/opt/$mypyenv/bin/python3 -m venv v$mypyenv

django + uwsgi + nginx

sudo apt install nginx npm
sudo npm install -g parcel-bundler
pip3 install django
pip3 install uwsgi
pip3 install pyproj
pip3 install scipy

# 建立django專案(名稱為，remotesensing，路徑為/var/www/cgi-bin)
cd /var/www/cgi-bin
django-admin startproject remotesensing
cd remotesensing
python3 manage.py startapp xbradar


假設我們有一個remotesensing的django project，在PROJHOME=/var/www/cgi-bin/remotesensing 下
設定nginx
#在$PROJHOME/remotesensing/ 下新增 uwsgi_params 檔案
vi $PROJHOME/remotesensing/uwsgi_params
uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;
uwsgi_param  CONTENT_LENGTH     $content_length;

uwsgi_param  REQUEST_URI        $request_uri;

uwsgi_param  REMOTE_ADDR        $remote_addr;
uwsgi_param  REMOTE_PORT        $remote_port;
uwsgi_param  SERVER_PORT        $server_port;
uwsgi_param  SERVER_NAME        $server_name;


#在$PROJHOME/remotesensing/ 下新增 remotesensing_nginx.conf 檔案
vi $PROJHOME/remotesensing/remotesensing_nginx.conf
# the upstream component nginx needs to connect to
upstream django_remotesensing {
     server unix:///var/www/cgi-bin/remotesensing/remotesensing/remotesensing.sock; # 這裏我們預計使用sock檔案，這個路徑必需是uwsgi所指定的路徑(設定檔如下)，另外需注意路徑權限的問題
    #server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name 192.168.10.91; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    # Django media
    location /remotesensing/media  {
        alias /var/www/cgi-bin/remotesensing/media;  # your Django project's media files - amend as required
    }

    location /remotesensing/static {
        alias /var/www/cgi-bin/remotesensing/static; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location /remotesensing {
        uwsgi_pass django_remotesensing;
        include     /var/www/cgi-bin/remotesensing/remotesensing/uwsgi_params; # the uwsgi_params 我們上面新增的uwsgi_params檔案
    }
}

#存檔後將這個檔案製作soft link到 /etc/nginx/sites-enabled 裹
cd /etc/nginx/sites-enabled
sudo ln -s /var/www/cgi-bin/remotesensing/remotesensing/remotesensing_nginx.conf
sudo systemctl restart nginx # 重啟 nginx 服務


設定uwsgi
新增PROJHOME/remotesensing/uwsgi.ini檔
vi /var/www/cgi-bin/remotesensing/remotesensing/uwsgi.ini
[uwsgi]
# 注意，註解要是全新的一行，不要接在設定面，會被當成設定內容，導致錯誤。
chdir        = /var/www/cgi-bin/remotesensing
# Django's wsgi file
#module       = remotesensing.wsgi:application
mount        = /remotesensing=remotesensing.wsgi:application
#按個人習慣，我喜歡把一個PROJ加到URL裏，例如http://my.domain/remotesensing 如果要拿掉，記得上面設定也要改。
manage-script-name = true
#env          = DJANGO_SETTINGS_MODULE=remotesensing.settings.production
env          = DJANGO_SETTINGS_MODULE=remotesensing.settings
# the virtualenv (full path)
home         = /opt/vPy-3.9.5

# process-related settings
# master
master       = true
# maximum number of worker processes
processes    = 2
# the socket (use the full path to be safe
socket       = /var/www/cgi-bin/remotesensing/remotesensing/remotesensing.sock
# 這個是指透過socket連接，不用另外指tcp port，較省資源
#當系統運作時，會在上面的路行建立remotesensing.sock檔，這個路徑必需與nginx.conf一致。另外需注意權限問題，此處是改為666
# ... with appropriate permissions - may be needed
chmod-socket = 666
#uid          = driftertek
#gid          = www-data
# clear environment on exit
vacuum       = true


讓 uwsgi 可以監視某個資料夾(此處設為/etc/uwsgi/vassals)，只要裏面的uwsgi相關的config檔有更勭，就會自動套用
以root的身份建立資料夾
sudo mkdir /etc/uwsgi
sudo mkdir /etc/uwsgi/vassals
把之前建立的uwsgi.ini放建立soft link 到 /etc/uwsgi/vassals 裏
sudo ln -s /var/www/cgi-bin/remotesensing/remotesensing/uwsgi.ini /etc/uwsgi/vassals/


以 root 的身份執行下面指令(注意，如果是用venv，只要以實際的完整路徑去執行uwsgi即可,它會知道相關環境。)
sudo /opt/vPy-3.9.5/bin/uwsgi --emperor /etc/uwsgi/vassals --uid driftertek --gid driftertek
上面這行可以放到rc.local裏去，或是新增成systemctl的一個服務(這裏取名叫djuwsgi)
vi /etc/systemd/system/djuwsgi.service
[Unit]
Description=for django detect uwsgi conf in /etc/uwsgi/vassal

[Service]
Type=simple
ExecStart=/opt/vPy-3.9.5/bin/uwsgi --emperor /etc/uwsgi/vassals --uid driftertek --gid driftertek  --daemonize /var/log/uwsgi/emperor.log

[Install]
WantedBy=multi-user.target

#注意使用者名稱及uwsgi的位置可能不同
#ExecStart=/usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals --uid ihmt --gid ihmt  --daemonize /var/log/uwsgi/emperor.log
#存檔之後
mkdir /var/log/uwsgi 
systemctl start djuwsgi
#設為開機啟動
systemctl enable djuwsgi
systemctl enable nginx # nginx 也順便設一下
systemctl enable postrgresql
