Redis - Cluster Master Node 구성정보

Redis - Cluster Master Node 설정하기

1. Redis - Clustering 폴더 생성

mkdir redis-cluster
cd redis-cluster

2. Redis - Cluster Master Node 설정파일 생성

# cp /etc/redis/redis.conf 7000-cluster.conf

# cp /etc/redis/redis.conf 7100-cluster.conf

# cp /etc/redis/redis.conf 7200-cluster.conf

3. Redis - Cluster Master Node1, Node2, Node3 설정파일 수정

3-1) Cluster - Master Node1

vi 7000-cluster.conf

port 7000
daemonize yes
cluster-enabled yes 
cluster-config-file nodes-7000.conf 
cluster-node-timeout 3000 
appendonly yes 
appendfilename appendonly_7000.aof 
pidfile /var/run/redis_7000.pid
logfile logs/redis_7000.log

3-2) Cluster - Master Node2

vi 7100-cluster.conf

port 7100
daemonize yes
cluster-enabled yes 
cluster-config-file nodes-7100.conf 
cluster-node-timeout 3000 
appendonly yes 
appendfilename appendonly_7100.aof 
pidfile /var/run/redis_7100.pid
logfile logs/redis_7100.log

3-3) Cluster - Master Node3

vi 7200-cluster.conf

port 7200
daemonize yes
cluster-enabled yes 
cluster-config-file nodes-7200.conf 
cluster-node-timeout 3000 
appendonly yes 
appendfilename appendonly_7200.aof 
pidfile /var/run/redis_7200.pid
logfile logs/redis_7200.log

4. Redis - Master Node1, Node2, Node3 - Cluster 실행

# redis-server 7000-cluster.conf

# redis-server 7100-cluster.conf

# redis-server 7200-cluster.conf

5. Redis - Cluster 프로세스 확인

# ps -ef | grep redis
root      197823       1  0 18:20 ?        00:00:05 redis-server 0.0.0.0:7000 [cluster]
root      197830       1  0 18:21 ?        00:00:05 redis-server 0.0.0.0:7100 [cluster]
root      197837       1  0 18:21 ?        00:00:05 redis-server 0.0.0.0:7200 [cluster]
root      197902  197296  0 19:01 pts/1    00:00:00 grep --color=auto redis

6. Redis - Cluster Master Node 생성하기

사용법 : redis-cli --cluster create [Master Node1 IP]:[Master Node1 Port] [Master Node1 IP]:[Master Node2 Port] [Master Node1 IP]:[Master Node3 Port]

# redis-cli --cluster create 127.0.0.1:7000 127.0.0.1:7100 127.0.0.1:7200
