Re: Advice: django deploy vps error 502

Hello,

502 usually means the backend isn't running. After you finish the test, has the backend stopped running? Does it continue to throw 502s? If that is the case, I'm wildly guessing that processes might be growing and growing in memory and being eventually killed, but I don't really know. Do you have DEBUG = False? Does uwsgi write something in its log? Does the system write something in the syslog?

Regards,

Antonis

Hi, all

16GB RAM

8 core processor

160 GB SSD

6TB Transfer

ok, i am using, uwsgi(2.0.14), nginx(1.10), mysql(5.6 )and ubuntu 16.04 LTS

this site working well when is visited or hits 1k even 6k, but when visited 10k or 12k

raiser error 502,

When I do a test of ab like these command line

ab -k -c 350 -n 20000 mydomain.com/

again raiser the error 502 in almost pages

these are configs all, wsgi, nginx

---- uwsgi script in /etc/uwsgi/app-availabre/website.ini -----

http://pastebin.com/vQW47WGb

---- nginx conf in /etc/nginx/nginx.conf  ------

http://pastebin.com/5BsWWaps

----- nginx vhost for my website mydpmain --------

http://pastebin.com/bMPvmrwR

How can I do so that the site does not throw the error?

Are the settings correct?

How can i know the layer support the vps?

In nginx how to stop the ab test, if many people do the test the web site throws the error 502 ngixn

I would appreciate it if someone gave me an idea or advice to configure better when there is high traffic or are doing ab test or another benchmarking test

cheers
