使用 NGINX 对 PHP 脚本进行多个同时请求

Question

我有一个运行 NGINX 和 PHP 的网络服务器，有一个非常基本的多客户端测试。

<?php
    if(isset($_GET['query'])) {
        echo "HELLO MY NAME IS WEBSERVER";
    }
    if(isset($_GET['sleep'])) {
        sleep(10);
    }
?>

如果我运行http://servername.com/index.php?query，我会得到即时响应。

如果我同时运行 ?sleep 然后 ?query，则 ?query 似乎会排队直到 ?sleep 完成。

这种情况发生在多个客户端上。客户端A可以请求?sleep，这会影响客户端B的?query请求。客户端 B 是一台完全不同的机器。

有没有任何方法可以调整 php.ini 或我的 nginx 配置以允许生成单独的 php 工作进程（或类似的东西？）

编辑：对于一些背景知识，这是我的配置。

nginx.conf：

    location ~ \.php$ {
            fastcgi_pass   127.0.0.1:9123;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
    }

fastgci_params：

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REQUEST_SCHEME     $scheme;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

php 执行（runphp.bat）：

set PATH=%cd%\php;%PATH%
start %cd%\php\php-cgi.exe -b 127.0.0.1:9123

编辑2：好的，看来我需要PHP-FPM，它在Windows上不可用：

It is important to note that FPM is not built with the windows binaries.  Many of the guides you may find online rely on php-cgi.exe.  Unfortunately they call it FPM but this is incorrect!

The executable php-cgi.exe that is bundled with the windows binaries is a FastCGI interface but it is *not* FPM (Fastcgi Process Manager).  php-cgi.exe does not have multi-threading or concurrent request support, nor support for any of the FPM configuration options.

因此，作为一种解决方法，我正在尝试多个 php 服务器/进程方法：

upstream php {
    server  127.0.0.1:9000;
    server  127.0.0.1:9001;
    server  127.0.0.1:9002;
    server  127.0.0.1:9003;
}

location ~ \.php$ {
    fastcgi_pass   php;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

然而，NGINX 在此配置中根本不会启动。它似乎不想接受任何“上游 php {}”

有任何想法吗？

谢谢

根据编辑，我认为 PHP-FPM 在 Windows 中不可用。但是，可以通过在不同端口上生成多个 PHP 进程并配置 NGINX 在它们之间进行负载平衡来绕过此问题。

我的“RunPHP.bat”脚本：

set PATH=%cd%\php;%PATH%
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9100
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9101
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9102
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9103

我的 nginx.conf （仅限 php 位）：

http {

    upstream php_farm {
        server 127.0.0.1:9100 weight=1 max_fails=1 fail_timeout=1s;
        server 127.0.0.1:9101 weight=1 max_fails=1 fail_timeout=1s;
        server 127.0.0.1:9102 weight=1 max_fails=1 fail_timeout=1s;
        server 127.0.0.1:9103 weight=1 max_fails=1 fail_timeout=1s;
    }

    server {
        location ~ \.php$ {
                fastcgi_pass   php_farm;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                include        fastcgi_params;

    }

}
