🔥 우선 빠르게 docker-compose.yaml 파일을 소개해드리겠습니다
우선 저는 master node 3개, slave node 3개로 해서 redis cluster를 구성할 계획입니다.
일단, docker-compose.yaml 파일을 소개해드리겠습니다
🔨 docker-compose.yaml
version: '3'
services:
redis-master-1:
container_name: redis-master-1
image: redis:6.2.3
command: redis-server /etc/redis.conf
volumes:
- ./redis-master-1.conf:/etc/redis.conf
restart: always
ports:
- 7001:7001
- 17001:17001
redis-master-2:
container_name: redis-master-2
image: redis:6.2.3
command: redis-server /etc/redis.conf
volumes:
- ./redis-master-2.conf:/etc/redis.conf
restart: always
ports:
- 7002:7002
- 17002:17002
redis-master-3:
container_name: redis-master-3
image: redis:6.2.3
command: redis-server /etc/redis.conf
volumes:
- ./redis-master-3.conf:/etc/redis.conf
restart: always
ports:
- 7003:7003
- 17003:17003
redis-slave-1:
container_name: redis-slave-1
image: redis:6.2.3
command: redis-server /etc/redis.conf
volumes:
- ./redis-slave-1.conf:/etc/redis.conf
restart: always
ports:
- 7004:7004
- 17004:17004
redis-slave-2:
container_name: redis-slave-2
image: redis:6.2.3
command: redis-server /etc/redis.conf
volumes:
- ./redis-slave-2.conf:/etc/redis.conf
restart: always
ports:
- 7005:7005
- 17005:17005
redis-slave-3:
container_name: redis-slave-3
image: redis:6.2.3
command: redis-server /etc/redis.conf
volumes:
- ./redis-slave-3.conf:/etc/redis.conf
restart: always
ports:
- 7006:7006
- 17006:17006여기서 각 master는 7001~7003번으로 할당하였고, 각 slave는 7004~7006번으로 할당하였습니다.
그리고 각각의 설정파일을 루트폴더에 같이 넣어줍니다.
🔨 redis-master-1.conf
port 7001
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 3000
appendonly yes
bind 0.0.0.0
cluster-announce-ip [Your Server IP]여기서 각각마다 파일 이름을 변경해가며 port만 바꿔주면됩니다.
🔥 이제 cluster를 돌려봅시다
우선 docker, docker-compose를 설치한 뒤, 아래의 커맨드를 이용해 실행합니다
🔨 명령어
$ sudo docker-compose up -d
# 성태 확인
$ sudo docker container list # or, enter the "docker ps -a"🔨 결과

Hi There 🤗! I'm college student majoring Mathematics, and double majoring CSE. I'm just enjoying studying about good architectures of back-end system(applications) and how to operate the servers efficiently! 🔥
datagrip이나 dbeaver 와 같은툴에서는 어떻게 붙을 수 있나요?
redis-cli --cluster create [public IP]:7001 [public IP]:7002 [public IP]:7003 \
[public IP]:7004 [public IP]:7005 [public IP]:7006 \
--cluster-replicas 1
명령어에서 public IP 부분에는 어떤값을 넣어야 하는지 알수있을까용?
