of experience with MySQL. But now I have a problem that I can't get any further. After a new installation (VM) of the slave: MySQL master slave replication, version 5.7.33, Linux, slave fails to connect to master (error 1159), master reports "Got timeout reading communication packets". From the console of the slave, connect to master is possible without any problems. Only the server process seems to have this problem, so no firewall, no connectivity problems are involved. Any ideas?
how to setup different port for bin log fetching? docu?
I don't say you need to change the port number from default value to some other. Just check in the docs, if binlog fetching requires an additional port, and if it does, enable another port in the firewall
