run

start nginx

# run nginx test
sudo nginx -t

# for systemd based
sudo systemctl start nginx

start uwsgi

uwsgi --ini ~/app1/uwsgi.ini

当然也可以做成 systemd unit file, 不赘述

result

bare ip address ip/start

attention

在测试过程中遇到了一个麻烦, uwsgi 老是出现奇怪的错误,检查一番后发现是由于采用了 pyenv 下 python 环境所致,重新采用系统的 python 环境(或通过 virtualenv 构建的环境)即可正常使用.
