1.1 总结

指令	描述
redis-cli	使用命令行工具
auth xxxxxx	登录redis，验证密码 xxxxxx
sadd key membe [membe...] smembers key	创建set列表   127.0.0.1:6379> sadd set duck pig cow sheep sheep sheep pig (integer) 4 查看set列表 127.0.0.1:6379> smembers set 1) "duck" 2) "cow" 3) "sheep" 4) "pig"
scard key	查看列表长度    127.0.0.1:6379> scard set (integer) 4
sismember key membe	是否存在在set中    127.0.0.1:6379> sismember set pig (integer) 1 127.0.0.1:6379> sismember set chicken (integer) 0
srem key member [member ...]	删除    127.0.0.1:6379> srem set duck (integer) 1 127.0.0.1:6379> SMEMBERS set 1) "cow" 2) "sheep" 3) "pig"
spop key [count]	随机出栈    127.0.0.1:6379> spop set "cow" 127.0.0.1:6379> smembers Set 1) "sheep" 2) "pig" 127.0.0.1:6379> spop set 2 1) "pig" 2) "sheep" 127.0.0.1:6379> smembers set (empty list or set) 127.0.0.1:6379>
srandmember key count	从set中随机获取count个数    127.0.0.1:6379> sadd set1 1 2 3 4 5 6 7 8 9 10 (integer) 10 127.0.0.1:6379> smembers set1 1) "1" 2) "2" 3) "3" 4) "4" 5) "5" 6) "6" 7) "7" 8) "8" 9) "9" 10) "10" 127.0.0.1:6379> srandmember set1 3 1) '6" 2) '8" 3) "2" 127.0.0.1:6379>
smove source destination member	set间数据剪切 （member：值）    127.0.0.1:6379> sadd set1 1 2 3 (integer) 3 127.0.0.1:6379> sadd set2 4 5 6 (integer) 3 l27.0.0.l:6379> smove setl set2 3 (integer) 1 127.0.0.l:6379> smembers set1 1) "1" 2) "2" 127.0.0.l:6379> smembers set2 1) "3" 2) "4" 3) "5" 4) "6"
set  差集，交集，并集
sdiff key [key ...]	差集 = set1 - set2 重合部分    127.0.0.1:6379> sdiff set1 set2 1) "2" 2) "4" 3) "6" 4) "8"
sinter key [key ...]	交集 ：两个集合相同的部分    127.0.0.1:6379> sinter set1 set2 1) "1" 2) "3" 3) "5" 4) "7" 5) "9
sunion key [key ...]	并集 = set1 + set2 127.0.0.1:6379> sunion set1 set2 1) "1" 2) "2" 3) "3" 4) "4" 5) "5 6) "6" 7) "7" 8) "8" 9) "9" 10) "10 11) "11" 12) "13" 13) "15" 127.0.0.1:6379>
