问题描述：
内网离线环境下，安装docker.二进制来的还是快点，或者内网搭建yum的epel仓库！
环境：
centos7.x
docker-18.9.0 x86_64 static //二进制
解决方法：
1、download:
https://download.docker.com/linux/static/stable/x86_64/
2、kernel ack
[root@lab-210 ~]# uname -r //kerner3.10.+ centois7.x 内核都是3.10+，此举只是为了验证
3.10.0-862.el7.x86_64
3、setup
docker-18.06.1-ce.tgz
tar zxf docker-18.06.1-ce.tgz && mv docker/* /usr/bin/ && rm -rf docker*.tgz //解压切移动binary到 /usr/bin
注意：如果移动到别的目录有点问题，systemctl脚本启动不起来，具体原因还在寻找中
4、systemd docker.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 -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock 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、grant privilege
chmod +x /etc/systemd/system/docker.service
systemctl daemon-reload //重载systemd下 xxx.service文件
systemctl start docker //启动Docker
systemctl enable docker.service //设置开机自启
6、testing docker
systemctl status docker //查看Docker状态
docker -v //查看Docker版本
附录centos7.x安装脚本 install.sh
