Partitioning is a crucial process that helps in dividing your hard disk into various parts or sections, which can be utilized for different purposes. This article will provide you with an in-depth understanding of how to partition CentOS on Debian Server.
What is CentOS?
CentOS is a Linux distribution that serves as a free alternative to the enterprise-grade Operating System Red Hat Enterprise Linux (RHEL). It is a stable and reliable operating system that has been gaining popularity over the years.
What is Debian Server?
Debian is a widely used Linux distribution that is known for its stability, security, and reliability. A Debian Server primarily refers to the installation of Debian that is optimized for servers.
Why Partition CentOS on Debian Server?
Partitioning CentOS on Debian Server is beneficial in many ways. It helps in managing your data efficiently, organizing files, and improving performance. Partitioning your hard disk into multiple sections allows you to install different Operating Systems, host multiple websites or applications, and configure backup systems efficiently.
Requirements for Partitioning CentOS on Debian Server
You need to be familiar with the basics of Linux administration and partitioning. The following are the prerequisites:
- A CentOS DVD or image file
- A Debian DVD or image file
- A DVD or USB bootable drive
- A computer with internet access
- A backup of your existing data
Advantages of Partitioning CentOS on Debian Server
The following are some of the advantages of partitioning CentOS on Debian Server:
- Improved performance of your system
- Better management of data
- Effective organization of files and folder
- Improved system security and isolation
- Ability to install multiple Operating Systems on the same device
Disadvantages of Partitioning CentOS on Debian Server
Partitioning may also come with some limitations or disadvantages:
- Inability to retrieve data if the partition gets corrupted
- Inconvenience in resizing or deleting partitions
- Increased complexity and time taken to manage partitions
Partitioning CentOS on Debian Server: A Detailed Guide
Step 1: Create a Bootable Disk or USB Drive
The first step is to create a bootable disk or USB drive that contains the CentOS and Debian installation files. You can use any software or tool to create a bootable disk, such as UNetbootin, Rufus, or Etcher.
Step 2: Backup Your Data
Before you start partitioning, it is essential to backup your existing data. You can use external hard disks, cloud storage, or backup software to create a backup of your data.
Step 3: Boot from the Bootable Disk or USB Drive
Insert the bootable disk or USB drive into your computer, and restart it. Make sure to change the boot order in the BIOS settings so that the device boots from the bootable disk or USB first.
Step 4: Start the CentOS Installation Process
Once the computer boots from the bootable disk, the CentOS installation process will begin. Follow the prompts and select the partitioning option. Choose manual partitioning if you want to customize the partition sizes.
Step 5: Create Partitions
Click on the “create partitions” option and divide your hard disk into multiple partitions based on your requirements. You should have at least two partitions, one for the root file system and the other for swap space.
Step 6: Install CentOS
After creating partitions, you can proceed with the installation process. Choose a partition to install CentOS, and follow the prompts to complete the installation process.
Step 7: Install Debian on the Second Partition
Once you have installed CentOS, you can then proceed with Debian installation on the second partition. Boot from the Debian installation disk and choose manual partitioning. Create partitions as required and install Debian on the respective partition.
Step 8: Configure Grub Bootloader
Grub Bootloader is used to select which Operating System to boot into. Configure Grub bootloader by adding CentOS and Debian entries into it.
