一、环境
因某些环境，不能联外网，所以使用docker yum源方法行不通，于是打算离线安装
环境：contos7.3(内核需为3.10+)
cat /etc/redhat-release # CentOS Linux release 7.3.1611 (Core)
二、安装步骤
1）setup
cd /usr/local/resource/docker tar -xzvf docker-18.06.3-ce.tar mv /usr/local/resource/docker/docker/* /usr/bin/ # 将二进制文件移动到bin下
2）systemd docker.service
vim /etc/systemd/system/docker.service
然后将以下内容粘贴进去：
[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
授予执行权限：
chmod +x /etc/systemd/system/docker.service
然后：
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
测试是否成功：
systemctl status docker # 查看Docker状态 docker -v # 查看Docker版本
