可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I'm using Flask/Gunicorn to run a web application and have a question about the lifecycle management. I have more experience in the Java world with servlets. I'm creating a restful interface to a service. The service is always running on the server and communicates and controls with a set of sub-servers. In Java, my service would be created and initialized (e.g. the setup traditionally found in main() ) through listeners and servlet initialization methods. Where would the equivalent setup and configuration be in Flask? I'm thinking of tasks

gunicorn + nginx: Server via socket or proxy?

问题 I've seen two strategies for hosting a django application with gunicorn and nginx. One strategy is to run gunicorn on a network port. For example (from http://goodcode.io/blog/django-nginx-gunicorn/): location / { proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 10; proxy_read_timeout 10; proxy_pass http://localhost:8000/; } Another strategy is to bind gunicorn to a

What exactly is a pre-fork web server model?

问题 I want to know what exactly it means when a web server describes itself as a pre-fork web server. I have a few examples such as unicorn for ruby and gunicorn for python. More specifically, these are the questions: What problem does this model solve? What happens when a pre-fork web server is initially started? How does it handle request? Also, a more specific question for unicorn/gunicorn: Let's say that I have a webapp that I want to run with (g)unicorn. On initialization, the webapp will do

Why gunicorn does not load my css files that are into the static folder of my project? Guinicorn_start script: https://dpaste.de/TAc4 Gunicorn output: https://dpaste.de/C6YX 回答1: Gunicorn will only serve the dynamic content, i.e. the Django files. So you need to setup a proxy server such as nginx to handle the static content (your CSS files)

Gunicorn with Flask using wrong Python

痴心易碎 提交于 2019-12-03 01:57:01
I'm trying to bootstrap a Flask app on a Gunicorn server. By putting the two tools' docs together, plus searching around on SO, this is what I have so far... but it's not quite working. app.py : from flask import Flask, render_template from flask.ext.sqlalchemy import SQLAlchemy from werkzeug.contrib.fixers import ProxyFix app = Flask(__name__) app.wsgi_app = ProxyFix(app.wsgi_app) db = SQLAlchemy(app) @app.route('/') def index(): return render_template('index.html') what I ran : From the same directory as app.py, gunicorn app:app Even starting this small, I've missed something.

What benefit is added by using Gunicorn + Nginx + Flask? [duplicate]

馋奶兔 提交于 2019-12-03 01:53:58
问题 This question already has answers here : Are a WSGI server and HTTP server required to serve a Flask app? (2 answers) Closed 9 months ago . I see people are running setups like Nginx + Gunicorn + Flask. Can someone explain what is the benefit of having Gunicorn in front of Flask? Why not just run Flask alone? Doesn't it consume more resources having Gunicorn + Flask running? Is Gunicorn able to reboot the Flask instance when it fails to respond? What's also the purpose of having nginx on top

在python的虚拟环境venv中使用gunicorn

昨天遇到的问题,一个服务器上有好几个虚拟机环境。 我active进一个虚拟环境,安装了新的三方库之后, 使用gunicorn启动django服务, 但还是死活提示没有安装这个三方库。 一开始没有找到原因,后来,在启动的进程里发布了痕迹, 原来,这个gunicorn启动时的python为另一个venv里的python。 soga~~改过来罗。。。 /venv/bin/gunicorn #!/docker/venv/bin/python3.6 # -*- coding: utf-8 -*- import re import sys from gunicorn.app.wsgiapp import run if __name__ == '__main__': sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) sys.exit(run()) 注意红色部门的python要和自己的虚拟环境路径一致!!!!! 来源: https://www.cnblogs.com/aguncn/p/11769431.html
