通过mysql数据库来验证账号密码，方便以后用来记录用户当前在线离线状态的判断

#!/bin/bash HOST="localhost" DB="openvpn" DBUSER="openvpn" DBPASS="123456" DBTABLE='openvpn_user' user=`echo ${username}|sed "s#'/|;/|=/|%##g"` MYSQL="/usr/bin/mysql -h${HOST} -u${DBUSER} -p${DBPASS} " result=`$MYSQL << EOF |tail -n +2 select count(1) from ${DB}.${DBTABLE} WHERE is_enabled='1' AND is_vpn='1' AND password=md5('${password}') AND username='${user}'; EOF` if [ $result -eq 1 ];then exit 0; else exit 1; fi

data-ciphers BF-CBC 2.4版本默认的是'BF-CBC'但是2.5的版本默认不是这个了，需要手动配置，具体配置参考下面的

cipher AES-256-CBC
