### Install Control plane

This can run in any cluster. A mesh should have at least one cluster should run Pilot or equivalent XDS server,
and it is recommended to have Pilot running in each region and in multiple availability zones for multi cluster.

	h.wg.Wait()

	// Set logch to nil and close it.

	// All future ones will be discarded.
	h.logChMu.Lock()
	xioutil.SafeClose(h.logCh)
	h.logCh = nil
	h.logChMu.Unlock()

        And there's a high chance that you will find the solution along the way and you won't even have to submit it and wait for an answer. 😎

        As there are too many questions, I'll have to discard and close the incomplete ones. That will allow me (and others) to focus on helping people like you that follow the whole process and help us help you. 🤓

This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use

```sh
firewall-cmd --zone=public --add-port=9000/tcp --permanent
```
