如何在Nginx上托管的单个域下托管多个Flask应用程序? [英] How to host multiple flask apps under a single domain hosted on nginx?
问题描述
我要实现的目标:
我有一个托管mydomain.com的Nginx Web服务器.当有人在其客户端中键入domain.com时，我希望我的服务器从/var/www/mydomain/提供index.html.当他们键入mydomain.com/flaskapp1时，他们应该看到flaskapp1.当他们键入mydomain.com/flaskapp2时，他们应该看到flaskapp2.
I have an nginx web server hosting mydomain.com. When someone types my domain.com into their client I would like my server to serve index.html from /var/www/mydomain/ When they type mydomain.com/flaskapp1 they should see flaskapp1. When they type mydomain.com/flaskapp2 they should see flaskapp2.
我已经设法通过此处的教程 http://www.markjberger.com/flask-with-virtualenv-uwsgi-nginx/，但是在尝试实现为两个单独的Flask应用程序提供服务时，我遇到了困难.当我尝试在浏览器中使用mydomain.co.uk/flaskapp或mydomain.co.uk/flaskapp2访问任何一个烧瓶应用程序时，都没有看到flask应用程序，而是收到404消息.
I have managed to get one or the other flask apps served using the tutorial here http://www.markjberger.com/flask-with-virtualenv-uwsgi-nginx/ but when trying to implement serving two separate flask apps I run into difficulty. Instead of seeing the flask app I get a 404 message when I try to access either of the flask apps with mydomain.co.uk/flaskapp or mydomain.co.uk/flaskapp2 in a browser.
这是我到目前为止所拥有的:
This is what I have so far:
猫/etc/nginx/sites-available/mydomain.co.uk
server {
listen 80;
server_name www.mydomain.co.uk mydomain.co.uk;
location / {
root /var/www/html/;
index index.html index.htm;
}
location /flaskapp {
include uwsgi_params;
uwsgi_pass unix:/tmp/flaskapp.sock;
}
location /flaskapp2 {
include uwsgi_params;
uwsgi_pass unix:/tmp/flaskapp2.sock;
}
}
以上conf文件已被SIM链接到/etc/nginx/sites-enabled .
The above conf file has been sim linked into /etc/nginx/sites-enabled.
猫/etc/uwsgi/apps-available/flaskapp.ini
[uwsgi]
vhost = true
socket = /tmp/flaskapp.sock
venv = /var/www/flaskapp/venv
chdir = /var/www/flaskapp
module = flaskapp
callable = app
猫/etc/uwsgi/apps-available/flaskapp2.ini
[uwsgi]
vhost = true
socket = /tmp/flaskapp2.sock
venv = /var/www/flaskapp2/venv
chdir = /var/www/flaskapp2
module = flaskapp2
callable = app
两个.ini文件都已符号链接到/etc/uwsgi/apps-enabled 中.UWSGI可以正常重启，并且没有任何问题，并且可以正常运行.flaskapp.sock和flaskapp2.sock都属于www-data
Both .ini files have been symlinked into /etc/uwsgi/apps-enabled. UWSGI restarts fine without any issues and is up and running. Both flaskapp.sock and flaskapp2.sock are owned by www-data
猫/var/www/flaskapp/flaskapp.py
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World from flaskapp1!'
if __name__ == '__main__':
app.run(host='0.0.0.0')
猫/var/www/flaskapp2/flaskapp2.py
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World from flaskapp2!'
if __name__ == '__main__':
app.run(host='0.0.0.0')
猫/var/www/mydomain.co.uk/index.html
<!DOCTYPE html>
<html>
<body>
<h1>mydomain.co.uk</h1>
<p>This is the index page of my domain.co.uk</p>
</body>
</html>
两个虚拟环境均已安装Flask，并将使用开发服务器运行flask应用程序.
Both virtual environments have flask installed and will run the flask apps using the development server.
我希望这是我错过的简单事情.
I hope it's something simple that I've missed.
推荐答案
查看NGINX的uwsgi文档此处.
Looking at the uwsgi documentation for NGINX here.
特别是:
不幸的是，nginx无法将PATH_INFO相应地重写为SCRIPT_NAME.因此，您需要指示uWSGI进行映射所谓的挂载点"中的特定应用，然后重写SCRIPT_NAME和PATH_INFO自动:
Unfortunately nginx is not able to rewrite PATH_INFO accordingly to SCRIPT_NAME. For such reason you need to instruct uWSGI to map specific apps in the so called "mountpoint" and rewrite SCRIPT_NAME and PATH_INFO automatically:
更改我的 flaskapp.ini 和 flaskapp2.ini 文件以包含应用程序的挂载点并打开manage-script-name变量已奏效.
Changing my flaskapp.ini and flaskapp2.ini files to contain the mount points for the apps and turning on the manage-script-name variable has worked.
猫/etc/uwsgi/apps-available/flaskapp.ini
[uwsgi]
vhost = true
socket = /tmp/flaskapp.sock
venv = /var/www/flaskapp/venv
chdir = /var/www/flaskapp
module = flaskapp
callable = app
mount = /flaskapp=flaskapp.py
manage-script-name = true
猫/etc/uwsgi/apps-available/flaskapp2.ini
[uwsgi]
vhost = true
socket = /tmp/flaskapp2.sock
venv = /var/www/flaskapp2/venv
chdir = /var/www/flaskapp2
module = flaskapp2
callable = app
mount = /flaskapp2=flaskapp2.py
manage-script-name = true
现在两个烧瓶应用程序都根据需要通过nginx通过uwsgi运行.
And now both flask apps are running via uwsgi through nginx as required.
