Dear all,

I've been trying to set up a Galaxy instance on my CentOS server but even when I manage to run the simplest configuration correctly I can't seem to get it right on my browser as the connection is refused.

I have changed the host to 0.0.0.0, the port to 8081 and made the appropriate changes in Apache configuration file:

RewriteEngine on
RewriteRule ^/galaxy_test(.*) http://localhost:8081$1 [P]
RewriteRule ^/galaxy_test$ /galaxy_test/ [R]
RewriteRule ^/galaxy_test/static/style/(.*) /home/galaxy_test/galaxy/static/june_2007_style/blue/$1 [L]
RewriteRule ^/galaxy_test/static/scripts/(.*) /home/galaxy_test/galaxy/static/scripts/packed/$1 [L]
RewriteRule ^/galaxy_test/static/(.*) /home/galaxy_test/galaxy/static/$1 [L]
RewriteRule ^/galaxy_test/favicon.ico /home/galaxy_test/galaxy/static/favicon.ico [L]
RewriteRule ^/galaxy_test/robots.txt /home/galaxy_test/galaxy/static/robots.txt [L]

So when I tried to run it the first time I got the "temporarily out of service" error on my browser and the following error in apache log:

[Mon Oct 19 05:56:45.308714 2015] [proxy:error] [pid 18505] (13)Permission denied: AH00957: HTTP: attempt to connect to 127.0.0.1:8081 (*) failed
[Mon Oct 19 05:56:45.308774 2015] [proxy_http:error] [pid 18505] [client 185.25.151.159:39629] AH01114: HTTP: failed to make connection to backend: localhost

Searching the internet I found the following solution:

/usr/sbin/setsebool httpd_can_network_connect 1

/usr/sbin/setsebool -P httpd_can_network_connect 1

but when I restarted my galaxy my browser would now show just a blank page and the error log of apache was:

[Mon Oct 19 15:29:09.425120 2015] [proxy:error] [pid 29699] (111)Connection refused: AH00957: HTTP: attempt to connect to 127.0.0.1:8081 (*) failed
[Mon Oct 19 15:29:09.425167 2015] [proxy_http:error] [pid 29699] [client 147.102.86.121:51865] AH01114: HTTP: failed to make connection to backend: localhost


Has anyone encountered that?

Kind regards,
Makis






P.S. In case that helps the output of iptables -L is the following:
