How do I restart MySQL master-slave replication?

You can use the following commands (on mysql prompt): mysql> STOP SLAVE; mysql> SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1; mysql> START SLAVE; mysql> SHOW SLAVE STATUS; The value 1 represents the number of statements to skip. You can do it repeatedly until the replication is fixed.

How do I start MySQL replication?

MySQL Master-Slave Replication: Starting Replication

2. On Slave, Restore the data snapshot. Set the Slave to start replication.

How does MariaDB replication work?

Replication in MariaDB uses as master-slave configuration and enables the binlog on the master server, where all data updations are done. ... On the slave server, a relay log is created using the same format as the binary log, and this is used to perform the replication.

What is master slave replication?

Master-slave replication enables data from one database server (the master) to be replicated to one or more other database servers (the slaves). The master logs the updates, which then ripple through to the slaves. ... Master-slave replication can be either synchronous or asynchronous.

What is master slave replication MySQL?

How master slave works in MySQL?

Replication works as follows:

1. Whenever the master's database is modified, the change is written to a file, the so-called binary log, or binlog. ...
2. The master has a thread, called the dump thread, that continuously reads the master's binlog and sends it to the slave.

How do I stop a mysql slave?

To stop processing of the binary log from the source, use STOP SLAVE : mysql> STOP SLAVE; When replication is stopped, the slave I/O thread stops reading events from the source's binary log and writing them to the relay log, and the SQL thread stops reading events from the relay log and executing them.

How do I sync master and slave?

The process of master-slave synchronization in MySQL is as follows:

1. The master server verifies the connection.
2. The master server opens a thread for the slave server.
3. The slave server notifies the master server of the master server log's offset bit.

What does reset slave do in mysql?

RESET SLAVE makes the replica forget its replication position in the source's binary log. This statement is meant to be used for a clean start: It clears the replication metadata repositories, deletes all the relay log files, and starts a new relay log file.
