docker离线安装部署 linux_docker官方中文文档

大家好，又见面了，我是你们的朋友全栈君。

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(打不开可能很慢)

4、官方参考文档：

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

mv 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
