CentOS5.5下搭建Eucalyptus1.6.2云平台环境
Eucalyptus支持Ubuntu 、CentOS、Debian、openSUSE四个平台,以CentOS平台为例详细说明一下完整搭建过程。

1.安装CentOS操作系统

首先下载CentOS操作系统的镜像文件，有i386和x86_64两种版本之分，i386只适合在32位机器上安装，x86_64在32位64位机器都合适安装。这里选择最新版CentOS-5.5-x86_64。官方下载地址：http://mirrors.163.com/centos/5.5/isos/x86_64/ 总共有8个镜像文件，注意是CentOS-5.5-x86_64-bin系列而非LiveCD。最简安装的话下载前两个镜像就行了。

具体安装参考附件中：CentOS_5.5_图形安装教程(超详细)。

2.依赖软件安装
Java代码
1. yum install gcc
3. yum intall ntp
5. yum install -y java-1.6.0-openjdk ant ant-nodeps dhcp bridge-utils httpd
```
yum install gcc

yum intall ntp

yum install -y java-1.6.0-openjdk ant ant-nodeps dhcp bridge-utils httpd
```
在安装Centos过程中把虚拟化选上，这样可以自动安装Xen，比较方便点。

3.配置Xen

安装完毕，进入系统

vim /etc/xen/xend-config.sxp

修改以下字段：
Java代码
1. (xend-http-server yes)
3. (xend-unix-server yes)
5. (xend-unix-path /var/lib/xend/xend-socket)
7. (xend-address localhost)
9. (network- script network-bridge)
11. (vif- script vif-bridge)
13. (dom0-min-mem 196)
15. (dom0-cpus 0)
17. (vncpasswd '')
```
(xend-http-server yes)

(xend-unix-server yes)

(xend-unix-path /var/lib/xend/xend-socket)

(xend-address localhost)

(network-    script    network-bridge)

(vif-    script    vif-bridge)

(dom0-min-mem 196)

(dom0-cpus 0)

(vncpasswd '')
```
4.配置防火墙

推荐把防火墙和Selinux关了，如果不关的话需要在防火墙上打开指定的端口
5.下载eucalyptus安装包，和euca2ool 管理工具

http://open.eucalyptus.com/downloads
分别下安装包和euca2ool包，选择你的版本
6.安装第三方软件包
Java代码
1. rpm -ivh aoetools-21-1.el4.x86_32.rpm
3. euca-axis2c-1.5.0-2.x86_32.rpm
5. euca-rampartc-1.2.0-1.x86_32.rpm
7. vblade-14-1mdv2008.1.x86_32.rpm
```
rpm -ivh aoetools-21-1.el4.x86_32.rpm

euca-axis2c-1.5.0-2.x86_32.rpm

euca-rampartc-1.2.0-1.x86_32.rpm

vblade-14-1mdv2008.1.x86_32.rpm
```
7.Eucalyptus安装
7.1.安装前端节点CC,CLC，后端数据节点NC，这里只为测试一下，所以都装在192.168.34.195上了。生产环境中是用层次的。切勿安装在一起。
Java代码
1. rpm -ivh eucalyptus-1.6.2-1.x86_32.rpm
3. eucalyptus-cloud-1.6.2-1.x86_32.rpm
5. eucalyptus-gl-1.6.2-1.x86_32.rpm
7. eucalyptus-cc-1.6.2-1.x86_32.rpm
9. eucalyptus-wc-1.6.2-1.x86_32.rpm
11. eucalyptus-sc-1.6.2-1.x86_32.rpm// 安装node controller
13. rpm -ivh eucalyptus-1.6.2-1.x86_32.rpm
15. eucalyptus-gl-1.6.2-1.x86_32.rpm
17. eucalyptus-nc-1.6.2-1.x86_32.rpm
```
rpm -ivh eucalyptus-1.6.2-1.x86_32.rpm

eucalyptus-cloud-1.6.2-1.x86_32.rpm

eucalyptus-gl-1.6.2-1.x86_32.rpm

eucalyptus-cc-1.6.2-1.x86_32.rpm

eucalyptus-wc-1.6.2-1.x86_32.rpm

eucalyptus-sc-1.6.2-1.x86_32.rpm// 安装node controller

rpm -ivh eucalyptus-1.6.2-1.x86_32.rpm

eucalyptus-gl-1.6.2-1.x86_32.rpm

eucalyptus-nc-1.6.2-1.x86_32.rpm
```
7.2.配置BRIDGE

修改/etc/sysconfig/network-scripts/ifcfg-eth0文件，内容参考如下：
Java代码
1. DEVICE=xenbr0
3. BOOTPROTO=static
5. BROADCAST=192.168.34.255
7. HWADDR=00:1A:64:E5:86:78
9. IPADDR=192.168.34.195
11. IPV6INIT=yes
13. IPV6_AUTOCONF=yes
15. NETMASK=255.255.255.0
17. NETWORK=192.168.34.0
19. GATEWAY=192.168.34.1
21. TYPE=Bridge
23. ONBOOT=yes
25. DEVICE=eth0
27. TYPE=Ethernet
29. BRIDGE=xenbr0
```
DEVICE=xenbr0

BOOTPROTO=static

BROADCAST=192.168.34.255

HWADDR=00:1A:64:E5:86:78

IPADDR=192.168.34.195

IPV6INIT=yes

IPV6_AUTOCONF=yes

NETMASK=255.255.255.0

NETWORK=192.168.34.0

GATEWAY=192.168.34.1

TYPE=Bridge

ONBOOT=yes

DEVICE=eth0

TYPE=Ethernet

BRIDGE=xenbr0
```
7.3.启动eucalyptus
Java代码
1. /etc/init.d/eucalyptus-cloud start
3. /etc/init.d/eucalytpsu-cc start
5. /etc/rc.d/init.d/eucalyptus-nc start
7. You should have at least 32 loop devices
9. Starting Eucalyptus services:
11. Enabling bridge netfiltering for eucalyptus.
13. done.
15. //出现done说明安装完成。
```
/etc/init.d/eucalyptus-cloud start

/etc/init.d/eucalytpsu-cc start

/etc/rc.d/init.d/eucalyptus-nc start

You should have at least 32 loop devices

Starting Eucalyptus services:

Enabling bridge netfiltering for eucalyptus.

done.

//出现done说明安装完成。
```
7.4.查看Xen虚拟机连接
Java代码
1. su eucalyptus -c "virsh list"
3. Id Name State
5. ----------------------------------
7. 0 Domain-0 running
```
su eucalyptus -c "virsh list"

Id Name                State

----------------------------------

0 Domain-0            running
```
说明连接成功

7.5.修改网络配置

vim /etc/eucalyptus/eucalyptus.conf
模式VNET_MODE改为SYSTEM //默认应该是这个，不需要更改，如果不是，请修改，关于其他模式这里不做叙述
7.6.注册控制器和节点
Java代码
1. euca_conf --register-walrus 192.168.34.195
3. euca_conf --register-cluster CloudTest 192.168.34.195 //IP地址前的是CLC名，自己取1个
5. euca_conf --register-sc CloudTest 192.168.34.195
7. Trying rsync to sync keys with "192.168.34.195"...The authenticity of host '192.168.34.195 (192.168.34.195)' can't be established.
9. RSA key fingerprint is ed:a3:21:20:4c:c4.
11. Are you sure you want to continue connecting (yes/no)? yes
13. Warning: Permanently added '192.168.34.195' (RSA) to the list of known hosts.
15. reverse mapping checking getaddrinfo for example.com failed - POSSIBLE BREAK-IN ATTEMPT!
17. root@192.168.34.195's password:
19. done.
21. SUCCESS: new cluster 'CloudTest' on host '192.168.34.195' successfully registered.
```
euca_conf --register-walrus 192.168.34.195

euca_conf --register-cluster CloudTest 192.168.34.195  //IP地址前的是CLC名，自己取1个

euca_conf --register-sc CloudTest 192.168.34.195

Trying rsync to sync keys with "192.168.34.195"...The authenticity of host '192.168.34.195 (192.168.34.195)' can't be established.

RSA key fingerprint is ed:a3:21:20:4c:c4.

Are you sure you want to continue connecting (yes/no)? yes

```
前端控制器注册完成

7.7.注册验证
Java代码
1. /usr/sbin/euca_conf \--list-walruses
2. registered walruses:
3. walrus 192.168.34.195 //返回的IP地址是否为你注册的IP
4. /usr/sbin/euca_conf \--list-clusters
5. registered clusters:
6. CloudServer 192.168.34.195
7. /usr/sbin/euca_conf \--list-scs
8. registered storage controllers:
```
/usr/sbin/euca_conf \--list-walruses
registered walruses:
walrus  192.168.34.195  //返回的IP地址是否为你注册的IP
/usr/sbin/euca_conf \--list-clusters
registered clusters:
CloudServer  192.168.34.195
/usr/sbin/euca_conf \--list-scs
registered storage controllers:
```
7.8.添加计算节点
Java代码
1. euca_conf -addnode 192.168.34.195
2. Trying rsync to sync keys with "192.168.34.195"...reverse mapping checking getaddrinfo for example.com failed - POSSIBLE BREAK-IN ATTEMPT!
3. root@192.168.34.195's password:
4. done.
```
euca_conf -addnode 192.168.34.195
Trying rsync to sync keys with "192.168.34.195"...reverse mapping checking getaddrinfo for example.com failed - POSSIBLE BREAK-IN ATTEMPT!
root@192.168.34.195's password: 
done.
```
7.9.验证节点
Java代码
1. euca_conf --list-nodes
3. registered nodes:
5. 192.168.34.195 CloudTest
```
euca_conf --list-nodes

registered nodes:

192.168.34.195 CloudTest
```
7.10.登入web管理界面：

至此，Eucalyptus安装配置完毕虚拟开启云端之旅.登陆Eucalyptus控制台
https://192.168.34.195:8443
默认管理帐号admin,密码admin，第一次登陆需要强制修改

一定记得要先关闭了centOS的防火墙才可正常访问到Eucalyptus的web控制台
