一、概述

virtualenv，一個虛擬的python環境，一個專屬於專案的python環境。

二、安裝和配置

1.安裝虛擬環境

• 安裝：pip3 install virtualenv
• 建立：virtualenv venv -p /usr/bin/python3.5
• 進入：source venv/bin/activate
• 退出：deactivate

2.配置專案啟動系統服務(虛擬環境)

[Unit]
Description=mc iotapios service
After=network.target

[Service]
User=root
Group=
 
root
WorkingDirectory=/home/workspace/iotapios
Environment="PATH=/home/workspace/iotapios/venv/bin"
ExecStart=/home/workspace/iotapios/venv/bin/gunicorn --bind unix:/run/gunicorn/iot.sock -k gevent iotapios.wsgi

[Install]
WantedBy=multi-user.target

3.配置nginx.conf

upstream iotserver{
    server unix:/run/gunicorn/iot.sock fail_timeout=
 
0;
}

server {
    listen 443 ssl ;
    server_name  www.example.com;
    ssl_certificate /etc/letsencrypt/live/www.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/www.example.com/privkey.pem;
    ssl_session_tickets off;
    
    # auth let's encrypt SSL
	location ^~ /.well-known/acme-challenge/ {
 

        default_type "text/plain";
        root /home/workspace/www;
    }

    location = /.well-known/acme-challenge/ {
        return 404;
    }
    
    # custom....
    location / {
        try_files $uri @auth_success;
    }
}
