12th Chapter Redis-cluster Construction (redis-3.2.5)

Redis Cluster Technology

• redis2.x using client-side sharding technology
• redis3.x Using cluster clustering technology

First, the environment

• Os:centos7
• ip:10.211.55.4
• redis:3.2.5
• gem-redis:3.2.2

Second, build a cluster

1, this machine download redis-3.2.5.tar.gz

• Redis Official website: https://redis.io/download

2. Copy from native to 10.211.55.4

• SCP redis-3.2.5.tar.gz [Email protected]:/opt/

3, enter the 10.211.55.4, unzip the installation

• Tar-zxf/opt/redis-3.2.5.tar.gz
• cd/opt/ redis-3.2.5/
• Make && make install

4. Create a folder

• Mkdir/data/cluster-p
• cd/data/cluster/
• mkdir 7000 7001 7002 7003 7004 7005

5. Copy Modify configuration file

• Cp/opt/redis-3.2.5/redis.conf/data/cluster/7000/
• Vi/data/cluster/7000/redis.conf
  • Bind 10.211.55.4
  • Port 7004
  • Daemonize Yes
  • cluster-enabled Yes
  • Cluster-config-file nodes.conf
  • Cluster-node-timeout 15000
• Copy the redis.conf to 7001~7005, and modify the port number

6. Start 6 Redis instances

• cd/data/cluster/7000
• Redis-server redis.conf

Other similar.

7. Install Ruby dependencies

• Yum install ruby Rubygems-y

8, the local download installation Gem-redis

• Download: https://rubygems.org/gems/redis/versions/3.2.2
• Copy the Gem-redis to the 10.211.55.4
  • sCP redis-3.2.2.gem [email protected]:/opt/
• Installation: Gem install-l/opt/redis-3.2.2.gem

9. Copy the cluster management program to/usr/local/bin/

• Cp/opt/redis-3.2.5/src/redis-trib.rb/usr/local/bin/redis-trib

10. Create a cluster

• Redis-trib Create --replicas 1 10.211.55.4:7000 10.211.55.4:7001 10.211.55.4:7002 10.211.55.4:7003 10.211.55.4:7004 10.211.55.4:7005
  • --replicas 1: Create a Slave node for each master node in the cluster
  • The cluster requires at least 3 primary nodes for normal operation: The above is three main three from

11. Testing

Use RDM for connectivity testing.

Second, Java operation (Jediscluster)

Chapter III Springboot + Jediscluster
