GitHub - joyieldInc/predixy: A high performance and fully featured proxy for redis, support redis sentinel and redis cluster

 

predixy

redis cluster 및 sentinel 을 위한 프록시

 

1. 설치

git clone https://github.com/joyieldInc/predixy
cd predixy
make
cp src/predixy /path/to/bin

predixy -h

 

2. predixy 구성도

(predixy 가 key 에 맞는 레디스 서버로 알아서 접근)

predixy

 

 

3. conf 설정 (predixy)
(predixy/conf)

cluster.conf

## Examples:
ClusterServerPool {
    MasterReadPriority 60
    StaticSlaveReadPriority 50
    DynamicSlaveReadPriority 50
    RefreshInterval 1
    ServerTimeout 1
    ServerFailureLimit 10
    ServerRetryTimeout 1
    KeepAlive 120
    Servers {
	+ ip:6300
	+ ip:6300
	+ ip:6300
 	+ ip:6400
	+ ip:6400
	+ ip:6400
    }
}

 

4. redis conf 설정

(/etc/redis)

# 두개 생성
redis_master_6300.conf
redis_slave_6400.conf

port 각자포트
# port 6300 port 6400

bind 0.0.0.0
daemonize yes
cluster-enabled yes
 
cluster-config-file nodes-[각자포트].conf 
# cluster-config-file nodes-6300.conf cluster-config-file nodes-6400.conf
 
cluster-node-timeout 3000
 
pidfile /var/run/redis/redis_[각자포트].pid
# /var/run/redis/redis_6300.pid /var/run/redis/redis_6400.pid

logfile /var/log/redis/redis_[각자포트].log
# /var/log/redis/redis-master-6300.log /var/log/redis/redis-master-6400.log

 

5. systemd (redis-master, redis-slave)

( /etc/systemd/system )

 

# redis-master.service
# redis-slave.service

# master

6. cluster (redis-cli)

# master node 생성 (최소 3개 필요)

redis-cli --cluster create ip:6300 ip:6300 ip:6300

# cluster
redis-cli --cluster add-node ip:6400 ip:6300
redis-cli --cluster add-node ip:6400 ip:6300
redis-cli --cluster add-node ip:6400 ip:6300


# 참고
# Reset cluster

# master
redis-cli --cluster call ip:6300 flushall
redis-cli --cluster call ip:6300 cluster reset
redis-cli --cluster call ip:6300 flushall
redis-cli --cluster call ip:6300 cluster reset
redis-cli --cluster call ip:6300 flushall
redis-cli --cluster call ip:6300 cluster reset

# slave
redis-cli --cluster call ip:6400 cluster reset
redis-cli --cluster call ip:6400 cluster reset
redis-cli --cluster call ip:6400 cluster reset
