1. 概述

    红帽公司推出了混合云CloudForms解决方案,redhat的宗旨在于通过CloudForms能够管理所有的基础架构设施如RHEV,VMware和云(AWS和OpenStack),实现集中化管理平台。CloudForms由Engine引擎,VMDB虚拟数据库等组成,其中Engine作为CloudForms中核心功能,负责CloudForms的日常管理工作。

    CloudForms Engine简称CFME,是一个已经制定好的虚拟机,通过部署该虚拟机,可以快速的部署CloudForms的环境。由于是虚拟机,根据环境的不同,可以部署在不通的虚拟化平台上,并且根据不通的虚拟化平台,由不通的虚拟机提供,如VMware平台,RHEV平台,OpenStack平台等。本文以部署在KVM为例,讲述CloudForms Egine的部署。


2. 通过KVM部署CloudForms

  1. 建立和修改虚拟机的配置文件

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

修改如下内容:

a、名字        <name>cfme</name>

b、uuid        <uuid>ba845a90-8670-4b89-9451-3a111372950c</uuid>    通过uuidgen生成一个新的号码

c、内存        <memory unit='KiB'>4194304</memory>

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

e、启动顺序    <boot dev='hd'/>

f、磁盘文件

<disk type='file' device='disk'>                                                   #磁盘类型为file
    <driver name='qemu' type='qcow2' cache='none'/>                                #驱动类型和格式
    <source file='/var/lib/libvirt/p_w_picpaths/cfme.qcow2'/>                            #磁盘文件路径,从CloudForms中解压获取
    <target dev='vda' bus='virtio'/>                                               #磁盘名字和总线类型为virtio
    <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>    @@@注意,要删除@@@,否则总线的地址会冲突
</disk>
<disk type='file' device='disk'>
    <driver name='qemu' type='qcow2' cache='none'/>
    <source file='/var/lib/libvirt/p_w_picpaths/cfme_vdb.qcow2'/>     #磁盘所在路径,后续创建
    <target dev='vdb' bus='virtio'/>                            #磁盘为vdb
</disk>

g、网卡

<interface type='network'>
    <mac address='52:54:00:00:00:0c'/>        #mac地址
    <source network='br-eth0'/>               #桥接网卡,@@注意@@@此处用的是ovs的网桥,如果KVM的网桥,请修改为br0
    <virtualport type='openvswitch'></virtualport>    #由于使用openvswitch网桥,需要添加,br0则不用
    <model type='virtio'/>
</interface>

h、VNC

<graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0'>        #用于VNC连接,防止没有图形界面
   <listen type='address' address='0.0.0.0'/>
</graphics>

修改完之后,虚拟机的配置文件内容如下:

cat /etc/libvirt/qemu/cfme.xml    
<domain type='kvm'>
  <name>cfme</name>
  <uuid>ba845a90-8670-4b89-9451-3a111372950c</uuid>

2. 获取CloudForms的虚拟机

    为了方便大家使用,我已经放置到网盘中,连接路径:网盘地址:http://pan.baidu.com/s/1hrrmtec

3. 解压CFME虚拟机

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

#将CFME文件拷贝至KVM虚拟机目录,并改名字

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

#基于磁盘镜像文件,创建backing file连接,backing file类似于Linux下的软链接,是一个只读的文件,增量的写内容,都会保存至新的文件,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. 启动虚拟机,并获取VNC的端口号

[root@foundation0 ~]# virsh create /etc/libvirt/qemu/cfme.xml        #加载到KVM域内
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的端口号,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母机的ip地址,使用该地址和VNC端口连接到虚拟机

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

5. 使用VNC客户端连接至CFME虚拟机

wKioL1aiBk2CyexwAABjBLbCoOI245.png

配置成功,界面如下,默认的username:admin,password:smartvm

wKiom1aiBp_gudIJAAEGolNdLgQ540.jpg


5. CloudForms初始化

    使用admin:smartvm登陆到系统中,可以自行初始化操作,初始化的操作包括如下内容:

wKioL1aiB-3Qa0g4AAK4e1EPNj8145.jpg

选择8,配置数据库即可,执行1生成key,选择内部internal,设置数据库区域为0,执行完之后,显示如下

wKioL1aiCQnjIhHgAAHLc7akxDs571.jpg

查看CloudForms的状态信息

wKioL1aiCV6gB5n5AAK-WKIAiiU598.jpg

6. 登陆CloudForms

输入https://10.16.1.197即可登陆至CloudForms,由于是https,所需要确认证书,确认证书之后,将会进入到CloudForms的管理界面

wKioL1aiCfWAGeaLAALbEz3AvXQ759.jpg

输入admin:smartvm即可登陆,登陆之后页面内容
