在同一服务器上部署express后端和react前端时遇到困难

Question

我一直试图将我的第一个完整的MERN堆栈部署到实际的服务器上，而不是Heroku和Netlify,

null

2.安装nodejs、pm2、Nginx

我使用ssh复制react build文件夹中的所有文件：

asset-manifest.json  favicon.ico  index.html  logo192.png  logo512.png  manifest.json  robots.txt  static```

我设置了Nginx以将该文件夹服务为端口80中的IP的默认请求

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

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

        server_name your_domain www.your_domain;

        location / {
                try_files $uri $uri/ =404;
        }
}```

```
ubuntu@first:~/server$ ls
config  node_modules  package.json  package-lock.json  README.md  src

```

ubuntu@first:~/server$ pm2 show 0

我一直在做这方面的工作，并试图学习一切一个星期，现在只是为了学习部署，任何帮助都将不胜感激

Answer 1

服务器应用程序正在运行吗？您是否看到端口打开(netstat-一个grep 5000)？webserver和server应用程序位于同一主机上，因此您应该能够通过本地主机访问：5000

我确实喜欢他们联系到的Taleodor的答案。如果需要，使事情变得更加简单和便携。
