Install operating system (just operating system, don't need to install Apache, MySQL, Python, and so on).
Disable SELinux.
Give us an account with sufficient privileges.
We will install everything by SSH access.
Notes
We prefer to have one dedicated server for GeneNetwork website.
We need account root or general user account with permanent "sudo/su" privilege, and access servers by SSH.
To set up GN, we definitely need sudo/su access to install dependent packages, SVN, copy MySQL files and Python source code files, chown, chgrp, chmod, modify GN config files, etc.
