CentOS is a Linux distribution based entirely on Redhat. One can even say that it is a compatible copy from Redhat. But unlike the latter, it is totally free. She has also followed the same policy as Redhat, since each version is maintained for 7 years. Thus CentOS 5.1 will be updated until 31 March 2014. Let us say right away, CentOS is not for those who always want the latest versions of software, but rather to those who seek a solid cast, tested, whose programs have been tested, and want to enjoy the range provided in the form of RPM. It will be especially appreciated in a professional environment, or for people not wanting to spend their time watching and make updates.
To install it, it has a DVD or cdrom 6. It is also possible to install netinstall from an iso dedicated netinstall or launched from the live cdrom. So I tried first did a CentOS-5 LiveCD to see if my computer accepted it without problems. It works pretty well. It's like GNOME 2.16 desktop. Just the usual options to boot my old PC nolapic noapic acpi = force. All my PC and my devices are recognized without history. Automatic dhcp Ethernet connection. You end up with a keyboard that turns into U.S. en easily from the Preferences. Content of this test I decided to install from a DVD which I downloaded and burned the ISO image.
Quick Setup of CentOS via Bootable Disc
- Let's do a minimal install on the network (netinstall), in which only need to download an installation CD image from less than 9MB. Let's start, first you have to download the image. Iso and burn to a CD, USB device or whatever you want.
- Once saved, start the machine via USB device or CD-ROM to begin installation. Boot from CD and Select the installation language. Select the keyboard type.
- We are installing over the Internet, so that the next step select HTTP or FTP for the type of device that contains the packages to be installed.
- It's time to configure our interfaces, whether it is a particular machine, the network will normally configured by DHCP, so the default settings work correctly, otherwise we have to choose manual configuration, and specify the values IP, Netmask, DNS, Gateway, etc.
- Now enter the URL and path where the CentOS packages for network installation. At this point is recovering the image to proceed with the installation.
- After the welcome message, proceed to the partition configuration in / discs. If you receive a message similar to the following image, it means that the disc has not been initialized (empty) or who has any kind of problem in the partition table (old record, with a problem in the previous system installed, etc. ) If you have no data that ye preserve these records, accept initialization.
- Now is the time to setup disk partitioning. This depends on the needs of everyone, when in doubt you can let the system itself who you create a standard partitioning.
- You will see that you create a basic partition with swap space (swap) partition / boot to boot and the root / to house the system. At this point if you wish, you can modify any of the partitioning, LVM modify, create a software RAID, etc.
- Comes time to choose the boot loader, GRUB use if you want to install more systems, modify kernel parameters or select which one to use at startup, etc. The boot loader configuration we leave as is, without modification.
- You want you can specify a password for the grub, if you decide to do so, each time you boot your computer, the system will not pass until grub password, I leave it empty.
- Selecting partition to install the boot loader (first sector of boot partition or MBR):
- Back to indicate the possibility of reconfiguring our network cards, omit the same if you do not want.
- ow configure the hostname of your machine / Time Settings / Root password
- Finally you will have to choose the packages and applications to install. In this case, since a minimal installation unmark all, at this point you can select the appropriate software Esteem by clicking on "Customize software selection" you have more details available packages (Gnome or KDE graphical environment, virtualization applications, programs, etc). Now the system will check the dependencies of selected packages start disk formatting and installation, only have to wait to complete the download and installation, restart your computer and our system CentOS 5.4 is ready.
