OpenVPN is a popular open-source virtual private network (VPN) software that allows users to securely connect to remote networks over the internet、Here's an overview of how you can set up OpenVPN on a VPS:

1、Choose your VPS provider and plan.
2、Install a Linux distribution on your VPS, such as Ubuntu or CentOS.
3、Update your system packages:

sudo apt-get update && sudo apt-get upgrade -y For Debian-based systems
sudo yum update For Red Hat-based systems

4、Install necessary dependencies:

sudo apt-get install build-essential libssl-dev libffi-dev python-dev python-pip git -y For Debian-based systems
sudo yum install epel-release gcc openssl-devel python-devel python-pip git -y For Red Hat-based systems

5、Install Python pip if not already installed:

sudo apt-get install python-pip -y For Debian-based systems
sudo yum install python-pip For Red Hat-based systems

6、Install OpenVPN:

sudo pip install openvpn

7、Create a new directory for your OpenVPN configuration files:

mkdir /etc/openvpn/easy-rsa
cd /etc/openvpn/easy-rsa

8、Initialize EasyRSA:

./easyrsa init-pki

9、Generate root CA certificate:

./easyrsa batch create-ca-cert ca.crt

10、Generate server certificates:

./easyrsa gen-dh
./easyrsa build-server-full server ca-key=ca.key dh=dh.pem

11、Generate client certificates:

./easyrsa gen-crl
./easyrsa build-client-full client ca-key=ca.key dh=dh.pem

12、Copy the generated certificates to your VPS:

cp pki/ca.crt /etc/openvpn/
cp pki/issued/server.crt /etc/openvpn/
cp pki/private/server.key /etc/openvpn/
cp pki/dh.pem /etc/openvpn/
cp pki/crl.pem /etc/openvpn/

13、Configure OpenVPN server:
Edit `/etc/openvpn/server.conf` with the following content:

port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push redirect-gateway def1
push dhcp-option DNS 8.8.8.8
keepalive 10 120
tls-auth ta.key 0
tls-cipher AES-256-GCM-SHA384
cipher AES-256-CBC
auth SHA256
verb 1

14、Generate a Diffie-Hellman file:

openssl dhparam -out dh.pem 2048

15、Create a pre-shared key file (`ta.key`):

echo -n your-pre-shared-key ta.key
chmod 600 ta.key

16、Start the OpenVPN service:

sudo systemctl start openvpn@server
sudo systemctl enable openvpn@server

17、Test the connection from another machine using OpenVPN client configuration.

Remember to replace placeholders like `your-pre-shared-key` with actual values according to your needs.

This setup provides a basic OpenVPN server on your VPS、You may need to adjust configurations based on specific requirements or security considerations.
