spring-learn-redis-cluster

This Project's Goal, Redis-Cluster used with Spring-Boot

Installation

• First,Run docker-compose.yaml Without Application

  • docker-compose up -d redis1 redis2 redis3 redis4 redis5 redis6

  

• Second,Find ip addresses of redis containers

  • docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

  

• Third,Enter the container with exec command,

  • docker exec -it redis1 bash

• Fourth,Create Redis Cluster

  • redis-cli --cluster create "redis1 IP Address":6379 "redis2 IP Address":6379 "redis3 IP Address":6379 "redis4 IP Address":6379 "redis5 IP Address":6379 "redis6 IP Address":6379 --cluster-replicas 1

• Fifth,define Redis's dependencies in pom.xml

  <!--Cache-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <version>${redis.version}</version> 3.0.0
        </dependency>

        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>${jedis.version}</version> 3.9.0
        </dependency>

• Sixth,open application.properties and configure redis settings

spring.data.redis.cluster.nodes = redis1:6379,redis2:6379,redis3:6379, redis4:6379, redis5:6379, redis6:6379
spring.data.redis.cluster.max-redirects = 3

• Seventh,Open RedisClusterConfig and edit the settings here according to application.properties (Note:getClusterNodes() method is Optional)

• Eighth,open Dockerfile and configure Owner settings,

• Added application build in docker-compose.yaml and run docker-compose up -d --build
