OpenVPN的点对点简单实现

准备条件

server端为本地的一台虚拟机搭建的centos系统；

client端为本地Windows系统

服务端部署

1.准备源下载软件包

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm
yum clean all
yum makecache

# 安装依赖软件包
yum install -y lzo lzo-devel openssl openssl-devel pam pam-devel
yum install -y pkcs11-helper pkcs11-helper-devel rpm-build

# 安装OpenVPN
yum install openvpn -y

2.下载并配置EasyRSA

#下载EasyRSA 3.0.7
cd /opt/
wget https://github.com/OpenVPN/easy-rsa/releases/download/v3.0.7/EasyRSA-3.0.7.tgz
tar xf EasyRSA-3.0.7.tgz
mv EasyRSA-3.0.7 easyRSA-3.0.7
cp -r easyRSA-3.0.7/ /etc/openvpn/easy-rsa3
cp /etc/openvpn/easy-rsa3/vars.example /etc/openvpn/easy-rsa3/vars

3.创建相关证书和密钥

cd /etc/openvpn/easy-rsa3/
#初始化目录
./easyrsa init-pki

#创建根证书
#nopass 参数表示不加密；也可以不加此参数，那就需要输入密码短语
./ea
