4、nginx设置FastCGI代理-阅读官方文档

官网：Beginner’s Guide

翻译部分：Setting Up FastCGI Proxying

tips: FastCGI是一个协议

开始！

---

nginx can be used to route requests to FastCGI servers which run applications built with various frameworks and programming languages such as PHP.

 nginx可以用来路由请求到用各种各样的框架和编程语言建立的FastCGI服务器上。

---

The most basic nginx configuration to work with a FastCGI server includes using the fastcgi_pass directive instead of the proxy_pass directive, and  fastcgi_param directives to set parameters passed to a FastCGI server.

 能够和FastCGI服务器工作最基本的nginx配置包括fastcgi_pass，fastcgi_param指令。

fastcgi_param设置传个FastCGI服务器的参数。

---

Suppose the FastCGI server is accessible on localhost:9000.

 假设在localhost:9000上可以访问到FastCGI服务器。

---

Taking the proxy configuration from the previous section as a basis, replace the proxy_pass directive with the fastcgi_pass directive and change the parameter to localhost:9000.

将之前那些部分的demo：proxy_pass http://localhost:8080/; 修改成下面这样

 fastcgi_pass localhost:9000;

---

In PHP, the SCRIPT_FILENAME parameter is used for determining the script name, and the QUERY_STRING parameter is used to pass request parameters.

 在PHP中，SCRIPT_FILENAME参数用来决定脚本名称

 QUERY_STRING参数用来传递请求参数

---

The resulting configuration would be:

server {
    location / {
        fastcgi_pass  localhost:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param QUERY_STRING    $query_string;
    }

    location ~ \.(gif|jpg|png)$ {
        root /data/images;
    }
}

 最终配置文件长这样。

---

This will set up a server that will route all requests except for requests for static images to the proxied server operating on localhost:9000 through the FastCGI protocol.

 上面的配置会设置一个服务器，它会通过FastCGI协议，路由除静态文件请求以外的请求到跑在localhost:9000 上的被代理服务器。
