Redis 실행

redis 실행 파일은 redis-server.exe이다. redis-server.exe 파일을 클릭하면 아래와 같이 바로 6379 포트로 redis가 실행된다.
[ Redis ] Window에 redis 설치해서 사용하기
스프링 부트의 캐싱 기능을 사용하다보니 분산 캐싱 기능도 사용해보고 싶어졌다. 분산 캐싱에 사용할 캐시 데이터 저장 공간은 여러 가지를 사용하는데, 그 중 Redis라는 것을 사용해보려고 한다. Redis란? Redis에 대해 간단하게 설명하면 Redis는 key-value와 같이 Map과 데이터를 저장하고 관리한다. 즉 캐시 데이터와 같이 key 값이 있는 데이터를 저장하기 좋은 것이다. 또한 redis 자체에서 저장된 데이터를 검색 및 제거할 수 있는 등 데이터 관리도 redis를 통해 할 수 있다. https://redis.io/download Redis *Download Stable releases liberally follow the usual major.minor.patch semantic v..

내 컴퓨터에서 경로 → C:\Program Files\Redis

근데, 난 안 열림,, ㅋㅋㅎㅎ

다른 방법 : cmd 창을 관리자 모드로 열어서 아래 명령어 입력 → 얘도 오류났음
C:\windows\system32>redis-server.exe redis.windows.conf Invalid argument during startup: Failed to open the .conf file: redis.windows.conf CWD=C:\windows\system32

C:\windows\system32>redis-server.exe [480360] 28 Mar 15:44:36.716 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server.exe /path/to/redis.conf [480360] 28 Mar 15:44:36.719 # Creating Server TCP listening socket *:6379: bind: No such file or directory

해결
◦
cmd에서 redis를 사용하기 위해 윈도우 redis 서비스 등록
▪
cmd 창을 열어 redis폴더로 이동
cd 주소 (나는 C:\Program Files\Redis)
C++
복사
▪
아래 명령어를 실행하여 윈도우에 redis를 서비스로 등록
•
출처에 있는 명령어로는 안되었는데 아래 거로 해서 성공함
redis-server --service-install --service-name redis-service --loglevel verbose
C++
복사
•
아래 사진처럼 뜨면 성공
◦
레디스 서버 켜기/끄기 → 이 단계 뛰어넘고 그냥 실행파일 열어서 실행시킴
redis-server --service-start redis-server --service-stop
C++
복사
◦
redis 폴더에서 redis-cli.exe 파일을 실행 → 실행 성공!!!!

참고
5분 안에 구축하는 Redis(레디스)
레디스(Remote Dictionary Server)가 무엇인가! - 메모리 기반 저장 서비스 - 키-값 구조 - 문자열만 저장할 수 있는 Memcached와 달리 다양한 자료구조(Collection: 목록성 데이터 처리 구조) 지원 -> 다양한 형식으로 저장 가능 (String, Set, Sorted Set, Hash, List 등) - 오픈 소스 (무료) - 원격(Remote) 저장소로 여러 서버에서 같은 데이터를 공유할 수 있음 - 캐시로 사용 가능 - 메모리에만 저장하는 Memcached와 달리 디스크에도 저장하여 데이터 저장소로 사용 가능 (백업 방식으로 2가지가 존재함.) > 개념만 봤을때 아 ~ 그렇구나 정도지 실제 해보지 않으면 알기 어렵다.. (다음번에 테스트 해볼 예정) RDB AOF ..

Jedis 보다 Lettuce 를 쓰자
Java의 Redis Client는 크게 2가지가 있습니다. Jedis Lettuce 둘 모두 몇천개의 Star를 가질만큼 유명한 오픈소스입니다. 이번 시간에는 둘 중 어떤것을 사용해야할지에 대해 성능 테스트 결과를 공유하고자 합니다. 모든 코드와 Beanstalk 설정값은 Github에 있으니 참고하세요. 레디스외 병목현상을 방지하기 위해 Nginx, 커널 파라미터 등은 모두 적절하게 튜닝된 상태입니다. 0. 프로젝트 환경 의존성 환경은 아래와 같습니다. Spring Boot 2.1.4 Spring Boot Data Redis 2.1.4 Jedis 2.9.0 Lettuce 5.1.6 그리고 테스트에 사용될 Redis Entity 코드는 아래와 같습니다. @ToString @Getter @RedisHas..
