Linux下離線安裝Docker

一、基礎環境

1、操作系統：CentOS 7.3

2、Docker版本：18.06.1 官方下載地址（打不開可能很慢）

3、百度雲Docker 18.06.1地址：https://pan.baidu.com/s/1YdN9z72QutPkHBfLq06H1A 密碼：dvvh

4、官方參考文檔：https://docs.docker.com/install/linux/docker-ce/binaries/#install-static-binaries

二、Docker安裝

1、解壓

tar -xvf docker-18.06.1-ce.tgz

2、將解壓出來的docker文件內容移動到 /usr/bin/ 目錄下

mv docker/* /usr/bin/

3、將docker註冊為service

vim /etc/systemd/system/docker.service

將下列配置加到docker.service中並保存

[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、啟動

chmod +x /etc/systemd/system/docker.service #添加文件許可權並啟動docker

systemctl daemon-reload #重載unit配置文件

systemctl start docker #啟動Docker

systemctl enable docker.service #設置開機自啟

5、驗證

systemctl status docker #查看Docker狀態

docker -v #查看Docker版本
