一、基礎環境
1、操作系統：CentOS 7.3
2、Docker版本：18.06.1 官方下載地址（打不開可能需要梯子）
3、百度雲Docker 18.06.1地址：https://pan.baidu.com/s/1YdN9z72QutPkHBfLq06H1A 密碼：dvvh
4、官方參考文檔：https://docs.docker.com/install/linux/docker-ce/binaries/#install-static-binaries
二、Docker安裝
1、下載
wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.1-ce.tgz
2、解壓
tar -xvf docker-18.06.1-ce.tgz
3、將解壓出來的docker文件內容移動到 /usr/bin/ 目錄下
cp docker/* /usr/bin/
4、將docker注冊為service
vim /etc/systemd/system/docker.service
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd ExecReload=/bin/kill -s HUP $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel. We recommend using cgroups to do container-local accounting. LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity # Uncomment TasksMax if your systemd version supports it. # Only systemd 226 and above support this version. #TasksMax=infinity TimeoutStartSec=0 # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process # restart the docker process if it exits prematurely Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target
5、啟動
chmod +x /etc/systemd/system/docker.service #添加文件權限並啟動docker systemctl daemon-reload #重新加載配置文件 systemctl start docker #啟動Docker systemctl enable docker.service #設置開機自啟
6、驗證
systemctl status docker #查看Docker狀態 docker -v #查看Docker版本
