CentOS7下打通调试PC到K8s Pod之间网络的实践过程
以CentOS7服务器为例
1、快速安装包直接解压安装
tar -zxvf openvpn_install.tar.gz
并执行快速安装&脚本
./openvpn_install_crack.sh #!/bin/bash echo " ___ _ ___ ___ ____ " echo " / __|___ _ _| |_ / _ \/ __|__ | " echo " | (__/ -_) ' \ _| (_) \__ \ / / " echo " \___\___|_||_\__|\___/|___//_/ " echo " OpenVPN Access Server With Unlimited License" echo "=========================Install==============================" yum install net-tools -y rpm -ivh openvpn-as-2.5.2-CentOSrelease.x86_64.rpm echo "=========================SetPassword==============================" echo "SETUP AdminUI Login PASSWORD" passwd openvpn echo "=========================DONE==============================" rm -rf /usr/local/openvpn_as/lib/python2.7/site-packages/pyovpn-2.0-py2.7.egg chmod 755 ./pyovpn-2.0-py2.7.egg \cp -rf ./pyovpn-2.0-py2.7.egg /usr/local/openvpn_as/lib/python2.7/site-packages/ cd /usr/local/openvpn_as/bin sed -i "s/from pyovpn.util.gcp/#from pyovpn.util.gcp/g" /usr/local/openvpn_as/bin/_ovpn-init ./ovpn-init echo "=========================Status==============================" systemctl status openvpnas.service chmod 755 /usr/local/openvpn_as/lib/python2.7/site-packages/pyovpn-2.0-py2.7.egg
说明：脚本来自github并做了部分修改
输入DELETE，并输入yes，然后一路回车即可
2、登录AdminUI管理界面
可以看到License已经为1024 devices（说明已经crack成功）
3、根据自身实际场景配置
1）指定可以访问的子网网段
2）关闭Internet traffic be routed through the *PN
3）Do not alter clients' DNS server settings
然后保存配置然后Update Running Server
4、创建用户并配置用户Profile
5、下载客户端，安装后连接
6、连通性测试
看能否访问相应的子网 10.200.0.0/16子网
如图所示，说明访问10.200.0.0/16段的业务OK
