wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.2.tgz

或：

手动下载地址并上传：https://download.docker.com/linux/static/stable/x86_64/docker-20.10.2.tgz

2. 解压后并复制到/usr/bin目录下

tar zxvf docker-20.10.2.tgz 

cp  docker/* /usr/bin/  

3. 添加docker.service文件

LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s 

[Install]
WantedBy=multi-user.target 

 chmod +x /etc/systemd/system/docker.service  

4. 添加 docker.socket 文件

vi /lib/systemd/system/docker.socket
