This document discusses using Nginx as a web server with PHP. It provides configuration examples for using Nginx with PHP-FPM to pass PHP requests. Benchmarks show Nginx performs better than Apache. It also discusses using Nginx as a reverse proxy cache, and provides configuration examples to cache content and pass caching controls from PHP.

10. How to use
Nginx
with PHP?

11. 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

12. 【 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;
}
}

13. 【 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

19. Reverse
proxy Cache

20. $ ab -n 1000 -c 100
AWS t1.micro
Nginx, php with APC
(WordPress トップページ)
Requests per second: 141.24 [#/sec] (mean)
Time per request: 708.007 [ms] (mean)
Connection Times Total: 636 [ms] (mean)

21. 【 nginx.conf の例 】
http {
:
proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2
keys_zone=czone:32m max_size=256m inactive=1440m;
proxy_temp_path /var/cache/nginx/proxy_temp;
proxy_cache_key "$scheme:/ /$host$request_uri";
proxy_set_header Host $host;
proxy_set_header Remote-Addr $remote_addr;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Accept-Encoding "";
proxy_connect_timeout 5;
proxy_send_timeout 10;
proxy_read_timeout 120;
proxy_cache_lock on;
proxy_cache_lock_timeout 5s;
upstream backend {
server unix:/var/run/nginx-backend.sock;
}
:
}

22. server {
listen 80 default;
server_name _;
root /path/to/app;
index index.php index.html index.htm;
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;
}
}

23. server {
listen unix:/var/run/nginx-backend.sock;
server_name _;
root /path/to/app;
index index.php index.html index.htm;
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";
}
}

24. 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);
?>
