ovirt4.2環境安裝

系統安裝


 

首先添加ovirt官方repo

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

安裝createrepo工具

yum install -y createrepo 

修改YUM配置

接下來修改YUM配置，用來保留隨後進行安裝時候會下載到的所有包。注意這一步一定要放在添加ovirt官方repo後面，否則將上面那個ovirt-release42.rpm也會緩存下來，我們一會兒要做的離線包不需要它。

1. vi /etc/yum.conf
   修改keepcache = 1 
   

   製作ovirt-engine離線安裝包

   
   剛纔準備好的這兩臺一模一樣的設備先用一個，跟之前筆記中的過程一樣，先正常安裝ovirt-engine。

2. yum install -y ovirt-engine --nogpgcheck
   刷刷刷的安裝一大堆東西，裝完之後就行了，不需要進行後面engine-setup的過程，我們要的只是這些rpm包。 
   

   生成repo相關數據

3. cd /var/cache/yum/x86_64/7/

4. createrepo -v ./
   至此，ovirt-engine的離線安裝包就準備好了，使用WinSCP連過去將這個x86_64的文件夾拷出來。 
   

   離線安裝ovirt-engine

   重新安裝一遍CentOS 7最小化模式系統，啥都不用裝，還用WinSCP將之前拷出來的那個x86_64文件夾傳回來至/var/cache/yum/裏面
   關閉防火牆和SE
   啓動： systemctl start firewalld
   關閉： systemctl stop firewalld
   查看狀態： systemctl status firewalld 
   開機禁用 ： systemctl disable firewalld
   開機啓用 ： systemctl enable firewalld 
   systemctl stop firewalld
   setenforce 0 
   

   創建本地repo配置文件

5. cd /etc/yum.repo.d

6. mkdir bak

7. mv *.repo ./bak

8. vi local.repo 
   [local]
   name=local-repo
   baseurl=file:///var/cache/yum/x86_64/7
   gpgcheck=0
   enabled=1 
   

   安裝ovirt-engine

   
   

9. yum install -y ovirt-engine 
   配置ovirt-engine

  製作Host離線安裝包

  Host離線安裝包的製作過程跟上面的ovirt-engine差不多，但是由於host裏面用到的包都是由engine從web管理界面中執行的安裝腳本在後臺自動完成的，因此我們在配置完yum.conf讓它保留cache後，正常從engine的管理後臺鼠標流將這臺服務器添加到虛擬化集羣裏面，並等待後臺腳本從官網正常下載安裝完成所有需要的包，等這臺host完成安裝，狀態變成up後，來到yum的緩存目錄裏面生成一下repo相關文件後WinSCP拷出來就行了 
  

  首先添加ovirt官方repo

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

  安裝createrepo工具

  systemctl stop firewalld
  setenforce 0 
  

1. vim /etc/yum.conf
   修改keepcache = 1 
   yum install -y createrepo 
   yum -y update 
   
   

2. cd /var/cache/yum/x86_64/7/

3. createrepo -v ./ 
   
   

   創建本地repo配置文件

4. cd /etc/yum.repo.d

5. mkdir bak

6. mv *.repo ./bak

7. vi local.repo 
   [local]
   name=local-repo
   baseurl=file:///var/cache/yum/x86_64/7
   gpgcheck=0
   enabled=1 
   
   同理在進行離線安裝Host的時候也是將上面拷出來的這個文件夾懟到新的空白服務器裏，創建/etc/yum.repo.d/local.repo文件（跟上面一樣），到這裏就不用管了，直接在engine的web界面鼠標流添加這臺host，所需要的包就會自動從本地的源裏面進行安裝啦
   注意：因爲KVM是依賴硬件虛擬化，所以需要開機英特爾的CPUvt-x技術，AMD-V
   虛擬機在CPU選項處設置
   物理機在主板boss處設置

離線安裝包後續會上傳到百度雲：
