ubuntu18でFlaskのアプリ外部公開

まず

sudo apt install -y nginx ufw
pip3 install flask uwsgi
sudo ufw allow 80
sudo ufw allo 443

つぎ

cd /etc/nginx/sites-available/
sudo vim hogehoge.com.conf

server {
    listen 80;
    server_name hogehoge.com;
    location / {
        include uwsgi_params;
        uwsgi_pass unix:///tmp/uwsgi.sock;
    }
}

cd ../sites-enabled
sudo ln -s ../sites-available/hogehoge.com.comf

そして

cd ~
mkdir flask
cd flask
vim app.py

from flask import *
app = Flask(__name__)
@app.route("/")
def hello():
    return "neko_ni_naritai"

if __name__ == "__main__":
    app.run(debug=True)

とりあえず

python3 app.py

最終確認

vim myapp.ini

[uwsgi]
module = app
callable = app
master = true
processes = 1
socket = /tmp/uwsgi.sock
chmod-socket = 666
vacuum = true
die-on-term = true
#venv = /home/syaro/.pyenv/versions/3.7.0/ #venv使う人は使おうね
logto = log_%n.log
user = syaro

これで一応うごく

$ uwsgi --ini=myapp.ini

これでscreenとかsupervisorとか使うのもあり /usr/bin/pythonが2.xの人は、

cd /usr/bin/
sudo unlink python
sudo ln -s python3 python

にしたほうがうまくうごく

これをsystemdに登録 sudo vim /etc/systemd/system/uwsgi.service

[Unit]
Description = uwsgi

[Service]
Restart = always
WorkingDirectory=/home/syaro/flask
ExecStart = uwsgi --ini /home/syaro/flask/myapp.ini
ExecReload = /bin/kill -s HUP ${MAINPID}
KillSignal = kill -QUIT
User = syaro
Group = syaro

[Install]
WantedBy = multi-user.target

sudo systemctl restart uwsgi
sudo service nginx restart
