Description : Redis is an advanced key-value store. It is often referred to as a data
            : structure server since keys can contain strings, hashes, lists, sets and
            : sorted sets.
            :
            : You can run atomic operations on these types, like appending to a string;
            : incrementing the value in a hash; pushing to a list; computing set
            : intersection, union and difference; or getting the member with highest
            : ranking in a sorted set.
            :
            : In order to achieve its outstanding performance, Redis works with an
            : in-memory dataset. Depending on your use case, you can persist it either
            : by dumping the dataset to disk every once in a while, or by appending
            : each command to a log.
            :
            : Redis also supports trivial-to-setup master-slave replication, with very
            : fast non-blocking first synchronization, auto-reconnection on net split
            : and so forth.
            :
            : Other features include Transactions, Pub/Sub, Lua scripting, Keys with a
            : limited time-to-live, and configuration settings to make Redis behave like
            : a cache.
            :
            : You can use Redis from most programming languages also.

Redis 설치

remi 저장소를 활성화한 후 Redis를 설치합니다.

sudo yum install -y redis

Redis 버전 확인

redis-cli --version

$ redis-cli --version
redis-cli 6.2.5

Redis 서비스 시작 및 부팅 시 자동 시작 설정

sudo systemctl --now enable redis

Redis 상태 확인

sudo systemctl status redis

Redis 구성 확인

sudo vim /etc/redis.conf

bind 0.0.0.0

레디스 설치 후 기본 구성 설정(redis default configuration settings)

TCP backlog 경고

sysctl -w net.core.somaxconn=1024

(또는)

echo "net.core.somaxconn = 1024" >> /etc/sysctl.conf

overcommit_memory 경고

sysctl -w vm.overcommit_memory=1

(또는)

echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf

THP 경고

echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local

Redis 클라이언트로 접속 테스트

Redis가 제대로 설치되고 실행되고 있는지 확인하기 위해 Redis 클라이언트를 사용하여 접속해 볼 수 있습니다.

redis-cli

Redis 클라이언트가 실행되면 PING 명령을 입력하여 응답을 확인합니다.
