3.open***设置使用账号密码登录（4）01-15

4.open***隧道web管理端搭建使用（5）01-16 5.open***隧道手动搭建流程（2）01-16

1. 写个脚本（脚本是由官网提供）

vim /etc/openvpn/checkpsw.sh 
 
#!/bin/sh
###########################################################
# checkpsw.sh (C) 2004 Mathias Sundman 
#
# 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

2.接下来给脚本执行权限

1	`chmod` `755` `/etc/openvpn/checkpsw.sh`

3.配置用户密码文件

vim /etc/openvpn/psw-file
#前面为用户名，后面为密码。 中间使用空格分开
abclent 123456
abc 123456
test test123

4.设置服务端配置文件

vim /etc/openvpn/server.conf
#在service.conf最后添加
script-security 3
auth-user-pass-verify /etc/openvpn/checkpsw.sh via-env    #指定用户认证脚本
username-as-common-name
verify-client-cert none

5. 设置客户端文件

#主要是注释crt和key路径，以及添加一行auth-user-pass
client
dev tun
proto tcp
remote xxx.xxx.xxx.xxx 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
;cert cyh.crt     #注释
;key cyh.key      #注释
tls-auth ta.key 1
cipher AES-256-CBC
comp-lzo
verb 3
auth-user-pass              #使用用户名密码登录
