假设001机器有公网可以上网，002-010这9台服务器和001在同一个局域网下，可以ping通但是没有公网，其他的机器可以用001作为跳转机器，将001设置成代理机器，所有的网络请求通过001机器进行访问。

yum软件镜像代理

1.在可以上网的服务器上安装Squid：

sudo yum install squid

配置Squid：
打开Squid配置文件进行编辑：

sudo vim /etc/squid/squid.conf

找到并编辑以下行（确保取消注释并设置合适的值）：

http_access allow all
http_port 3128

启动Squid服务：

sudo systemctl start squid

确保Squid在系统启动时自动启动：

sudo systemctl enable squid

不能联网的服务器上

vim /etc/profile

export http_proxy=http://公网ip:3128
export https_proxy=https://公网ip:3128

生效配置文件

source /etc/profile

测试

更换yum镜像源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

vim /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
