搭建环境介绍：

硬件平台：HP Z800 工作站内存：24GB 硬盘：1TB
虚拟化环境：XenServer 6.2.0
VM1：Ubuntu 12.04 amd64 server | IP：192.168.137.50
VM2：Ubuntu 12.04 amd64 server | IP：192.168.137.51
VM3：Ubuntu 12.04 amd64 server | IP：192.168.137.52

1、从Git安装Appscale

在Xen上安装好Ubuntu 12.04 server版本后，使用root用户登录，然后运行：

wget -O – http://bootstrap.appscale.com | sh

然后会从git clone到本地，进行自动化安装。该命令会执行下面的操作：

安装git

apt-get install -y git-core

构建appscale

cd /root
git clone git://github.com/AppScale/appscale.git
cd appscale/debian
bash appscale_build.sh

构建appscale-tools

cd /root
git clone git://github.com/AppScale/appscale-tools.git
cd appscale-tools/debian
bash appscale_build.sh

不出意外，基本可以完成自动化安装。如果报错，请Google。

2、VM准备

首先将上面安装的VM进行clone，这里使用，复制出VM1和VM2。

然后对每个VM进行设置静态IP:修改每个VM的/etc/network/interfaces文件

VM1：

1auto eth0
2iface eth0 inet static
3address 192.168.137.50
4netmask 255.255.255.0
5gateway 192.168.137.1
6dns-nameservers 114.114.114.114

VM2：

1auto eth0
2iface eth0 inet static
3address 192.168.137.51
4netmask 255.255.255.0
5gateway 192.168.137.1
6dns-nameservers 114.114.114.114

VM3：

1auto eth0
2iface eth0 inet static
3address 192.168.137.52
4netmask 255.255.255.0
5gateway 192.168.137.1
6dns-nameservers 114.114.114.114

对应也修改每个VM的主机名。（配置文件/etc/hostname）

3、准备启动

三个VM重新启动后，在master上运行：

`1`	`appscale init cluster`

初始化集群。

修改自动生成的配置文件：AppScalefile

1ips_layout :
2  master : 192.168.137.50
3  appengine : 192.168.137.50
4  database : 192.168.137.51
5  zookeeper : 192.168.137.52

4、启动集群

执行命令：

`1`	`appscale up`

看到以下输出信息：

01Starting AppScale 1.14.0 over a virtualized cluster.
02Log in to your head node: ssh -i /root/.appscale/appscale6099037d27e2439c8396c88148e5037b.key root@192.168.137.50
