- 下載 Docker
https://download.docker.com/linux/static/stable/x86_64/ - 解壓壓縮文件
tar -zxvf docker-19.03.8.tgz
- 將解壓好的 Docker 文件復(fù)制到 /usr/bin 目錄下
cp docker/* /usr/bin/
- 在 /etc/systemd/system/ 目錄下新增 docker.service 文件勾效，將 docker 注冊(cè)為服務(wù)，內(nèi)容如下

此處的--insecure-registry=127.0.0.1（此處改成你私服ip）設(shè)置是針對(duì)有搭建了自己私服Harbor時(shí)允許docker進(jìn)行不安全的訪問叛甫，否則訪問將會(huì)被拒絕葵第。
- 啟動(dòng) docker
- 為 docker.service 文件添加執(zhí)行權(quán)限
chmod +x /etc/systemd/system/docker.service
- 重新加載配置文件
systemctl daemon-reload
- 啟動(dòng)
systemctl start docker
- 設(shè)置開機(jī)啟動(dòng)
systemctl enable docker.service
- 查看 docker 服務(wù)狀態(tài)
systemctl status docker
