软硬件基础信息

机子配置信息
操做系统：CentOS release 6.5 (Final)
cpu：Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz
内存：32G
磁盘大小：1.5T
storm 软件包
apache-storm-1.0.0.tar.gz
Python 版本
Centos 6.5 系统自带有以下版本 Python，知足 storm 部署的要求
Python 2.6.6 (r266:84292, Nov 22 2013, 12:16:22)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
JDK
storm1.0.0 官方要求 JDK1.7 及以上，本次实验使用 JDK1.8
java version "1.8.0_91"
zookeeper 版本
zookeeper-3.4.9.tar.gzhtml

分配机子职能

因为机子数量不足，一台机子可能有多个职能。
zookeeper
172.24.132.173
172.24.132.143
172.24.132.142
nimbus
172.24.132.174
supbervisor
172.24.132.143
172.24.132.142java

主机名与 IP 的映射

编辑各个机子的 /etc/hosts 文件，将主机名称与 IP 的对应关系加上，例如：linux

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.24.132.142  CLTQ-132-142

配置 jdk

用文本编辑器打开/etc/profile
在profile文件末尾加入：

export JAVA_HOME=/usr/local/lifecycle/jdk1.8.0_91
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

source /etc/profile 使修改生效

注意点：git

你要将 /usr/local/lifecycle/jdk1.8.0_91 改成本机 jdk安装目录
linux下用冒号 : 来分隔路径
CLASSPATH中当前目录 . 不能丢,把当前目录丢掉也是常见的错误。
export是把这三个变量导出为全局变量。
大小写必须严格区分。

安装 zookeeper 集群

zookeeper-3.4.9.tar.gz 解压到：/usr/local/github

sudo tar -C /usr/local -xzf zookeeper-3.4.9.tar.gz

配置 zookeeper 的环境变量(可选)

配置 zookeeper 的环境变量，这一步是可选的，配置以后可以全局使用 zookeeper 相关的命令，没有配置则须要到 zookeeper 的安装目录下执行命令
添加以下配置到 /etc/profile 文件的最后，并经过命令 source /etc/profile 命令使修改后的配置生效apache

#ZOOKEEPER
ZOOKEEPER=/usr/local/zookeeper-3.4.9
PATH=$PATH:$ZOOKEEPER/bin

修改 zookeeper 的配置文件

首先将 /usr/local/zookeeper-3.4.6/conf/zoo_sample.cfg 文件复制一份，并改名为 zoo.cfg。若是不须要配置集群，则不修改修改 zoo.cfg 文件。要配置集群，则须要将 zookeeper 集群信息经过 server 配置。api

tickTime=2000  
initLimit=10  
syncLimit=5  
dataDir=/usr/local/zookeeper-3.4.6/data
dataLogDir=/usr/local/zookeeper-3.4.6/log
clientPort=2181  
server.1=172.24.132.173:2888:3888
server.2=172.24.132.143:2888:3888
server.3=172.24.132.142:2888:3888

server.A=B：C：D：其中 A 是一个数字，表示这个是第几号服务器；B 是这个服务器的 ip 地址；C 表示的是这个服务器与集群中的 Leader 服务器交换信息的端口；D 表示的是万一集群中的 Leader 服务器挂了，须要一个端口来从新进行选举，选出一个新的 Leader，而这个端口就是用来执行选举时服务器相互通讯的端口。若是是伪集群的配置方式，因为 B 都是同样，因此不一样的 zookeeper 实例通讯端口号不能同样，因此要给它们分配不一样的端口号。服务器

根据 dataDir 和 dataLogDir 变量建立相应的目录，建议优先建立，由于有可能使用的 linux 帐户权限不足，zookeeper 没法自动建立这几个目录。session

建立 myid 文件

在配置文件 zoo.cfg 中 dataDir 所指路径 /usr/local/zookeeper-3.4.6/data 下，新建 myid 文件，并写入 zoo.cfg 文件的 server.A 中 A 的数值，在不一样机器上的该文件中填写相应的值。本次部署中，172.24.132.142 的 myid 文件应该写入数值 3；172.24.132.143 的 myid 文件应该写入数值 2；172.24.132.173 的 myid 文件应该写入数值 1dom

启动 zookeeper

执行命令 zkServer.sh start 将会启动 zookeeper。而执行命令 zkServer.sh stop 将会中止 zookeeper。

经过 jps 命令，能够看到 zookeeper 的进程名：QuorumPeerMain。以及执行命令 zkServer.sh status 查看 zookeeper 集群状态，以下所示：

#172.24.132.142
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg  
Mode: follower  

#172.24.132.143
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg
Mode: leader  

#172.24.132.173  
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg  
Mode: follower

能够忽略的异常信息

zookeeper 集群逐台启动的过程当中，查阅 zookeeper.out，会有以下异常：

2017-06-12 19:58:04,289 [myid:3] - WARN  [WorkerSender[myid=3]:QuorumCnxManager@400] - Cannot open channel to 1 at election address CLTQ-132-173/172.24.132.173:3888

上述异常能够忽略，由于集群环境中某些子节点尚未启动 zookeeper

验证 zookeeper 集群

AUOK

先安装 nc：

yum install -y nc

返回 imok 则代表机子的状态是正常的

echo ruok | nc 172.24.132.143 2181
imok

zookeeper 客户端

bin/zkCli.sh -server 172.24.132.143:2181

若是须要一次性链接 zookeeper 集群的多台机子，则可使用以下语法：

bin/zkCli.sh -server 172.24.132.142:2181,172.24.132.173:2181,172.24.132.143:2181

输出以下结果：

storm 集群部署

apache-storm-1.0.0.tar.gz 解压到： /usr/local/：

sudo tar -C /usr/local -xzf apache-storm-1.1.0.tar.gz

修改配置

添加以下几个主要参数就能够

storm.zookeeper.servers:
    - "172.24.132.142"
    - "172.24.132.143"
    - "172.24.132.173"

storm.zookeeper.port: 2181
storm.local.dir: "/usr/local/apache-storm-1.0.0/data"

nimbus.seeds: ["172.24.132.174"]

supervisor.slots.ports:
    - 6700
    - 6701
    - 6702
    - 6703

storm.zookeeper.servers：zookeeper 集群的 IP
storm.zookeeper.port：zookeeper 集群的端口，若是不是默认端口 2181 则须要设置
nimbus.seeds：能够做为 nimbus 的机子

拷贝配置完成的软件

将配置修改完成的软件拷贝到其余机子上：

scp -r apache-storm-1.0.0 172.24.132.142:/usr/local/

启动 nimbus 和 supervisor

nimbus 与 supervisor 能够部署在同一台机子，可是建议分开，避免相互影响。
172.24.132.174 后台运行 nimbus

bin/storm nimbus >/dev/null 2>&1 &

172.24.132.142 172.24.132.143后台运行 supervisor

bin/storm supervisor >/dev/null 2>&1 &

172.24.132.174 后台运行 storm ui
storm ui 得要在 nimbus 机子上运行，不可以在 supervisor 机子上运行

bin/storm ui >/dev/null 2>&1 &

测试 storm 集群

使用 storm 自带测试例子测试，从 github 下载工程到本地：

git clone https://github.com/apache/storm.git

拉取对应版本的分支，本次部署使用分支 1.0.x-branch：

git checkout 1.0.x-branch

进入目录 storm/examples/storm-starter，打包：

mvn package

打包颇有可能失败，每每是各类的 jar 包没法下载，能够借助 IDE，将须要的依赖下载到本地。本次部署一直没法下载的 kafka-avro-serializer 1.0，能够经过以下链接直接下载，kafka-avro-serializer 1.0，下载完成的 jar 包得要放到 .m2\repository\io\confluent\kafka-avro-serializer\1.0 下。
生成目录：storm\examples\storm-starter\target，其下的 storm-starter-1.0.2.jar 能够做为测试 jar
执行命令：

bin/storm jar /usr/local/apache-storm-1.0.0/storm-starter-1.0.2.jar org.apache.storm.starter.ExclamationTopology et

et 是 topology 的名字，任意，可是不可以省略。

部署的 storm 服务器版本为 1.1.0，而提交给 storm 跑的 jar 包为：storm-starter-1.0.2.jar。版本不对应致使上面的问题。应该是 storm-core-1.1.0.jar 的代码与 storm-core-1.0.2.jar 相差较大，或者修改了通讯的协议致使。将 storm 服务器版本修改成 1.0.0 便可解决问题

有多个 supervisor 但 storm ui 上只显示一个

具体现象就是启动了多个 supervisor，单在 ui 上只显示一个（也有多是多个 supervisor 中的某几个看上去被“合并”了），kill 掉其中任意一个 supervisor，另外一个就出现。
例如本例中有两个 supervisor，172.24.132.143 和 172.24.132.142，可是经过接口请求，每次都只会显示其中的一个，可是现实的机子是交替出现的：

curl -X GET \
  http://172.24.132.174:8080/api/v1/supervisor/summary

{
    "supervisors": [
        {
            "totalMem": 3072,
            "host": "CLTQ-132-142",
            "id": "26cdf80b-394e-47e8-a82a-ea78f82e7c22",
            "uptime": "14h 16m 17s",
            "totalCpu": 400,
            "usedCpu": 0,
            "logLink": "http://CLTQ-132-142:8000/daemonlog?file=supervisor.log",
            "usedMem": 2496,
            "slotsUsed": 3,
            "version": "1.0.0",
            "slotsTotal": 4,
            "uptimeSeconds": 51377
        }
    ],
    "schedulerDisplayResource": false,
    "logviewerPort": 8000
}

解决方案：storm.yaml 文件中有配置 storm.local.dir: "/usr/local/apache-storm-1.0.0/data"，local.dir 所指目录，重启便可解决问题。缘由是因为部署时经过 linux scp 命令直接分发软件到其余机子，残留了 local.dir 的东西，而 storm 是根据 local.dir 中的某一个或一些文件计算出一个 supervisor id 的。删除 local.dir 后，会从新生成 id。

Could not find or load main class org.apache.storm.starter.ExclamationTopology

bin/storm jar /usr/local/apache-storm-1.0.0/storm-starter-1.0.2.jar org.apache.storm.starter.ExclamationTopology et

第一确保 storm-starter-1.0.2.jar 的路径是正确的；第二保证 packagename.ExclamationTopology，包名packagename 与类名 ExclamationTopology 是正确的
