　　webuy-openvpn用户的客户端配置文件路径：/root/webuy-openvpn.ovpn

　　将此文件导入到openvpn中，连接即可。

　　

3.配置使用账号密码验证

3.1创建脚本:vim /etc/openvpn/checkpsw.sh

#!/bin/sh
###########################################################
# checkpsw.sh (C) 2004 Mathias Sundman <mathias@openvpn.se>
#
# This script will authenticate OpenVPN 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/openvpn/psw-file"
LOG_FILE="/etc/openvpn/openvpn-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

　

3.2添加权限

　　chmod 755 /etc/openvpn/checkpsw.sh
　　

3.3添加账号密码

　　echo 'username1 password1' >> /etc/openvpn/psw-file

3.4修改server.conf
