docker安裝与docker-compose安装

yum -y update
yum install -y yum-utils  device-mapper-persistent-data   lvm2
yum-config-manager  --add-repo  http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce docker-ce-cli containerd.io
systemctl start docker
systemctl enable docker
curl -L  http://bisheng-public.oss-cn-zhangjiakou.aliyuncs.com/resource/docker/docker-compose  -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

docker目录迁移

sudo systemctl stop docker.socket
sudo systemctl stop docker.service
mkdir -p /data/docker/lib
rsync -avzP /var/lib/docker /data/docker/lib/
cd /etc/docker/

暂停： 这里需要手动编辑 /etc/docker/daemon.json 文件将以下文件补充进入daemon.json

{
    "data-root": "/data/docker/lib/docker",
}

补充完成后，继续执行以下命令

systemctl daemon-reload
sudo systemctl start docker.socket
sudo systemctl start docker.service
sudo systemctl enable docker.service
