ubuntu18.04 + Flask + uWSGI + Nginxで超簡単Webサーバー
1. 環境作成
$ sudo apt install python3-pip python3-venv python3-dev
$ mkdir ~/myapp; cd ~/myapp
$ python3 -m venv env
$ source env/bin/activate
(env) $ pip install uwsgi flask2. ファイル作成
~/myapp/server.py
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "<h1 style='color:blue'>Hello There!</h1>"
if __name__ == "__main__":
app.run(host='0.0.0.0')
~/myapp/wsgi.py
from server import app
if __name__ == "__main__":
app.run()
~/myapp/server.ini
[uwsgi]
module = wsgi:app
master = true
processes = 1
socket = server.sock
chmod-socket = 666
vacuum = true
die-on-term = true
touch-reload = server.py/etc/systemd/system/myapp.service
[Unit]
Description=uWSGI instance to serve myapp
After=network.target
[Service]
User=<user>
Group=www-data
WorkingDirectory=/home/<user>/myapp
Environment="PATH=/home/<user>/myapp/env/bin"
ExecStart=/home/<user>/myapp/env/bin/uwsgi --ini server.ini
[Install]
WantedBy=multi-user.target
3. サービス起動
$ sudo systemctl start myapp
$ sudo systemctl enable myapp # 自動起動
$ sudo systemctl status myapp # 確認4. プロキシ設定
/etc/nginx/sites-available/myapp
server {
listen 80;
server_name <domain> www.<domain>;
location / {
include uwsgi_params;
uwsgi_pass unix:/home/<user>/myapp/server.sock;
}
}
$ sudo ln -s /etc/nginx/sites-available/myapp /etc/nginx/sites-enabled
$ sudo nginx -t # 確認
$ sudo systemctl restart nginx # 再起動以上、超簡単！
