Docker Redis ​

shell
docker pull redis:latest
shell
docker run -itd --name local-redis --restart=always -p 6379:6379 redis
  • -p: 指定容器端口映射到主机端口
  • --name: 指定运行容器名

进入运行的 Redis 服务

shell
docker exec -it local-redis /bin/bash

单节点部署Redis操作 ​

  1. 拉取基本配置文件到配置目录

    从github的redis里获取，比如当前最新版本为7.4，则地址为https://github.com/redis/redis/blob/8.0/redis.conf

    拷贝内容，写入/home/docker/redis/config名为redis.conf

  2. 启动 创建数据卷，启动docker

# 创建数据卷
sudo docker volume create redis-data
# 启动docker
sudo docker run -d \
  --privileged \
  --network host \
  --name redis \
  -v /home/docker/redis/config:/etc/redis \
  -v redis-data:/data \
  redis \
  redis-server /etc/redis/redis.conf

  1. 修改配置

    • protected-mode no：可非本host访问

    • requirepass 123456: 开启密码访问

    • appendonly yes：启用AOF持久化

    • aof-use-rdb-preamble yes：开启混合持久化模式（RDB + AOF）

    • bind 0.0.0.0 -::1：使宿主机可以访问

      重启redis

注意 ​

问题1：

WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

解决：sudo vim /etc/sysctl.conf,sudo sysctl -p,sysctl vm.overcommit_memory重启docker的redis

问题2：

启动后docker logs发现报错 Failed to write PID file: Permission denied

解决：使用--privileged启动提升权限
