Docker使用(六) — Docker离线安装部署

1、目的

在可以连接互联网的情况下，可以在线安装Docker《Linux下Docker安装部署》，如果遇到内网服务器就没有办法进行在线安装，那么需要使用离线安装的方法。

2、下载安装包

创建工作文件夹：

mkdir /opt/docker

docker安装包下载地址：https://download.docker.com/linux/static/stable/x86_64/
进入下载地址，下载相应的版本，比如20.10.9，将下载好的文件放到/opt/docker目录下

3、创建系统配置文件

创建文件：

vim /opt/docker/docker.service

内容如下：

[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、创建安装脚本

vim /opt/docker/install.sh

内容如下：

#!/bin/sh
echo '解压tar包...'
tar -xvf $1
echo '将docker目录移到/usr/bin目录下...'
cp docker/* /usr/bin/
echo '将docker.service 移到/etc/systemd/system/ 目录...'
cp docker.service /etc/systemd/system/
echo '添加文件权限...'
chmod +x /etc/systemd/system/docker.service
echo '重新加载配置文件...'
systemctl daemon-reload
echo '启动docker...'
systemctl start docker
echo '设置开机自启...'
systemctl enable docker.service
echo 'docker安装成功...'
docker -v

5、创建卸载脚本

vim /opt/docker/uninstall.sh

内容如下：

#!/bin/sh
echo '删除docker.service...'
rm -f /etc/systemd/system/docker.service
echo '删除docker文件...'
rm -rf /usr/bin/docker*
echo '重新加载配置文件'
systemctl daemon-reload
echo '卸载成功...'

6、安装

1、安装目录结构如下：

2、执行安装脚本：

sh install.sh docker-20.10.9.tgz

7、配置国内源

编辑daemon.josn

vim /etc/docker/daemon.json

配置国内源地址

{
 "registry-mirrors" : [
   "https://mirror.ccs.tencentyun.com",
   "http://registry.docker-cn.com",
   "http://docker.mirrors.ustc.edu.cn",
   "http://hub-mirror.c.163.com"
 ],
 "insecure-registries" : [
   "registry.docker-cn.com",
   "docker.mirrors.ustc.edu.cn"
 ],
 "debug" : true,
 "experimental" : true
}

重启docker

systemctl restart docker.service
