等会整理教程

一、安装前序问题总集

问题：/var/run/yum.pid 已被锁定。
解答：分别运行以下命令：

rm -f /var/run/yum.pid
yum install glibc.i686

问题：-bash wget command not found
解答：安装wegt

yum -y install wget

二、准备安装

1、CentOS 7.5.1804下载地址：

http://mirror.nsc.liu.se/centos-store/7.5.1804/isos/x86_64/CentOS-7-x86_64-LiveGNOME-1804.iso

关于CentOS 7.5.1804的安装教程就自行百度搜索

2、导入epel安装源

yum install epel-release

3、添加VirtualBox安装源

cd /etc/yum.repos.d/
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

4、安装相关依赖包

yum install binutils qt gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms

5、查看yum中VirtualBox版本

yum list | grep VirtualBox

6、安装VirtualBox

yum install VirtualBox-6.0

sudo yum install ./VirtualBox-6.1-6.1.16_140961_el7-1.x86_64.rpm

7、建虚拟机安装系统

8、虚拟机建好后打开报错，kernel driver not installed (rc=-1908)

A、检查错误

sudo /sbin/vboxconfig

B、从上图看VirtualBox需要kernel-devel指定版本kernel-devel-3.10.0-862.el7.x86_64.rpm

下面是3个源，选一个安装即可

wget ftp://ftp.riken.jp/Linux/cern/centos/7/updates/x86_64/Packages/kernel-devel-3.10.0-862.el7.x86_64.rpm

wget https://cloud.zhulianjiuzu.com/linux/centos/centos7/kernel-devel-3.10.0-862.el7.x86_64.rpm

wget ftp://ftp.icm.edu.pl/vol/rzm3/linux-scientificlinux/7.2/x86_64/updates/security/kernel-devel-3.10.0-862.el7.x86_64.rpm

sudo yum install ./kernel-devel-3.10.0-1127.el7.x86_64.rpm
