如何设置文件以在一台服务器上运行多个烧瓶（nginx、gunicorn）应用程序？（指定单独的端口）答案

【问题标题】：How do I setup files to run multiple flask (nginx, gunicorn) applications on one server? (specify separate ports)如何设置文件以在一台服务器上运行多个烧瓶（nginx、gunicorn）应用程序？（指定单独的端口）

【问题描述】：

让每个应用程序自行运行后，您需要在应用程序、nginx 和 gunicorn/service 文件中指定端口。我正在使用 AWS 和 Centos 8 操作系统。

【问题讨论】：

标签： nginx flask gunicorn centos8

【解决方案1】：

下面将显示运行这两个应用程序所需的文件集。在每组文件中，我将有一个文件将在端口 80 上运行，因此无需指定端口，当您想在端口 5000 中运行应用程序时，这会派上用场。第二个文件（App2在每组中）将用于将在端口 3000 上运行的应用程序。端口 3000 是我选择的替代端口，只是因为我看到其他人这样做并且它有效。

VM 上的文件夹结构：

文件设置： /home/ec2-user/environments/App1directory/run.py

from App1 import create_app

app = create_app()

if __name__ == '__main__':
    app.run(debug=False,host="0.0.0.0")

/home/ec2-user/environments/App2directory/run.py

from App2 import create_app

app = create_app()

if __name__ == "__main__":
    app.run(host="0.0.0.0",port=3000)

App1Domain.com.conf

server {
    server_name www.App1domain.com App1domain.com;
    root /home/ec2-user/environments/App1;

    location /static {
    alias /home/ec2-user/environments/App1/App1/static;
    }

    location/{
        proxy_pass http://localhost:8000;
        include /etc/nginx/proxy_params;
        proxy_redirect off;
    }
}
server {
    listen 80;
    listen [::]:80;
    server_name www.App1domain.com App1domain.com;
    root /home/ec2-user/environments/App1;
}

App2Domain.com.conf

server {
    server_name www.App2domain.com App2domain.com;
    root /home/ec2-user/environments/App2;

    location /static {
    alias /home/ec2-user/environments/App2/App2/static;
    }

    location / {
        proxy_pass http://localhost:3000;
        include /etc/nginx/proxy_params;
        proxy_redirect off;
    }
}
server {
    listen 80;
    listen [::]:80;
    server_name www.App2domain.com App2domain.com;
    root /home/ec2-user/environments/App2;
}
