通过命令docker search redis命令查找redis镜像，在docker hub上寻找需要按章的版本。

[root@ecs-7bc6-0001 redis]# docker search redis

# 下载镜像 #

选择现在redis5.0.5

[root@ecs-7bc6-0001 redis]# docker pull redis:5.0.5

下载完成后查看镜像

[root@ecs-7bc6-0001 redis]# docker images redis
    REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
    redis               5.0.5               598a6f110d01        7 days ago          118MB

# 创建配置 #

创建安装目录，并在目录中创建conf配置目录和data数据目录，目录结构为

redis

--conf

--redis.conf

--data

在配置目录下创建redis配置，根据需要自定义配置，默认配置参考[Redis官网默认配置][Redis]，且docker容器运行redis，不需要将redis配置为daemonize运行，即daemonize no，且需要将logfile配置到有权限的位置。

# 创建启动容器 #

[root@ecs-7bc6-0001 redis]# docker run -itd --name redis-master -p 6380:6379 -v $PWD/data:/data -v $PWD/conf:/usr/local/etc/redis/ redis:5.0.5 redis-server /usr/local/etc/redis/redis.conf
    09e7b55bcacbca51546a27c94bfc42aba630eaacf861979e0a424d2d66072311

其中各个部分的意义为：

docker run，创建并运行容器

\-i，开启容器的标准输入STDIN

\-t，为容器开启伪终端tty

\-d，容器后台运行

\--name redis-master，容器名称为redis-master,

\-p 6380:6379，开放容器的6379端口，并映射到宿主机的6380端口

\-v $PWD/data:/data，安装目录下的data目录挂载到容器的/data目录

\-v $PWD/conf:/usr/local/etc/redis，安装目录下的conf目录挂载到容器的/usr/local/etc/redis目录

redis:5.0.5，镜像名称

redis-server /usr/local/etc/redis/redis.conf，redis启动命令

容器启动之后，查看容器

[root@ecs-7bc6-0001 redis]# docker ps
    CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
    09e7b55bcacb        redis:5.0.5         "docker-entrypoint.s…"   14 minutes ago      Up 14 minutes       0.0.0.0:6380->6379/tcp              redis-master

# 测试 #

进入容器redis客户端测试

[root@ecs-7bc6-0001 redis]# docker exec -it 09e7b55bcacb redis-cli -a redis
    Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
    127.0.0.1:6379> keys *
    (empty list or set)
    127.0.0.1:6379> set 1 1
    OK
    127.0.0.1:6379> get 1
    "1"
    127.0.0.1:6379> del 1
    (integer) 1
    127.0.0.1:6379>

其中09e7b55bcacb为容器id，-a redis指定redis客户端登录密码，取决于自定义配置文件，没有密码则不要-a参数。
