一、版本说明：

系统：centos 7

docker：18

redis：6.0.3

二、单机服务搭建

1、下载redis

[root@VM_0_6_centos conf]# docker images
    REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
    redis                       latest              987b78fc9e38        3 weeks ago         104MB

2、新建配置文件redis.conf

[root@VM_0_6_centos standalone]# ls
    conf  data  
    [root@VM_0_6_centos standalone]# pwd
    /opt/redis/standalone
    [root@VM_0_6_centos standalone]# cd conf/
    [root@VM_0_6_centos conf]# ls
    redis.conf

redis.conf

bind 0.0.0.0
    #是否禁止公网访问redis cache 开启条件 没有bind IP  没有设置requirepass访问密码
    protected-mode no
    #是否开启守护模式
    daemonize no
    #aof日志 每次写操作都记录一条日志
    appendonly yes
    #是否开启集群
    cluster-enabled no
    #密码
    requirepass 123456

3、启动命令

docker run -d  -p 6378:6379 --restart always --name redisStandalone -v /opt/redis/standalone/conf/redis.conf:/etc/redis/redis.conf -v /opt/redis/standalone/data:/etc/redis/data redis

4、查看镜像

[root@VM_0_6_centos conf]# docker ps -a
    CONTAINER ID        IMAGE                COMMAND                  CREATED             STATUS                     PORTS                              NAMES
    ba0728d45348        redis                "docker-entrypoint.s…"   7 minutes ago       Up 7 minutes               0.0.0.0:6378->6379/tcp             redisStandalone

5、测试是否成功

[root@VM_0_6_centos conf]# docker exec -it ba0728d45348 /bin/bash
    root@ba0728d45348:/data# redis-cli -p 6379 -c
    127.0.0.1:6379>
    127.0.0.1:6379>
    127.0.0.1:6379> exit
    root@ba0728d45348:/data# exit
    exit
    [root@VM_0_6_centos conf]#

或者使用RedisDesktopManager 连接查看。

6、遇到的问题。

6.1、ERR AUTH <password> called without any password configured for the default user. Are you sure your configuration is correct?

docker重启后，原设置的密码会失效，需要重新设置。（刚发现）

root@ba0728d45348:/data# redis-cli -h localhost
    localhost:6379> auth 123456
    (error) ERR AUTH <password> called without any password configured for the default user. Are you sure your configuration is correct?
    localhost:6379> config get requirepass
    1) "requirepass"
    2) ""
    localhost:6379> config set requirepass 123456
    OK
    localhost:6379> auth 123456
    OK
    localhost:6379>
