06 redis cluster structures

Foreword

Ha ha recently there are a series of related requirements for environment construction

Record it

redis three nodes: 192.168.110.7, 192.168.110.8

7 open three redis instances, 8 open three redis instances

All three machines are trusted shell

redis is based on 5.0.8

Redis cluster building

redis two nodes: 192.168.110.7, 192.168.110.8

1. Basic environment preparation

192.168.110.7, 192.168.110.8 Install jdk on it, upload the redis installation package

The installation package is from Download | Redis

2. redis configuration adjustment

Sample 7001's configuration file below, 7001 - 7006's configuration file is similar

[[email protected] redis-5.0.8]# cat redis_7001.confprotected-mode noport 7001daemonize yessupervised nopidfile /var/run/redis_7001.pidlogfile "/var/log/redis/redis_7001.log"dir /meiya/data/redis/redis_7001appendonly yesappendfsync alwayscluster-enabled yescluster-config-file nodes_7001.confcluster-node-timeout 15000

Create startCluster.sh on 192.168.110.7 and 192.168.110.8 respectively

192.168.110.7 is as follows

./bin/redis-server ./redis_7001.conf./bin/redis-server ./redis_7002.conf./bin/redis-server ./redis_7003.conf#./bin/redis-server ./redis_7004.conf#./bin/redis-server ./redis_7005.conf#./bin/redis-server ./redis_7006.conf#./bin/redis-cli --cluster create 192.168.110.7:7001 192.168.110.7:7002 192.168.110.7:7003 192.168.110.8:7004 192.168.110.8:7005 192.168.110.8:7006 --cluster-replicas

192.168.110.8 is as follows

# ./bin/redis-server ./redis_7001.conf# ./bin/redis-server ./redis_7002.conf# ./bin/redis-server ./redis_7003.conf./bin/redis-server ./redis_7004.conf./bin/redis-server ./redis_7005.conf./bin/redis-server ./redis_7006.conf./bin/redis-cli --cluster create 192.168.110.7:7001 192.168.110.7:7002 192.168.110.7:7003 192.168.110.8:7004 192.168.110.8:7005 192.168.110.8:7006 --cluster-redis-cli

4. Start the cluster

Execute startCluster.sh on 192.168.110.7

Then execute startCluster.sh on 192.168.110.8

If there is no exception, the cluster will start successfully

Test cluster

[[email protected] redis-5.0.8]# ./bin/redis-cli -p 7004 -c127.0.0.1:7004> get name-> Redirected to slot [5798] located at 192.168.110.7:7003"jerry"192.168.110.7:7003> get name"jerry"192.168.110.7:7003> set name zerryOK192.168.110.7:7003> get name"zerry"192.168.110.7:7003>
