작업 순서

---

1. Redis 다운로드 및 설치

wget http://download.redis.io/releases/redis-5.0.5.tar.gz
gzip -d redis-5.0.5.tar.gz
tar xvf redis-5.0.5.tar
cd redis-5.0.5
redis-5.0.5]# make
mv redis-5.0.5 /usr/local/redis

2. Redis 유저 / 그룹 생성

-- redis 유저 / 그룹 생성 공통
groupadd redis
adduser -g redis redis

2-1 폴더 생성

mkdir -p /usr/local/redis/cluster/7000
mkdir -p /usr/local/redis/cluster/conf
cd /usr/local/redis/cluster/conf

 

3. config 파일 생성

vi redis.7000.conf

4. Redis 실행

- 경로이동

cd /usr/local/redis/cluster

 

# 실행 스크립트 생성
vi redis_start.sh
#!/bin/bash
 
/usr/local/redis/src/redis-server /usr/local/redis/cluster/conf/redis.7000.conf &

chmod +x redis_start.sh
chown -R redis:redis /usr/local/redis

5. 클러스터 생성

# 클러스터 생성
# 1.1.1.2:7000를 1.1.1.1:7000의 슬레이브로 지정
./redis-cli --cluster create 1.1.1.1:7000 1.1.2.1:7000 1.1.3.1:7000
./redis-cli --cluster add-node 1.1.1.2:7000 1.1.1.1:7000 --cluster-slave
./redis-cli --cluster add-node 1.1.2.2:7000 1.1.2.1.213:7000 --cluster-slave
./redis-cli --cluster add-node 1.1.3.2:7000 1.1.3.1:7000 --cluster-slave

728x90

5-1 유저 스위칭 후 수행

# redis 유저로 변경하여 실행
sudo su redis
./redis_start.sh

 

6. 클러스터 확인

cd /usr/local/redis/src
./redis-cli --cluster check 1.1.1.1:7000
1.1.1.1:7000 (c6643cb1...) -> 0 keys | 5461 slots | 1 slaves.
1.1.2.1:7000 (1c9669af...) -> 0 keys | 5461 slots | 1 slaves.
1.1.3.1:7000 (f20cc469...) -> 0 keys | 5462 slots | 1 slaves.
[OK] 0 keys in 3 masters.
0.00 keys per slot on average.
