Nginx 安装说明（Nginx Installation Notes）¶
Nginx 是一个免费的，开源的高性能的Http服务器和反向代理服务器，同样也可作为IMAP/POP3代理服务器。不同于传统的服务器，Nginx 不依赖线程去处理请求。相反，它使用一个高扩展的事件驱动（异步）架构。 这种架构对系统资源的消耗很低，但更重要的是，承载了非常高的负载，并发能力很强。
PHP-FPM (FastCGI 进程管理器)通常用来允许 Nginx 来处理PHP文件。到了如今，PHP-FPM 已经捆绑在所有的PHP发行版中。Phalcon + Nginx + PHP-FPM 提供了一套强大的工具集，为你的PHP应用提供最强大性能。
Niginx 下配置 Phalcon（Configuring Nginx for Phalcon）¶
下面是nginx可以合Phalcon配合使用的大概配置：
基础配置（Basic configuration）¶
使用 $_GET[‘_url’] 作为 URLs的源：
server {
listen 80;
server_name localhost.dev;
root /var/www/phalcon/public;
index index.php index.HTML index.htm;
charset utf-8;
location / {
try_files $uri $uri/ /index.php?_url=$uri&$args;
}
location ~ \.php {
fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
fastcgi_index /index.php;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location ~ /\.ht {
deny all;
}
}
使用 $_SERVER[‘REQUEST_URI’] 作为 URLs的源：
server {
listen 80;
server_name localhost.dev;
root /var/www/phalcon/public;
index index.php index.html index.htm;
charset utf-8;
location / {
try_files $uri $uri/ /index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index /index.php;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location ~ /\.ht {
deny all;
}
}
专属实例（Dedicated Instance）¶
server {
listen 80;
server_name localhost;
charset utf-8;
#access_log /var/log/nginx/host.access.log main;
location / {
root /srv/www/htdocs/phalcon-website/public;
index index.php index.html index.htm;
# if file exists return it right away
if (-f $request_filename) {
break;
}
# otherwise rewrite it
if (!-e $request_filename) {
rewrite ^(.+)$ /index.php?_url=$1 last;
break;
}
}
location ~ \.php {
# try_files $uri =404;
fastcgi_index /index.php;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location ~* ^/(css|img|js|flv|swf|download)/(.+)$ {
root /srv/www/htdocs/phalcon-website/public;
}
}
使用 Host 配置（Configuration by Host）¶
And this second configuration allow you to have different configurations by host:
server {
listen 80;
server_name localhost;
root /var/www/$host/public;
access_log /var/log/nginx/$host-access.log;
error_log /var/log/nginx/$host-error.log error;
index index.php index.html index.htm;
try_files $uri $uri/ @rewrite;
location @rewrite {
rewrite ^(.*)$ /index.php?_url=$1;
}
location ~ \.php {
# try_files $uri =404;
fastcgi_index /index.php;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location ~* ^/(css|img|js|flv|swf|download)/(.+)$ {
root /var/www/$host/public;
}
location ~ /\.ht {
deny all;
}
}
