解压

bash 复制代码
tar -zxvf docker-27.1.0.tgz

将docker二进制文件复制到/usr/bin/

bash 复制代码
cp docker/* /usr/bin/

添加服务文件

bash 复制代码
vim /usr/local/lib/systemd/system/docker.service
bash 复制代码

更改镜像存储目录:

bash 复制代码
sudo vim /etc/docker/daemon.json
bash 复制代码
{
  "data-root": "/mnt/docker"
}

启动验证

bash 复制代码
groupadd docker	#添加docker组,否则docker.socket启动会报错
systemctl start containerd.service && systemctl enable containerd.service
systemctl start docker.socket && systemctl enable docker.socket
systemctl start docker.service && systemctl enable docker.service
docker info		#输出结果正常代表安装成功

下载docker-compose离线安装包

https://github.com/docker/compose/releases/tag/v2.29.3

安装

bash 复制代码
mv docker-compose-linux-x86_64 /usr/bin/
mv /usr/bin/docker-compose-linux-x86_64 /usr/bin/docker-compose
chmod +x /usr/bin/docker-compose
