Internal Test
uwsgi --http='192.168.123.123:9980' --chmod-socket='666' --master --enable-threads --mount='/=hello:server' curl -i 192.168.123.123:9980
File Socket for Nginx
uwsgi --socket='/tmp/uwsgi.sock' --chmod-socket='666' --master --enable-threads --mount='/=hello:server'
No python application found のエラーが出る場合は mount の引数で指定したモジュールが問題なく実行できるか確認
sudo vi /etc/nginx/conf.d/app.conf
======================================
server {
listen 8080;
location / {
include uwsgi_params;
uwsgi_pass unix:/tmp/uwsgi.sock;
}
}
======================================
sudo systemctl restart nginx
