Configuring Replication in Redis
Explore how to configure replication in Redis by setting up Redis instances as replicas using configuration files and commands. Understand the use of read-only replicas, authentication between master and slave, and how to manage replication settings to ensure data integrity and reduce loss. This lesson helps you gain hands-on knowledge of advanced replication options such as minimum slave requirements and lag management.

In the previous lesson, we discussed the concept of replication in Redis. Now it is time to see how replication can be configured in Redis. There are two ways to configure a Redis server as a slave.
- Provide the
slaveofproperty in theredis.conffile. This property takes two parameters, i.e., the host and the port of the master. An example of how this can be written in the conf file is shown below.
slaveof127.0.0.1 6379
When this Redis instance is started, it will automatically connect to the master server.
- We can use the
REPLICAOFcommand to convert a Redis instance into a slave. Here are a few important points about this command:
- REPLICAOF hostname port will make
