How master slave works in mysql?
Replication works as follows:
- Whenever the master’s database is modified, the change is written to a file, the so-called binary log, or binlog.
- The master has a thread, called the dump thread, that continuously reads the master’s binlog and sends it to the slave.
Why is MySQL replication not working on Port 3307?
The MySQL replication between the gateway nodes doesn’t work. The setup script /opt/SecureSpan/Appliance/bin/create_slave.sh sets the replication port to 3307, but communication on these ports is not possible. Communication on the standard mysql port 3306 is possible.
Can a MySQL server replicate to a slave?
In others, successful SBR requires that any SQL features used be supported by both the master and the slave servers. For example, if you use a feature on the master server that is available only in MySQL 5.7 (or later), you cannot replicate to a slave that uses MySQL 5.6 (or earlier).
Is there a difference between Port 3306 and Port 3307?
There’s absolutely no difference between one port or another. A port is just a number you give to a software on the network to listen on. No rules are pre-define on it, it’s up to you to define them. Thanks for contributing an answer to Stack Overflow!
Do you need to set master or slave replication?
I have set master – slave replication. log-bin is enabled on master, and also replication user is created on master with replication rights. It shows error as below. Error Code: 1794. Slave is not configured or failed to initialize properly. You must at least set –server-id to enable either a master or a slave.
