配置storm集群的过程中出现写问题，记录下来
1.storm是通过zookeeper管理的，先要安装zookeeper，从zk官网上下来，我这里下下来的的3.4.9,下载后移动到/usr/local,并解压。
tar -zxvf zookeeper-3.4.9.tar.gz
2.进入conf目录，复制zoo_sample.cfg且改名未zoo.cfg,修改zoo.cfg配置文件
cp zoo_sample.cfg /usr/local/zookeeper-3.4.9/conf/zoo.cfg
打开gedit zoo.cfg，配置：
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/tmp/zookeeper
dataLogDir=/tmp/zookeeperlogs
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=192.168.154.129:2888:3888
server.2=192.168.154.133:2888:3888
server.3=192.168.154.132:2888:3888
注意红色部分，这个dataDir 下需要建立 myid，每个myid 的目录要和 dataDir 指定的目录相同，且每个机器的myid 不同，myid的值范围是1-255.
vi myid
3. server.myid=ip:port1:port2,ip 可以是本地的ip，如果在/etc/hosts 配置，也可以用该hosts的配置来制定，port1是默认指定端口，port2备用端口。
之后配置环境变量，vim /etc/profile,将其添加到环境变量中
export ZOOKEEPER_HOME=/usr/local/zookeeper-3.4.9
配置后发送到 另外的两台机器，
scp -r /usr/local/zookeeper-3.4.9 root@192.168.154.133:/usr/local (注意文件要加-r)
输入密码后即可，和上面类似配置zoo.cfg, vi myid ，修改环境变量，创建zookeeper的日志目录。
4.启动 zk
bin/zkServer.sh start ,用jps查看 是否成功，看到有quorumPeerMain显示成功
用bin/zkCli.sh -server 192.168.154.132:2181 测试是否可以链接到另外两台。
5.安装storm
从官网下载storm,我下载的0.9.6，非最新版本，下载后解压到 /usr/local/storm目录下
tar -zxvf apache-storm-0.9.6.tar.gz
6.进入conf目录下，修改storm.yaml

注意 上面的红色部分，前面要加上空格，要不会报expected '<document start>', but found BlockMappingStart
in 'reader', line 46, column 1:
supervisor.slots.ports:
我就是这个问题折腾了好久，，经试验原来是这几个配置名称前需要加空格。即：
