**
Linux下离线安装docker，docker-compose
**
1、下载
百度云Docker 18.06.1地址：链接：https://pan.baidu.com/s/1a5UH8cY3kRdo0TWyQj_tPA
提取码：kvzf
2、将下载的安装包上传至/home下，以下操作在/home这执行命令即可（此处以/home为例，实际位置基本随意）
一、docker安装
1、解压
tar -xvf docker-18.06.1-ce.tgz
2、将解压出来的docker文件内容移动到 /usr/bin/ 目录下
cp docker/* /usr/bin/
3、将docker注册为service
```bash
vi /etc/systemd/system/docker.service
将下列配置加到docker.service中并保存
[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
4、启动
chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker
systemctl daemon-reload #重载unit配置文件
systemctl start docker #启动Docker
systemctl enable docker.service #设置开机自启
5、验证
systemctl status docker #查看Docker状态，如下说明成功运行
docker -v #查看docker版本
二、docker-compose安装
mv docker-compose-Linux-x86_64 docker-compose #重命名
cp docker-compose /usr/local/bin/ #移动位置
docker-compose -v #查看docker-compose版本，有显示的话说明成功，如下
