MacBook使用docker方式部署Redis踩坑经历

问题：docker宿主机上SpringBoot项目连接docker中的Redis被拒绝

思路：停止原有进程，删除容器，宿主机写好配置文件后与容器进行映射，镜像第一次启动时使用映射的配置文件进行启动

redis官方配置文件模板下载地址

在redis对应版本的配置文件中修改下面几项：

# 解除本地连接限制
# bind 127.0.0.1
# 默认yes，解除保护模式，不限制为本地访问
protected-mode no
# 默认no，使用docker启动redis无需处理
daemonize no
# 设置密码
requirpass 123456
# 持久化(可选，容器启动命令已经附带该配置项)
appendonly yes

redis镜像启动命令：

docker run --restart=always -p 6379:6379 --name redis -v /Users/defchan/Documents/redis/conf/redis.conf:/etc/redis/redis.conf  -v /Users/defchan/Documents/redis/data:/data -d redis redis-server /etc/redis/redis.conf --appendonly yes

至此，宿主机上的SpringBoot项目成功连接Redis
