redhat 7.2 内网安装docker

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3128

1、登录进入redhat 7.2

2、依次执行如下语句

 proxy=192.168.192.101:
 echo "proxy=http://${proxy}" >>/etc/yum.conf
 echo "http_proxy=${proxy}" >>/etc/profile
 echo "export http_proxy" >>/etc/profile
 source /etc/profile  #设置完成之后就能上网
 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 #设置密码
 systemctl daemon-reexec
 systemctl start docker
 #如果启动这一步出错 vi /etc/sysconfig/docker OPTIONS='--selinux-enabled=false 设置成false

 #设置docker代理，使得其可以获取到镜像
 mkdir -p /etc/systemd/system/docker.service.d
 echo "[Service]">/etc/systemd/system/docker.service.d/http-proxy.conf
 echo "Environment=\"HTTP_PROXY=http://${proxy}/\" \"HTTPS_PROXY=https://${proxy}/\"" >>/etc/systemd/system/docker.service.d/http-proxy.conf
 systemctl daemon-reload
 systemctl restart docker

至此docker则安装完成。
