【Docker】离线安装

离线安装Docker

1、下载docker 离线安装包

​ 下载地址如下：Index of linux/static/stable/x86_64/

2、将下载的包上传至服务器上

我这里下载的是20.10.9

3、解压文件

tar -zxvf docker-20.10.9.tgz

解压后的文件如下所示

4、复制文件

cd docker
cp ./* /usr/bin

5、创建docker.service文件

cd /etc/systemd/system/
touch docker.service

6、编辑docker.service 文件

vim docker.service

注意：将其中的ip地址，改成您的服务器地址，其它参数不用改。

修改完成后的docker.service

7、 添加可执行权限

chmod +x docker.service

8、加载docker.service

systemctl daemon-reload

注意，若修改了docker.service文件，则要重新加载该文件。

9、启动docker

systemctl start docker

10、查看docker

systemctl status docker

11、查看docker版本

docker -v

[root@0001 system]# docker -v
Docker version 20.10.9, build c2ea9bc
