How to Programming with Uwsgi

I think you are running uwsgi in http mode --http 0.0.0.0:8002 but you have configured nginx as wsgi proxy change your uwsgi script as: uwsgi --socket :8002 --module wsgi --harakiri 5 Note that if you are running nginx and uwsgi on the same machine is better to use unix sockets...

uwsgi socket file not created

django,docker,uwsgi,supervisord

Changing owner to www-data on /var/www/django/ made it work.

Application served by uWSGI with Supervisord from Docker

How are you starting the docker container? I don't see any CMD or ENTRYPOINT script, so I'm unclear as to how anything is getting started. In general, I would advice avoiding things like supervisord unless absolutely necessary, just start uWSGI in the foreground from a CMD line. Try adding the...

Running rbtimer from emperor

python,django,flask,wsgi,uwsgi

You need a process (a worker or a mule) to run the signal handler. Spawn a worker (adding a socket directive) or a mule (adding mule = true). In the case of a mule you need to add target=mule to the @rbtimer decorator)

uWSGI env and PYTHON_EGG_CACHE configuration options

python,multithreading,flask,uwsgi

evn option exports an environment variables to the UWSGI web server process. The option can be specified manyt times to export multiple varibles. The values can be read from os.environ dict in Python. PYTHON_EGG_CACHE is not uWSGI specific and it is answered here: What is the Python egg cache (PYTHON_EGG_CACHE)?...

Why is uWSGI incapable of locating the functools module for Flask?

python,nginx,flask,debian,uwsgi

I re-imaged the system to Arch Linux to remove as many variables as possible, downloaded and built uWSGI from source, got around to installing a specific Python version and realized Python 3.2 isn't supported by Flask. When I installed it on Debian, it installed with Python 3.2 and Arch's package...

Flask: Background thread sees a non-empty queue as empty

From the Things to Know documenation page: uWSGI tries to (ab)use the Copy On Write semantics of the fork() call whenever possible. By default it will fork after having loaded your applications to share as much of their memory as possible. If this behavior is undesirable for some reason, use...

Invalid transaction persisting across requests

python,flask,sqlalchemy,uwsgi,flask-sqlalchemy

Edit 2015-04-13: Mystery solved! TL;DR: Be absolutely sure your teardown functions succeed, by using the teardown-wrapping recipe in the 2014-12-11 edit! Started a new job also using Flask, and this issue popped up again, before I'd put in place the teardown-wrapping recipe. So I revisited this issue and finally figured...

Deployment of Python API

django,api,nginx,deployment,uwsgi

Security, what this is ultimately about, is and always has been a very complicated matter. The open internet is one of the most dangerous places. No matter how small and insignificant your server seems to be, people will find it and try to break it. If a web server is...

How can I avoid uwsgi_modifier1 30 and keep WSGI my application location-independent?

nginx,uwsgi,cherrypy

My answer is really about simplifying things, because the following and the amount of configuration you have indicates one thing -- overkill. CherryPy ⇐ WSGI ⇒ uWSGI ⇐ uwsgi ⇒ Nginx ⇐ HTTP ⇒ Client CherryPy has production ready server that natively speaks HTTP. No intermediary protocol, namely WSGI, is...

uWSGI unique timer python decorator

uwsgi,python-decorators

Use the uWSGI locking api: from uwsgidecorators import * @timer(600) #every 10 minutes def myfunction(signum): if uwsgi.is_locked(): return uwsgi.lock() .... uwsgi.unlock() http://uwsgi-docs.readthedocs.org/en/latest/Locks.html...

Populate cache before app is fully available

uwsgi

A prerequisite is that uWSGI actually has caching enabled, something like: [uwsgi] cache2 = name=mycache,items=100 There are many options for startup hooks. Take a look at this page in the uWSGI doc. You can choose at what point in the uWSGI startup sequence you want to hook up (as-root, as-user,...

uwsgi --stats show different port number for socket

uwsgi

When you start uWSGI with --http you are starting a http proxy that forward requests to the real instance. The stats you get are from the real instance, that is bound to a random port (the one you see in stats) where the http router/proxy forward requests. You can have...

How to create one uwsgi log file per day?

uWSGI by itself can only "split by size", with the --log-maxsize option. Time-based approaches are using classic logrotate or apache rotatelogs (http://httpd.apache.org/docs/2.2/programs/rotatelogs.html) that you can combine with uWSGI logpipe plugin. Finally you can have an nginx like behaviour triggering a reload at midnight of the uWSGI instance (you can even...

Fixing broken pipe error in uWSGI with Python

python,rest,timeout,wsgi,uwsgi

it depends on your frontend server. For example nginx has the uwsgi_read_timeout parameter. (generally set to 60 seconds). The uWSGI http router as the --http-timeout default to 60 seconds and so on. As you are talking about a rest api i am quite doubtful it requires more than 60 seconds...

i can access flask app directly the port 8080 though then through nginx reverse proxy I get an error

Unable to link Flask module to nginx through uwsgi

linux,deployment,nginx,web-deployment,uwsgi

You're application function does not call your flask app, which is why every route returns "Hello World", 200. I'm pretty sure you have two easy options. The first is to drop the application function and replace it with application = app. The second would be to change the uwsgi line...

wsgi nginx error: permission denied while connecting to upstream

uWSGI + Docker: pyuwsgi: executable file not found in $PATH

python,django,docker,uwsgi

Turns out I'm pretty dumb. [docker] section of uwsgi.ini needs to have ini = :base, not init = :base. The base section wasn't being parsed, so the wsgi module was never getting set. Always proofread your work, friends....

Is it necessary to run miltiple uWSGI web-sites with different users?

It is a general security rule. Immagine one of your app being compromised, if it runs with the same permissions of the others it will be potentially able to damage them as well.

Django Internal Server Error instead of 404

How integrate a websocket between tornado and uwsgi?

python,websocket,tornado,uwsgi

The uWSGI tornado loop engine is no more than a proof of concept, you could try to use it but native uWSGI websockets support or having nginx routing requests to both uWSGI and tornado are better (and more solid) choices for sure.

uWSGI process doesn't inherit permissions associated with group its uid belongs to

Following up on dgel's suggestion to learn about Unix permissioning: when you run processes in Unix, there are basically 3 ways you can wind up being "green lit" permissions-wise by the OS. The user calling the command can be user-permissioned for the disk operation (green-lit because of effective user id)...

How to reload a python library in a flask, nginx, uwsgi stack?

python,logging,flask,multiprocessing,uwsgi

The Python process started by uWSGI only interprets the source once at startup, any code changes after that will not affect the in-memory process. You should probably just manually restart the uWSGI process when this happens. Alternatively you can tell uWSGI to auto-reload if files or directories change: http://uwsgi-docs.readthedocs.org/en/latest/Options.html#touch-reload.

Deploying Flask application with uwsgi and nginx

python,deployment,nginx,flask,uwsgi

It doesn't matter how complex your application is. You tell uWSGI where the entry is, the rest is processed normally with Python imports. In your case the entry is module = %(app) and callable = app. So uWSGI will load the module and send requests to the callable which is...

sqlite3 cannot open database file, running Centos, flask uwsgi nginx

Flask sub.domain.com overrides session on domain.com

session,nginx,flask,subdomain,uwsgi

By mistake I thought it has nothing to do with my reverse proxy or uwsgi. Actually it was problem with reverse proxy and I could solve my problem by adding following rules to nginx: proxy_cookie_domain media.$host $host; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect...

Atomic log file rotation with Flask and RotatingFileHandler

Note that writing to a single log file from multiple processes isn't supported, because there is no cross-platform synchronisation mechanism that can be used. See this cookbook entry for a suggested approach which might work for you.

Django, uwsgi and nginx - Internal Server Error

python,django,nginx,uwsgi

You are probably lacking a chdir line in your uwsgi_conf.ini. Or, probably, you have a chdir line, but it is wrong. This is confirmed by your traceback: File "./wsgi.py", line 16, in <module> Here you should see ./api/wsgi.py, not ./wsgi.py. Clearly, the working directory of uWSGI is the api/ directory,...

nginx permission denied while reading upstream - even when run as root

Okay! So the problem was, I think, related to this bug. It seems that even though apparmor wasn't configured to prevent access to sockets inside the containers it was actually doing something to prevent reading from them (though not creation...) so turning off apparmor for the container (following these instructions)...

uwsgi cannot work on a cloud server

django,git,service,production-environment,uwsgi

Check the firewall rules. Arbitrary ports like 8001 tend to be disabled from outside access out of the box. Should work just fine from the command line on the server, e.g. $ curl localhost:8001.

The problem happens because your process fails to allocate a chunk of memory. When I first look at your code, the first thing that drew my attention was that you are loading entire content of file into memory and read them all at once at each iteration. zip.writestr("{0} - {1}.{2}".format(num,...

Starting uWSGI service fails silently

Thanks to nmgeeks comment, I started looking at other places where uWSGI is configured. While trying to move everything our own app related under /srv I deleted /run/uwsgi directory, where uWSGI is trying to create a PID file. You can find the reference at /usr/share/uwsgi/conf/default.ini. Too bad uWSGI doesn't produce...

nginx uwsgi websockets 502 Bad Gateway upstream prematurely closed connection while reading response header from upstream

uwsgi broken pipe - django, nginx

python,django,nginx,tastypie,uwsgi

you can safely ignore them, they are triggered by the client (or nginx) disconnecting in the middle of the request. As the response times are really low, it is very probably a client disconnection. Btw, post your nginx and uWSGI configuration for being sure.
