react-router 无法在 ubuntu 18.04 上与 nginx 和 pm2 协同工作

Question

我已经使用 react 构建了一个应用程序，并使用 pm2 和 nginx 将其部署在 ubuntu 上。我使用 react-router 进行路由。这是我的项目文件配置的样子，我创建了一个指向默认文件的符号链接。使用下面的命令我检索了它。出于安全原因，我在此处的配置文件中用 mydomain.domain 替换了 myactual 域和项目文件夹。

sudo nano /etc/nginx/sites-available/mydomain.domain

    server {

        root /var/www/mydomain.domain/html;
        index index.html index.htm index.nginx-debian.html;

        server_name mydomain.domain www.mydomain.domain;

        location / {
                proxy_pass http://localhost:8080;
                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;
                # try_files $uri $uri/ =404;
        }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/mydomain.domain/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/mydomain.domain/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = mydomain.domain) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

        listen 80;
        listen [::]:80;

        server_name mydomain.domain www.mydomain.domain;
    return 404; # managed by Certbot
}

以下是我的默认文件配置：

sudo nano /etc/nginx/sites-available/default

##
# You should look at the following URL's in order to grasp a solid understanding

#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.

# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.

        root /var/www/html;

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

        server_name _;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
 #try_files $uri $uri/ /index.html;
                try_files $uri $uri/ =404;
        }

        # pass PHP scripts to FastCGI server
        #
        #location ~ \.php$ {
        #       include snippets/fastcgi-php.conf;
        #
        #       # With php-fpm (or other unix sockets):
        #       fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        #       # With php-cgi (or other tcp sockets):
        #       fastcgi_pass 127.0.0.1:9000;
        #}

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


# Virtual Host configuration for example.com
#
# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
#       listen 80;
#       listen [::]:80;
#
#
#       server_name example.com;
#
#       root /var/www/example.com;
#       index index.html;
#
#       location / {
#               try_files $uri $uri/ =404;
#       }
#}

通过搜索该问题，我得到了以下解决方案：

   location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri /index.html;
    }

但即使通过在默认文件或甚至我的项目配置文件中对其进行更改，问题仍然没有解决。

我也尝试了下面的解决方案，但对我来说也没有用，这就是我重新发布上述问题的原因。

location / {
                try_files $uri $uri/ /index.html;
        }
