1、准备了一台干净的Centos6.5 x64操作系统

#关闭selinux

sed-i'/^SELINUX=/c\SELINUX=disabled'/etc/selinux/config

's/^mirrorlist=https/mirrorlist=http/'/etc/yum.repos.d/epel.repo

2、安装及配置OpenVPN和easy-rsa

yum-yinstallopenvpneasy-rsa

cp -rf /usr/share/easy-rsa/2.0/* /etc/openvpn/easy-rsa/

vim /etc/openvpn/easy-rsa/vars //默认配置不变

[root@localhost ~]# cat /etc/openvpn/easy-rsa/vars | grep -v "#"| 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="CA"

export KEY_CITY="SanFrancisco"

export KEY_ORG="Fort-Funston"

export KEY_EMAIL="me@myhost.mydomain"

export KEY_OU="MyOrganizationalUnit"

export KEY_NAME="EasyRSA"
