本文介绍在内网环境下如果通过网络代理映射来完成docekr的安装，首先在能上网的windows机器上安装squid,并启动，本实例中windows机器IP为 192.168.192.101 ,squid服务端口为3130(默认3128)
1、登录进入redhat 7.2
2、依次执行如下语句
1 proxy=192.168.192.101:3130 2 echo "proxy=http://${proxy}" >>/etc/yum.conf 3 echo "http_proxy=${proxy}" >>/etc/profile 4 echo "export http_proxy" >>/etc/profile 5 source /etc/profile #设置完成之后就能上网 6 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 7 sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo 8 yum clean all 9 yum list 10 yum -y install docker 11 groupadd docker 12 useradd -d /home/docker -m -g docker docker 13 # passwd #设置密码 14 systemctl daemon-reexec 15 systemctl start docker 16 #如果启动这一步出错 vi /etc/sysconfig/docker OPTIONS='--selinux-enabled=false 设置成false 17 18 #设置docker代理，使得其可以获取到镜像 19 mkdir -p /etc/systemd/system/docker.service.d 20 echo "[Service]">/etc/systemd/system/docker.service.d/http-proxy.conf 21 echo "Environment="HTTP_PROXY=http://${proxy}/" "HTTPS_PROXY=https://${proxy}/"" >>/etc/systemd/system/docker.service.d/http-proxy.conf 22 systemctl daemon-reload 23 systemctl restart docker
至此docker则安装完成。
