SpringBoot连接redis

1 docker安装redis(6.2.2)

1.1 下载redis镜像

sudo docker pull redis:6.2.2

1.2 设置配置文件

手动创建redis.conf，并添加如下配置参数。

# 可远程连接
# bind 127.0.0.1
# 解除保护模式
protected-mode no
# 数据持久化
appendonly yes
# 设置密码
requirepass 123456

也可以在网上下载redis配置文件，注意需要修改里面的配置。

wget http://download.redis.io/redis-stable/redis.conf

授权配置文件

chmod 777 redis.conf

1.3 生成容器

sudo docker run -itd \
--name myredis \
-p 6379:6379 \
-v /home/redis/redis.conf:/etc/redis/redis.conf \
-v /home/redis/data:/data \
redis:6.2.2 redis-server /etc/redis/redis.conf

2 简单使用redis

# 进入redis
sudo docker exec -it myredis /bin/bash# 使用redis
# 参数--raw，表示按原生数据显示，可以解决中文显示乱码，按原始格式打印
redis-cli --raw# 输入密码
auth 123456# (1) 键值对
# 创建键值对
set name mason
# 查看键值对
get name# (2) 列表
# 插入列表
RPUSH user "河南大学"
# 查看列表中所有数据
LRANGE users 0 -1# (3) hash
# 插入键值对，key:book, field: title, value: "河南大学发展"
HSET book title "河南大学发展"
# 查看键值对
HGET book title# redis清空所有数据
flushall
