本文介紹在內網環境下如果通過網絡代理映射來完成docekr的安裝，首先在能上網的windows機器上安裝squid,並啟動，本實例中windows機器IP為 192.168.192.101 ,squid服務端口為3128

1、登錄進入redhat 7.2

2、依次執行如下語句

proxy=192.168.192.101:3128
echo "proxy=http://${proxy}" >>/etc/yum.conf
echo "http_proxy=${proxy}" >>/etc/profile
echo "export http_proxy" >>/etc/profile
source 
 
/etc/profile  #設置完成之後就能上網
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
sed -i  ‘s/$releasever/7/g‘ /etc/yum.repos.d/CentOS-Base.repo
yum clean all
yum list
yum -y install docker
groupadd docker
useradd -d /home/docker -m -g docker docker
# passwd #設置密碼 
systemctl daemon
 
-reexec 
systemctl start docker
#如果啟動這一步出錯 vi /etc/sysconfig/docker OPTIONS=‘--selinux-enabled=false 設置成false

至此docker則安裝完成。
