Monitoring Redis Cluster

Pre-monitoring operations

1. create a empty folder and add two files.

   redis.config

     port 6379
     cluster-enabled yes
     cluster-config-file nodes.conf
     cluster-node-timeout 5000
     appendonly yes
     bind 0.0.0.0
     protected-mode no
   

   docker-compose.yml

   services:
     redis-master-1:
       image: redis:latest
       container_name: redis-master-1
       command: ["redis-server", "/usr/local/etc/redis/redis.conf"]
       volumes:
         - ./redis.conf:/usr/local/etc/redis/redis.conf
       ports:
         - "1000:6379"
   
     redis-master-2:
       image: redis:latest
       container_name: redis-master-2
       command: ["redis-server", "/usr/local/etc/redis/redis.conf"]
       volumes:
         - ./redis.conf:/usr/local/etc/redis/redis.conf
       ports:
         - "2000:6379"
   
     redis-master-3:
       image: redis:latest
       container_name: redis-master-3
       command: ["redis-server", "/usr/local/etc/redis/redis.conf"]
       volumes:
         - ./redis.conf:/usr/local/etc/redis/redis.conf
       ports:
         - "3000:6379"
   
     redis-slave-1:
       image: redis:latest
       container_name: redis-slave-1
       command: ["redis-server", "/usr/local/etc/redis/redis.conf"]
       volumes:
         - ./redis.conf:/usr/local/etc/redis/redis.conf
       ports:
         - "1001:6379"
   
     redis-slave-2:
       image: redis:latest
       container_name: redis-slave-2
       command: ["redis-server", "/usr/local/etc/redis/redis.conf"]
       volumes:
         - ./redis.conf:/usr/local/etc/redis/redis.conf
       ports:
         - "2001:6379"
   
     redis-slave-3:
       image: redis:latest
       container_name: redis-slave-3
       command: ["redis-server", "/usr/local/etc/redis/redis.conf"]
       volumes:
         - ./redis.conf:/usr/local/etc/redis/redis.conf
       ports:
         - "3001:6379"
   
   networks:
     default:
       external:
         name: hertzbeat-redis-cluster

2. View the IP addresses of all containers from the network, which is required when building a cluster.

   docker-compose up -d
   docker network inspect hertzbeat-redis-cluste

               "187b879f73c473b3cbb82ff95f668e65af46115ddaa27f3ff1a712332b981531": {

                   ...
               },

                   ...
               }
           },

3. Go inside the container to build a Redis cluster.

   docker exec -it redis-master-1 /bin/bash

   redis-cli --cluster create \
   192.168.117.4:6379 \
   192.168.117.7:6379 \
   192.168.117.3:6379 \
   192.168.117.5:6379 \
   192.168.117.6:6379 \
   192.168.117.2:6379 \
   --cluster-replicas 1

4. Specific operations.

   Add a redis monitor center, fill require parameters.

   

   final effect.
