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3130(默认3128)

1、登录进入redhat 7.2

2、依次执行如下语句

proxy=192.168.192.101:3130
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。
