我已经为rails应用程序和nginx上游指令设置了一个puma服务器，但它没有正确路由。
我在乌布努图22.10

我的彪马配置文件如下

environment rails_env

if rails_env == "production"

    # Change to match your CPU core count
    workers 2

    # Min and Max threads per worker
    threads 1,2

    app_dir = File.expand_path("../..", __FILE__)

我将puma设置为systemctl服务：

而且端口正在监听，用sudo ufw allow 9292/tcp打开（我稍后会关闭它，我只是打开它来调试。

我可以转到kapelner.com:9292，网页服务没有错误（保存一些资产文件和其他预期的东西，因为它们被配置为通过nginx运行，如您将在下面看到的）。Puma和rails分别将相应的日志记录到以下三个文件：

root@kapelner-gradesly:~/deploy/gradeportal/current/log# ls -lh
total 45M
-rw-rw-r-- 1 root root    0 Jul 18 11:52 development.log
-rw-rw-r-- 1 root root  43M Jul 18 11:55 production.log
-rw-r--r-- 1 root root  377 Jul 18 11:54 puma.stderr.log
-rw-r--r-- 1 root root 2.2M Jul 18 11:54 puma.stdout.log

型
现在回到问题上...
我有nginx v1.22

root@kapelner-gradesly:~/deploy/gradeportal/current# nginx -version
nginx version: nginx/1.22.0 (Ubuntu)

也作为systemctl服务运行：

配置文件 checkout

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

我的nginx配置如下：

正如你所看到的，我以前尝试过“袜子”方法，也没有运气。下面是我的附加配置文件：

root@kapelner-gradesly:~# cat /etc/nginx/conf.d/kapelner.conf
server {
  listen 80;
  server_name kapelner.com *.kapelner.com;
  return 301 https://$host$request_uri;
}

server {
       listen   443 ssl;

       location @app {
          proxy_pass https://app;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header Host $http_host;
          proxy_redirect off;
        }

        root /root/deploy/gradeportal/current/public;
        server_name kapelner.com *.kapelner.com;
        #index index.htm index.html;
        try_files $uri/index.html $uri @app;

        access_log /var/log/nginx/kapelner_access.log;
        error_log /var/log/nginx/kapelner_error.log;

        location / {

                rewrite ^(.*)$ /kapelner$1 break;
        }
}

型
我也试过注解掉location块，但也没有成功。
问题是我在访问kapelner.com时收到“404未找到错误”。
在查看nginx日志时，我发现：

root@kapelner-gradesly:/var/log/nginx# cat /var/log/nginx/kapelner_access.log
...
72.226.69.230 - - [18/Jul/2023:12:23:22 -0400] "GET / HTTP/1.1" 404 564 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36"

型
错误的官方说法是

root@kapelner-gradesly:~# cat /var/log/nginx/kapelner_error.log
...
2023/07/18 12:29:22 [error] 444642#444642: *16 "/root/deploy/gradeportal/current/public/kapelner/index.html" is not found (2: No such file or directory), client: 72.226.69.230, server: kapelner.com, request: "GET / HTTP/1.1", host: "kapelner.com"

型
我的理解是它和上游的美洲狮没有联系。
有人知道我哪里做错了吗？
编辑：
我修改了我的配置文件：

root@kapelner-gradesly:~# cat /etc/nginx/conf.d/kapelner.conf
server {
  listen 80;
  server_name kapelner.com *.kapelner.com;
  return 301 https://$host$request_uri;
}

server {
       listen   443 ssl;

       #location @app {
       #   proxy_pass https://app;
       #   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       #   proxy_set_header Host $http_host;
       #   proxy_redirect off;
       # }

        root /root/deploy/gradeportal/current/public;
        server_name kapelner.com *.kapelner.com;
        #index index.htm index.html;
        try_files $uri @app;

        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot

                rewrite ^(.*)$ /kapelner$1 break;
        }

}

重启nginx然后我仍然得到相同的错误消息：

root@kapelner-gradesly:~# cat /var/log/nginx/kapelner_error.log
...
2023/07/18 13:40:32 [error] 445188#445188: *2 "/root/deploy/gradeportal/current/public/kapelner/index.html" is not found (2: No such file or directory), client: 72.226.69.230, server: kapelner.com, request: "GET / HTTP/1.1", host: "kapelner.com"

型
也许在其他包含的conf文件中还有其他内容。这是

root@kapelner-gradesly:~# cat /etc/letsencrypt/options-ssl-nginx.conf
ssl_session_cache shared:le_nginx_SSL:10m;
ssl_session_timeout 1440m;
ssl_session_tickets off;

ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers off;

ssl_ciphers "ECDHE-<cipher continues, no need to show it>-SHA384";

型
conf.d文件夹中没有其他内容：

root@kapelner-gradesly:~# cd /etc/nginx/conf.d
root@kapelner-gradesly:/etc/nginx/conf.d# ls -lh
total 4.0K
-rw-r--r-- 1 root root 1.1K Jul 18 13:39 kapelner.conf

型
sites-enabled目录中没有任何内容：

root@kapelner-gradesly:/etc/nginx# cd sites-enabled/
root@kapelner-gradesly:/etc/nginx/sites-enabled# ls -lh
total 0

型
太奇怪了。还有什么我能试试的吗？

您在http部分中命名了上游app，但server_name与上游名称不匹配。
尝试以下操作

server {
  listen 80;
  server_name app;
  return 301 https://$host$request_uri;
}

希望能成功。下面是一个参考配置how to start puma with unix socket。
