我在使用nginx和tmux的单个EC2服务器上在2个不同的子域上运行2个不同的streamlit应用程序时遇到了困难。

第一阶段：我第一次尝试只运行1个应用程序成功，我的nginx配置如下：

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

        root /var/www/html;

        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location / {
                proxy_pass http://localhost:8501;
                proxy_http_version 1.1;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $host;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 86400;
        } 
}

字符串

第二阶段：然而，当我尝试运行2个不同的streamlit应用程序时。它不起作用。我的nginx配置文件如下：

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

        root /var/www/html;

        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location /app {
                proxy_pass http://localhost:8501;
                proxy_http_version 1.1;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $host;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 86400;
        }
}

        location /upload {
                proxy_pass http://localhost:8502;
                proxy_http_version 1.1;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $host;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 86400;
        }
}

当我深入浏览器控制台时，以下2个文件被报告为不可用。

1. 404（Not Found）页面没有找到
2. 404（Not Found）404（Not Found）
   这两个文件实际上是为streamlit安装的site-packages。

第三阶段：我试图通过将根目录传递到相应的位置来修复上述错误。以及在位置URL后添加斜杠。更新配置文件如下：

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

        root /var/www/html;

        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location /app/ {
                root /home/ubuntu/.local/lib/python3.8/site-packages/streamlit;
                proxy_pass http://localhost:8501;
                proxy_http_version 1.1;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $host;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 86400;
        }

        location /upload/ {
                root /home/ubuntu/.local/lib/python3.8/site-packages/streamlit;
                proxy_pass http://localhost:8502;
                proxy_http_version 1.1;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $host;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 86400;
        }
}

不幸的是，我仍然面临问题。我想到了一个稍微不同的例子，如下：

1. 404 Not Found（未找到）
2. 404 Not Found（未找到）
