Redis - Slave Node Cluster 구성정보

Redis - Slave Node Cluster 설정하기

1. Redis - Clustering Slave 폴더 생성

mkdir redis-cluster-slave
cd redis-cluster-slave

2. Redis - Cluster Slave Node 설정파일 생성

# cp /etc/redis/redis.conf 8000-slave.conf

# cp /etc/redis/redis.conf 8100-slave.conf

# cp /etc/redis/redis.conf 8200-slave.conf

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

3-1) Cluster - Slave Node1

vi 8000-slave.conf

port 8000
daemonize yes
cluster-enabled yes 
cluster-config-file nodes-8000.conf 
cluster-node-timeout 3000 
appendonly yes 
appendfilename appendonly_8000.aof 
pidfile /var/run/redis_8000.pid
logfile logs/redis_8000.log

3-2) Cluster - Slave Node2

vi 8100-slave.conf

port 8100
daemonize yes
cluster-enabled yes 
cluster-config-file nodes-8100.conf 
cluster-node-timeout 3000
appendonly yes 
appendfilename appendonly_8100.aof 
pidfile /var/run/redis_8100.pid
logfile logs/redis_8100.log

3-3) Cluster - Slave Node3

vi 8200-slave.conf

port 8200
daemonize yes
cluster-enabled yes 
cluster-config-file nodes-8200.conf 
cluster-node-timeout 3000
appendonly yes 
appendfilename appendonly_8200.aof 
pidfile /var/run/redis_8200.pid
logfile logs/redis_8200.log

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

# redis-server 8000-slave.conf

# redis-server 8100-slave.conf

# redis-server 8200-slave.conf

5. Redis - Slave Cluster 프로세스 확인

# ps -ef | grep redis
root      212140       1  0 19:11 ?        00:00:03 redis-server 127.0.0.1:7000 [cluster]
root      212145       1  0 19:11 ?        00:00:03 redis-server 127.0.0.1:7100 [cluster]
root      212156       1  0 19:12 ?        00:00:03 redis-server 127.0.0.1:7200 [cluster]
root      214508       1  0 19:38 ?        00:00:00 redis-server 127.0.0.1:8000 [cluster]
root      214513       1  0 19:38 ?        00:00:00 redis-server 127.0.0.1:8100 [cluster]
root      214518       1  0 19:38 ?        00:00:00 redis-server 127.0.0.1:8200 [cluster

6. Redis - Slave Node와 Master Node 연결하기

사용법 : redis-cli --cluster add-node [Slave Node IP]:[Slave Node Port] [Master Node1 IP]:[Master Node1 Port] --cluster-slave

# redis-cli --cluster add-node 127.0.0.1:8000 127.0.0.1:7000 --cluster-slave

# redis-cli --cluster add-node 127.0.0.1:8100 127.0.0.1:7100 --cluster-slave

# redis-cli --cluster add-node 127.0.0.1:8200 127.0.0.1:7200 --cluster-slave

# redis-cli --cluster add-node 127.0.0.1:8000 127.0.0.1:7000 --cluster-slave
