RHCA CL220實戰系列(一)之KVM部署CloudForms

1. 概述數據庫

    紅帽公司推出了混合雲CloudForms解決方案,redhat的宗旨在於經過CloudForms可以管理全部的基礎架構設施如RHEV,VMware和雲(AWS和OpenStack),實現集中化管理平臺。CloudForms由Engine引擎,VMDB虛擬數據庫等組成,其中Engine做爲CloudForms中核心功能,負責CloudForms的平常管理工做。api

    CloudForms Engine簡稱CFME,是一個已經制定好的虛擬機,經過部署該虛擬機,能夠快速的部署CloudForms的環境。因爲是虛擬機,根據環境的不一樣,能夠部署在不通的虛擬化平臺上,而且根據不通的虛擬化平臺,由不通的虛擬機提供,如VMware平臺,RHEV平臺,OpenStack平臺等。本文以部署在KVM爲例,講述CloudForms Egine的部署。架構


2. 經過KVM部署CloudFormsdom

  1. 創建和修改虛擬機的配置文件ide

[root@ChuangYiYuan_10_16_2_9 ~]# cp /etc/libvirt/qemu/CentOS-5.9.xml /etc/libvirt/qemu/cfme.xml

修改以下內容:ui

a、名字        <name>cfme</name>rest

b、uuid        <uuid>ba845a90-8670-4b89-9451-3a111372950c</uuid>    經過uuidgen生成一個新的號碼orm

c、內存        <memory unit='KiB'>4194304</memory>xml

d、CPU         <vcpu placement='static'>4</vcpu>blog

e、啓動順序    <boot dev='hd'/>

f、磁盤文件

<disk type='file' device='disk'>                                                   #磁盤類型爲file
    <driver name='qemu' type='qcow2' cache='none'/>                                #驅動類型和格式
    <source file='/var/lib/libvirt/p_w_picpaths/cfme.qcow2'/>                            #磁盤文件路徑,從CloudForms中解壓獲取
    <target dev='vda' bus='virtio'/>                                               #磁盤名字和總線類型爲virtio
    <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>    @@@注意,要刪除@@@,不然總線的地址會衝突
</disk>
<disk type='file' device='disk'>
    <driver name='qemu' type='qcow2' cache='none'/>
    <source file='/var/lib/libvirt/p_w_picpaths/cfme_vdb.qcow2'/>     #磁盤所在路徑,後續建立
    <target dev='vdb' bus='virtio'/>                            #磁盤爲vdb
</disk>

g、網卡

<interface type='network'>
    <mac address='52:54:00:00:00:0c'/>        #mac地址
    <source network='br-eth0'/>               #橋接網卡,@@注意@@@此處用的是ovs的網橋,若是KVM的網橋,請修改成br0
    <virtualport type='openvswitch'></virtualport>    #因爲使用openvswitch網橋,須要添加,br0則不用
    <model type='virtio'/>
</interface>

h、VNC

<graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0'>        #用於VNC鏈接,防止沒有圖形界面
   <listen type='address' address='0.0.0.0'/>
</graphics>

修改完以後,虛擬機的配置文件內容以下:

cat /etc/libvirt/qemu/cfme.xml    
<domain type='kvm'>

2. 獲取CloudForms的虛擬機

    爲了方便你們使用,我已經放置到網盤中,鏈接路徑:網盤地址:http://pan.baidu.com/s/1hrrmtec

3. 解壓CFME虛擬機

[root@foundation0 cfme]# tar -xvf cfme-rhevm-5.3-47.x86_64.rhevm

#將CFME文件拷貝至KVM虛擬機目錄,並更名字

[root@foundation0 cfme]# ll -h p_w_picpaths/a2dd2ac4-7a94-4c90-9c86-6a45477cbbb9/143fbb49-1441-4a1a-beaf-f9c6433f3566

#基於磁盤鏡像文件,建立backing file鏈接,backing file相似於Linux下的軟連接,是一個只讀的文件,增量的寫內容,都會保存至新的文件,本文即cfme.qcow2中
[root@foundation0 cfme]# qemu-img create -f qcow2 -b /var/lib/libvirt/p_w_picpaths/cfme /var/lib/libvirt/p_w_picpaths/cfme.qcow2

4. 啓動虛擬機,並獲取VNC的端口號

[root@foundation0 ~]# virsh create /etc/libvirt/qemu/cfme.xml        #加載到KVM域內
Domain cfme created from /etc/libvirt/qemu/cfme.xml
[root@foundation0 ~]# virsh
Welcome to virsh, the virtualization interactive terminal.
Type:  'help' for help with commands
       'quit' to quit
virsh # list --all

----------------------------------------------------
 6     cfme                           running
virsh # vncdisplay cfme                                  #查看VNC的端口號,即5900
:0

[root@foundation0 ~]# ifconfig 
br-eth0   Link encap:Ethernet  HWaddr 00:E0:81:DF:9C:DB  
          inet addr:10.16.0.60  Bcast:10.16.1.255  Mask:255.255.254.0        #KVM母機的ip地址,使用該地址和VNC端口鏈接到虛擬機
          inet6 addr: fe80::5849:18ff:fee2:5c4e/64 Scope:Link

          RX bytes:54255684244 (50.5 GiB)  TX bytes:56112174185 (52.2 GiB)

5. 使用VNC客戶端鏈接至CFME虛擬機

配置成功,界面以下,默認的username:admin,password:smartvm

wKiom1aiBp_gudIJAAEGolNdLgQ540.jpg


5. CloudForms初始化

    使用admin:smartvm登錄到系統中,能夠自行初始化操做,初始化的操做包括以下內容:

wKioL1aiB-3Qa0g4AAK4e1EPNj8145.jpg

選擇8,配置數據庫便可,執行1生成key,選擇內部internal,設置數據庫區域爲0,執行完以後,顯示以下

wKioL1aiCQnjIhHgAAHLc7akxDs571.jpg

查看CloudForms的狀態信息

wKioL1aiCV6gB5n5AAK-WKIAiiU598.jpg

6. 登錄CloudForms

輸入https://10.16.1.197便可登錄至CloudForms,因爲是https,所須要確認證書,確認證書以後,將會進入到CloudForms的管理界面

wKioL1aiCfWAGeaLAALbEz3AvXQ759.jpg

輸入admin:smartvm便可登錄,登錄以後頁面內容
