System requirements for OpenPanel installation

Before installing OpenPanel, ensure your server meets the following requirements:

• Operating system: A Linux-based distribution such as Debian or Ubuntu is recommended.
• RAM: Minimum of 1 GB (2 GB or more is recommended for optimal performance).
• Disk space: At least 20 GB of free storage.

Step 1: Prepare your server for OpenPanel installation

Before diving into the installation process, it’s crucial to prepare your server. Follow these steps to ensure a smooth installation:

1. Log in to your server

Use SSH to connect to your server. Replace server_ip with your server’s IP address:

$ ssh root@server_ip

2. Update your server

Update the package list and upgrade installed packages to ensure your server is up-to-date:

$ sudo apt update && apt upgrade -y

3. Install necessary dependencies

OpenPanel requires certain packages to function properly. Install them with the following command:

$ sudo apt install wget curl gnupg -y

4. Set the correct timezone

Use the timedatectl command to configure the correct timezone for your server:

$ sudo timedatectl set-timezone your_time_zone

Replace your_time_zone with the appropriate timezone, e.g., America/New_York.

Step 2: Download and install OpenPanel

Now that your server is ready, you can proceed with downloading and installing OpenPanel.

1. Download OpenPanel repository

Add the OpenPanel repository to your system using the following commands:

$ sudo wget -qO - http://openpanel.com/download/openpanel.gpg | apt-key add -
$ sudo echo "deb http://openpanel.com/repo stable main" > /etc/apt/sources.list.d/openpanel.list

2. Update package list

Refresh your package list to include the OpenPanel repository:

$ sudo apt update

3. Install OpenPanel

Install OpenPanel with the command below:

$ sudo bash <(curl -sSL https://openpanel.org)

This process may take a few minutes as the necessary packages are downloaded and installed.

4. Verify installation

After the installation is complete, check the status of the OpenPanel service to ensure it’s running:

$ sudo systemctl status openpanel

If it’s not running, start the service:

$ sudo systemctl start openpanel

Step 3: Access the OpenPanel web interface

Once OpenPanel is installed, you can access its web interface to manage your server.

1. Open your browser

Enter the following URL in your browser:

http://server_ip:4084

Replace server_ip with your server’s IP address.

2. Log in to OpenPanel

Use the default credentials to log in. The default username is root, and the password is the same as your server’s root password.

3. Change the default password

For security purposes, change the default password immediately after logging in.

Step 4: Configure OpenPanel for your needs

After logging into OpenPanel, you can begin configuring it to meet your requirements. Here’s a breakdown of key configurations:

Configure web hosting

1. Navigate to the “Web Hosting” section in OpenPanel.
2. Add your domain or subdomain.
3. Configure the root directory for your website files.
4. Set permissions and enable SSL if required.

Set up a MySQL database

1. Go to the “Databases” section.
2. Create a new MySQL database and user.
3. Assign the user to the database and set appropriate permissions.

Email server configuration

1. Navigate to the “Email” section.
2. Add email accounts for your domain.
3. Configure spam filters and set up email forwarding as needed.

DNS configuration

1. Go to the “DNS” section.
2. Add or edit DNS records such as A, MX, and TXT records.
3. Ensure your domain’s nameservers point to your server.

Step 5: Secure your OpenPanel installation

Securing your OpenPanel installation is critical to protecting your server from unauthorized access.

1. Enable a firewall

Install and configure UFW (Uncomplicated Firewall):

$ sudo apt install ufw -y
$ sudo ufw allow 4084/tcp
$ sudo ufw enable

2. Install an SSL certificate

Use Let’s Encrypt to secure your OpenPanel interface with HTTPS:

$ sudo apt install certbot -y
$ sudo certbot certonly --standalone -d your_domain

3. Change the default port

Modify the OpenPanel configuration file to use a custom port:

$ sudo nano /etc/openpanel/config.ini

Change the default port (4084) to a custom port, then restart OpenPanel:

$ systemctl restart openpanel

4. Regular updates

Keep OpenPanel and your server software updated to protect against vulnerabilities:

$ apt update && apt upgrade -y
