Step-by-Step OpenVPN Server Installation & Setup
Step 1: Deploying the Server
Choosing an Image
- Use the OpenVPN server image from the official Marketplace (or any pre-configured image) to quickly launch the system.
- This streamlines deployment and reduces setup time.
Receiving Login Credentials
-
After server creation, an instruction manual with login credentials will be available in your personal account.
-
The same details are typically sent to your registered email.
With OpenVPN, you can ensure secure, encrypted communication across your network—easily and reliably!
The user password is also automatically saved on the server in the following file:
/root/.password_credentials
To view its contents, run the following command in the console:
cat /root/.password_credentials
Step 2: Accessing the Web Interface
Open your browser and enter the IP address of your deployed OpenVPN server. For example:
http://11.00.44/
If you receive a security certificate warning, allow the connection—this is normal for self-signed certificates on a test or newly deployed server.
Step 3: Logging In
For the first login, use the credentials provided after deployment.
-
The default username may be:
Administrator
-
The password can be found in the installation instructions or retrieved from the server using:
cat /root/.password_credentials
Once logged in, you'll gain full access to the OpenVPN management panel.
Managing OpenVPN Server
Creating VPN Users
- Open the Admin Panel and navigate to the section for managing users.
- Enter a desired username (e.g., User).
- Click "Create User" to generate a new VPN account. This user will now be able to connect to the OpenVPN server using their credentials.
Downloading Configuration Files
After creating a user, you will have the option to download the .ovpn configuration file.
This file contains the necessary keys and settings required for connecting to the OpenVPN server.
Save the .ovpn file securely, as it will be needed for VPN client setup.
Saving the Configuration File
Save the .ovpn file on your computer or mobile device—this file is essential for establishing a VPN connection.
Installing the OpenVPN Client
On the main page of the web interface, you will find download links for official OpenVPN clients for various platforms, including:
- Windows
- macOS
- iOS
- Android
- Linux
Download and install the appropriate OpenVPN client for your device to proceed with the connection setup.
Connecting via OpenVPN Client
- Launch the installed OpenVPN client.
- Import the .ovpn configuration file (e.g., user.ovpn).
- Enable the VPN connection to obtain a new IP address assigned by the OpenVPN server.
Additional Security & Scaling Tips
- Use Strong Passwords: Avoid simple or easily guessable passwords. Secure credentials significantly reduce the risk of unauthorized access.
- Regular Updates: Keep track of new OpenVPN releases. Updating both the server and client software helps fix vulnerabilities and improve stability.
- Advanced Authentication: For tighter access control in a corporate environment, consider integrating OpenVPN with LDAP, RADIUS, or multi-factor authentication (MFA).
Scalability
OpenVPN is designed to grow with your organization—whether you're managing a small office or a large enterprise. As your company expands, you can add new users and servers seamlessly without overhauling the infrastructure.
