How to publish a local block chain

[llwinner]

If I run ignite network chain publish github.com/ignite/example, the chain is published on ignite chain, is that right?
I want to publish a local block chain, I didn't find any docs about it. When I saw the global flag: --local and --spn-node-address, I guess maybe I can build a local block chain.
But when I run ignite n chain list --spn-node-address http://127.0.0.1:26657/ , I got an error: Rpc error: code = Unknown desc = unknown query path: unknown request
I run ignite n chain list --spn-node-address http://127.0.0.1:26657/ --local, I got another error: Error while requesting node 'http://0.0.0.0:26661/': post failed: Post "http://0.0.0.0:26661/": dial tcp 0.0.0.0:26661: connect: connection refused
Can ignite publish a local block chain?
How should I build my local spn?
I run ignite chain serve and get tendermint endpoint http://localhost:25567/, is that the address of local spn?
Please help me.
