What parameters should be enabled when setting up master slave and master master replication?

We also need to enable relay-log in order to use the second instance as a slave by setting the relay-log, relay-log-index and relay-log-info-file parameters, as well as master-info-file. Finally, the read_only parameter is set to 1 in order to make the slave instance read-only. Keep in mind that prior to MySQL 5.7.

Does MySQL support master master replication?

However, it is the master-master replication that has proven to be advantageous by enabling read/write operations from multiple servers. In this blog post, we will discuss how to perform MySQL master master replication. MySQL is one of the most used relational databases and setting up replication is simple.

What is master to master replication in MySQL?

MySQL replication is the process by which a single data set, stored in a MySQL database, will be live-copied to a second server. This configuration, called “master-slave” replication, is a typical setup.

How does master-master replication work?

Master-master replication (more generally -- multi-master replication) conceptually works by assuming that conflicts are not common and only keeping the entire system loosely consistent, asynchonously communication updates between masters, which ends up violating basic ACID properties.

What is slave DB?

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. ... If the changes are made to the master and slave at the same time, it is synchronous.

What is a master-slave configuration?

Master/slave is a model of asymmetric communication or control where one device or process (the "master") controls one or more other devices or processes (the "slaves") and serves as their communication hub.

What is master-master and master-slave replication?

Master-Master: This is similar to Master-Slave architecture, the only difference is that both the nodes are masters and replica at the same time i.e. there will be circular replication between the nodes. ... Master-Slave: In this, as each data has only one master, so consistency is not difficult.

Is MongoDB a master slave?

MongoDB Replica Set with Master-Slave Replication and Automated Failover. ... This selected DB will process all the incoming write operations, storing the information about them within its oplog, where they can be accessed and replicated by every secondary (slave) replica member for being applied to their data sets.

How do I know if mysql is master or slave?

1. Start the MySQL command-line utility on the slave server: # cd /opt/mysql/mysql/bin. # mysql -u root -p. Enter password: ...
2. Check the replication status using the show slave status command (the status of the slave server is conveyed by the Slave_IO_Running and Slave_SQL_Running column values): mysql> SHOW SLAVE STATUS \G;

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.
