系统是osx

最近在学习spark, 有了docker搭建集群太方便了

安装好docker之后,在vbox里面做一个共享目录, 方便虚拟机从host拷贝文件

运行docker, 

接着运行
boot2docker ssh

这样就进到虚拟机里面了, 因为需要用到github上的脚本, 可以拷贝你的ssh文件到虚拟机里面

cp /Users/name/.ssh/id_* ~/.ssh/

接着输入
tce-ab

输入s输入python.tcz
输入esc键  然后 输入 i 安装python

同样的还需要安装bash.tcz ,方法同上


接着就clone amplab的docker脚本了

git clone git@github.com:amplab/docker-scripts.git

注意: 这些更改到你退出虚拟机后不会被保存下来,  记得提出虚拟机前,在mac中再运行下boot2docker save

ok,现在进到docker-scripts

进入apache-hadoop-hdfs-precise  dnsmasq-precise spark-1.0.0这3个目录,运行里面的build脚本,

运行docker images,就能看到相应的images

你需要修改deploy/start_spark_cluster.sh 的start_master方法, 加入-p 8080:8080, 这是做端口映射,将容器的8080端口暴露给虚拟机,然后你在外部可以
访问虚拟机,这样你在浏览器中可以看到集群的运行状态

work也要做端口映射, 8080给了master,8081 8082给work1 work2,依次类推
具体修改如下图所示:



接着就可以启动集群了,运行 sudo ./deploy/deploy.sh -i spark:1.0.0 -w 3

to enable cluster name resolution add the following line to _the top_ of your host's /etc/resolv.conf:
nameserver 172.17.0.23

运行docker ps:

在ports列可以看到相应的端口都做了映射

在外部运行boot2docker ip 可以看到虚拟机的ip,我这边是
bash-3.2$ boot2docker ip

The VM's Host only interface IP address is: 192.168.59.103

接着打开浏览器,依次输入 
192.168.59.103:8080  查看master状态
192.168.59.103：8081 查看work1状态
192.168.59.103：8082 查看work2状态
...

用sudo ./deploy/kill_all.sh spark可以关闭集群
