How can I disable the Slave Server permanently?

[muratyilmaz.dev]

I have a cluster structure as below.

I don't want to use Slave Server anymore.
How can I permanently disable the Slave Server without breaking the build?

(Then I want to stop any unnecessary running services on the Slave Server. For example mysql)

Thank you.

DBMaster
DBSlave + Web Server
Phone Server 1
Phone Server 2

Remove the slave reporting options from system settings.

[carpenox]

go into mysql and "stop slave;"

[muratyilmaz.dev]

go into mysql and "stop slave;"

Replication returned error 1236 due to power supply interruption.
I already stopped the slave server.
but it seems like you have to tell the master.
Because master logs continue to work.

How do I completely stop replication?
