kvm+webvirtmgr在centos7上的部署

#!/bin/bash
#+++++++++++++++++++++++++++++++++++++++++++++++++++++++安装配置kvm并创建虚拟机+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#验证cpu是否支持kvm
egrep '(vmx|svm)' /proc/cpuinfo 

#然后需要在bios设置中打开cpu virtual technology!!!!!!!

#关闭selinux
vi /etc/sysconfig/selinux
selinux=disabled

#关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

#更换yum源(可选,一般不用换)
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache

#安装依赖环境
yum install epel-release net-tools vim unzip zip wget ftp -y

#安装kvm及其依赖项
yum install qemu-kvm libvirt virt-install bridge-utils -y

#验证安装结果
lsmod | grep kvm 

#开启kvm服务，并且设置其开机自动启动
systemctl start libvirtd
systemctl enable libvirtd
#配置网络桥接模式
#手动修改  配置网桥模式，先将 /etc/sysconfig/network-scripts/ 目录下的网卡配置文件备份一份(不要备在当前目录以及子目录下，其他目录随意)

#a. 创建 ifcfg-br0 文件，内容如下：

BOOTPROTO=static
DEVICE=br0
TYPE=Bridge
NM_CONTROLLED=no
IPADDR=192.168.1.95
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=61.177.7.1
DNS2=8.8.8.8
#b. 移除掉原来的 ifcfg-enp0s25 ,重新创建该文件，内容如下：

BOOTPROTO=none
DEVICE=enp0s25
NM_CONTROLLED=no
ONBOOT=yes
BRIDGE=br0

#c.重启网络服务
systemctl restart network

#安装虚拟机

#准备虚拟机镜像文件,把该文件放到 /home/iso（没有可创建）目录下

#创建虚拟机
mkdir -p /home/kvm-bak

virt-install -n xiaocanan_media -r  --vcpus= --os-type=linux --accelerate -c /home/iso/CentOS--x86_64-Minimal-.iso --disk path=/home/vmdisk_pool/xiaocanan_media.img,format=qcow2,bus=ide --network bridge=br0 --vnc --vncport= --vnclisten=0.0.0.0 --force --autostart

#关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

#关闭selinux
vi /etc/sysconfig/selinux
selinux=disabled

#用vnc连接虚拟机,进行虚拟机操作系统的安装

#手动启动虚拟机
virsh list --all
virsh start virt-centos

#yum源的配置及所需软件包

#设置ssh免密登录
 1. vi /etc/ssh/sshd_config
    RSAAuthentication yes   #新版本ssh可能不需要配置此项
　　PubkeyAuthentication yes
　　AuthorizedKeysFile      .ssh/authorized_keys
 2.重启sshd服务:systemctl restart sshd
 3.生成证书公私钥
    ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
    cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
 4.chmod 600 ~/.ssh/authorized_keys

 #免密登录远程服务器
  cat ~/.ssh/id_rsa.pub | ssh 远程用户名@远程服务器ip 'cat - >> ~/.ssh/authorized_keys'

#启动webvirtmgr server
nohup /var/www/webvirtmgr/manage.py runserver 0:8000

#切记!!!! webvirtmgr第一次一定要手动运行,不然会提示密码验证失败
#切记!!!! 使用webvirtmgr创建windows虚拟机时不能选virtio,因为没有相应驱动的话,硬盘和网卡都会无法识别
