[Mac M1] Redis 설치 및 실행
Redis는 Key-Value형태의 값을 저장할 수 있는 NoSQL이면서 memcached와 마찬가지인 인메모리 데이터베이스이다.
매우 빠른 속도로 I/O 작업을 할 수 있고 다양한 자료구조를 지원한다.
저번에 homebrew를 설치했기 때문에 너무나 쉽고 간단하게 작업할 수가 있다.
1. brew install redis

4. redis-cli
➜ ~ redis-cli
127.0.0.1:6379>
5. set, get
redis는 set key value 문법으로 작성한다.
get key 명령어를 통해 저장된 value값을 가져온다.
127.0.0.1:6379> set key1 "hello Minggu"
OK
127.0.0.1:6379> get key1
"hello Minggu"
127.0.0.1:6379>
6. append
append key value는 기존에 저장된 value값 뒤에 문자열을 추가할 수 있다.
127.0.0.1:6379> set key2 "minggu"
OK
127.0.0.1:6379> get key2
"minggu"
127.0.0.1:6379> append key2 " is Developer"
(integer) 18
127.0.0.1:6379> get key2
"minggu is Developer"
127.0.0.1:6379>
7. Set
127.0.0.1:6379> smembers set:mingguSet
(empty array)
127.0.0.1:6379> sadd set:mingguSet minggu
(integer) 1
127.0.0.1:6379> sadd set:mingguSet like
(integer) 1
127.0.0.1:6379> sadd set:mingguSet pokemon
(integer) 1
127.0.0.1:6379> sadd set:mingguSet pokemon game
(integer) 1
127.0.0.1:6379> smembers set:mingguSet
1) "like"
2) "game"
3) "pokemon"
4) "minggu"
127.0.0.1:6379>sadd 명령어를 통해 Set 자료구조를 이용할 수 있다.
중복을 허용하지 않는 Set 구조이기에 중간에 'pokemon'은 삭제되었다. 그리고 순서가 섞여 나온다는 것을 알 수 있다.
8. sortedSet
127.0.0.1:6379> zadd rank 1 A
(integer) 1
127.0.0.1:6379> zadd rank 1 B
(integer) 1
127.0.0.1:6379> zadd rank 1 C
(integer) 1
127.0.0.1:6379> zadd rank 1 D
(integer) 1
127.0.0.1:6379> zrange rank 0 -1
1) "A"
2) "B"
3) "C"
4) "D"
127.0.0.1:6379>zadd 명령어를 통해 가중치 값을 지정할 수 있다.
zrange 명령어는 출력 범위를 지정한다. (-1이면 뒤에서부터 시작)
9. HashMap
127.0.0.1:6379> hset user name minggu
(integer) 1
127.0.0.1:6379> hset user age 15
(integer) 1
127.0.0.1:6379> hset user address "Seoul"
(integer) 1
127.0.0.1:6379> hgetall user
1) "name"
2) "minggu"
3) "age"
4) "15"
5) "address"
6) "Seoul"
127.0.0.1:6379>hset 명령어를 통해 key - value값을 설정하고
hgetall {name}을 통해 값을 가져온다.
