一、实验环境：

主机名 IP（Static）系统配置用途
nebula 192.168.100.216 CentOS-6.4-x86_64-minimal 2CPU,1G RAM,20G DISK,1网卡管理节点

node01 192.168.100.217 CentOS-6.4-x86_64-minimal 4CPU,32G RAM,300G DISK,2网卡计算节点

一、管理节点配置：

1.配置hosts文件

编辑/etc/hosts文件，将管理节点和计算节点IP主机名的对应关系加入其中

[root@nebula ~]# vi /etc/hosts

nebula 192.168.100.216

node01 192.168.100.217

2.关闭selinux和iptables

[root@nebula ~]# vi /etc/selinux/config

SELINUX=disabled

[root@nebula ~]# iptables –F

[root@nebula ~]# service iptables stop

[root@nebula ~]# service ip6tables stop

[root@nebula ~]# chkconfig iptables off

[root@nebula ~]# chkconfig ip6tables off

[root@nebula ~]# reboot

3.更新源，在此使用fedora源

[root@nebula ~]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@nebula ~]# rpm -ivh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

4.安装mysql数据库

[root@nebula ~]# yum -y install mysql-devel mysql-server

[root@nebula ~]# service mysqld start

[root@nebula ~]# chkconfig mysqld on

[root@nebula ~]# mysql_secure_installation

Enter current password for root (enter for none): 回车

Set root password? [Y/n] y

New password: chensh

Re-enter new password: chensh

Password updated successfully!

Remove anonymous users? [Y/n] y

Disallow root login remotely? [Y/n] y

Remove test database and access to it? [Y/n] y

Reload privilege tables now? [Y/n] y

5.创建Opennebula数据库

* MySQL的密码为chensh

[root@Master ~]# mysql -u root -p

mysql> CREATE USER 'oneadmin'@'localhost' IDENTIFIED BY 'oneadmin';

mysql> CREATE DATABASE opennebula;

mysql> GRANT ALL PRIVILEGES ON opennebula.* TO 'oneadmin' IDENTIFIED BY 'oneadmin';

mysql> FLUSH PRIVILEGES;

mysql> quit;

5.下载安装Opennebula4.2

[root@nebula ~]# wget http://dev.opennebula.org/packages/opennebula-4.2.0/CentOS-6/CentOS-6-opennebula-4.2.0-1.tar.gz

[root@nebula ~]# tar -zxvf CentOS-6-opennebula-4.2.0-1.tar.gz

[root@nebula ~]# cd opennebula-4.2.0-1

[root@nebula opennebula-4.2.0-1]# yum localinstall opennebula-4.2.0-1.x86_64.rpm opennebula-common-4.2.0-1.x86_64.rpm opennebula-flow-4.2.0-1.x86_64.rpm opennebula-gate-4.2.0-1.x86_64.rpm opennebula-java-4.2.0-1.x86_64.rpm opennebula-ozones-4.2.0-1.x86_64.rpm opennebula-ruby-4.2.0-1.x86_64.rpm opennebula-server-4.2.0-1.x86_64.rpm opennebula-sunstone-4.2.0-1.x86_64.rpm

[root@nebula opennebula-4.2.0-1]# cd context

[root@nebula context]# rpm -ivh opennebula-context-4.2.0-1.x86_64.rpm

[root@nebula context]# cd ../src

[root@nebula src]# useradd dsa

[root@nebula src]# rpm -ivh opennebula-4.2.0-1.src.rpm

11.设置.bash_profile环境变量

[root@nebula ~]# vi .bash_profile

添加：

export ONE_AUTH=/var/lib/one/.one/one_auth

[root@nebula ~]# source ~/.bash_profile

12.设置OpenNebula使用的数据库参数

[root@nebula ~]# vi /etc/one/oned.conf

# DB = [ backend = "sqlite" ]

# Sample configuration for MySQL

DB = [ backend = "mysql",

server = "localhost",

port = 0,

user = "oneadmin",

passwd = "oneadmin",

db_name = "opennebula" ]

13.设置SunStone使用的host参数

[root@nebula ~]# vi /etc/one/sunstone-server.conf

将原有:host: 127.0.0.1中IP字段修改为本机IP：

:host: 0.0.0.0

保存退出。

14.启动nebula和sunstone服务

[root@nebula ~]# one start

[root@nebula ~]# sunstone-server start

15.修改sunstone oneadmin用户密码

[root@nebula ~]# oneuser list

ID NAME GROUP AUTH VMS MEMORY CPU

0 oneadmin oneadmin core - - -

1 serveradmin oneadmin server_c - - -

[root@nebula ~]# oneuser passwd 0 password

[root@nebula ~]# echo “oneadmin:password” > /var/lib/one/.one/one_auth

二、计算节点配置：

一、管理节点配置：

1.配置hosts文件

编辑/etc/hosts文件，将管理节点和计算节点IP主机名的对应关系加入其中

[root@node01 ~]# vi /etc/hosts

nebula 192.168.100.216

node01 192.168.100.217

2.关闭selinux和iptables

[root@node01 ~]# vi /etc/selinux/config

SELINUX=disabled

[root@node01 ~]# iptables –F

[root@node01 ~]# service iptables stop

[root@node01 ~]# service ip6tables stop

[root@node01 ~]# chkconfig iptables off

[root@node01 ~]# chkconfig ip6tables off

[root@node01 ~]# reboot

3.设置桥接网络

(1).编辑/etc/sysconfig/network内容如下：

[root@node01 ~]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=node01

GATEWAY=br0

(2).编辑/etc/sysconfig/network-scripts/ifcfg-eth0内容如下,HWADDR可注释掉：

[root@node01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

ONBOOT=yes

BRIDGE=br0

(3).创建ifcfg-br0文件，内容如下：

[root@node01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-br0

DEVICE=br0

BOOTPROTO=static

ONBOOT=yes

TYPE=Bridge

IPADDR=192.168.100.217

NETMASK=255.255.255.0

GATEWAY=192.168.100.254

BROADCAST=192.168.100.255

DELAY=0

(4).重启网络服务：

[root@node01 ~]# service network restart

(5).查看网桥接口：

[root@node01 ~]# brctl show

bridge name bridge id STP enabled interfaces

br0 8000.000c29ed3d46 no eth0

virbr0 8000.525400eeaa17 yes virbr0-nic

(6).查看br0接口IP：

[root@node01 ~]# ip addr show br0

7: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN

link/ether 00:0c:29:ed:3d:46 brd ff:ff:ff:ff:ff:ff

inet 192.168.100.217/24 brd 192.168.100.255 scope global br0

inet6 fe80::20c:29ff:feed:3d46/64 scope link

valid_lft forever preferred_lft forever

(7).查看路由是否正确：

[root@node01 ~]# ip route

192.168.100.0/24 dev br0 proto kernel scope link src 192.168.100.217

192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1

169.254.0.0/16 dev br0 scope link metric 1007

default via 192.168.100.254 dev br0

(8).ping外网地址测试连通性：

[root@node01 ~]# ping www.baidu.com

PING www.a.shifen.com (61.135.169.125) 56(84) bytes of data.

64 bytes from 61.135.169.125: icmp_seq=1 ttl=128 time=62.2 ms

64 bytes from 61.135.169.125: icmp_seq=2 ttl=128 time=46.2 ms

4.创建cloud组和oneadmin用户

[root@node01 ~]# groupadd -g 1000 cloud

[root@node01 ~]# useradd -u 1000 -g cloud -m oneadmin -s /bin/bash

[root@node01 ~]# usermod -d /var/lib/one oneadmin

[root@node01 ~]# passwd oneadmin

[root@node01 ~]# chown oneadmin:cloud /var/lib/one

5.下载软件包

[root@node01 ~]# yum -y install sudo vconfig qemu-kvm qemu-kvm-tools libvirt wget

[root@node01 ~]# wget http://dev.opennebula.org/packages/opennebula-4.2.0/CentOS-6/CentOS-6-opennebula-4.2.0-1.tar.gz

6.更新源，在此使用fedora源

[root@node01 ~]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@node01 ~]# rpm -ivh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

7.安装opennebula-node-kvm

[root@node01 ~]# tar -zxvf CentOS-6-opennebula-4.2.0-1.tar.gz

[root@node01 opennebula-4.2.0-1]# yum localinstall opennebula-node-kvm-4.2.0-1.x86_64.rpm opennebula-common-4.2.0-1.x86_64.rpm

8.配置libvirtd

编辑/etc/libvirt/libvirtd.conf配置libvirt，将操作权限授予给cloud组，并将listen_tcp = 1、unix_sock_rw_perms、auth_unix_ro、auth_unix_rw的“#”注释去掉。

[root@node01 ~]# vi /etc/libvirt/libvirtd.conf

listen_tcp = 1

unix_sock_group = "cloud"

unix_sock_rw_perms = "0770"

auth_unix_ro = "none"

auth_unix_rw = "none"

编辑/etc/libvirt/qemu.conf，设置VNC：

[root@node01 ~]# vi /etc/libvirt/qemu.conf

vnc_listen = “0.0.0.0″

user = "oneadmin" /*oneadmin用户管理虚拟机*/

group = "cloud"

dynamic_ownership = 0 /*禁止虚拟镜像动态调整所有权限*/
