Linux下离线安装Docker

Linux下离线安装Docker

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）

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、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

vim /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

docker -v                                                                                     #查看Docker版本
