The most detailed Docker installation of Redis in history (including illustrations of each step) practical + redis password reset related

Refer to the original link: https://blog.csdn.net/weixin_45821811/article/details/116211724

1. Docker searches for redis images

• Command: docker search <image name>

 docker search redis

You can see that there are many redis images. Since there is no specified version here, the latest version is downloaded by default. redis latest.

2. Docker pulls the image

• Command: :docker pull <image name>:<version number>

docker pull redis

3. Docker mounting configuration file

The next step is to mount the redis configuration file and start the redis container in the configuration file. (Mounting: Associating the host's files with the internal directory of the container and binding them to each other. Modifying the files in the host will also modify the internal files of the container) 1)
Mount the redis configuration file

2) Mount the persistence file of redis (for data persistence).
My configuration file is placed in
the redis.conf file location under liunx: /home/redis/myredis/redis.conf
The redis data file location under liunx: /home/redis/myredis/data The
location can be chosen by yourself.

The mkdir -p /home/redis/myredis command directly creates the /home/redis/myredis folder if it does not exist.

I uploaded myredis.conf manually. (The file is at the end of the article, and the standard file of redis.conf can also be found on the redis official website)

4. Start the redis container

docker run --restart=always --log-opt max-size=100m --log-opt max-file=2 -p 6379:6379 --name myredis -v /home/redis/myredis/myredis.conf:/etc/redis/redis.conf -v /home/redis/myredis/data:/data -d redis redis-server /etc/redis/redis.conf  --appendonly yes  --requirepass 000415

1. –restart=always Always start at boot
2. –log is for logs
3. -p 6379: 6379 mounts port 6379 (the bold one is the container port, : in front is the host port)
4. –name Give this container a name
5. -v data volume mounting
   ————/home/redis/myredis/myredis.conf:/etc/redis/redis.conf Here is where
   myredis.conf under the liunx path and redis.conf under redis are mounted together. .
   –———— /home/redis/myredis/data:/data This is the same as above
6. -d redis means starting redis in the background
7. redis-server /etc/redis/redis.conf
   starts redis with the configuration file, loads the conf file in the container, and finally finds the mounted directory /etc/redis/redis.conf,
   which is /home/redis/ under liunx myredis/myredis.conf
8. –appendonly yes turns on redis persistence
9. –requirepass 000415 Set the password (if you are
   connecting through the internal docker container, you can set it or not. But if you want to open it to the outside world, you must set it. I have been screwed. You can read this article "Alibaba Cloud Server" Poisoning 'Kirito666' experience")
10. success interface
    

5. Test

1. Check the startup status through the docker ps command

docker ps -a |grep myredis # 通过docker ps指令查看启动状态，是否成功.

2. View container running logs

docker logs --since 30m <容器名>

Here --since 30m is to view the log status of this container within 30 minutes.

docker logs --since 30m myredis

3. Connect inside the container for testing
and enter the container

Command: docker exec -it <container name> /bin/bash

The redis-cli that follows here directly enters the command above.

docker exec -it myredis redis-cli

After entering, I directly enter the view command:
there may be an enterable or inaccessible status


error indicating that there is no permission verification. (Because a password is set.)
Verify password:

config get requirepass

7. Docker deletes Redis

After teaching you how to install it, we also need to learn how to uninstall it, otherwise we will not be able to become skilled workers (manual dog head)
7.1 Delete the redis container

• View all running containers:

docker ps -a

• `Stop running Redis

docker stop myredis # myredis 是我启动redis 命名的别

• Delete the redis container:

docker rm myredis

7.2. Delete the Redis image.
After deleting the container, we start to delete the redis image.

• View all mirror commands:

docker images

• Delete the image command docker rmi <container id>

docker rmi 739b59b96069 # 这是我镜像redis id

You can see that the Redis image has been deleted.

1. Docker sets redis password

Method 1: Create a redis container and set a password

docker run -itd --name redis-6379 -p 6379:6379 redis --requirepass 123456

Note: --name (启动容器的名称) -p 映射端口:redis启动端口 redis --requirepass 启动密码
Method 2: Create a password or change the password for existing redis:

#1.进入redis的容器
docker exec -it 容器ID bash

#2.进入redis目录
cd /usr/local/bin

#3.运行命令：
redis-cli

#4.查看现有的redis密码：
config get requirepass

#5.设置redis密码
config set requirepass 密码

This is because redis has set a password, and we need to use the password for verification before operating the redis client. Otherwise, we do not have the authority to operate the redis cache database.

auth 密码

Clear redis password

#将密码置为空字符串即可
config set requirepass ""

***Clear redis password methodconfig set requirepass ""
