Storm安装部署

1、修改/etc/hosts

172.16.3.7      nimbus
172.16.3.8      supervisor1
172.16.3.9      supervisor2
172.16.3.10     supervisor3

2、集群所有机器安装ZooKeeper,storm需要zk存储数据及进行nimbus、supervisor之间协调

   tar xzvf zookeeper-3.4.3.tar.gz

   mv zookeeper-3.4.3 ~/platform/zookeeper

   cp ~/platform/zookeeper/conf/zoo_sample.cfg ~/platform/zookeeper/conf/zoo.cfg (用zoo_sample.cfg制作$ZOOKEEPER_HOME/conf/zoo.cfg)

   配置zoo.cfg:     

     # 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.
     dataDir=/home/jjt/platform/zookeeper/data
     dataLogDir=/home/jjt/platform/zookeeper/log
     # the port at which the clients will connect
     clientPort=2181
     server.0=nimbus:2888:3888
     server.1=supervisor1:2888:3888
     server.2=supervisor2:2888:3888

     server.3=supervisor3:2888:3888

    修改zk id, 每台机器不同，cluster的echo是0，supervisor1的echo是1，supervisor2的echo是2,supervisor3的echo是3

      echo 0 > /home/pplive/platform/zookeeper/data/myid

    添加环境变量：   

          export ZOOKEEPER_HOME=/home/pplive/platform/zookeeper

          export PATH=$PATH:$ZOOKEEPER_HOME/bin

    启动zk：  zkServer.sh start

3、每台安装zeromq, storm使用zeromq进行消息同学

• # wget http://download.zeromq.org/zeromq-2.2.0.tar.gz
• # tar zxf zeromq-2.2.0.tar.gz
• # cd zeromq-2.2.0 
• # ./configure --prefix=/home/jjt/platform/zeromq
• # make
• # make install
• # sudo ldconfig (更新LD_LIBRARY_PATH)

     configure中可能会遇到的问题：

     configure:error:in '/usr/local/download/zeromq-2.2.0':

     congifure:error:no acceptable C compiler found in $PATH

     这是因为没有安装C编译器, 解决方法是：# yum install gcc*

     Error:cannot link with -luuid, install uuid-dev

     这是因为没有安装uuid相关的package,

     解决方法是：# yum install uuid*

                 # yum install e2fsprogs*

                 # yum install libuuid*

4、每台安装jzmq, zeromq依赖jzmq

• # https://github.com/nathanmarz/jzmq 下载jzmq-master.zip
• # cd jzmq-master
• # ./autogen.sh
• # ./configure --prefix=/home/pplive/platform/jzmq
• # make
• # make install

    ./autogen.sh如果报错：autogen.sh:error:could not find libtool is required to run autogen.sh，这是因为缺少了libtool，可以用#yum install libtool*来解决

5、每台安装python，storm启动脚本是python script

• # wget http://www.python.org/ftp/python/2.7.2/Python-2.7.2.tgz
• # tar zxvf Python-2.7.2.tgz
• # cd Python-2.7.2
• # ./configure
• # make
• # make install
• # vi /etc/ld.so.conf

         追加/usr/local/lib/ 

• # sudo ldconfig
• # Python 查看python是否安装正确

6、每台安装storm

     unzip storm-0.8.1.zip

     mv storm-0.8.1 ~/platform/storm

     修改storm配置 ~/platform/storm/conf/storm.yaml    

     storm.zookeeper.servers:
       - "nimbus"
       - "supervisor1"
       - "supervisor2"

       - "supervisor3"

     storm.zookeeper.port: 2181
     storm.local.dir: "/home/jjt/platform/storm/data"
     java.library.path: /usr/local/lib:/opt/local/lib:/usr/lib:/home/jjt/platform/jzmq/lib:/home/jjt/platform/zeromq/lib​
     nimbus.host: "nimbus"
     supervisor.slots.ports:
      - 6700
      - 6701
      - 6702

      - 6703

     注意yaml文件key/value之间有一个空格， 当然也可以修改log4j配置log格式

     添加环境变量：

       export STORM_HOME=/home/pplive/platform/strom

       export PATH=$PATH:$STORM_HOME/bin

     启动storm:

        storm nimubs & (nimbus上)

        storm ui & (nimbus上，可通过 http://{NimbusHost}:8080 查看topo运行状态 )

        storm supervisor( supervisor上）

至此storm 安装基本完成，可storm启动脚本提供的Option对topo进行控制，比如storm list/kill, 然而在supervisor上执行storm脚本会遇到以下错误：

       Exception in thread "main" org.apache.thrift7.transport.TTransportException: java.net.ConnectException: Connection refused
        at org.apache.thrift7.transport.TSocket.open(TSocket.java:183)
        at org.apache.thrift7.transport.TFramedTransport.open(TFramedTransport.java:81)
        at backtype.storm.thrift$nimbus_client_and_conn.invoke(thrift.clj:56)
        at backtype.storm.command.list$_main.invoke(list.clj:7)
        at clojure.lang.AFn.applyToHelper(AFn.java:159)
        at clojure.lang.AFn.applyTo(AFn.java:151)
        at backtype.storm.command.list.main(Unknown Source)

       此时需要在supervisor上将storm配置文件storm.yaml 拷贝至 ~/.storm目录下

由于storm运行中的状态保存在zk中，因此在使用过程中可以重启nimbus/supervisor而不用重启topology, 有时会因为zk中保存有文件相关状态而实际文件已不存在导致nimbus/supervisor启动失败，此时可在zk中将storm相关数据删掉，然后重启zk、storm解决。
