首先linux机上安装了docker后需要再安装docker compose，安装比较简单，直接拷贝官网教程

For alpine, the following dependency packages are needed: py-pip, python-dev, libffi-dev, openssl-dev, gcc, libc-dev, and make.

sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Apply executable permissions to the binary:

sudo chmod +x /usr/local/bin/docker-compose

Note: If the command docker-compose fails after installation, check your path. You can also create a symbolic link to /usr/bin or any other directory in your path.

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Test the installation:

docker-compose --version

首先创建一个目录用来放配置文件：/usr/local/redis-compose

新建一个redis.conf配置文件，这里端口使用16379

daemonize no
bind 0.0.0.0
appendonly no
port 16379

创建docker-compose.yml文件

version: '3.5'
services:
  redis:
    image: "redis:latest"
    container_name: my_redis
    command: redis-server /etc/redis/redis.conf
    ports:
      - "16379:16379"
    volumes:
      - ./data:/data
      - ./redis.conf:/etc/redis/redis.conf

参数说明：

version：docker-compose版本，这里使用3.5版本

services：一个service就是一个容器实例

image：表示使用哪个镜像，儿里使用远程image

container_name：设定实例名，不指定的话会根据当前路径和文件配置生成一个名字，如这里不指定名称，会是"redis_compose_redis_1"

command：指定运行的命令，这里会使用本地文件redis.conf挂载到容器的/etc/redis/路径下然后用该文件启动

volumes：这里挂载/data路径和redis.conf文件

 

启动容器：

docker-compose up

控制台输出：

启动成功

也可以后台运行

docker-compose up -d

 使用docker-compose logs -f查看日志

使用docker ps命令可以看到该实例

通过redis-cli工具连接该实例：

 

验证成功
