我是新手,并且只使用nginx来提供静态文件。我现在已经安装了烧瓶和手枪。如果我运行gunicorn -b 127.0.0.2:8000 hello:app
,然后从服务器中获取它,它运行良好。但是,如果我尝试从浏览器访问它,它会返回404错误(我在托管wordpress站点的服务器上运行此错误,该站点位于root用户)。
烧瓶应用程序:
from flask import Flask
from werkzeug.contrib.fixers import ProxyFix
app = Flask(__name__)
@app.route('/')
def hello():
return "Hello world!"
app.wsgi_app = ProxyFix(app.wsgi_app)
if __name__ == '__main__':
app.run()
我的nginx配置的相关部分:
location /flask {
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_\
for;
proxy_pass http://127.0.0.2:8000;
proxy_redirect off;
}
我希望这是所有相关信息。如果没有,请告诉我。谢谢!

这就是我在Nginx中提供烧瓶应用的方式:
使用套接字运行gunicorn daemonized:
sudo gunicorn app:app --bind unix:/tmp/gunicorn_flask.sock -w 4 -D
相关的nginx配置:
upstream flask_server {
# swap the commented lines below to switch between socket and port
server unix:/tmp/gunicorn_flask.sock fail_timeout=0;
#server 127.0.0.1:5000 fail_timeout=0;
}
server {
listen 80;
server_name www.example.com;
return 301 $scheme://example.com$request_uri;
}
server {
listen 80;
client_max_body_size 4G;
server_name example.com;
keepalive_timeout 5;
# path for static files
location /static {
alias /path/to/static;
autoindex on;
expires max;
}
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
if (!-f $request_filename) {
proxy_pass http://flask_server;
break;
}
}
}
}
