1.安装lzo-2.0.5使openvpn支持压缩功能
tar xf lzo-2.05.tar.gz &&cd lzo-*
./configure
make && make install
cd ..
2.安装openvpn服务
tar xf openvpn-2.2.0.tar.gz &&cd openvpn-*
./configure
make && make install
复制证书生成所需文件
mkdir /etc/openvpn && cp easy-rsa /etc/openvpn -r
3.安装radiusplugin
tar xf radiusplugin_v2.1a_beta1.tar.gz && cd radiusplugin_*
make 将会生成radiusplugin.so 将其cp到/etc/openvpn目录下
cp radiusplugin.cnf /etc/openvpn/conf/
4.生成服务端所需证书
cd /etc/openvpn/easy-rsa/2.0/
vi vars #编辑变量
.vars#source命令使变量生效
./clean-all
./build-ca#ca.crt ---Root CA证书，用于签发Server和Client证书
./build-key-server server #server.crt server.key-创建并签发VPN Server使用的CA
./build-key client1 #client1.crt client1.key #如果客户端需要使用证书方式认证则需要这个东东，创建客户端证书，一个客户端一个证书
./build-key client2
./build-dh#dh1024.pem--生成Diffie-Hellman文件 ,TLS用到
openvpn --genkey --secret keys/ta.key #生成tls auth key
复制证书文件到配置文件目录
mkdir /etc/openvpn/conf && cd keys
cp ca.crt server.crt server.key dh1024.pem ta.key /etc/openvpn/conf/
tar czf clientkey.tgz ca.crt client1.crt client1.key # 如果客户端使用证书方式认证则这里需要这个东东，本文介绍的radius方式不需要。
5.编辑openvpn服务端配置文件
vi /etc/openvpn/conf/server.conf
port 1194
proto udp
dev tap #TAP设备是一块虚拟的以太网卡，TUN设备是一个虚拟的点到点IP链接。
ca /etc/openvpn/conf/ca.crt
cert /etc/openvpn/conf/server.crt
key /etc/openvpn/conf/server.key# This file should be kept secret
dh /etc/openvpn/conf/dh1024.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 10.8.0.1"
push "dhcp-option DNS 208.67.222.222"
push "dhcp-option DNS 208.67.220.220"
client-to-client
keepalive 10 120
tls-auth /etc/openvpn/conf/ta.key 0
comp-lzo
user nobody
group nobody
persist-key
persist-tun
status openvpn-status.log
verb 3
client-to-client #如果让Client之间可以相互看见，去掉本行的注释掉，否则Client之间无法相互访问
;duplicate-cn#是否允许一个User同时登录多次，去掉本行注释后可以使用同一个用户名登录多次
client-cert-not-required #客户端不使用CA证书验证
username-as-common-name #使用客户提供的UserName作为Common Name
;max-clients 1000#最大连接数
plugin /etc/openvpn/radiusplugin.so /etc/openvpn/conf/radiusplugin.cnf #radius插件
script-security 3
编辑radius插件配置文件
vi /etc/openvpn/conf/radiusplugin.cnf
NAS-Identifier=OpenVpn
Service-Type=5
Framed-Protocol=1
NAS-Port-Type=5
NAS-IP-Address=127.0.0.1
OpenVPNConfig=/etc/openvpn/conf/server.conf
subnet=255.255.255.0
overwriteccfiles=true
nonfatalaccounting=false
server
{
# The UDP port for radius accounting.
acctport=1813
# The UDP port for radius authentication.
authport=1812
# The name or ip address of the radius server.
name=127.0.0.1
# How many times should the plugin send the if there is no response?
retry=1
# How long should the plugin wait for a response?
wait=1
# The shared secret.
sharedsecret=testpw
}
启动openvpn
/usr/local/sbin/openvpn--cd /etc/openvpn \
--config /etc/openvpn/conf/server.conf &
配置内核路由转发和iptables

mv /var/www/phpMyadmin* /var/www/phpmyadmin && cd /var/www/phpmyadmin
cp config.sample.inc.php config.inc.php
vi config.inc.php 修改以下

此处的radiusadmin账号是在phpmyadmin里创建的并给予radius库相应操作权限；

启动apache
/etc/init.d/httpd restart
访问http://192.168.0.2/radius
username: administrator

在用户管理里面添加一个账号，即可用这个账号进行认证登陆。

win7需要以管理员身份运行OpenVPN GUI ，使用daloradius里添加的账号密码登陆。
添加ipv6支持：让openvpn客户端支持Ipv6网络，需要将openvpn使用的虚拟网卡与具有ipv6地址的物理网卡进行桥接，让openvpn监听在此桥接的虚拟网卡上，然后通过自动DHCP实现为客户端分配ipv6地址。安装配置网卡桥接：yuminstall bridge-utils编辑bridge-start启动脚本，根据系统网络设备对应编辑。下载radvd：http://www.litech.org/radvd/dist/radvd-1.8.tar.gztarxf radvd-* && cd radvd-*./configure --sysconfdir=/etcmake && make install修改配置文件 vi /etc/radvd.confinterface br0{AdvSendAdvert on;MinRtrAdvInterval 3;MaxRtrAdvInterval 10;AdvDefaultPreference low;prefix 2001:250:1002:40::/64 //客户端IPv6前缀{AdvOnLink on;AdvAutonomous on;AdvRouterAddr on;};};
