1.从官方下载Docker安装包并上传至虚拟机
https://download.docker.com/linux/static/stable/x86_64/
2.解压安装包
tar -xvf docker-18.06.1-ce.tgz
3.将解压出来的docker文件内容移动到 /usr/bin/ 目录下
cp docker/* /usr/bin/
4.将docker注册为service服务
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.启动docker
chmod +x /etc/systemd/system/docker.service systemctl daemon-reload systemctl start docker #启动Docker systemctl enable docker.service #设置开机自启
6.验证
systemctl status docker #查看Docker状态 docker -v #查看Docker版本
Tips:
①忽略证书配置
ExecStart=/usr/bin/dockerd --insecure-registry Docker仓库IP:Docker端口号
②启动容器报错：
/usr/bin/docker-current: Error response from daemon: shim error: docker-runc not installed on system.
解决：
ln -s /usr/libexec/docker/docker-runc-current /usr/bin/docker-runc
