systemctl daemon-reload
systemctl enable docker
systemctl start docker3、验证
systemctl status docker4、迁移
根据实际情况看磁盘空间是否足够，足够可以不迁移
systemctl stop docker
# 创建docker新的目录，根据实际情况修改
mkdir -p /app/data/docker
# 安装迁移工具
yum install rsync -y
# 备份
cd /var/lib
mv docker docker.bak
# 修改数据存储目录
cat > /etc/docker/daemon.json <<EOF
{"data-root":"/app/data/docker/docker"}
EOF
# 启动docker
systemctl daemon-reload
systemctl restart docker
#验证
docker info
