SELinux policies are very strict on CentOS by default. Apache isn't allowed to access files outside of its standard directories, nor access network resources. Your local Galaxy apps server is a network resource - even though it's local.
If you want to keep SELinux on then use audit2allow to see what policies will enable access: cat /var/log/audit/audit.log | audit2allow -v Then you can use setsebool (temporary) and setsebool -P (permanent) to enable. -- David Trudgian Ph.D. Computational Scientist, BioHPC UT Southwestern Medical Center Dallas, TX 75390-9039 Tel: (214) 648-4833 From: galaxy-dev [mailto:galaxy-dev-boun...@lists.galaxyproject.org] On Behalf Of Makis Ladoukakis Sent: Friday, October 23, 2015 10:30 AM To: Juan Carlos <jcsanch...@gmail.com> Cc: galaxy-...@lists.bx.psu.edu Subject: Re: [galaxy-dev] FW: Galaxy on Centos via Apache - connection refused Hello, That didn't work.
