并执行快速安装&脚本

./openvpn_install_crack.sh 
#!/bin/bash

echo "   ___         _    ___  ___ ____   "
echo "  / __|___ _ _| |_ / _ \/ __|__  |  "
echo " | (__/ -_) ' \  _| (_) \__ \ / /   "
echo "  \___\___|_||_\__|\___/|___//_/    "
echo " OpenVPN Access Server With Unlimited License"

yum install net-tools -y
rpm -ivh openvpn-as-2.5.2-CentOSrelease.x86_64.rpm
echo "=========================SetPassword=============================="

echo "=========================DONE=============================="
rm -rf /usr/local/openvpn_as/lib/python2.7/site-packages/pyovpn-2.0-py2.7.egg
chmod 755 ./pyovpn-2.0-py2.7.egg
\cp -rf ./pyovpn-2.0-py2.7.egg /usr/local/openvpn_as/lib/python2.7/site-packages/
cd /usr/local/openvpn_as/bin
sed -i "s/from pyovpn.util.gcp/#from pyovpn.util.gcp/g" /usr/local/openvpn_as/bin/_ovpn-init
./ovpn-init


echo "=========================Status=============================="
