hash數據類型的相關命令
1，hset命令
127.0.0.1:6379> hset user name yuhao
(integer) 1
127.0.0.1:6379> hset user age 19
(integer) 1
127.0.0.1:6379> hset user from qinghai
(integer) 1
127.0.0.1:6379> hgetall user
1) "name"
2) "yuhao"
3) "age"
4) "19"
5) "from"
6) "qinghai"

2，hmset設定多項值
127.0.0.1:6379> hmset user1 name gss age 19
OK
查看某列值
127.0.0.1:6379> hget user1 name
"gss"
查看全部
127.0.0.1:6379> hgetall user1
1) "name"
2) "gss"
3) "age"
4) "19"

3，刪除一個值
127.0.0.1:6379> hdel user1 age
(integer) 1
127.0.0.1:6379> hget user1 age
(nil)

4，統計
127.0.0.1:6379> hlen user
(integer) 3
127.0.0.1:6379> hlen user1
(integer) 1

5，判斷key中的值是否存在
127.0.0.1:6379> hexists user name
(integer) 1
127.0.0.1:6379> hexists user1 age
(integer) 0

6，查看所有hash
127.0.0.1:6379> hkeys user

2) "age"
3) "from"
127.0.0.1:6379> hkeys user1
