Nginx timeouts when uWSGI takes long to process request

Question

I have Nginx + uWSGI for Python Django app.

I have the following in my nginx.conf:

location / {
    include uwsgi_params;
    uwsgi_pass            


        

Answer 1

In addition to the "uwsgi_read_timeout" answer, you should also check that ownership is correct for your nginx uwsgi cache directory. Ownership must be set to the same user as the running nginx process... In my case I had to do this

grep '^user' /etc/nginx/nginx.conf
ls -lah /var/cache/nginx/uwsgi_temp
for f in $( find /var/cache/nginx/uwsgi_temp ); do ls -lah $f; done

Are these files owned by the same user? If not, you could shut down nginx and remove all the cache files, make sure that the proper owner is on /var/cache/nginx/uwsgi_temp and restart. Maybe you could also just do a recursive chown, I didn't test this approach.

# store the user
THEUSER=$(grep '^user' /etc/nginx/nginx.conf | sed 's/.* //; s/;.*//' )

Remove cache and restart approach

/etc/init.d/nginx stop
rm -rf /var/cache/nginx/uwsgi_temp/* 
chown $THEUSER:$THEUSER /var/cache/nginx/uwsgi_temp
/etc/init.d/nginx start

Recursive chown approach

chown -R $THEUSER:$THEGROUP /var/cache/nginx/uwsgi_temp/
# not sure if you have to restart nginx here...
