本例以 ce版 演示

1、下载安装包

https://download.docker.com/linux/static/stable/x86_64/

我下载的是：docker-18.06.3-ce.tgz（截止发稿日最新版本）

2、上传文件

SSH上传或者挂载U盘到主机目录

3、解压

tar -zxvf docker-18.06.3-ce.tgz

4、移动 Docker

cp docker/* /usr/bin/

5、注册服务

vim /etc/systemd/system/docker.service

记录下面信息，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
