docker pull redis

# 创建容器
docker run -itd --name redis-test -p 6379:6379 redis

# 进入容器
docker exec -it redis-test /bin/bash

# 开启客户端
redis-cli
# 启动远程客户端
# redis-cli -h host -p port -a password

# 测试
ping
# PONG

# 默认有 16 个数据库，默认用第 0 个
select 1

# 显示当前库下所有的键
keys *

# 清空当前 DB
flushdb

# 删除所有数据库，危
flushall

Issues

清空的时候抛错，我估计是我的 docker redis 没有配置本地存储信息，并不能进行本地化相关操作，创建的时候挂在到本地可能就行了

flushdb 
(error) MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

猜测失败，是配置问题，关闭了快找功能，导致保存失败，可以在客户端使用 config set stop-writes-on-bgsave-error no 解决问题
