【PHP】Docker+Nginx+PHP环境部署报FastCGI sent in stderr: “Primary script unknown“ while reading...错

多容器搭建 php-fpm + nginx, 在测试 nginx 的配置是否成功与 fpm 连通时，访问 url,

每次都报 File not found.

nginx 的日志如下：

核心的问题： FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream

docker logs php-fpm 的日志如下：

nginx 的日志如下： 

server {
    listen       80;
    server_name  localhost;
    root /usr/share/nginx/html/;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        fastcgi_pass   php_180227_7.1.0:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    location ~ /\.ht {
        deny  all;
    }
}

nginx 的共享目录如下(/home/docker_lnmp/nginx/www:/usr/share/nginx/html)： 

php 的共享目录如下(/home/docker_lnmp/nginx/www:/var/www/html)： 

nginx 配置文件 config 中

fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

要换成

fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;

不然 php fastcgi解析不了目录
