一、当前Linux为本人定制的操作系统CentOS5.5,自动安装,大约要10分钟,安装完成后将系统更新升级到最新内容，及安装必要的软件包；
1、更新系统内核到最新.
#yum -y update
将系统更新到最新版本,系统更新完成后,如果yum安装时提示错误信息,请执行以下命令修复;
# rpm -import /etc/pki/rpm-gpg/RPM-GPG-KEY-*
2、yum 安装必要的编译环境(安装GCC，GCC++编译环境）
#yum install gcc gcc-c++
3、 安装Apahce, PHP, Mysql, 以及php连接mysql库组件,如果要换行的话请加"\";否则更新不完整；
[root@vpn ~]# yum -y install httpd php mysql mysql-server php-mysql httpd-manual \
mod_ssl mod_perl mod_auth_mysql php-mcrypt php-gd php-xml php-mbstring \
php-ldap php-pear php-xmlrpc mysql-connector-odbc mysql-devel libdbi-dbd-mysql \
libgcrypt libgcrypt-devel openssl openssl-devel pam pam-devel pkgconfig
注意:将以上内容完放在一行执行,将以上的工作完成后就可以接着以下的工作了;
如图:
安装完成后启动相关的服务：
[root@vpn ~]# chkconfig mysqld on
[root@vpn ~]# chkconfig httpd on
[root@vpn ~]# service httpd start
Starting httpd: [ OK ]
[root@vpn ~]# [root@vpn ~]# service mysqld start
Starting MySQL: [ OK ]
4、配置动态域名更新htsprings.3322.org
#yum –y install lynx
安装完成后设定定时更新：
#crontab -e
*/15 * * * * /usr/bin/lynx -mime_header -auth=nansen:8888888 "http://www.3322.org/dyndns/update?system=dyndns&hostname=test.3322.org"
保存一下重启crond服务；以后每隔15分钟更新一次；
[root@openvpn /]# service crond restart
停止 crond： [确定]
启动 crond： [确定]
5、Yum安装rpm-build，安装好后可以制作RPM包；
[root@openvpn /]# yum -y install rpm-build
6、查看openssl是否安装成功;
[root@openvpn openvpn]# rpm -qa |grep openssl
openssl-0.9.8e-12.el5_4.6
openssl-devel-0.9.8e-12.el5_4.6
7、注意：关闭SELinux ，iptables
二、OpenVPN软件及相关软件下载
（A）准备软件
1、建立下载软件目录；
[root@openvpn /]# mkdir -p /home/src/openvpn
[root@openvpn /]# cd /home/src/openvpn/
2、下载openvpn-2.0.9.tar.gz软件，建议不要装2.1.3版本的软件（不支持外部验证）；
# wget http://openvpn.net/release/openvpn-2.0.9.tar.gz
3、安装 lzo
如果你想使用VPN连接的压缩特性，或者你想将OpenVPN安装为一个RPM包，安装LZO Library。
#wget http://www.oberhumer.com/opensource/lzo/download/lzo-2.03.tar.gz
4、下载mysql管理软件phpmyadmin软件
#wget http://nchc.dl.sourceforge.net/p ... 1.11-english.tar.gz
（B）开始安装软件
1、安装lzo软件；
[root@openvpn openvpn]# ls
[root@openvpn openvpn]# tar -zxvf lzo-2.03.tar.gz
[root@openvpn openvpn]# cd lzo-2.03
[root@openvpn openvpn]# ./configure && make &&make install
等待片刻直到完成，注意看有没有出错，一般情况不会有问题；
编辑 /etc/ld.so.conf
[root@openvpn lzo-2.03]# cat >> /etc/ld.so.conf << EOF
/usr/local/lib
EOF
或者使用vi /etc/ld.so.conf
加入下内容：/usr/local/lib
编辑完后运行:
[root@vpn lzo-2.03]#ldconfig
使动态连接库文件生效,接下来编译openvpn
2、安装openvpn软件
[root@openvpn lzo-2.03]# cd /home/src/openvpn
[root@openvpn openvpn]# tar -zxvf openvpn-2.0.9.tar.gz
[root@openvpn openvpn]# cd openvpn-2.0.9
[root@openvpn openvpn-2.0.9]# ./configure && make &&make install
Openvpn默认安装位置是 /usr/local/sbin/openvpn
[root@openvpn openvpn-2.0.9]# whereis openvpn
openvpn: /usr/local/sbin/openvpn
====================================================================================
此部分不必操作，想RPM安装的上面部分LZO不用装；
或者使制作RPM包后安装需要安装 lzo-devle包，可以从rpmfind.net网站上下载，这两个软件我已经下载好了，传到服务器上，过程略；
[root@openvpn openvpn]# rpm -ivh lzo-2.03-2.1.i386.rpm
Preparing... ########################################### [100%]
1:lzo ########################################### [100%]
[root@openvpn openvpn]# rpm -ivh lzo-devel-2.03-2.1.i386.rpm
Preparing... ########################################### [100%]
1:lzo-devel ########################################### [100%]
[root@openvpn openvpn]# rpmbuild -tb openvpn-2.0.9.tar.gz
制作好后，RPM安装文件在/usr/src/redhat/RPMS/i386/
[root@openvpn openvpn]# cp /usr/src/redhat/RPMS/i386/openvpn-2.0.9-1.i386.rpm /home/src/openvpn
安装省略
====================================================================================
三、配置openvpn服务器
1、让VI显示彩色；
[root@vpn openvpn]# rpm -e sendmail --nodeps
[root@vpn conf]# vi /root/.bashrc
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
alias vi='vim' //加入这一行,编辑器使用VIM
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
2、 建立配置环境
[root@openvpn openvpn-2.0.9]# mkdir -p /etc/openvpn/keys
[root@openvpn openvpn-2.0.9]# mkdir -p /etc/openvpn/easy-rsa
[root@openvpn openvpn-2.0.9]# cp easy-rsa/2.0/* /etc/openvpn/easy-rsa/
[root@openvpn openvpn-2.0.9]# cd /etc/openvpn/easy-rsa/
--------------------------------------------------------------------
此目录下以许多程序及脚本, 以下为使用到的程序及脚本说明
vars 脚本, 是用来创建环境变量,设置所需要要的变量的脚本
clean-all 脚本,是创建生成ca证书及密钥文件所需要的文件及目录
build-ca 脚本, 生成ca证书(交互)
build-dh 脚本, 生成Diffie-Hellman文件(交互)
build-key-server 脚本, 生成服务器端密钥(交互)
build-key 脚本, 生成客户端密钥(交互)
pkitool 脚本, 直接使用vars的环境变量设置, 直接生成证书(非交互)
---------------------------------------------------------------------

为了防止DDOS，生成ta.key
[root@openvpn easy-rsa]# /usr/local/sbin/openvpn --genkey --secret keys/ta.key
压缩keys下的所有文件，以方便传到FTP，供客户端下载
[root@openvpn easy-rsa]# tar -cvf client1.tar.gz keys/*
keys/ca.crt
keys/ca.key
keys/client1.crt
keys/client1.csr
keys/client1.key
[root@openvpn easy-rsa]# tar -cvf client1.tar.gz keys/*

keys/ta.key [root@openvpn easy-rsa]#mv client1.tar.gz /var/ftp/pub
将证书复制到ftp公用目录下
[root@openvpn easy-rsa]# cp -rf keys/* /etc/openvpn/keys/
复制keys下的文件到/etc/openvpn/keys下
[root@openvpn easy-rsa]# rm -rf client*
删除以client1开头的文件
3、复制配置文件及脚本；
[root@openvpn openvpn]# cd /home/src/openvpn/openvpn-2.0.9
[root@openvpn openvpn-2.0.9]# cp sample-config-files/server.conf /etc/openvpn/
[root@openvpn openvpn]# vi server.conf

# must set aside an IP range in this subnet
# (start=10.8.0.50 end=10.8.0.100) to allocate

# Configure server mode for ethernet bridging
# using a DHCP-proxy, where clients talk
# to the OpenVPN server-side DHCP server
# to receive their IP address allocation
# and DNS server addresses. You must first use
# your OS's bridging capability to bridge the TAP
# interface with the ethernet NIC interface.
# Note: this mode only works on clients (such as
# Windows), where the client-side TAP adapter is
# bound to a DHCP client.
;server-bridge
# Push routes to the client to allow it
# to reach other private subnets behind
# the server. Remember that these
# private subnets will also need
# to know to route the OpenVPN client
# address pool (10.8.0.0/255.255.255.0)
# back to the OpenVPN server.
;push "route 172.16.0.0 255.255.0.0"
push "route 192.168.6.0 255.255.255.0"
# To assign specific IP addresses to specific
# clients or if a connecting client has a private
# subnet behind it that should also have VPN access,
# use the subdirectory "ccd" for client-specific
# configuration files (see man page for more info).
# EXAMPLE: Suppose the client
# having the certificate common name "Thelonious"
# also has a small subnet behind his connecting
# machine, such as 192.168.40.128/255.255.255.248.
# First, uncomment out these lines:
;client-config-dir ccd
;route 192.168.40.128 255.255.255.248
# Then create a file ccd/Thelonious with this line:
# iroute 192.168.40.128 255.255.255.248
# This will allow Thelonious' private subnet to
# access the VPN. This example will only work
# if you are routing, not bridging, i.e. you are
# using "dev tun" and "server" directives.
# EXAMPLE: Suppose you want to give
# Thelonious a fixed VPN IP address of 10.9.0.1.
# First uncomment out these lines:
;client-config-dir ccd
;route 10.9.0.0 255.255.255.252
# Then add this line to ccd/Thelonious:
# ifconfig-push 10.9.0.1 10.9.0.2
# Suppose that you want to enable different
# firewall access policies for different groups
# of clients. There are two methods:
# (1) Run multiple OpenVPN daemons, one for each
# group, and firewall the TUN/TAP interface
# for each group/daemon appropriately.
# (2) (Advanced) Create a script to dynamically
# modify the firewall in response to access
# from different clients. See man
# page for more info on learn-address script.
;learn-address ./script
# If enabled, this directive will configure
# all clients to redirect their default
# network gateway through the VPN, causing
# all IP traffic such as web browsing and

# (The OpenVPN server machine may need to NAT
# or bridge the TUN/TAP interface to the internet
# in order for this to work properly).
;push "redirect-gateway def1 bypass-dhcp"
;push "redirect-gateway def1"
# Certain Windows-specific network settings
# can be pushed to clients, such as DNS

# Uncomment this directive to allow different
# clients to be able to "see" each other.
# By default, clients will only see the server.
# To force clients to only see the server, you
# will also need to appropriately firewall the

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝4、启动openvpn服务
[root@openvpn]# cp /hoe/src/openvpn/sample-scripts/openvpn.init /etc/init.d/openvpn
[root@openvpn]# vi /etc/init.d/openvpn
修改以下内容到openvpn的安装位置
openvpn_locations="/usr/local/sbin/openvpn"
第119行去掉#
echo 1 > /proc/sys/net/ipv4/ip_forward
加入：
iptables -t nat -A POSTROUTING -s 10.8.0.0/16 -j SNAT --to 192.168.6.0
这样客户端就可以访问服务器所在的网络；
启动Openvpn服务
[root@openvpn keys]# service openvpn restart
正在关闭openvpn： [确定]
正在启动 openvpn： [确定]
[root@openvpn keys]# service vsftpd restart
关闭 vsftpd： [失败]
为 vsftpd 启动 vsftpd： [确定]
5、 客户端配置：Winxp SP3,下载客户端软件并安装,我下载的是2.1.3版
配置文件在安装目录下config目录，可以制样版配置然后修改；
Client.opvn
client
proto udp
dev tun
;auth-user-pass
auth-nocache
resolv-retry infinite
nobind
persist-key
persist-tun
comp-lzo

# 以你客户端ca认证文件及密钥文件目录为准
#####################################################
ca ca.crt
cert client1.crt
key client1.key
tls-auth ta.key 1
#####################################################
从服务器上下载客户端的证书文件
这是我的服务器ftp://192.168.0.20，下载后从服务器上删除它；
打开client1.tar.gz这个包，复制客户端证书到config目录
Ca.key ca.crt client1.key client1.src client1.crt ta.key
点击connect，连接成功！
至此以证书方式验证完成，已测试OK！
三、配置以Php验证用户连接；
之前已经安装好了php mysql httpd等软件，接下来配置相关的内容；
编辑服务器配置文件,当前目录为/etc/openvpn/：
[root@openvpn openvpn]# vi server.conf
加入以下内容并保存：
tmp-dir /tmp
auth-user-pass-verify "php /etc/openvpn/pass.php" via-env
client-cert-not-required
username-as-common-name
[root@openvpn openvpn]# vi pass.php
#!/usr/bin/php -q
<?php
$db_host = "localhost";
$db_user = "root";
