ovpn file it’s time to use the certificate: ovpn file configuration for use with OpenVPN: To get started using the VPN, we need to create a. Each of these copied files is necessary to use the VPN: Systemctl -f enable start starting and enable the service, we want to configure the client, copy the “ca” certificate, and copy the “client” key. Once you’ve completed your configuration and forwarding rules, it’s time to enable the OpenVPN service and start it up: Iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE
We want to add some forwarding rules before enabling our VPN service: When complete, we want to configure the routing parts of CentOS 7 for use with the VPN installation: Now we’re going to generate our client certificate, replacing the “client” with the username you choose: Take the generated key, copy it, and place the copy in your OpenVPN folder:Ĭp dh2048.pem ca.crt server.crt server.key /etc/openvpn
Make sure to do this on a fresh install, since you will lose all your certificates:Īfter cleaning up, we’re going to generate keys making sure to match our KEY_NAME value:
#Install openvpn access server centos install#
Then you can load the vars file to automate the setup process:īefore proceeding, we want to use a fresh install to clean up a bit. It’s time to start generating keys and certificates. # which will be placed in the certificate.Ĭp /etc/openvpn/easy-rsa/openssl-1.0.0.cnf /etc/openvpn/easy-rsa/openssl.cnf # These are the default values for fields When you’ve finished copying the keys and script, you can edit the vars file to make changes to the default value: Then copy the key and the script:Ĭp -rf /usr/share/easy-rsa/2.0/* /etc/openvpn/easy-rsa This step is optional, but if you want to push all traffic through the VPN, you will want to uncomment the following line:Īfter you’ve edited the configuration file, create a folder to store the key. Now it’s time to edit the server configuration file: Once OpenVPN and EasyRSA are installed, you can copy the example configuration:Ĭp /usr/share/doc/openvpn-*/sample/sample-config-files/nf /etc/openvpn When complete, it’s time to install OpenVPN and EasyRSA (a small key management package for use with OpenVPN) for generating RSA keys: The first step during this installation is to make sure your server node is up-to-date and then reboot, processing any updates if needed:Īfter your system reboots, you can install the EPEL (Extra Packages for Enterprise Linux) repository: As mentioned above, if you are using a domain or sub-domain for this setup, you may want to have that available before walking through the steps to install OpenVPN. Once you’ve chosen your cloud, dedicated, or virtual private server node, verified your CentOS 7 installation, and have root access available, you’re ready to begin. If you’re choosing to use a domain or sub-domain, you may want to set this up before setting up OpenVPN. When you’ve chosen a node, it will need to have an up-to-date version of CentOS 7 running.ĬentOS 7 is a popular Linux-style operating system and you can learn more about the CentOS Project on the project website.Īdditionally, you may choose to use a domain or sub-domain later in this guide. To get started installing OpenVPN, you will need a node running on a cloud server, dedicated server, or virtual private server your operational needs or personal preference can be the deciding factor. Additionally, OpenVPN has been enhanced and modified for use across different router firmware implementations.
