我有一个尝试使用 Gunicorn 和 nginx 部署的 Flask 应用程序。然而,虽然它在本地运行良好,但当我在远程服务器上使用 Gunicorn 运行时,它会引发 TemplateNotFound 错误。
我什至不知道如何开始调试它,更不用说它为什么会失败......如果不是后者,我会喜欢前者的帮助。我认为这可能是权限问题,所以将模板文件夹更改为 777 ......不走运。这是所有相关的细节:
安装脚本
从一个裸 Ubuntu 10.04 安装开始,我运行它来设置服务器并拉入我的代码:https ://github.com/total-impact/total-impact-deploy/blob/master/deploy.sh 。然后我把这个 nginx 配置文件放在 /etc/nginx/sites-available/total-impact:
server {
location / {
proxy_pass http://127.0.0.1:8000;
}
}
最后,我浏览应用程序目录并运行gunicorn web:app
,然后点击服务器的 IP 地址。这会在浏览器中生成 500,并在命令行上输出:
