sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine

2 Setup repository
sudo yum install -y yum-utils

sudo systemctl start docker

5 Configure image acceleration
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://chqac97z.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

start-up docker

systemctl start docker

2, install redis

1 stay docker hub Search for redis Mirror image
docker search redis

2 Pull redis Mirror to local
docker pull redis:6.0.10

3 Modify the configuration that needs to be customized (docker-redis There is no configuration file by default ,
Mount the mapping after the host is established )
Create and modify /usr/local/redis/redis.conf
bind 0.0.0.0 Open remote permissions
appendonly yes Turn on aof Persistence

4 start-up redis Service run container , Start the container
docker run --name redis -v /usr/local/redis/data:/data -v /usr/local/redis/redis.conf:/usr/local/etc/redis/redis.conf -p 6379:6379 -d redis:6.0.10 redis-server /usr/local/etc/redis/redis.conf

explain ： -v /usr/local/redis/data:/data # Hang the data directory locally to ensure data security
-v /root/redis/redis.conf:/usr/local/etc/redis/redis.conf # Hang the configuration file locally for easy modification

5 Go straight in redis client .
docker exec -it redis redis-cli

6 Local remote connection redis

7 You need to open the firewall on Tencent cloud to pass

8 Set up redis The account and password of the connection
