Eucalyptus组件：在逻辑上，Eucalyptus云包括4个组件：
存储控制器（walrus）
云控制器(简称CLC或者“cloud”)
集群控制器(cc)
节点控制器(nc)

the front end (clc,cc,walrs,sc)
10.50.121.101
the node (nc)
10.50.121.100

1.package install
yum install -y gcc ntp java-1.6.0-openjdk ant ant-nodeps  dhcp bridge-utils \  perl-Convert-ASN1.noarch  scsi-target-utils  httpd  xen*   kernel-xen*

2.configure xen

7.post-install steps
/etc/libvirt/libvirtd.conf
unix_sock_group = "libvirt"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0770"

reboot machine

8.Start up your Eucalyptus services.
On the front-end:
/etc/init.d/eucalyptus-cloud start
/etc/init.d/eucalyptus-cc start

On the node(s):
/etc/init.d/eucalyptus-nc start

9.add home
mkdir /home/eucalyptus
chown eucalyptus.  /home/eucalyptus
chmod 700 /home/eucalyptus/

10.test install
su eucalyptus -c "virsh list"

11注册控制机以及节点
a)注册frontend节点
a1)注册walrus所在节点
euca_conf --register-walrus 10.50.121.101
a2)IP前加上自定义的CLC的名字
euca_conf --register-cluster cluster101 10.50.121.101
a3)注册storage control
euca_conf --register-sc cluster101 10.50.121.101

b)注册node节点
euca_conf --register-nodes 10.50.121.100

c)验证注册是否成功
[root@xen101 ~]# euca_conf --list-walruses
registered walruses:
   walrus  10.50.121.101
[root@xen101 ~]# euca_conf --list-clusters
registered clusters:
   cluster101  10.50.121.101
[root@xen101 ~]# euca_conf --list-scs
registered storage controllers:
   cluster101  10.50.121.101
[root@xen101 ~]# euca_conf --list-nodes
registered nodes:
   10.50.121.100  cluster101  

11.
a)login

admin/bestvwin

b)download credentials to zoness29
unzip euca2-admin-x509.zip  -d euca
mv euca  .euca
cd .euca
chmod 755 *
echo "[ -r ~/.euca/eucarc ] && ~/.euca/eucarc" >>  ~/.bashrc

download Euca2ools

tar zxvf euca2ools-$VERSION-*.tar.gz
cd euca2ools-$VERSION-*
sudo -s
yum install -y swig
rpm -Uvh python25-2.5.1-bashton1.x86_64.rpm \
python25-libs-2.5.1-bashton1.x86_64.rpm \
euca2ools-1.3.1-1.x86_64.rpm

c)安装存储镜像
download

####创建VM
首先创建密钥文件
[root@bestvpuppet ~]# euca-add-keypair mykey > mykey.private
[root@bestvpuppet ~]# chmod 0600 mykey.private
接着运行创建实例命令
euca-run-instances -k mykey emi-1CF215AE
