Docker安装官方Redis镜像并启用密码认证
参考：docker官方redis文档
1.有特殊版本需求的可以查看redis镜像tag版本
3.2.11, 3.2, 3 (3.2/Dockerfile)
3.2.11-32bit, 3.2-32bit, 3-32bit (3.2/32bit/Dockerfile)
3.2.11-alpine, 3.2-alpine, 3-alpine (3.2/alpine/Dockerfile)
4.0.9, 4.0, 4, latest (4.0/Dockerfile)
4.0.9-32bit, 4.0-32bit, 4-32bit, 32bit (4.0/32bit/Dockerfile)
4.0.9-alpine, 4.0-alpine, 4-alpine, alpine (4.0/alpine/Dockerfile)
2.选择最新版latest
docker pull redis:latest
[root@localhost~]# docker pull redis:latest
latest: Pulling from library/redis
4d0d76e05f3c: Pull complete
cfbf30a55ec9: Pull complete
82648e31640d: Pull complete
fb7ace35d550: Pull complete
497bf119bebf: Pull complete
89340f6074da: Pull complete
Digest: sha256:166788713c58c2db31c41de82bbe133560304c16c70e53a53ca3cfcf35467d8a
Status: Downloaded newer image for redis:latest
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"
-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
[root@localhost~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a126ec987cfe redis:latest "docker-entrypoint.s…" 4 minutes ago Up 4 minutes 0.0.0.0:6379->6379/tcp redis-test
3645da72ece6 portainer/portainer "/portainer" 7 days ago Up 7 days 0.0.0.0:9000->9000/tcp sharp_lovelace

a273504f9646 mysql:5.6.38 "docker-entrypoint.s…" 8 weeks ago Up 5 days 0.0.0.0:3306->3306/tcp mysql5.6.38
redis容器的id是 a126ec987cfe
5.查看进程
ps -ef|grep redis
[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'
[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
# 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
