下载Redis image

sudo docker pull redis

运行镜像

sudo docker run -itd --name redis-test -p 6379:6379 redis

如果发现有如下重复镜像错误可以先删除镜像

sudo docker rmi 8e712f4f1065

$sudo docker run -itd --name redis-test -p 6379:6379 redisdocker: Error response from daemon: Conflict. The container name "/redis-test" is already in use by container "8e712f4f1065ed8bf01d52766aa412af60c58ac6a82521e2eeb1b4a08ef35a27". You have to remove (or rename) that container to be able to reuse that name.See 'docker run --help'.$sudo docker ps -a -q8e712f4f10653e84ea15aac8$sudo docker rmi 8e712f4f1065

检查镜像版本

sudo docker image inspect redis:latest|grep -i version

$sudo docker image inspect redis:latest|grep -i version                "GOSU_VERSION=1.12",                "REDIS_VERSION=6.2.4",        "DockerVersion": "19.03.12",                "GOSU_VERSION=1.12",                "REDIS_VERSION=6.2.4",

查看redis镜像情况

$ sudo docker ps -aCONTAINER ID   IMAGE                          COMMAND                  CREATED          STATUS                      PORTS     NAMESea506c589d1c   redis                          "docker-entrypoint.s…"   48 seconds ago   Exited (0) 14 seconds ago             redis-test3e84ea15aac8   apache/sharding-proxy:latest   "/bin/sh -c '${LOCAL…"   4 weeks ago      Exited (137) 4 weeks ago              vigorous_golick

运行和停止redis

$ sudo docker ps -aCONTAINER ID   IMAGE                          COMMAND                  CREATED          STATUS                      PORTS     NAMESea506c589d1c   redis                          "docker-entrypoint.s…"   48 seconds ago   Exited (0) 14 seconds ago             redis-test3e84ea15aac8   apache/sharding-proxy:latest   "/bin/sh -c '${LOCAL…"   4 weeks ago      Exited (137) 4 weeks ago              vigorous_golick$ sudo docker start redis-testredis-test$ sudo docker ps -aCONTAINER ID   IMAGE                          COMMAND                  CREATED          STATUS                     PORTS                                       NAMESea506c589d1c   redis                          "docker-entrypoint.s…"   58 seconds ago   Up 2 seconds               0.0.0.0:6379->6379/tcp, :::6379->6379/tcp   redis-test3e84ea15aac8   apache/sharding-proxy:latest   "/bin/sh -c '${LOCAL…"   4 weeks ago      Exited (137) 4 weeks ago                                               vigorous_golick$ sudo docker stop redis-testredis-test

执行redis-cli

sudo docker exec -it redis-test /bin/bash

$sudo docker exec -it redis-test /bin/bashroot@9f70c9122c06:/data# redis-cli

Redis的sorted set操作

zadd key score member 将成员以及该成员的分数

zscore key member 返回指定成员的分数

zcard key 获取集合中成员数量

zrem key member 移除集合汇总指定的成员，可以指定多个成员

zrange key start end withscores 获取集合中脚注为start-end的成员

zrevrange key start stop with scores 按照分数从大到小的顺序返回索引从start到stop之间的所有元素

127.0.0.1:6379> zadd z1 1.0 a(integer) 1127.0.0.1:6379> zadd z1 1.5 b(integer) 1127.0.0.1:6379> zadd z1 2 c(integer) 1127.0.0.1:6379> zcard key(integer) 0127.0.0.1:6379> zcard z1(integer) 3127.0.0.1:6379> zrange z1 a c(error) ERR value is not an integer or out of range127.0.0.1:6379> zrange z1 1.0 2(error) ERR value is not an integer or out of range127.0.0.1:6379> help zrange  ZRANGE key min max [BYSCORE|BYLEX] [REV] [LIMIT offset count] [WITHSCORES]  summary: Return a range of members in a sorted set  since: 1.2.0  group: sorted_set127.0.0.1:6379> zrange z1 1.0 2 withscores(error) ERR value is not an integer or out of range127.0.0.1:6379> zrange z1 1 2 withscores1) "b"2) "1.5"3) "c"4) "2"127.0.0.1:6379> zrange z1 1 21) "b"2) "c"
