php - Nginx、PHP - 发生错误。抱歉，您要查找的页面目前不可用。请稍后再试

Question

当我访问 /usr/local/nginx-1.12.2/html 的 index.php 时出现错误。

An error occurred.
Sorry, the page you are looking for is currently unavailable.
Please try again later.

If you are the system administrator of this resource then you should check the error log for details.

Faithfully yours, nginx.

我的 nginx.conf 是这样的:

#cat conf/nginx.conf:

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm index.php;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }

    }

}

在我的 /usr/local/php-7.1.16/etc 中，php-fpm.conf 配置是这样的:

#cat php-fpm.conf

[global]
pid = /usr/local/php-7.1.16/var/run/php-fpm.pid
error_log = /usr/local/php-7.1.16/var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 60
pm.start_servers = 30
pm.min_spare_servers = 30
pm.max_spare_servers = 60
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log

我的 php-fpm 正在运行。我可以使用 ps -ef | grep php-fpm 来检查。那里有多个进程。

我的 index.php 只是一个 phpinfo():

index.php:

<?php

  ini_set("display_errors","On");  
  error_reporting(E_ALL);    

  echo phpinfo(); 
?>

EDIT-1

在我的 nginx 的 error.log 中:

2018/06/25 09:36:02 [error] 12360#0: *13338 connect() failed (111: Connection refused) while connecting to upstream, client: 118.113.137.192, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "101.103.23.5"

EDIT-2

谢谢 Dan，我将 fastcgi_pass 127.0.0.1:9000 更改为:

fastcgi_pass   unix:/tmp/php-cgi.sock;

但是当我访问 index.php 时，出现 File not found. 错误。

Answer 1

你为 fpm 指定一个 unix 套接字来监听:

listen = /tmp/php-cgi.sock

但是在 nginx 中你指定一个 IP 地址:

fastcgi_pass   127.0.0.1:9000;

---

仅配置 IP 或仅配置 Unix Socket:

fastcgi_pass   unix:/tmp/php-cgi.sock;

或

listen = 127.0.0.1:9000

关于您的编辑 2:

尝试添加这个参数:

fastcgi_split_path_info ^(.+\.php)(/.+)$;

而且您的 SCRIPT_FILENAME 看起来也不正确，您指定的文件夹很可能不存在 (/scripts)。

试试这个动态路径:

fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
