MySQL master-slave replication, implemented on a single server

Now, the company replicates data from a single server. Now we know that you need to install multiple mysql services. Now, under the existing single-instance database, different ports are divided into the red section below;
[Root @ mysql ~] # Netstat-tunlp

When the above services are started normally, configure the master and slave nodes. I didn't adjust the IO thread. I don't know how to see the master-slave replication relationship on different ports. The following are the last errors I encountered during the configuration, please help me look at it and make a brick...
