Linux下离线安装Docker最新版本

一、基础环境
1、操作系统：CentOS 7.3
2、Docker版本：18.06.1 官方下载地址（打不开可能需要梯子）
3、百度云Docker 18.06.1地址：https://pan.baidu.com/s/1YdN9z72QutPkHBfLq06H1A 密码：dvvh
4、官方参考文档：https://docs.docker.com/install/linux/docker-ce/binaries/#install-static-binaries

二、Docker安装

1、下载

wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.1-ce.tgz

2、解压

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

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

chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker

systemctl daemon-reload                 #重新加载配置文件
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
