OpenVPN服务器端安装和配置 1、安装lzo #tar -zxvf lzo-2.03.tar.gz #cd lzo-2.03 # ./configure --prefix=/usr/local/lzo #make #Make install 2、安装openvpn tar -zxvf openvpn-2.0.9.tar.gz cd openvpn-2.0.9 ./configure --prefix=/usr/local/openvpn --with-lzo-headers=/usr/local/lzo/include --with-lzo-lib=/usr/local/lzo/lib -- with-ssl-headers=/usr/include/openssl --with-ssl-lib=/usr/lib make make install 3、生成证书和Key #cd easy-rsa/ #vi vars export D=`pwd` export KEY_CONFIG=$D/openssl.cnf export KEY_DIR=$D/keys echo NOTE: when you run ./clean-all, I will be doing a rm -rf on $KEY_DIR export KEY_SIZE=1024 export KEY_COUNTRY=CN export KEY_PROVINCE=BJ export KEY_CITY=BJ export KEY_ORG="OpenVPN-TEST" export KEY_EMAIL=wjpheart@126.com #chmod a+x vars [root@localhost easy-rsa]# ./vars NOTE: when you run ./clean-all, I will be doing a rm -rf on /home/weijunping/openvpn-2.0.9/easy-rsa/keys [root@localhost easy-rsa]# ./clean-all you must define KEY_DIR [root@localhost easy-rsa]# export D=`pwd` [root@localhost easy-rsa]# export KEY_CONFIG=$D/openssl.cnf [root@localhost easy-rsa]# export KEY_DIR=$D/keys [root@localhost easy-rsa]# export KEY_SIZE=1024 [root@localhost easy-rsa]# export KEY_COUNTRY=CN [root@localhost easy-rsa]# export KEY_PROVINCE=BJ [root@localhost easy-rsa]# export KEY_CITY=BJ [root@localhost easy-rsa]# export KEY_ORG="OpenVPN-TEST" [root@localhost easy-rsa]# export KEY_EMAIL=wjpheart@126.com [root@localhost easy-rsa]# ./clean-all [root@localhost easy-rsa]# ./build-ca Generating a 1024 bit RSA private key ....++++++ ........++++++ writing new private key to 'ca.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request.
