紧急：Ubuntu 服务器升级后 Nginx 崩溃

之前尝试过将 Nginx 从 1.14 升级到 1.14.1。但在 apt-get upgrade 中我得到了：

mysite systemd[1]: Starting A high performance web server and a        reverse proxy server...
mysite nginx[31861]: nginx: [emerg] duplicate upstream  "fastcgi_backend" in /etc/nginx/sites-enabled/mysite.conf.save:1
mysite nginx[31861]: nginx: configuration file  /etc/nginx/nginx.conf test failed
mysite systemd[1]: nginx.service: Control process exited,  code=exited status=1
mysite systemd[1]: Failed to start A high performance web server     and a reverse proxy server.
mysite systemd[1]: nginx.service: Unit entered failed state.
mysite systemd[1]: nginx.service: Failed with result 'exit-code'.
dpkg: error processing package nginx-full (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of nginx:
nginx depends on nginx-full (<< 1.14.1-0+xenial0.1~) | nginx-light (<<   1.14.1-0+xenial0.1~) | nginx-extras (<< 1.14.1-0+xenial0.1~); however:
Package nginx-full is not configured yet.
Package nginx-light is not installed.
Package nginx-extras is not installed.
nginx depends on nginx-full (>= 1.14.1-0+xenial0) | nginx-light (>=  1.14.1-0+xenial0) | nginx-extras (>= 1.14.1-0+xenial0); however:
Package nginx-full is not configured yet.
Package nginx-light is not installed.
Package nginx-extras is not installed.

我在 mysites.conf 文件中有这些内容：

upstream fastcgi_backend {
server   127.0.0.1:9000;
#server unix:/run/php/php7.2-fpm.sock;
}

server {
listen 80;
server_name mysite.com;
return 301 https://www.example.com$request_uri;
}

server {
listen 80 default_server;
server_name www.example.com; # dev.www.example.com;
root   /home/public_html;

#check http_x_forwarded_proto value that comes from load balancer
set $my_http "http";
set $my_ssl "off";
set $my_port "80";

if ($http_x_forwarded_proto = "https") {
  set $my_http "https";
  set $my_ssl "on";
  set $my_port "443";
}

    try_files $uri $uri/ @handler;
}

location @handler {
    rewrite / /index.php;
}

#location = /js/index.php/x.js {
#    rewrite ^(.*\.php)/ $1 last;
#}

location ~ \.php {
    expires  off;
  # fastcgi_pass   fastcgi_backend;

    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include fastcgi_params;
    fastcgi_param REMOTE_ADDR $http_x_real_ip;
}
}

据我检查，只有这几行：

upstream fastcgi_backend {
server   127.0.0.1:9000;
#server unix:/run/php/php7.2-fpm.sock;
}

我的网站坏了。有人能帮忙吗？

您upstream fastcgi_backend定义了两次： inmysites.conf和 in wallpapershop.gr.conf.save。因此您收到错误消息nginx: [emerg] duplicate upstream "fastcgi_backend"。

通过删除第二个配置文件（按照 Michael Hampton 的建议），您解决了这个问题。
