php - 服务器恢复后 502 Bad Gateway Nginx

Question

所以我有一个 Ubuntu 服务器，我正试图从备份中恢复它。当出现虚拟 PHP 版本页面时，我得到 502 Bad Gateway。我尝试过什么来修复它？很多事情，包括这个相关问题的答案 - nginx 502 bad gateway

这是我在 Ubuntu 上的默认配置

server {
listen 80;
#   listen [::]:81 ipv6only=on default_server;

root /var/www/html;
index index.php index.html index.htm;

server_name localhost;

location ~* \.(js|css|png|jpg|jpeg|gif|ico|html)$ {
        expires max;
}


location / {
    try_files $uri $uri.php $uri.php/$args /index.php?q=$uri&$args $uri/ =404;
    index index.php index.html index.htm;
    rewrite ^(.*)$ /$1.php;
}

location /phpmyadmin {
  index index.php;
    try_files $uri $uri/ =404;
    auth_basic "Admin Login";
    auth_basic_user_file /etc/nginx/pma_pass;
}

error_page 404 /404.html;

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

location ~ \.php$ {
    try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
}


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

编辑: 这是我认为是日志的相关部分

这是我运行 ps aux | 时的结果grep php-fpm:

这是我的 php-fpm.conf 中未注释的内容

[global]
; Pid file
; Note: the default prefix is /var
; Default Value: none
pid = /var/run/php5-fpm.pid

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Note: the default prefix is /var
; Default Value: log/php-fpm.log
error_log = /var/log/php5-fpm.log


;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ; 
;;;;;;;;;;;;;;;;;;;;

; To configure the pools it is recommended to have one .conf file per
; pool in the following directory:
include=/etc/php5/fpm/pool.d/*.conf

这是我的 www.conf 中未注释的内容:

listen = 127.0.0.1:9000
listen.owner = www-data  
listen.group = www-data
listen.mode = 0660
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

我尝试访问 index.php 后的 nginx 日志:

[error] 29393#0: *23 connect() failed (111: Connection refused) while connecting to upstream, client: [Computer IP Address], server: [Subdomain.domain.com], request: "GET /favicon.ico HTTP/1.1", upstream:"http://127.0.0.1:8080/favicon.ico", host: [Server IP], referrer: "http://[Server IP]/index.php"

Answer 1

所以我检查了我的 nginx 配置并发现了这些行:

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

然后我去了 /etc/nginx/conf.d/*.conf 并看到在 servers.conf 文件中，有一个子配置我计划使用但不会再使用的域，所以我删除了它。这是问题的主要部分，因为 nginx 首先查看此配置，这就是错误包含此子域的原因。

至于 php 问题，我将我的配置切换为 fastcgi_pass unix:/run/php/php7.0-fpm.sock;，这似乎解决了问题。
