Login issue with a nginx proxy - galaxy-dev

16 Oct 2014


      Hello galaxians,
I'm currently trying to set up a production galaxy and make it available to
the public but I face a weird issue, probably because of my nginx proxy
configuration.
Galaxy is on a kvm virtual machine running on a host using nginx as proxy.
to make it a bit clearer:
172.30.24.35 (client) ---> http://172.30.24.63/machine1 (Host & nginx
proxy) --- > http://192.168.122.254:8080/ (virtual machine)
I can connect to galaxy but when logging in, the virtual machine redirects
me on 192.168.122.254:8080, which is unreachable from the 172.30.24.0
network. If I log in from the Host, it's all fine.
in the universe_wsgi.ini, i've set:
# Define the proxy-prefix filter.
[filter:proxy-prefix]
use = egg:PasteDeploy#prefix
prefix = /machine1
...
# [filter:proxy-prefix] section above.
filter-with = proxy-prefix
as described in the documentation.
My virtual machine nginx conf file:

worker_processes  2;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
