CentOS 7 Installation VirtualBox

Yesterday to centos6.5 installed VirtualBox, installed a day did not, today idle nothing, try Centos7, the results of the success of PS younger brother is also a beginner Linux, many places just found a solution, but do not know why, MO see

Strange O (∩_∩) o ha!

1, install CENTOS7, this does not say, the installation of Centos7 than the old version is much simpler.

2, the network settings, just after the installation of CentOS with ifconfig view found no IP address, solution:

cd/etc/sysconfig/network-scripts/

VI ifcfg-eno16777736 #注意, we usually see is ifcfg_eth0, specifically what, with ifconfig look.

Onboot=yes #将onboot设为yes

Then restart the network card:/etc/init.d/network restart

2, installation VirtualBox:

1> Download the VirtualBox rhel repositories configuration file:

         CD/ETC/YUM.REPOS.D         wget Http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

2> install Rpmforge.

First download the corresponding RPM file from http://pkgs.repoforge.org/rpmforge-release/, I downloaded the rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm, the specific version

For information, please refer to: Http://wiki.centos.org/zh/AdditionalResources/Repositories/RPMForge.

<span style= "Font-family:courier New;" >       RPM-IVH rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm</span>

3> Installing dkms (Dynamic Kernel Module)

        Yum Install dkms

4> Install the development environment and kernel:

<span style= "Font-family:courier New;" >      yum groupinstall "Development Tools"       Yum install kernel-devel</span>

5> Installing QT and qt-

       Yum Install QT qt-x11

6> installation VirtualBox

I was first downloaded on the official website, the version is virtualbox-4.3-4.3.26_98988_el7-1.x86_64.rpm, https://www.virtualbox.org/wiki/Downloads

       Yum Install virtualbox-4.3-4.3.26_98988_el7-1.x86_64.rpm

7> Installation Extensions:     

There's a problem with this place.

VBoxManage:error:Details:code ns_error_failure (0x80004005), Component Extpackfile, interface Iextpackfile, callee NsI Supports
VBoxManage:error:Context: "Install (Freplace, NULL, Ptrprogress.asoutparam ())" At line 1140 of file VBoxManageMisc.cpp

But now the system has virtualbox, so that this problem can be ignored, continue the next.
