WantedBy=multi-user.target 

chmod u+x /usr/lib/systemd/system/docker.service
systemctl daemon-reload
systemctl enable docker
systemctl start docker

3、验证

systemctl status docker

4、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
