CentOS (Community Enterprise Operating System) is forked from RedHat Linux, a Linux Distro fine-tuned for servers. Finally, the much awaited CentOS 7 is out.

Step 1: Download The ISO Image

To get a copy of CentOS 7 download from its source mirror. CentOS 7 is now shipping for 64 bit platforms, and currently there is no 32 bit ISO image. This is primarily due to the fact that most servers in production are 64 bit.

Step 2: Make A bootable Drive

After you have downloaded the ISO image, make a bootable USB drive. Since Centos 6.5, you can create usb drive bootable by simply transferring iso file to usb using dd command. As we found Unetbootin no longer works for CentOS 7.

# dd if=/iso/CentOS-7-x86_64-DVD-1602-99.iso of=/dev/sdb

* /dev/sdb is the usb device and make sure you have atleast 4.3 GB space.

Step 3: Begin Installation

To begin installation, click on the Install to Hard Drive icon on the desktop.

Step 4: Select Language And Keyboard

Select your preferred language as well as the Keyboard type you have. Take care not forget to choose the correct keyboard or else you will end up with a few scrambled keys.

Step 5: Change The Installation Destination

By default the Anaconda installer will choose automatic partitioning for your hard disk. Click on the Installation Destination icon to change this to custom partitioning.

Click on the hard drive you want to install CentOS 7 and under the Other Storage Options, choose I will configure partitioning then click Done.

Step 6: Select The Partitioning Scheme

Next select the partitioning scheme to use for the mount points. In this case choose Standard Partition.

Step 7: Create A Swap Space

You can create a swap space from one of the partitions and set the desired capacity, which is dependent on the RAM you have. Choose the File System for swap space as swap, and click on Reformat, though reformatting is optional. You can also name your swap space to whatever name you like but a name like swap is more descriptive.

Step 8: Create A Mount Point

The next step is to create a mount point where the root partition will be installed. Depending on your requirements you might need to put the boot, home and root partition on different mount points. For this case we shall have only one mount point /.

After this set the Label and Desired Capacity to whatever you wish. A rule of thumb is to use descriptive names for the Label especially if the computer is to be used by different system administrators.

Choose the file system as ext4 and click on reformat.

Step 9: Accept Changes

After completing Step 7 and Step 8 successfully click on Done button. A prompt window will appear with a summary of changes that will take place. If you are satisfied with them click Accept changes.

Step 10: Set Date And Time

Click on the clock icon under the localization menu and select a time zone from the map of the world, then click Done.

Step 11: Begin Installation

Now after configuring the System and Localization settings you can click on the Begin Installation button.

Installation will begin immediately and as it proceeds you need to set up a User account as well as the root password.

Step 12: Set Up Root Password

Click on the root password option and enter a password and confirmation of the same then click Done.

Step 13: Create a User Account

The next step is to create a user account. Enter the correct details and if this is the administrator account, tick Make this user administrator and Require a password to use this account for security purposes.

Step 14: Complete Installation

The installer should complete installing the software and the bootloader. Have a look on how to Set Linux Grub Password with Examples.

Once complete you should get a success message, after which you can click quit.
Logout from the Live system and login to your new installation.

Finally once you login to your CentOS 7 accept the EULA agreement and enjoy!

New Features in CentOS 7

The following are some of the notable feature in CentOS 7:

Gnome 3 Desktop Environment

CentOS 7 comes with Gnome 3 which is very convenient when you have a touch screen.

It also comes with Gnome Classic for those that want the look and feel of Gnome 2.

CentOS 7 comes with GRUB 2 which solves dual booting problems with other Linux distros that have been using GRUB 2, like Ubuntu. This is an improvement from CentOS 6.5 which used GRUB Legacy and was a problem when dual booting. Now you can do your installation without concerns of GRUB issues.

CentOS 7 has support for the xfs file system which is suitable especially in a distributed type of environment. XFS is known for its ability to handle parallel I/O compared to ext4.

CentOS 7 will also be shipping with MariaDB, a replacement for MySQL.

Conclusion

CentOS 7 has greatly improved from version 6.5 and now is easier to adopt it as a Desktop OS compared to its predecessor. For those that probably cannot keep up with Fedora releases every 6 months, CentOS 7 is a good consideration. Try it out today!

Mengenal Macam-Macam Distro Linux dan Turunannya – Distro? apaan tuh? yang jual baju itu ya? ckkkkkk….bukan bro… di Linux, Distro Linux itu singkatan dari Distribusi Linux, adalah sebutan untuk sistem operasi komputer dan aplikasinya, merupakan keluarga Unix yang menggunakan kernel Linux.
Distribusi Linux bisa berupa perangkat lunak bebas dan bisa juga berupa perangkat lunak komersial seperti Red Hat Enterprise, SuSE, dan lain-lain.

Ada banyak distribusi atau distro Linux yang telah muncul. Beberapa bertahan dan besar, bahkan sampai menghasilkan distro turunan, contohnya Distro Debian GNU/Linux. Distro ini telah menghasilkan puluhan distro anak, antara lain Ubuntu, Knoppix, Xandros, DSL, dan sebagainya.

Beberapa Contoh Distro Linux

1. Ubuntu

Ubuntu merupakan distro Linux yang paling populer diantara distro-distro lainnya. Sifatnya yang stabil serta user friendly membuatnya sangat diminati oleh publik. Ubuntu juga merupakan distro Linux yang paling cocok bagi pengguna awam yang baru belajar menggunakan Linux, karena memang distro inilah yang paling gampang pengoperasiannya. Dukungan komunitas yang besar membuat anda tidak akan pernah kehabisan tempat untuk bertanya.

2. Opensuse
Opensuse pertama kali dipublikasikan pada tahun 1992 oleh 4 orang maniak Linux berkebangsaan jerman. Project mereka diberikan nama SUSE yang merupakan kepanjangan dari (Software und System Entwicklung). Edisi yang tersedia saat ini adalah openSuse dan Suse Linux Enterprise.

3. Fedora

Fedora pertama kali dirilis pada tahun 1995, dikembangkan oleh 2 orang yang bernama Bob Young dan Marc Ewing dibawah nama perusahaan Red Hat Linux. Walaupun dirilis sudah sejak lama namun fedora baru mulai populer pada tahun 2004. Edisi yang tersedia dari distro ini adalah fedora dan Red Hat enterprise.

4. Debian
Debian GNU Linux pertama kali di publikasikan 1993. Pembuatnya adalah Ian Murdock. Debian GNU Linux merupakan sebuah project non-komersil yang dikembangkan secara bersama-sama oleh ratusan programmer diwaktu senggang mereka. Debian tumbuh menjadi distro yang besar dan populer, memiliki komunitas yang besar, serta menelurkan berbagai macam distro-distro turunan.

5. Mandriva
Mandriva linux pertama kali diluncurkan pada tahun 1998 oleh Gael Duval dibawah nama Mandrake Linux. Pada awalnya mandriva merupakan hasil olahan dari Red Hat dengan berbagai sentuhan tambahan, namun lambat laun mandriva memiliki fungsi-fungsi sendiri yang membuatnya lebih user friendly.

Pertama kali diluncurkan pada tahun 2005 oleh Bill Reynolds atau lebih dikenal dengan julukan “texstar”. Sebelum Bill Reynolds menciptakan PclinuxOS, ternyata texstar adalah salah satu developer yang cukup terkenal dari Mandrake Linux. Edisi yang tersedia adalah MiniMe, Junior and BigDaddy.

8. Slackware
Distro yang diciptakan oleh Patrick Volkerding pada tahun 1992 ini, merupakan salah satu distro Linux lawas yang berhasil bertahan hingga kini dan bahkan menjadi salah satu distro yang paling populer.

9. Gentoo Linux
Gento disusun pada tahun 2000 oleh Daniel Robbins. Ide dasar dari distro ini adalah mengizinkan user untuk meng-compile sendiri source code dari Linux ataupun aplikasi program ke sistem milik mereka. Sebenarnya distro yang satu ini diperuntukkan bagi user-user level lanjut dengan jam terbang yang sudah tinggi.

10. Centos
Centos pertama kali dipublikasikan pada tahun 2003. Centos merupakan hasil re-build source code RedHat Enterprise Linux oleh sebuah komunitas. Tujuan distro ini adalah untuk menciptakan sebuah distro yang menyediakan update secara cepat.
