一、实验环境

操作系统： CentOS7.x

serverA：192.168.1.108

serverB： 192.168.1.107

二、安装docker

在serverA 

https://download.docker.com/linux/static/edge/x86_64

# wget https://download.docker.com/linux/static/edge/x86_64/docker-18.04.0-ce.tgz

#  tar -zxvf docker-17.04.0-ce.tgz

#  cp ./docker/docker*  /usr/bin/

#  vim /etc/systemd/system/docker.service

三、搭建yum源

在serverA

# mkdir  -p  /var/www/html

# mv *.rpm  /var/www/html

# createrepo  -v  /var/www/html

# docker pull httpd

# docker run -itd  --name  LocalRepositry    -p  80:80 -v /var/www/html/:/usr/local/apache2/htdocs/  httpd:latest

# iptables  -F

访问  http://192.168.1.108

 四、测试局域网yum源

在serverB

# mkdir  /etc/yum.repos.d/backup

# mv  /etc/yum.repos.d/*.repo  /etc/yum.repos.d/backup

# vim  /etc/yum.repos.d/test.repo
