The Perfect Server Install Debian 9: A Detailed Explanation
Step 1: Download Debian 9
The first thing you need to do is download the Debian 9 installation image from the official website. Choose the appropriate image for your hardware architecture and download it to your local computer.
Once the download is complete, you’ll need to create a bootable USB or DVD drive from the image. You can use software like Rufus or Etcher to create a bootable drive.
Step 2: Boot from the Installation Media
Insert the bootable media into the target server and boot from it. You may need to change the boot order in the BIOS or UEFI firmware settings to prioritize the installation media.
When the system starts, you’ll see the Debian 9 installer boot menu. Choose the “Install” option to start the installation process.
Step 3: Choose Your Language and Location
After selecting the “Install” option, you’ll be prompted to choose your language and location. Choose the appropriate options and click “Continue.”
Step 4: Configure Your Network Settings
The next step is to configure your network settings. Choose your network interface and enter the appropriate settings, such as IP address, netmask, gateway, and DNS server. If you’re not sure about these settings, consult with your network administrator.
Step 5: Partition Your Hard Drive
The next step is to partition your hard drive. You can choose between several partitioning schemes, such as Guided, Manual, or LVM. If you’re not sure about these settings, choose the Guided option for a simple installation.
Make sure to allocate enough space for the root partition (/), swap partition, and any other mount points you need.
Step 6: Install the Base System and Software
After partitioning your hard drive, you’ll need to install the base system and software packages. The installer will guide you through the process and ask you to choose the software you want to install.
You can choose between several software categories, such as web server, database server, SSH server, and standard system utilities. Choose the appropriate packages and click “Continue.”
Step 7: Configure Your System
Once the installation is complete, you’ll need to configure your system. This includes setting up a root password, creating a user account, setting the timezone, and other basic settings.
The installer will guide you through the process and ask you to enter the necessary information.
Step 8: Install Additional Software Packages
After the base system is installed, you can install additional software packages to customize your server. You can use the “apt-get” command to install packages from the official Debian repositories or other third-party sources.
Make sure to install only the software you need and avoid installing unnecessary packages that could slow down your system or compromise its security.
Step 9: Secure Your Server
Security is a critical aspect of any server installation. You must take appropriate measures to secure your server and protect it from unauthorized access and attacks.
Some of the security measures you should consider include:
- Enabling a firewall
- Disabling unnecessary services and ports
- Enabling SSH key-based authentication
- Updating your system regularly
- Installing a security software like fail2ban
Step 10: Test Your Server
Once you’ve completed all the above steps, it’s essential to test your server to make sure everything is working correctly. You can test your server’s functionality by accessing it through a web browser, SSH client, or other applications.
If you encounter any issues, refer to the Debian 9 documentation or seek help from the Debian community.
