This chapter is the last of the five ways of ordered collection of Redis Sorted Set.

First we use redis-cli to enter the redis

[root@web1 ~] # redis-cli 127.0.0.1 purl 6379 >

1 > zadd

Method: zadd key source1 [key sourceN...]

Description: add one or more ordered collection member elements, update the member's score value if it exists, and insert this idiom to ensure that the member is in the correct location, create a new key if the key does not exist, and then perform the zadd operation

127.0.0.1 zadd zkey1 1 Sunshine\\ first member score 1 (integer) 1127.0.0.1 withscores1 6379 > zrange zkey1 0-1 withscores1) "Sunshine" 2) "1" 127.0.1 withscores1 6379 > integer 3 Sunshine\\ member score 3 (integer) 0127.0.0.1 withscores 6379 > zrange zkey1 0-1 withscores\\ member score becomes 3 Member elements unchanged 1) "Sunshine" 2) "3"

2 > zcard
