ovirt4.2环境安装

系统安装

首先添加ovirt官方repo

yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm

安装createrepo工具

yum install -y createrepo

修改YUM配置

接下来修改YUM配置，用来保留随后进行安装时候会下载到的所有包。注意这一步一定要放在添加ovirt官方repo后面，否则将上面那个ovirt-release42.rpm也会缓存下来，我们一会儿要做的离线包不需要它。

vi /etc/yum.conf
修改keepcache = 1
制作ovirt-engine离线安装包

刚才准备好的这两台一模一样的设备先用一个，跟之前笔记中的过程一样，先正常安装ovirt-engine。
yum install -y ovirt-engine --nogpgcheck
刷刷刷的安装一大堆东西，装完之后就行了，不需要进行后面engine-setup的过程，我们要的只是这些rpm包。
生成repo相关数据
cd /var/cache/yum/x86_64/7/
createrepo -v ./
至此，ovirt-engine的离线安装包就准备好了，使用WinSCP连过去将这个x86_64的文件夹拷出来。
离线安装ovirt-engine
重新安装一遍CentOS 7最小化模式系统，啥都不用装，还用WinSCP将之前拷出来的那个x86_64文件夹传回来至/var/cache/yum/里面

解决方法:增加一个配置文件如下

SSO_CALLBACK_PREFIX_CHECK=false
重启ovirt-engine服务
service ovirt-engine restart
即可
制作Host离线安装包
Host离线安装包的制作过程跟上面的ovirt-engine差不多，但是由于host里面用到的包都是由engine从web管理界面中执行的安装脚本在后台自动完成的，因此我们在配置完yum.conf让它保留cache后，正常从engine的管理后台鼠标流将这台服务器添加到虚拟化集群里面，并等待后台脚本从官网正常下载安装完成所有需要的包，等这台host完成安装，状态变成up后，来到yum的缓存目录里面生成一下repo相关文件后WinSCP拷出来就行了
首先添加ovirt官方repo
yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
安装createrepo工具
systemctl stop firewalld
setenforce 0

vim /etc/yum.conf
修改keepcache = 1
yum install -y createrepo
yum -y update
cd /var/cache/yum/x86_64/7/
createrepo -v ./

创建本地repo配置文件
cd /etc/yum.repo.d
mkdir bak
mv *.repo ./bak
vi local.repo
[local]
name=local-repo
baseurl=file:///var/cache/yum/x86_64/7
gpgcheck=0
enabled=1

同理在进行离线安装Host的时候也是将上面拷出来的这个文件夹怼到新的空白服务器里，创建/etc/yum.repo.d/local.repo文件（跟上面一样），到这里就不用管了，直接在engine的web界面鼠标流添加这台host，所需要的包就会自动从本地的源里面进行安装啦
注意：因为KVM是依赖硬件虚拟化，所以需要开机英特尔的CPUvt-x技术，AMD-V
虚拟机在CPU选项处设置
物理机在主板boss处设置

离线安装包后续会上传到百度云：
