本文介紹如何在 CentOS 6 上安裝 Ovirt

參考網址:
http://wiki.centos.org/zh-tw/HowTos/oVirt

版本資訊:
CentOS 6.3 x64 (安裝 Ovirt 請使用 64bit)

系統需求:
硬體:
最少：擁有 4GB 記憶體的雙核伺服器、25 GB 磁碟空間及 1 Gbps 網絡介面。
建議：擁有 16GB 記憶體的雙插座／四核伺服器、橫跨多個轉軸的 50GB 磁碟空間及 1 Gbps 網絡介面。
引擎並不需要 CPU 提供虛擬化延伸。

管理存取:
之後會透過瀏覽器來設定，建議這台就專作 Ovirt 使用，避免其他不必要的問題


網路:
DHCP: 個人覺得可有可無，都設定固定IP即可
DNS: 之後的架構會與 AD 作整合，因此此部分可使用 AD 取代，另外要注意 DNS 需要能正反解，不然有些功能會無法使用。
Ovirt 主機上若有安裝 NetworkManager 請停用，改使用 network



設定步驟

設定 Ovirt yum 套件
[root@OvirtM-1 ~]# cd /etc/yum.repos.d
[root@OvirtM-1 yum.repos.d]# wget -q http://people.centos.org/hughesjr/ovirt31/ovirt.repo


更新 yum 並重開機
[root@OvirtM-1 yum.repos.d]# yum  -y upgrade
[root@OvirtM-1 yum.repos.d]# shutdown -r now


安裝 Ovirt 套件
[root@OvirtM-1 ~]# yum -y install ovirt-engine


Ovirt 初始設定
[root@OvirtM-1 ~]# engine-setup
Welcome to oVirt Engine setup utility

In order to proceed the installer must stop the ovirt-engine service
Would you like to stop the ovirt-engine service? (yes|no): yes
是否要停止 ovirt-engine，請輸入 yes

 oVirt Engine uses httpd to proxy requests to the application server.
It looks like the httpd installed locally is being actively used.
The installer can override current configuration .
Alternatively you can use JBoss directly (on ports higher than 1024)
Do you wish to override current httpd configuration and restart the service? ['yes'| 'no']  [yes] : yes
是否要複寫設定並重啟 httpd ，請輸入 yes

HTTP Port  [80] : 80
請輸入 HTTP 的 Port

HTTPS Port  [443] : 443
請輸入 HTTPS 的 Port

Host fully qualified domain name. Note: this name should be fully resolvable  [OvirtM-1] : OvirtM-1.example.com
輸入 Ovirt 主機名稱

The IP 192.168.1.221 does not hold a PTR record for the FQDN: OvirtM-1.example.com
User input failed validation, do you still wish to use it? (yes|no): yes
輸入的名稱必須要能正反解，但有時好像會怪怪的，輸入 yes (確定在DNS設定正確)


Enter a password for an internal oVirt Engine administrator user (admin@internal) :
輸入管理介面 admin 的密碼
Warning: Weak Password.
Confirm password :
再輸入一次

Organization Name for the Certificate  [OvirtM-1] : Example
憑證的組織名稱

The default storage type you will be using  ['NFS'| 'FC'| 'ISCSI'| 'POSIXFS']  [NFS] :
預設的 storage 要使用哪一種，預設為 NFS

Enter DB type for installation ['remote'| 'local']  [local] :
使用遠端或本地DB，預設為本地

Enter a password for a local oVirt Engine DB admin user (engine) :
輸入DB的密碼

Warning: Weak Password.
Confirm password :
再輸入一次

Configure NFS share on this server to be used as an ISO Domain? ['yes'| 'no']  [yes] :
是否要設定 ISO Domain

Local ISO domain path  [/var/lib/exports/iso] : /exports/iso
ISO Domain 的路徑

Firewall ports need to be opened.
The installer can configure iptables automatically overriding the current configuration. The old configuration will be backed up.
Alternately you can configure the firewall later using an example iptables file found under /etc/ovirt-engine/iptables.example
Configure iptables ? ['yes'| 'no']: no
是否要設定 iptables，請輸入 no

oVirt Engine will be installed using the following configuration:
=================================================================
override-httpd-config:         yes
http-port:                     80
https-port:                    443
host-fqdn:                     OvirtM-1.example.com
auth-pass:                     ********
org-name:                      Example
default-dc-type:               NFS
db-remote-install:             local
db-local-pass:                 ********
nfs-mp:                        /exports/iso
config-nfs:                    yes
override-iptables:             no
Proceed with the configuration listed above? (yes|no): yes

列出設定值，會問你是否要修改設定，輸入 yes 便開始設定

**** To access oVirt Engine browse to http://OvirtM-1.example.com:80 ****

Additional information:
 * There are less than 4096 MBs of available free memory on this machine.
It is  recommended to have at least 4096 MBs of available memory to run the oVirt Engine.
 * oVirt Engine CA SSL Certificate SHA1 fingerprint: 2C:1A:16:24:C5:E5:E9:16:2C:72:E2:91:6B:3F:02:EA:A8:64:9A:EF
 * SSH Public key fingerprint: bd:db:67:f7:c3:82:e4:f8:f3:1a:ab:3b:f9:25:1b:75
 * A default ISO share has been created on this host.
   If IP based access restrictions are required, please edit /exports/iso entry in /etc/exports
 * oVirt Engine requires the following TCP/IP Incoming ports to be opened on the firewall:
22, 80, 443
 * an example of the required configuration for iptables can be found at: /etc/ovirt-engine/iptables.example
 * The installation log file is available at: /var/log/ovirt-engine/engine-setup_2013_02_14_22_49_46.log
 * Please use the user "admin" and password specified in order to login into oVirt Engine
 * To configure additional users, first configure authentication domains using the 'engine-manage-domains' utility


修正旋轉替換日誌的問題。
sed -i 's/`;/ 2>\/dev\/null`;/' /usr/share/ovirt-engine/scripts/ovirtlogrot.sh


至此，Ovirt 便安裝完成。
