Start the Redis cluster

  1. Follow this command to run the primary and secondary redis libraries separately
Sh docker_restart.sh < name > < Port >Copy the code

Docker_restart. sh Contents are as follows

#! /bin/shapplication_name=$1 port=$2 echo "application=${application_name}" echo "port=${port}" echo "container is stoping and removing" containerId=$(docker ps -a | grep -E "${application_name}" | awk '{print $1}') if [ !  -z $containerId ] then docker stop $containerId && docker rm $containerId fi echo "container is running" docker run -it  --name ${application_name} \ -d -p ${port}:${port} redis redis-server --requirepass lindj --port ${port}Copy the code
  1. Enter the container started in the first step
Docker exec it <redis library name > bashCopy the code
  1. Load the configuration
redis-server /usr/local/etc/redis/redis.conf
Copy the code

Repeat steps 2 and 3 until all containers have been executed and the Redis cluster is started.

test

Enter the main library

docker exec -it redis-master bash
#Connect the redisRedis -cli -a lindj -p < port > set name 123Copy the code

Enter from the library

docker exec -it redis-slave1 bash
#Connect the redisRedis -cli -a lindj -p < port > get nameCopy the code
