Do you need a slave for MySQL replication?

Do you need a slave for MySQL replication?

It is customary to use a dedicated MySQL user to read replication statements from the Master. All this user needs is the “replication slave” privilege. Let’s do this while we’re in this session: I’ll name mine “replicator” and give it a good password.

How to re-sync the MySQL db if master and slave have?

Mysql Server1 is running as MASTER. Mysql Server2 is running as SLAVE. Now DB replication is happening from MASTER to SLAVE. Server2 is removed from network and re-connect it back after 1 day. After this there is mismatch in database in master and slave.

Why does MySQL replication fail when the machine restarts?

A replication slave needs some of its temporary files to survive a machine restart so that it can replicate temporary tables or LOAD DATA INFILE operations. If files in the temporary file directory are lost when the server restarts, replication fails.

How does MySQL copy user accounts from master to slave?

A note on user accounts: each database has its own directory in /var/lib/mysql – including a database called “mysql”. This is MySQL’s own database in which it stores users and their privileges. Hence, when you import all your previous databases into the slave, you’ll automatically copy all user accounts from the master too.

Is it easy to sync development and Production databases?

The easiest way to create a development database is to sync it regularly with a production database. You will only need to configure such a synchronization process once, and the data in your development database will be as close to reality as possible.

How is master table replicated to slave server?

The copy of master table is replicated to slave servers or customers who are authorized to view, read, search data. Any write operation instructed by consumer is transferred to master server and it does changes demanded. Hence we can infer that these applications provide slaves with read-only feature and where writes are done only by master.

What’s the difference between single master and multi master replication?
