Docker安装官方Redis镜像并启用密码认证实践笔记

参考：docker官方redis文档 <https://hub.docker.com/_/redis/>

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 (4.0/32
bit/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/redis4d0d76e05f3c: Pull complete cfbf30a55ec9: Pull
complete82648e31640d: Pull complete fb7ace35d550: Pull complete 497bf119bebf:
Pull complete89340f6074da: Pull complete Digest: sha256:166788713
c58c2db31c41de82bbe133560304c16c70e53a53ca3cfcf35467d8aStatus: 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
agoUp 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_lovelace118ba79de20a hwdsl2/ipsec-vpn-server "/opt/src/run.sh" 12 days ago
Up 12 days 0.0.0.0:500->500/udp, 0.0.0.0:4500->4500/udp l2tp-vpn-server 848
fdba6de60 kylemanna/openvpn"ovpn_run" 12 days ago Up 12 days 1194/udp, 0.0.0.0:
1194->1194/tcp openvpn a273504f9646 mysql:5.6.38 "docker-entrypoint.s…" 8 weeks
agoUp 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:Linux3.10.0-693.21.1.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 arch_bits:64
