の mod_php のように
Nginx に直接組み込むことは
できない

→fast CGI ( php-fpm ) で

【 nginx.conf の例】
server {
listen 80 default;
server_name _;
root /path/to/app;
index index.php index.html index.htm;
charset utf-8;

location ~ .php$ {
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME
$document_root$fastcgi_script_name;
include fastcgi_params;
}
}

【 php-fpm.conf の例】
[www]
listen = /var/run/php-fpm.sock
listen.owner = nginx
listen.group = nginx
listen.mode = 0666

user = nginx
group = nginx

pm = dynamic
pm.max_children = 15
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 7

【 nginx.conf の例】
http {

proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2

upstream backend {
server unix:/var/run/nginx-backend.sock;
}
:
}

server {
listen 80 default;
server_name _;
root /path/to/app;

location ~* .(js|css|html?|xml|jpe?g|gif|png|swf|wmv|ﬂv|ico)$ {
expires 365d;
}

location / {
set $do_not_cache 0;
if ($request_method = POST) {
set $do_not_cache 1;
}
proxy_no_cache $do_not_cache;
proxy_cache_bypass $do_not_cache;
proxy_redirect off;
proxy_cache czone;
proxy_cache_key "$scheme://$host$request_uri$is_args$args$mobile";
proxy_cache_valid 200 0m;
proxy_pass http://backend;
}
}

server {
listen unix:/var/run/nginx-backend.sock;
server_name _;
root /path/to/app;
charset utf-8;

gzip off;
gzip_vary off;

location ~ .php$ {
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME
$document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_pass_header "X-Accel-Redirect";
fastcgi_pass_header "X-Accel-Buffering";
fastcgi_pass_header "X-Accel-Charset";
fastcgi_pass_header "X-Accel-Expires";
fastcgi_pass_header "X-Accel-Limit-Rate";
}
}

Reverse Proxy にキャッシュ
させる時間を PHP で制御
<?php
header('X-Accel-Expires: '. 60 * 60 * 24);
?>
