redis 사용자 및 그룹 생성

groupadd redis

useradd -g redis redis

chown -R redis:redis /usr/local/redis

 

redis 기동 확인

---

redis 시작

su - redis 

/usr/local/redis/cluster/redis_start.sh

기동 확인

ps -ef | grep redis

 

redis cluster 구성

---

cluster 구성은 전체 서버가 아닌 한대만 설치해도 된다

 

cluster 구성용 redis-trib-pass 파일 다운로드

cd /usr/local/redis/src

wget https://raw.githubusercontent.com/seekasia/redis/master/src/redis-trib-pass.rb

redis-trib-pass.rb 첫번째 행 ruby2.1 => ruby 수정
vi redis-trib-pass.rb

chmod 700 redis-trib-pass.rb

ruby를 다운로드

cd /usr/local/src

wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.gz

tar xvf ruby-2.5.1.tar.gz

ruby 컴파일

yum install -y bzip2 gcc openssl-devel readline-devel zlib-devel

cd ruby-2.5.1/

./configure

make

make install 

ruby --version

gem install redis

마스터 서버 cluster 설정

*redis cluster 구성시 host name 이 아닌 Ip Address를 이용한다.

/usr/local/redis/src/redis-trib-pass.rb create --auth password 1.1.1.1:7000 1.1.1.2:7000 1.1.1.3:7000

cluster 확인 (마스터 ID 확인)

/usr/local/redis/src/redis-cli -p 7000 -a password cluster nodes

d6c9d17ba96137d13d0217a7e62ea7e7250a090e 1.1.1.1:7000@17000 myself,master - 0 0 1 connected 0-5460
5ac01a2c3936ef788fe63f8e9467156734b07aae 1.1.1.2:7000@17000 master - 0 1563850868038 2 connected 5461-10922
64908665fb8d8f966c5b0b3c82b60c7858db6d6e 1.1.1.3:7000@17000 master - 0 1563850868037 3 connected 10923-16383

* 첫번째 키가 마스터 키

 

slave 추가

#/usr/local/redis/src/redis-trib.rb add-node --slave --master-id <마스터ID>  --auth 비밀번호 <슬레이브IP:port> <현재실행서버IP:port>

 

예:

Cluster 1 master slave 설정

/usr/local/redis/src/redis-trib-pass.rb add-node --slave --master-id d6c9d17ba96137d13d0217a7e62ea7e7250a090e --auth password 1.1.1.2:7000 1.1.1.1:7000

/usr/local/redis/src/redis-trib-pass.rb add-node --slave --master-id d6c9d17ba96137d13d0217a7e62ea7e7250a090e --auth password 1.1.1.3:7000 1.1.1.1:7000

Cluster 2 master slave 설정

/usr/local/redis/src/redis-trib-pass.rb add-node --slave --master-id 5ac01a2c3936ef788fe63f8e9467156734b07aae --auth password 1.1.1.4:7000 1.1.1.1:7000

/usr/local/redis/src/redis-trib-pass.rb add-node --slave --master-id 5ac01a2c3936ef788fe63f8e9467156734b07aae --auth password 1.1.1.5:7000 1.1.1.1:7000

Cluster 3 master slave 설정

/usr/local/redis/src/redis-trib-pass.rb add-node --slave --master-id 64908665fb8d8f966c5b0b3c82b60c7858db6d6e --auth password 1.1.1.6:7000 1.1.1.1:7000

/usr/local/redis/src/redis-trib-pass.rb add-node --slave --master-id 64908665fb8d8f966c5b0b3c82b60c7858db6d6e --auth password 1.1.1.7:7000 1.1.1.1:7000
