Centos6.5部署open***帐号密码方式登陆

server端（路由模式）：

一.网络设置

1.开启服务器端路由转发功能

# vi /etc/sysctl.conf

net.ipv4.ip_forward = 1

# sysctl -p

2.设置nat转发:

注：保证×××地址池可路由出外网

# iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERAD

3.时间同步：

# ntpdate asia.pool.ntp.org

二.安装依赖库

# yum install -y openssl openssl-devel lzo lzo-devel pam pam-devel automake pkgconfig

三.安装open***:

#yum install open***

这里我把个人配置贴出来

[root@localhost /etc/open***]$ cat /etc/open***/server.conf
local 0.0.0.0
port 1194
proto tcp
dev tun
ca /etc/open***/easy-rsa-release-2.x/easy-rsa/2.0/keys/ca.crt

verb 3
client-cert-not-required #不使用客户端证书，使用密码进行验证
username-as-common-name #使用认证用户名，不使用证书
script-security 3
auth-user-pass-verify /etc/open***/checkpsw.sh via-env #指定路径，容许登录的用户名及密码

建立检查帐号密码脚本

vim checkpsw.sh

#!/bin/sh
###########################################################
# checkpsw.sh (C) 2004 Mathias Sundman <mathias@open***.se>
#
# This script will authenticate Open××× users against
# a plain text file. The passfile should simply contain
# one row per user with the username first followed by
# one or more space(s) or tab(s) and then the password.

PASSFILE="/etc/open***/psw-file"
LOG_FILE="/var/log/open***-password.log"
TIME_STAMP=`date "+%Y-%m-%d %T"`

###########################################################

if [ ! -r "${PASSFILE}" ]; then
  echo "${TIME_STAMP}: Could not open password file \"${PASSFILE}\" for reading." >> ${LOG_FILE}
  exit 1
fi

CORRECT_PASSWORD=`awk '!/^;/&&!/^#/&&$1=="'${username}'"{print $2;exit}' ${PASSFILE}`

if [ "${CORRECT_PASSWORD}" = "" ]; then
  echo "${TIME_STAMP}: User does not exist: username=\"${username}\", password=\"${password}\"." >> ${LOG_FILE}
  exit 1
fi

if [ "${password}" = "${CORRECT_PASSWORD}" ]; then
  echo "${TIME_STAMP}: Successful authentication: username=\"${username}\"." >> ${LOG_FILE}
  exit 0
fi

echo "${TIME_STAMP}: Incorrect password: username=\"${username}\", password=\"${password}\"." >> ${LOG_FILE}
exit 1

四.下载easy-rsa:

easy-rsa-release-2.x.zip  网上找到资源，其余的有时候我没有试验成功。

unzip easy-rsa-release-2.x.zip -d /etc/open***

cd /etc/open***/easy-rsa-release-2.x
cp easy-rsa ../

cd 2.0/

编辑 vars

[root@localhost /etc/open***]$ grep -v "^#" easy-rsa-release-2.x/easy-rsa/2.0/vars| grep -v "^$"
export EASY_RSA="`pwd`"
export OPENSSL="openssl"
export PKCS11TOOL="pkcs11-tool"
export GREP="grep"
export KEY_CONFIG=`$EASY_RSA/whichopensslcnf $EASY_RSA`
export KEY_DIR="$EASY_RSA/keys"
echo NOTE: If you run ./clean-all, I will be doing a rm -rf on $KEY_DIR
export PKCS11_MODULE_PATH="dummy"
export PKCS11_PIN="dummy"
export KEY_SIZE=2048
export CA_EXPIRE=3650
export KEY_EXPIRE=3650
export KEY_COUNTRY="US"
export KEY_PROVINCE="California"
export KEY_CITY="BJ"
export KEY_ORG="Fort-Funston"
export KEY_EMAIL="dachenc@test.com"
export KEY_OU="MyOrganizationalUnit"
export KEY_NAME="EasyRSA"

保存推迟后给予x权限

chmod +x vars

./vars

./clean-all       #清除文件        

./build-ca server     #生成服务端

./build-dh

以上生成文件时均可以一路回车过去

生成的文件在/etc/open***/easy-rsa-release-2.x/easy-rsa/2.0/keys文件夹中

将ca.crt拷贝到本地

chkconfig open*** on

/etc/init.d/open*** restart

client配置：

https://open***.net/index.php/open-source/downloads.html

以上路径下载客户端 Windows版本

安装完毕后将路径中sample-config的client.o***拷贝到config文件夹中

编辑config文件夹中的client.o***

client
dev tun
proto tcp
remote 公网地址 公网端口
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
#cert user1.crt
#key user1.key
comp-lzo
verb 3
auth-user-pass

编写密码文件：

vi psw-file

client1 123456

chmod 777 psw-file

chown nobody.nobody psw-file

从新链接客户端 输入用户名密码便可登陆
