这一章是Redis Sorted Set有序集合五种方式的最后一种，

首先我们使用redis-cli进入redis

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

1>zadd

方法：zadd key source1 [key sourceN...]

描述：添加一个或多个有序集合成员元素，如果存在则更新成员的分数值，并插入此成语，确保该成员在正确的位置，如果key不存在则创建一个新的key，然后在执行zadd操作

127.0.0.1:6379> zadd zkey1 1 Sunshine \\第一次成员分数1 (integer) 1 127.0.0.1:6379> zrange zkey1 0 -1 withscores 1) "Sunshine" 2) "1" 127.0.0.1:6379> zadd zkey1 3 Sunshine \\成员分数3 (integer) 0 127.0.0.1:6379> zrange zkey1 0 -1 withscores \\成员分数变成3，成员元素没变 1) "Sunshine" 2) "3"
