Hi all I'm deployment Openstack Ocata with / 1 Controller node / 1 Block storage / 2 Object storage / 2 compute / 1 Network node

But i cannot searching document openstack tutorial deployment with 1 network node (except using packstack rdo). Please help me install and configure openstack Ocata with Network node seperate.

After confgiure Network node and Controller node im type command "neutron ext-list" then show warnings:

neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. Connection to neutron failed: Failed to connect Neutron server

A separate network node is useful if Neutron-related processing overwhelms your controller. In particular if you use centralized routers instead of DVR, since most network traffic to and from instances goes through one server.

If you use DVR, or just a few compute nodes, I strongly doubt you need a network node. If, however, you want to try setting one up, this is not really different from running Neutron on the controller; just install and configure all Neutron components on that node. Pre-Liberty installation tutorials did that, though they kept neutron-server on the controller. If you want to read old tutorials, you may be able to build them according to

The neutron CLI is indeed deprecated, but still supported as of Queens, I think. If you fail to connect to the neutron server, you need to check if it is running at all, if networking and firewall configuration allows you to reach it, and if the endpoints configured in the service catalog correspond to the neutron-server configuration. Start with curl http://IPADDRESS:9696, where IPADDRESS is the address in the catalog.
