2.选择最新版latest
docker pull redis:latest
1
[root@localhost~]# docker pull redis:latest
latest: Pulling from library/redis

cfbf30a55ec9: Pull complete

3.启动容器并带密码
docker run --name redis-test -p 6379:6379 -d --restart=always redis:latest redis-server --appendonly yes --requirepass "your passwd"
1
-p 6379:6379 :将容器内端口映射到宿主机端口(右边映射到左边) 
redis-server –appendonly yes : 在容器执行redis-server启动命令，并打开redis持久化配置 
requirepass “your passwd” :设置认证密码 
–restart=always : 随docker启动而启动

4.查看容器
docker ps
1
[root@localhost~]# docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                                          NAMES

redis容器的id是 a126ec987cfe

5.查看进程
ps -ef|grep redis
1
[root@localhost~]# ps -ef|grep redis
polkitd  26547 26535  0 14:58 ?        00:00:00 redis-server *:6379
root     26610 26432  0 15:05 pts/0    00:00:00 grep --color=auto redis

6.进入容器执行redis客户端
docker exec -it a126ec987cfe redis-cli -a 'your passwd'
1
[root@localhost~]# docker exec -it a126ec987cfe redis-cli -h 127.0.0.1 -p 6379 -a 'your passwd'
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> info
# Server
redis_version:4.0.9
redis_git_sha1:00000000
redis_git_dirty:0
redis_build_id:d3ebfc7feabc1290
redis_mode:standalone
os:Linux 3.10.0-693.21.1.el7.x86_64 x86_64

-h 127.0.0.1 :默认不加为-h 127.0.0.1 
-p 6379 :默认不加为 -p 6379

或者连接的时候不带密码,如下：
[root@localhost ~]# docker exec -it a126ec987cfe redis-cli
127.0.0.1:6379> ping
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 'your passwd'
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> info
