各个版本Docker地址：https://download.docker.com/linux/static/stable/x86_64/

一、下载安装包

#1.进入软件下载目录，下载Docker-20.10.9安装包
[root@staging ~]# cd /data/software/
[root@staging software]# wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.9.tgz

#2.查看下载的安装包
[root@staging software]# ll -h
total 17G
-rw-r--r--  1 root root  61M Oct 25 16:19 docker-20.10.9.tgz

二、解压安装包

#1.解压安装包到/data2目录下
[root@staging software]# tar xf docker-20.10.9.tgz  -C /data2/
[root@staging software]# cd /data2

#2.重命名docker目录
[root@staging data2]# mv docker docker-20.10.9

三、做软连接

[root@staging data2]# ln -s docker-20.10.9 docker
[root@staging data2]# ll
total 14515840
lrwxrwxrwx  1 root root          14 Oct 27 11:27 docker -> docker-20.10.9
drwxrwxr-x  2 root root         169 Oct  5 00:08 docker-20.10.9

四、配置环境变量

[root@staging docker]# vi /etc/profile.d/docker.sh 
export PATH=/data2/docker:$PATH

[root@staging docker]# source /etc/profile.d/docker.sh 

五、配置system启动

[root@staging docker]# vi /usr/lib/systemd/system/docker_new.service

六、启动dockerd服务进程

[root@staging docker]# systemctl daemon-reload

[root@staging docker]# systemctl  enable  --now docker_new.service
