Centos 安装桌面系统及虚拟化设置

1.首先minimal安装

2.切换阿里云

mv CentOS-Base.repo CentOS-Base.repo.backup

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

wget https://mirrors.aliyun.com/repo/epel-7.repo

yum clean all && yum makecache

3.安装:

yum groupinstall "X Window System"

yum groupinstall "GNOME Desktop" "Graphical Administration Tools"

安装完成后:startx

 

kvm虚拟化套件:

1）检查cpu是否支持虚拟化

[root@kevin ~]# grep vmx /proc/cpuinfo

如果有vmx信息输出，就说明支持VT;如果没有任何的输出，说明你的cpu不支持，将无法使用KVM虚拟机。

网卡加入网桥:

yum -y install bridge-utils

br0->eth0

[root@kevin ~]# yum -y install bridge-utils

[root@kevin ~]# systemctl restart network

 

配置KVM的网桥模式

[root@kevin ~]# cd /etc/sysconfig/network-scripts/

[root@openstack network-scripts]# cp ifcfg-eno1 ifcfg-br0

[root@openstack network-scripts]# cat ifcfg-br0

TYPE="Bridge"                                        //这一行修改为Bridge

PROXY_METHOD="none"

BROWSER_ONLY="no"

BOOTPROTO="none"

DEFROUTE="yes"

IPV4_FAILURE_FATAL="no"

IPV6INIT="no"

IPV6_AUTOCONF="yes"

IPV6_DEFROUTE="yes"

IPV6_FAILURE_FATAL="no"

IPV6_ADDR_GEN_MODE="stable-privacy"

NAME="br0"                                           //修改设备名称为br0

#UUID="fdbad04f-dae3-440e-8a8b-01d6a7bc9fe0"         //这一行注释

DEVICE="br0"                                         //修改设备为br0

ONBOOT="yes"

IPADDR="192.168.10.210"

PREFIX="24"

GATEWAY="192.168.10.1"

DNS1="8.8.8.8"

 

[root@openstack network-scripts]# cat ifcfg-eno1

TYPE="Ethernet"

BRIDGE=br0                                           //添加这一行

PROXY_METHOD="none"

BROWSER_ONLY="no"

BOOTPROTO="none"

DEFROUTE="yes"

IPV4_FAILURE_FATAL="no"

IPV6INIT="no"

IPV6_AUTOCONF="yes"

IPV6_DEFROUTE="yes"

IPV6_FAILURE_FATAL="no"

IPV6_ADDR_GEN_MODE="stable-privacy"

NAME="eno1"

UUID="fdbad04f-dae3-440e-8a8b-01d6a7bc9fe0"

DEVICE="eno1"

ONBOOT="yes"

#IPADDR="192.168.10.210"                          //注释掉这几行

#PREFIX="24"

#GATEWAY="192.168.10.1"

#DNS1="8.8.8.8"

 

重启网卡服务

[root@openstack network-scripts]# systemctl restart network
