之前介绍过如何在ubuntu安装Redis服务器：https://www.cnblogs.com/zifeiy/p/9062738.html
接下来，我们在Redis上进行一些基本的操作。
所县使用命令：redis-cli登陆Redis命令行。
然后执行下面的指令进行测试与学习：
字符串类型的增删改查
### 增加一个值key为name，value为zifeiy
127.0.0.1:6379> set name 'zifeiy'
OK
### 查询name的值
127.0.0.1:6379> get name
"zifeiy"
### 更新name的值
127.0.0.1:6379> set name 'yiefiz'
OK
### 查询name的值
127.0.0.1:6379> get name
"yiefiz"
### 删除namd的值
127.0.0.1:6379> del name
(integer) 1
### 查询是沟存在name，0表示不存在
127.0.0.1:6379> exists name
(integer) 0
List集合的增删改查
### 添加key为user_list，value为'zifeiy','hello'的list集合
127.0.0.1:6379> lpush user_list 'zifeiy' 'hello'
(integer) 2
### 查询key为user_list的集合
127.0.0.1:6379> lrange user_list 0 -1
1) "hello"
2) "zifeiy"
### 往list底部添加love元素
127.0.0.1:6379> rpush user_list 'hi'
(integer) 3
### 查询key为user_list的集合
127.0.0.1:6379> lrange user_list 0 -1
1) "hello"
2) "zifeiy"
3) "hi"
### 更新index为0的值
127.0.0.1:6379> lset user_list 0 'haha'
OK
### 查询key为user_list的集合
127.0.0.1:6379> lrange user_list 0 -1
1) "haha"
2) "zifeiy"
3) "hi"
### 删除第1个为'wish'的值
127.0.0.1:6379> lrem user_list 0 'haha'
(integer) 1
### 查询key为user_list的集合
127.0.0.1:6379> lrange user_list 0 -1
1) "zifeiy"
2) "hi"
Hash集合的增删改查
127.0.0.1:6379> flushdb
OK
127.0.0.1:6379> hset user_hset "user1" "zifeiy"
(integer) 1
127.0.0.1:6379> hset user_hset "user2" "apple"
(integer) 1
127.0.0.1:6379> hlen user_hset
(integer) 2
127.0.0.1:6379> hkeys user_hset
1) "user1"
2) "user2"
127.0.0.1:6379> hget user_hset "user1"
"zifeiy"
127.0.0.1:6379> hgetall user_hset
1) "user1"
2) "zifeiy"
3) "user2"
4) "apple"
127.0.0.1:6379> hset user_hset "user1" "new_zifeiy"
(integer) 0
127.0.0.1:6379> hset user_hset "user2" "banena"
(integer) 0
127.0.0.1:6379> hgetall user_hset
1) "user1"
2) "new_zifeiy"
3) "user2"
4) "banena"
127.0.0.1:6379> hdel user_hset user1
(integer) 1
127.0.0.1:6379> hgetall user_hset
1) "user2"
2) "banena"
SortedSet集合的增删改查
127.0.0.1:6379> flushdb
OK
127.0.0.1:6379> zadd user_zset 1 "zifeiy"
(integer) 1
127.0.0.1:6379> zadd user_zset 2 "banana"
(integer) 1
127.0.0.1:6379> zadd user_zset 3 "hello"
(integer) 1
127.0.0.1:6379> zrange user_zset 0 -1
1) "zifeiy"
2) "banana"
3) "hello"
127.0.0.1:6379> zrevrange user_zset 0 -1
1) "hello"
2) "banana"
3) "zifeiy"
127.0.0.1:6379> zscore user_zset "zifeiy"
"1"
127.0.0.1:6379> zscore user_zset "hello"
"3"
