First install redis on a single machine for the three machines, and then perform the following steps
Master 192.168.1.102
Slaver 192.168.1.104
Slaver 192.168.1.105
Modify the redis.conf configuration files of two slaver to add master configuration information
Slaveof 192.168.1.102 6379
Start three machines
Sudo. / redis-server redis.conf
Then check the information of the primary node
. / redis-cli-h 192.168.1.102 info Replication
Then check the information of the slave node.
. / redis-cli-h 192.168.1.105 info Replication
At this point, verify whether the master and slave are synchronized.
Insert data on the master connection client to see if there is data in the slaver
You can see that the master and slave have been able to successfully synchronize data
192.168.1.106
Configure sentinel
Sentinel needs to be copied over.
Cp src/redis-sentinel / usr/redis/
Cp sentinel.conf / usr/redis/

Modify settings master address and port number
Sentinel monitor mymaster 192.168.1.102 6379 2
Save
Then copy three configuration files
Sentinel1.conf sentinel2.conf sentinel3.conf
The port numbers are 26379, 36379, and 46379 respectively.
Start three processes respectively
. / redis-sentinel sentinel1.conf
. / redis-sentinel sentinel2.conf
. / redis-sentinel sentinel3.conf
Test cluster
Shut down the redis service of 192.168.1.102
View the information of 192.168.1.104 which was originally slaver on 192.168.1.106
. / redis-cli-h 192.168.1.104 info Replication
You can see that 192.168.1.104 has become master,slaver is 192.168.1.105
Reconnect 192.168.1.102
Found that 192.168.1.102 has become a slave node
So far, the whole cluster has been built.
