Ovirt4.3简易搭建
一、准备工作：
准备两台机器一台oVirt Engine管理节点
一台oVirt iNode计算节点
给oVirt Engine虚拟机4G内存
inode节点四个处理器2G内存
oVirt Engine可以使用克隆机器
oVirt inode可以不可以使用克隆机器需要重新装一台Centos7。
1、修改主机名
[[email protected] ~]# hostname Virt
[[email protected] ~]# bash
[[email protected] ~]# vim /etc/hostname
2、配置Centos7网络环境可以ping通www.baidu.com
使用VMnet8
[[email protected] ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736
[[email protected] ~]# /etc/init.d/network restart
3、更换阿里云yum源，先将已有的repo文件移动到bak目录下
[[email protected] ~]# yum install wget -y
[[email protected] ~]# cd /etc/yum.repos.d/
[[email protected] yum.repos.d]# ls
[[email protected] yum.repos.d]# mv abc.repo bak/（根据自身情况）
[[email protected] yum.repos.d]# mv CentOS-* bak/
[[email protected] yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo
4、关闭主机防火墙
[[email protected] ~]# systemctl stop firewalld
[[email protected] ~]# systemctl disable firewalld
二、安装oVirt引擎包
1、在开始安装oVirt之前，添加官方存储库：
[[email protected] ~]# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
[[email protected] ~]# yum update
[[email protected] ~]# yum install ovirt-engine
[[email protected] ~]# engine-setup
Configure Engine on this host (Yes, No) [Yes]:yes
Configure Image I/O Proxy on this host? (Yes, No) [Yes]:yes
Configure WebSocket Proxy on this machine? (Yes, No) [Yes]:yes
Please note: Data Warehouse is required for the engine. If you choose to not configure it on this host, you have to configure it on a remote host, and then configure the engine on this host so that it can access the database of the remote Data Warehouse host.
Configure Data Warehouse on this host (Yes, No) [Yes]:yes
Configure VM Console Proxy on this host (Yes, No) [Yes]:yes
Configure ovirt-provider-ovn (Yes, No) [Yes]:yes
Host fully qualified DNS name of this server [autodetected host name]:Virt
Setup can automatically configure the firewall on this system.
Note: automatic configuration of the firewall may overwrite current settings.
NOTICE: iptables is deprecated and will be removed in future releases
Do you want Setup to configure the firewall? (Yes, No) [Yes]:yes
Where is the DWH database located? (Local, Remote) [Local]:Local
Setup can configure the local postgresql server automatically for the DWH to run. This may conflict with existing applications.
Would you like Setup to automatically configure postgresql and create DWH database, or prefer to perform that manually? (Automatic, Manual) [Automatic]:Automatic
Where is the Engine database located? (Local, Remote) [Local]:Local
Setup can configure the local postgresql server automatically for the engine to run. This may conflict with existing applications.
Would you like Setup to automatically configure postgresql and create Engine database, or prefer to perform that manually? (Automatic, Manual) [Automatic]:Automatic
Engine admin password:[email protected]#
Confirm engine admin password:[email protected]#
Application mode (Both, Virt, Gluster) [Both]:Both
Setup can configure the default page of the web server to present the application home page. This may conflict with existing applications.
Do you wish to set the application as the default web page of the server? (Yes, No) [Yes]:Yes
Setup can configure apache to use SSL using a certificate issued from the internal CA.
Do you wish Setup to configure that, or prefer to perform that manually? (Automatic, Manual) [Automatic]:Automatic
Please choose Data Warehouse sampling scale:
(1) Basic
(2) Full
(1, 2)[1]:1
Please confirm installation settings (OK, Cancel) [OK]:OK
三、修改host文件
[[email protected] ~]# vim /etc/hosts
本机hosts文件
此时便可以访问ovirt管理页面
此时已经成功一半
四、配置oVirt inode
Ovirt Node支持两种部署方式，可由普通Linux系统安装VDSM和KVM服务组建Node节点，也可以在服务器之间安装oVirt Node定制的Linux操作系统。本次部署采用由普通Linux系统部署服务的方法。
1、准备工作
修改主机名
[[email protected] ~]# hostname inode
[[email protected] ~]# bash
[[email protected] ~]# vim /etc/hostname
配置hosts文件
[[email protected] ~]# vim /etc/hosts
修改本地hosts文件
192.168.218.131 inode
2、配置网络环境
更换yum源（具体步骤参照oVirt Engine）
关闭防火墙
selinux改为permissive
[[email protected] ~]# vim /etc/selinux/config
3、在开始安装inode之前，同样添加官方存储库：
[[email protected] ~]# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
[[email protected] ~]# yum -y install vdsm
五、安装节点主机
访问ovirt页面登录用户名使用admin
密码是安装Engine时设置的密码我这里是[email protected]#
添加数据中心
根据提示
名称根据自己喜好填写
描述、注释可以不写不影响实验
点击确定配置集群
点击配置集群
描述、注释可不写
CPU架构我这里是X86_64
其他可参照图示
配置主机
进入计算->主机选项安装主机大概需要20~30分钟左右。
总结报错原因：
一、没有关闭防火墙，更改selinux。
二、本地host文件没有写正确。
名称可凭自己喜好填写
Hostname是自己inode节点地址
密码是inode节点主机的root用户密码
配置完数据中心是不会上线的，需要接下来配置存储域
六、添加存储域
配置NFS存储
[[email protected] ~]# mkdir -pv /export/iso
该目录用于存放系统镜像
[[email protected] ~]# mkdir -pv /export/data
该目录用于存放虚拟机数据
[[email protected] ~]# chown 36:36 -R /export/
赋予VDSM权限
[[email protected] ~]# chmod 0755 -R /export/
赋予执行权限
[[email protected] ~]# vim /etc/exports
[[email protected] ~]# cat /etc/exports
[[email protected] ~]# systemctl start nfs.service
启动nfs服务
[[email protected] ~]# systemctl enable nfs.service
设置nfs服务开机自启
ovirt管理界面新建存储域
这个域用于存放镜像
这个域用于存放虚拟机数据
注意导出路径是inode节点的赋予VDSM的那个目录
然后点击确定
此时数据中心不出意外状态会变为UP
八、上传镜像文件
ovirt管理页面找到磁盘
然后右上角新建
先添加一个5G大小的磁盘
然后右上角找到上传，我这里将Winxp镜像上传
上传之前确保ovirt-imageio-proxy服务正确配置，如果配置不正确的话请重启ovirt-engine服务
重启虚拟机或者重启本机，解决该问题，上传成功之后
状态会显示为OK
九、创建虚拟机
实例镜像指定之前创建5G大小的磁盘
windows下磁盘接口更改为IDE
添加两个VM网络接口
引导选项第一个设备为CD-ROM
附加CD打对勾启用引导菜单，然后点击确定
等带虚拟机添加之后便可以开启。
十、安装控制台
控制台设置如下
点击控制台客户端资源
进入这个链接
下载这个工具
安装之后点击
便会下载.vv文件使用刚才安装好的软件打开
便会到此界面，此时表明虚拟机已经创建成功。
