error: swift cache could not be found in env!

Hi,

Could you share proxy-server conf and memcached.conf?

Hi,
memcached.conf is https://drive.google.com/file/d/0B4uP_0R-AEKjT3lBdXZnVkFMOGs/edit?usp=sharing
and proxy-server.conf is https://drive.google.com/file/d/0B4uP_0R-AEKjVzEyUzh0LTNjbVk/edit?usp=sharing

where can i find my proxy server ip address? should i set it with bind_ip?
Thanks

After doing what you said and trying to start proxy server with the command:
swift-proxy-server /etc/swift/proxy-server.conf it throws an exception:
Could not bind to 0.0.0.0:8080 aster trying for 30 seconds.

proxy server ip that your virtual machine ip located on the proxy server.

After following the instructions you gave me the same error still pops up in syslog and i get 503 server internal error. Any more ideas?
Thanks

Thanks Mehmet Hacısalihoğlu, that solved my question.

Can you please post the final config you used. I am also stuck on this problem and I have tried everything I can think of to get the memcached server and proxy-server to play nice together.

Thanks...

Hi,
Well this problem still happens on my syslog but now i dont have any problems.
The thing that was going wrong with mine server is that when i used startmain to start all the servers the output i got was that all started but they didnt.
I started them manually.
I used:
service swift-proxy restart (or start)
service swift-account restart
service swift-container restart
service swift-object restart

The memcached error is still there.. nothing worked that could remove it.

Ok thank you...

I am able to get tempauth to work, but I am not sure if that means that memcached is working because I get these two errors in my proxy.error file all the time:

Jan 9 16:45:13 willswift proxy-server: STDOUT: ERROR:root:ERROR: swift.cache could not be found in env! (txn: txc75a7ce83d454b479b8c3-0052cf1869)
Jan 9 16:45:13 willswift proxy-server: Warning: Cannot ratelimit without a memcached client (txn: txc75a7ce83d454b479b8c3-0052cf1869)

I also have another error, but it might be associated with the auth middleware I wrote. Unfortunately I am not able to see the real error because of the MAXLINES truncation of syslog. :(

memcache_client.set('mauth_creds/%s/%s' % (auth_user, auth_key), (expires, identity), time=env.get('HTTP_X_AUTH_TTL', self.cache_timeout))#012UnboundLocalError: lo

I will see what I can figure out... Thanks for posting back...

I can't help on these cause i am not at the dev team hehe :)
No problems, i hope you can figure it out shortly.

Also, don't forget to make sure "cache" occurs in your pipeline *before* tempauth, like so:

pipeline = catch_errors proxy-logging cache ...others... tempauth proxy-logging proxy-server

Yes, I have cache in the pipeline before the auth middlewares.

I have fixed an issue with my auth middleware, so my 'UnboundLocalError' has been fixed.

I am still getting the following two errors in the proxy.error log, but everything is working:
Jan 10 15:17:34 willswift proxy-server: STDOUT: ERROR:root:ERROR: swift.cache could not be found in env! (txn: tx2d94b78541344672bab6d-0052d0555e)
Jan 10 15:17:34 willswift proxy-server: Warning: Cannot ratelimit without a memcached client (txn: tx2d94b78541344672bab6d-0052d0555e)

I have verified that memcache is actually working because my auth system in successfully saving and pulling identities from the 'memcache_client' (as defined here: "memcache_client = cache_from_env(env)"). So everything is working, but the errors are still being reported.

I am on Swift 1.11. A co-worker has Swift 1.13 installed and running in dev and he is not seeing these errors, so maybe this issue has been found and solved already.

Thanks for following up. This is not blocking me...

Those warnings are coming from the ratelimit middleware; it also has to come after cache in the pipeline. Ratelimit won't break the proxy in this case, but it also won't do any limiting.

Nice catch. I moved 'ratelimit' after cache in the pipeline and I no longer have any errors.

Thank you for following up to clarify that...
