About MongoDB

• MongoDB MUST be installed on the HSS machine in distributed installation and make sure all entities are accessing to the that database.
• Please add UE infomation to webUI on the HSS machine.
• Please modify the MongoDB address (at the first line of free5gc.conf config file) for every entity.

Install AMF, SMF, HSS, PCRF

Please follow steps in Part A under Installation from free5GC Installation on KVM.

Install UPF

Please follow steps in Part A and Part B under Installation from free5GC Installation on KVM.

Execution Order

Please run UPF daemon before running SMF daemon.
