redis的5大数据类型

redis五大类型都有key，或者将key理解为java中一个对象
基础指令基本为 COMMAND KEY_NAME

• 五大数据类型分别为String，Hash，List，Set，SortedSet

1. 字符串String
   redis 127.0.0.1:6379> SET runoobkey redis
OK
redis 127.0.0.1:6379> GET runoobkey
"redis"
2. 哈希表Hash
   redis 127.0.0.1:6379> HSET myhash field1 "foo"
OK
redis 127.0.0.1:6379> HGET myhash field1
"foo"
3. 列表List
   redis 127.0.0.1:6379> LPUSH runoobkey redis
(integer) 1
redis 127.0.0.1:6379> LPUSH runoobkey mongodb
(integer) 2
redis 127.0.0.1:6379> LPUSH runoobkey mysql
(integer) 3
redis 127.0.0.1:6379> LRANGE runoobkey 0 10
1) "mysql"
2) "mongodb"
3) "redis"
4. 集合Set
   redis 127.0.0.1:6379> SADD runoobkey redis
(integer) 1
redis 127.0.0.1:6379> SADD runoobkey mongodb
(integer) 1
redis 127.0.0.1:6379> SADD runoobkey mysql
(integer) 1
redis 127.0.0.1:6379> SADD runoobkey mysql
(integer) 0
redis 127.0.0.1:6379> SMEMBERS runoobkey
1) "mysql"
2) "mongodb"
3) "redis"
5. 有序集合SortedSet
   redis 127.0.0.1:6379> ZADD runoobkey 1 redis
(integer) 1
redis 127.0.0.1:6379> ZADD runoobkey 2 mongodb
(integer) 1
redis 127.0.0.1:6379> ZADD runoobkey 3 mysql
(integer) 1
redis 127.0.0.1:6379> ZADD runoobkey 3 mysql
(integer) 0
redis 127.0.0.1:6379> ZADD runoobkey 4 mysql
(integer) 0
redis 127.0.0.1:6379> ZRANGE runoobkey 0 10 WITHSCORES
1) "redis"
2) "1"
3) "mongodb"
4) "2"
5) "mysql"
6) "4"
