environment

installation
pull images from the nearest region
docker pull redis
view the image
docker images
Create and start MySQL container
Create data directories and profiles
Create Configuration Folder
mkdir -p /mydata/redis/conf
create a profile
The requested URL/conf/redis/was not found on this server.
Create the redis.conf configuration file in advance, because when you mount the local/mydata/redis/conf/redis.conf to/etc/redis/redis.conf, the last redis.conf in the path will not be regarded as a file, but as a directory. Therefore, if we want to mount the local configuration file redis.conf to Docker container, we need to create the configuration file in advance.
#######################################
Complete the steps above to create a data directory and configuration file ~
#######################################
Create and start MySQL container command sudo docker run -p 6379:6379 --name redis \-v /mydata/redis/data:/data \-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf \-d redis redis-server /etc/redis/redis.conf
-p 3306:3306: Map port 6379 of container to port 6379 of host
--name redis: defines the container name as redis
-v /mydata/redis/data:/data: Mount the Redis data folder to the host
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf: Mount the Redis configuration folder to the host
-d redis redis-server /etc/redis/redis.conf: Run in the background, start with redis image according to the configuration file/etc/redis/redis.conf later
View running containers docker ps
