2. Modify System SecurityΒΆ

  1. Disable SELinux on the Open OnDemand host you intend on running the web server on.


    If SELinux is not disabled on the web server host machine this can lead to permission errors when running the web applications. SELinux may also need to be disabled on the web server if you want to take advantage of certain software in your web applications such as being able to access a Lustre file system.

  2. Open ports 80 (http) and 443 (https) in the firewall, typically done with iptables.


    If using RHEL 7 you will need to either use the newer firewalld daemon and modify the firewall settings or disable it and install iptables.
