Install Centos 7 On Virtualbox

I have download Centos 6.5 and 6.5 and then install it on Virtualbox , but it is wonder that it do not prompt to ask to select what package need to be install during the installation process .

I checked that only 700M HD space is used to insall , therefore , it should be only minimal installation .

what I have download is CentOS-6.5-i386-bin-DVD1 and CentOS-6.6-i386-bin-DVD1 , the file size is 3.8G .

would advise how can I select package to install or run full install ?

thanks.

I am getting Following output after running installation of some packages.

it gives me such error

rpmts_HdrFromFdno: Header V3 RSA/SHA1 Signature, key ID c105b9de: BAD


What causing this ? i have downloaded the latest key from
http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 and check it, the key is fine under my system /etc/pki/rpm-gpg

Configuration files of respo are also fine under /etc/yum.rpos.d/CentOS-Base.repo

Kindly help

Hello

I try to install the epel repository so I can install ejabberd.

I do not have epel, it seems :

Code:

[root@serv src]# ls /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-fasttrack.repo  CentOS-Media.repo  CentOS-Vault.repo  n2.repo

So I try to install epel :

Code:

[root@serv src]# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Preparing...                ########################################### [100]
	package epel-release-6-8.noarch is already installed

But when I try to install ejabberd :

Code:

[root@serv src]# yum install ejabberd

Hello all:


I am truly a newbie at this and it won't be long before you can see that. I am trying to install centos 6.2 on a DELL P.E 2850 with 16GB or RAM;but I get the following error and the instal halts: "you do not have enough RAM to install CENTOS on this machine". I have tried several restarts but nothing so far. Please - any suggestions?

IMPORTANT: I wasn't sure I could download the file correctly so I bought the discs.



Thanks!
Karl

CentOS Linux 7 (core)
Kernel 3.10.0-299.el17.x86_64 on an x86_64
local host login:kd
[kd@localhost ~]$

The above is what displays on a black screen.
The program was d/l to DVD and then installed on a usb stick and booted from there. No password.

This is the second installation. On the first, a pw was specified but at login, it would not accept input from the keyboard except the enter key which resulted in Incorrect Password.

Help would be much appreciated.

We're unable to upgrade our environment beyond CentOS 5.10. This is a webserver that has certain reliances to the specific version of the OS, long story short.

I was asked to install a plugin for Redmine that requires at least ruby 1.8.7 so I cloned our VM as a new machine to test functional checkout. The problem is, the existing installation of Ruby was also installed ad hoc (not from any repo or yum methods) and it's currently at 1.8.5. The 1.8.7 version I tried to install gives me the following:
Quote:
# rpm -Uvf ruby-1.8.7.374-2.el6.x86_64.rpm warning: ruby-1.8.7.374-2.el6.x86_64.rpm: Header V3 RSA/SHA1 signatu NOKEY, key ID c105b9de error: Failed dependencies: rpmlib(FileDigests) <= 4.6.0-1 is needed by ruby-1.8.7.374-2.el6.x86_64 ruby-libs = 1.8.7.374-2.el6 is needed by ruby-1.8.7.374-2.el6.x86_64 rpmlib(PayloadIsXz) <= 5.2-1 is needed by ruby-1.8.7.374-2.el6.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-irb-1.8.5-31.el5_9.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-rdoc-1.8.5-31.el5_9.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-ri-1.8.5-31.el5_9.x86_64
It appears as though this particular version was intended for CentOS 6 and, as I've known from previous experience, dependency hell is upon me. So, the question becomes, has anyone successfully upgraded ruby without tinkering with the OS version upgrade and, if so, might you have a HOWTO that prevents dependency hell? This, short of installing from source, is headed in the wrong direction real quick so I'm trying to stick with the RPM method. But, obviously, I'll listen to anything at this point.

I had Kali and Linux Mint installed and erased Mint to install Centos7. Grub was totally deleted and I could only boot into grub recovery. Many hours of cussing later I got Kali back, I can see Centos filesystem mounted on my desktop and in disk utility. I never finished setting Centos up as I was rushed out the door which probably caused the problem in the first place, for some reason it's raid and although it's 2 harddrives they are not set up for raid and 1 is Kali and 1 is Centos. The Centos boot folder is still empty after running grub-install on it twice and it does not show in grub. How do I get Centos as an option?

I have a Toshiba Laptop that had a Dual Boot of Windows 7 and Linux Mint 17 on it and both OS's worked fine. I've been wanting to use CentOS 7 as my primary OS so that I can become more familar with RPM management and proceeded to remove my Mint installation and replace it with the CENTOS 7 installation, and the install completed successfully. HOWEVER, here's my problem.....

When my laptop starts up, I don't see GRUB nor do I have any option of selecting whether to run Windows or CentOS. It automatically loads up Centos 7. When I do a 'sudo fdisk -l', I can see that SDA1 is an NTFS drive, and when I try the following 'sudo mount /dev/sda1 /media/Main\ Drive' I get an error message saying that I can't mount an NTFS drive.

Am I missing something or is there a way to access my Windows files from within Centos. I was able to do this with Mint without an issue, but unable to see any of my windows drives because I can't mount an NTFS drive.

I have no problem with keeping CENTOS as my only OS on this laptop, however, I do need to access the files from the Window's partition, and if anyone can help me to access my files, that would be totally awesome.

Thank you in advance for reading through this and for any help offered.....
