我刚刚在我的服务器上安装了一个ssl certfificate。 它工作了大约一个小时。 现在该网站没有加载。 当我去做nginx -t我得到这个错误：
nginx: [emerg] duplicate upstream "app_server" in /etc/nginx/sites-enabled/rails.save:1 nginx: configuration file /etc/nginx/nginx.conf test failed 这是什么在我的rails.save文件中：
upstream app_server { server unix:/var/run/unicorn.sock fail_timeout=0; } server { listen 80; server_name example.com; return 301 https://www.exammple.com$request_uri; } server { listen 80; server_name www.example.com; rewrite ^(.*) https://www.example.com$1 permanent; } server { listen 443 ssl; root /home/rails/example/public; server_name www.example.com; ssl_certificate /example.com.chained.crt; ssl_certificate_key /example.com.key; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; ssl_ciphers AES256+EECDH:AES256+EDH:!aNULL; index index.htm index.html; location / { try_files $uri/index.html $uri.html $uri @app; } location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|f$ try_files $uri @app; } location @app { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://app_server; } }
这是我的nginx.conf文件

根据评论所采取的有益措施：
upstreamconfiguration指令。 proxy_pass http://app_server; 同 proxy_pass http://unix:/var/run/unicorn.sock; 。
