1.從官方下載Docker安裝包並上傳至虛擬機
https://download.docker.com/linux/static/stable/x86_64/
2.解壓安裝包
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服務
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docker
chmod +x /etc/systemd/system/docker.service systemctl daemon-reload 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
Tips:
①忽略證書配置
ExecStart=/usr/bin/dockerd --insecure-registry Docker倉庫IP:Docker端口號
②啟動容器報錯：
/usr/bin/docker-current: Error response from daemon: shim error: docker-runc not installed on system.
解決：
ln -s /usr/libexec/docker/docker-runc-current /usr/bin/docker-runc
