Docker 搭建Redis 踩坑

在使用 Docker 搭建 Redis 的过程中，产生了**刻板效应**，导致的搭建时间的延长，做个小记录，提醒自己！

创建属于自己的 Redis

新建一个 Redis 的 Dockerfile ， Redis 的版本没有选择默认为 lastest

FROM redis
    COPY redis.conf /usr/local/etc/redis/redis.conf
    CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]

在同路径下，新增全新的 **redis.conf** 文件，方便自定义

[root@localhost redis]# ls
    Dockerfile  redis.conf

通过 **Dockerfile** 构建 Redis 基础镜像

[root@localhost redis]# docker build -t myredis .
    Sending build context to Docker daemon  73.22kB
    Step 1/3 : FROM redis
     ---> a55fbf438dfd
    Step 2/3 : COPY redis.conf /usr/local/etc/redis/redis.conf
     ---> a3b1763aeeb2
    Step 3/3 : CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]
     ---> Running in 00dd0a1ca908
    Removing intermediate container 00dd0a1ca908
     ---> 86f3dbf1cb71
    Successfully built 86f3dbf1cb71
    Successfully tagged myredis:latest
    [root@localhost redis]# docker images
    REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
    myredis             latest              86f3dbf1cb71        6 seconds ago       95.1MB
    redis               latest              a55fbf438dfd        5 weeks ago         95MB

通过 Docker 启动 Redis

[root@localhost redis]# docker run -d -p 6379:6379 -v /home/docker/redis/redis.conf:/usr/local/etc/redis/redis.conf --name myredis redis redis-server /usr/local/etc/redis/redis.conf

通过 telent 192.168.124.15 6379 访问

访问失败

我突然想到 redis.conf 默认是只让本机访问的 注释掉了 bind 127.0.0.1

#bind 127.0.0.1

再次调用 **telent 192.168.124.15 6379** , 报错提醒

Redis 的报错信息基本 告诉我们如何解决这个问题，再次打开 redis.conf

# The server only accepts connections from clients connecting from the
    # IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain
    # sockets.
    #
    # By default protected mode is enabled. You should disable it only if
    # you are sure you want clients from other hosts to connect to Redis
    # even if no authentication is configured, nor a specific set of interfaces
    # are explicitly listed using the "bind" directive.
    protected-mode no

将 protected-mode yes 改为 no 即可 连接成功
