Redis 4.x Cookbook

How to do it...

The first way to perform a single Redis instance to another single Redis instance migration works as follows:

1. First, let's start two Redis instances:

$ bin/redis-server conf/redis.conf$ bin/redis-server conf/redis2.conf$ ps -ef |grep redis-serverredis 361 32707 0 14:14 pts/5 00:00:00 grep redis-serverredis 21413 1 0 Dec10 ? 00:03:10 bin/redis-server 0.0.0.0:6379redis 32762 1 0 14:13 ? 00:00:00 bin/redis-server 0.0.0.0:6380127.0.0.1:6379> info Keyspace# Keyspacedb0:keys=1000000,expires=0,avg_ttl=922042600

2. By acting as a slave of the source instance, we can replicate all the data from the source Redis:

127.0.0.1:6380> SLAVEOF 192.168.1.7 6379OK127.0.0.1:6380> info Keyspace# Keyspacedb0:keys=1000000,expires=0,avg_ttl=922042600 ...
