raspbian上的nginx服务器导致错误

Question

因此，我成功地在我的服务器上设置了 Nginx、phpmyadmin/php 和 mysql，该服务器由我的树莓派 4 托管。我试图将 Node.js 作为我的后端，并根据在线的各种教程完成所有操作。当我创建反向代理时，我无法访问 phpmyadmin， 然后我开始尝试配置并开始出现错误。

server {
listen 80 default_server;
listen [::]:80 default_server;

# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# Don't use them in a production server!
#
# include snippets/snakeoil.conf;

root /var/www/html;

# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html index.php;

server_name codenoury.se www.codenoury.se;

location / {
    proxy_pass http://localhost:5000/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
}

# pass PHP scripts to FastCGI server
#
location ~ \.php$ {
    include fastcgi_params;
    # include snippets/fastcgi-php.conf;
    # fastcgi_index index.php
    # fastcgi_param DOCUMENT_ROOT $realpath_root;
    # With php-fpm (or other unix sockets):
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
    deny all;
}

我得到的状态代码

是：

我已经创建了一个主机为 localhost 的用户和一个主机为网站 ip 地址的用户。 phpmyadmin 位于 /var/www/html/ 上的正确目录（根据来源）

。node.js 应用程序在端口 5000 上运行，正如您在配置文件中看到的那样。 我正在使用简单防火墙（ufw）作为防火墙，如果我检查状态，一切似乎都工作正常：

To                         Action      From
--                         ------      ----
Nginx HTTP                 ALLOW       Anywhere
22/tcp                     ALLOW       Anywhere
80/tcp                     ALLOW       Anywhere
443                        ALLOW       Anywhere
Nginx HTTP (v6)            ALLOW       Anywhere (v6)
22/tcp (v6)                ALLOW       Anywhere (v6)
80/tcp (v6)                ALLOW       Anywhere (v6)
443 (v6)                   ALLOW       Anywhere (v6)

所以问题是：

1. 如何使 phpmyadmin 工作，并在使用 node.js 作为服务器和使用反向代理时进行访问在端口 80 上，同时让 Node.js 也能工作。
2. 如何让 nginx 再次工作？

提前致谢。如果您需要任何进一步的信息，请告诉我！
