Docker installation and configuration steps for Redis image

Preface

This tutorial demonstrates how to install the Redis image, create a Redis container, and map ports to mount data volumes and configuration data.

environment

• CentOS 7
• Docker 20.10.10

Install

Pull the image

docker pull redis

View Mirror

docker images

Create and start the MySQL container

Create data directories and configuration files

Create a configuration folder

mkdir -p /mydata/redis/conf

Create a configuration file

touch /mydata/redis/conf/redis.conf

Reminder to avoid pitfalls

Create the redis.conf configuration file in advance. Because when the local /mydata/redis/conf/redis.conf is mounted to /etc/redis/redis.conf , the last redis.conf in the path is not regarded as a file, but as a directory. Therefore, if we want to mount the configuration file redis.conf on the local machine into the Docker container, we need to create the configuration file in advance.

Create and start the 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

Parameter Description

• -p 3306:3306 : Map the container's port 6379 to the host's port 6379
• --name redis : Define 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 and start with the redis image according to the following configuration file /etc/redis/redis.conf

Setting up Redis persistent storage

By default, redis data is stored in memory. After restart, the data is lost. After setting persistent storage, the data will still be in memory after restart.

echo "appendonly yes" >> /mydata/redis/conf/redis.conf
