下载得到 docker-27.2.1.tgz 和 docker-compose-linux-x86_64 两个文件。

# 解压 docker
tar -vxzf docker-27.2.1.tgz
# 拷贝到系统 PATH 下
cp -f docker/* /usr/bin/
# 创建 docker plugins 目录，用于放置 docker compose
mkdir -p /usr/lib/docker/cli-plugins
# 拷贝 docker compose 到目录下
mv docker-compose-linux-x86_64 /usr/lib/docker/cli-plugins/docker-compose
# 添加可执行权限
chmod +x /usr/lib/docker/cli-plugins/docker-compose
# 刷新
source ~/.bashrc

创建一个 docker.service 的系统服务，并设置开机自启。

# 创建一个 docker.service
vim /etc/systemd/system/docker.service
