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

a、配置yum源
sudo yum install -y yum-utils
sudo yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo
b、使用阿里云yum源,解决国外网速慢的问题
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
1.3、安装Docker
sudo yum install -y docker-ce docker-ce-cli containerd.io #以下是在安装k8s的时候使用 yum install -y docker-ce-20.10.7 docker-ce-cli-20.10.7 containerd.io-1.4.6
1.4、Start Docker.
#启动方式1、
sudo systemctl start docker
#启动方式2、
systemctl enable docker --now
1.5、配置加速
sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"], "exec-opts": ["native.cgroupdriver=systemd"], "log-driver": "json-file", "log-opts": { "max-size": "100m" }, "storage-driver": "overlay2" } EOF sudo systemctl daemon-reload sudo systemctl restart docker
1.6、运行hello word
sudo docker run hello-world
