wget http://download.redis.io/redis-stable.tar.gz tar zxvf redis-stable.tar.gz cd redis-stable.tar.gz make make install
redis-server
redis-cli shutdown
方法一
redis-server /path/to/redis.conf redis-server /path/to/redis.conf --loglevel warning //设置日志级别
方法二
redis-cli
redis > CONFIG SET loglevel warning
> select 1
(1)添加数据和查找数据,通过set/get命令添加和获取数据
127.0.0.1:6379> select 1 OK 127.0.0.1:6379[1]> set bar 1 OK 127.0.0.1:6379[1]> get bar "1" 127.0.0.1:6379[1]> get aaa (nil)
(2)判断一个键是否存在,exists命令可以判断key是否存在,存在返回1,不存在返回0
127.0.0.1:6379[1]> exists bar (integer) 1 127.0.0.1:6379[1]> exists aaa (integer) 0
(3)删除数据,del命令删除key,返回值为成功删除key的个数
127.0.0.1:6379[1]> del aaa (integer) 0 127.0.0.1:6379[1]> del bar (integer) 1
(4)获取value的类型
127.0.0.1:6379[1]> set bar 1 OK 127.0.0.1:6379[1]> type bar string
(5)自增和自减,incr 、decr以及incrby和decrby实现整数的加减
127.0.0.1:6379[1]> INCR ab (integer) 1 127.0.0.1:6379[1]> INCR ab (integer) 2 127.0.0.1:6379[1]> INCRBY ab 2 (integer) 4 127.0.0.1:6379[1]> DECR ab (integer) 3 127.0.0.1:6379[1]> DECRBY ab 2 (integer) 1
(6)增加指定浮点数,incrbyfloat可以指定自增的浮点数
127.0.0.1:6379[1]> INCRBYFLOAT ab 1.1 "2.1"
(7)向尾部追加,append命令可以向字符尾部追加内容
127.0.0.1:6379[1]> set key hello OK 127.0.0.1:6379[1]> append key world (integer) 10 127.0.0.1:6379[1]> get key "helloworld"
(8)获取字符串长度,strlen获取value的长度
127.0.0.1:6379[1]> STRLEN key (integer) 10
(9)批量设置和获取,通过mset和mget命令可以批量执行设置和获取
127.0.0.1:6379[1]> mset key1 va1 key2 va2 OK 127.0.0.1:6379[1]> mget key1 key2 1) "va1" 2) "va2"
(10)位操作
getbit key offset
setbit key offset
bitcount key [start] [end]
bitop operation destkey key [key ...]
{ "id":1, "name":"test" }
(1)存储方法,可以通过hset和hget来设置和获取数据
127.0.0.1:6379[1]> hset user id 1 (integer) 1 127.0.0.1:6379[1]> hset user name test (integer) 1 127.0.0.1:6379[1]> hget user id "1" 127.0.0.1:6379[1]> hget user name "test"
(2)判断字段是否存在,hexists命令,返回1存在,返回0不存在
127.0.0.1:6379[1]> hexists user id (integer) 1 127.0.0.1:6379[1]> hexists user age (integer) 0
(3)使用hsetnx(hset if not exists)如果不存在赋值
127.0.0.1:6379[1]> hsetnx user age 111 (integer) 1 127.0.0.1:6379[1]> hget user age "111"
(4)增加数字
127.0.0.1:6379[1]> hincrby user score 60 (integer) 60 127.0.0.1:6379[1]> hget user score "60"
(5)删除字段
127.0.0.1:6379[1]> hdel user score (integer) 1 127.0.0.1:6379[1]> hget user score (nil)
键 字段 字段值 post:id field value
127.0.0.1:6379[1]> incr userid (integer) 1 127.0.0.1:6379[1]> hset user:1 name test (integer) 1 127.0.0.1:6379[1]> hset user:1 score 90 (integer) 1 127.0.0.1:6379[1]> incr userid (integer) 2 127.0.0.1:6379[1]> hset user:2 name test2 (integer) 1 127.0.0.1:6379[1]> hset user:2 score 99 (integer) 1
添加了两条数据,id为1的名字为test分数为90,而id为2的名字为test2分数为90.
127.0.0.1:6379[1]> hmget user:1 name score 1) "test" 2) "90"
127.0.0.1:6379[1]> hgetall user:2 1) "name" 2) "test2" 3) "score" 4) "99"
127.0.0.1:6379[1]> hkeys user:1 1) "name" 2) "score" 127.0.0.1:6379[1]> hvals user:1 1) "test" 2) "90"
127.0.0.1:6379[1]> hlen user:1 (integer) 2
需要注意的是,散列类型无法获取所有存在的键值,也就是id,如果删除了中间某个id的话,只可以使用exist命令来判断key是否存在。
列表的基本操作命令都是以l开头的。
127.0.0.1:6379> lpush user test (integer) 1 127.0.0.1:6379> rpush user test1 (integer) 2 127.0.0.1:6379> lpop user "test" 127.0.0.1:6379> rpop user "test1" 127.0.0.1:6379>
127.0.0.1:6379> llen user (integer) 0 127.0.0.1:6379> lpush user test (integer) 1 127.0.0.1:6379> llen user (integer) 1
127.0.0.1:6379> lrange user 0 3 1) "test" 2) "test1" 3) "test2" 4) "test3" 127.0.0.1:6379> lrange user 0 2 1) "test" 2) "test1" 3) "test2"
lrem key count value
@count 为删除个数,大于0的话从左边开始,小于0的话从右边开始
@value 要删除的值
我们可以把数据的id存储在列表中,当某一行数据被删除时候,只需要删除为该value为key即可,而查询数据的时候,需要先从列表中读取所有的id,再从散列表中读取数据。
127.0.0.1:6379> lrange user 0 -1 1) "test" 2) "test1" 3) "test2" 4) "test3" 127.0.0.1:6379> linsert user before test1 test0 (integer) 5 127.0.0.1:6379> linsert user after test1 test1.5 (integer) 6 127.0.0.1:6379> lrange user 0 -1 1) "test" 2) "test0" 3) "test1" 4) "test1.5" 5) "test2" 6) "test3"
rdroplpush source destination
从source列表的右侧弹出一个数据,添加到destination列表的左侧
127.0.0.1:6379> sadd key 1 (integer) 1 127.0.0.1:6379> sadd key 2 (integer) 1 127.0.0.1:6379> sadd key 2 (integer) 0 127.0.0.1:6379> smembers key 1) "1" 2) "2" 127.0.0.1:6379> srem key 2 (integer) 1 127.0.0.1:6379> smembers key 1) "1"

srandmember key [count] 127.0.0.1:6379> srandmember key 3 1) "4" 2) "2" 3) "3"
(1)zadd添加元素,并设置分数score
127.0.0.1:6379> zadd students 60 xiaoming (integer) 1 127.0.0.1:6379> zadd students 80 daxiong (integer) 1
127.0.0.1:6379> zscore students xiaoming "60"
