Securing the MySQL / NFS Server


The DCA cluster needs to have access to a MySQL and an NFS Shared Volume to support the storage of policies, events, avatars and data files.

A Firewall is Required

The MySQL / NFS Server should employ a firewall to prevent unauthorized access to services on the server but that allow the DCA cluster to access the server.

Required Services

Services to open for the MySQL / NFS support server

The Required Services are:

  • ssh (Port 22)
  • http (Port 80)
  • https (Port 443)
  • mysql (Port 3306)
  • nfs (Ports 111,2049,32803)

The Uncomplicate Firewall (UFW) provides a simple solution for easily securing the Linix firewall on either fedora or debian based linux systems.
