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;
    }
}
