[英]Flask + Gunicorn + Nginx, 404 error using proxy_pass from non-root location block
I would like to take some user input, run a few lines of Python, and display the results on the web.我想获取一些用户输入,运行几行 Python,然后在 Web 上显示结果。
I have a domain pointed to a server on DigitalOcean, and am following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-18-04我有一个域指向 DigitalOcean 上的服务器,并且正在学习本教程: https : //www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on -ubuntu-18-04
I've been able to get through the tutorial and it does work, however I'd of course like for my site not to be completely overridden by the phrase "Hello there!".我已经能够完成教程并且它确实有效,但是我当然希望我的网站不会被“你好!”这句话完全覆盖。 I would like to display the results at a non-root location such as https://example.com/myproject/
.我想在非 root 位置显示结果,例如https://example.com/myproject/
。
The domain I have has already been secured using Let's Encrypt & CertBot.我已经使用 Let's Encrypt & CertBot 保护了我的域。
I am using a single nginx config file called default - the rest of the tutorial I followed exactly.我正在使用一个名为 default 的 nginx 配置文件 - 我完全遵循本教程的其余部分。 The problem seems to be in the proxy_pass directive.问题似乎出在 proxy_pass 指令中。 When I move it to the / location block, it works and my index page is overridden with "Hello there!".当我将它移动到 / location 块时,它可以工作并且我的索引页面被“Hello there!”覆盖。 When I move proxy_params and proxy_pass to a /myproject/ location block, I get a 404 error.当我将 proxy_params 和 proxy_pass 移动到 /myproject/ 位置块时,我收到 404 错误。 I've tried a handful of things and tried to understand location blocks better, but to no avail.我尝试了一些东西并试图更好地理解位置块,但无济于事。
Here is the Nginx config file:这是 Nginx 配置文件:
# Default server configuration
#
server {
root /var/www/html;
# Add index.php to the list if you are using PHP
index index.html index.htm index.php;
server_name example.com www.example.com;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
location /myproject/ {
include proxy_params;
proxy_pass http://unix:/home/jackson/myproject/myproject.sock;
}
# pass the PHP scripts to FastCGI server
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
location ~ /\.ht {
deny all;
}
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
Any help would be greatly appreciated.任何帮助将不胜感激。 Thank you!谢谢!
I needed to change the @app.route decorator in the .py file to the correct directly, and I think crucially specify the GET
and POST
methods.我需要将 .py 文件中的 @app.route 装饰器直接更改为正确的,我认为至关重要的是指定GET
和POST
方法。
from flask import Flask
app = Flask(__name__)
@app.route("/myproject/", methods=['GET','POST'])
def hello():
return "<h1 style='color:blue'>Hello There!</h1>"
if __name__ == "__main__":
app.run(host='0.0.0.0')
