network configuration questions
I'd like to clarify a few points about the network configuration in Openstack:
1.- Can the public network be the same as my physical LAN network so I get access to internet? If not, what is it?
2.- I saw, from the dashboard, there is public network with an IP that doesn't belong to my LAN and I can't edit it. What's the purpose of this network? Can I delete it?
3.- I'm trying to create a public network using the official documentation of OpenStack but it's just explained to do it through CLI. I log in through SSH to my OpenStack but it seems I don't have permissions to input commands. What's the best way to do this? When I try to input commands through SSH or through the CentOS console, I get this type of message: "Missing value auth-url required for auth plugin password"
4.- Regarding to ports, do I need to have a port in my public network to connect to my physical network? If I'm using a CentOS VM in VMWare, how can I know the type of port I need to select?
I know it's a lot of stuff but I'm not able to launch any instance and I believe it's because my networks/subnetworks/ports configuration is wrong or incomplete. I'd just like to have a basic network configuration that works.
How did you create this cloud?
Q1/2: Yes, usually an external network (public is not an OpenStack term) corresponds to a physical network outside of the cloud, but clouds created for testing, learning or POC often fake the external network.
Q3: What happens when you try to input commands?
Q4: What do you mean by "port"? Neutron ports are used to connect routers, instances, DHCP servers etc to a network, not to associate an external network with a physical network.
Q1: you can create same public network or u can have virtual router. Q2: Its default network you can delete it, its dummy one. Q3: source your keystone.rc file then run cli command. Q4: Normal type ovs.
Thanks, guys!! To do this deployment, I followed this guide step by step: https://linuxhint.com/install_openstack_vmware_esxi/ (https://linuxhint.com/install_opensta...)
When I input the commands through SSH or through the console of the CentOS, I get this messahe: "Missing value auth-url required for auth plugin password"
