准备工作

准备3台机器，分别命名为：
- master
- slave1
- slave2
设置SSH使master免密码登陆slave1、slave2。
测试安装先关闭3台机器防火墙。

systemctl stop firewalld.service

安装jdk
验证python是否已安装 python –version

安装Zookeeper集群

下载zookeeper

官网：http://www.apache.org/dyn/closer.cgi/zookeeper/
放到/usr/下

tar -xzvf zookeeper-3.5.2-alpha.tar.gz
mv zookeeper-3.5.2-alpha.tar.gz /opt
cd /opt/zookeeper-3.5.2-alpha/conf
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg

内容：

tickTime=2000
dataDir=/opt/zookeeper-3.5.2-alpha/data
clientPort=2181
initLimit=5
syncLimit=2
server.0=master:2888:3888
server.1=slave1:2888:3888
server.2=slave2:2888:3888

拷贝：

scp -r /opt/zookeeper-3.5.2-alpha root@slave1:/opt/
scp -r /opt/zookeeper-3.5.2-alpha root@slave2:/opt/

在master,slave1,slave2上分别修改:

vi /opt/zookeeper-3.5.2-alpha/data/myid

内容分别为0 1 2

在slave1和slave2上运行：

cd /opt/zookeeper-3.5.2-alpha/bin
./zkServer.sh start

添加path

vi /etc/profile

ZOOKEEPER_HOME=/opt/zookeeper-3.5.2-alpha
PATH=$PATH:$ZOOKEEPER_HOME/bin

source /etc/profile

这样可以直接运行zkServer.sh start

检查运行情况

运行
/opt/zookeeper-3.5.2-alpha/bin/zkServer.sh status

问题处理

如果提示：
Error Contacting service.It is probably not running.

netstat -ptnl | grep 2181
kill -9 7388(用上面命令显示结果的实际端口号）
zkServer.sh stop
zkServer.sh start

安装Storm

安装依赖库

yum install libtool
yum install gcc
yum install gcc-c++
yum install make
yum install uuid-devel
yum install libuuid-devel
yum install e2fsprogs-devel

下载libsodium

wget https://download.libsodium.org/libsodium/releases/libsodium-1.0.10.tar.gz
tar -xzvf libsodium-1.0.11.tar.gz
./autogen.sh
./configure
make 
make install

ZeroMQ4.1.4

cd /opt/
wget https://ia800405.us.archive.org/21/items/zeromq_4.1.4/zeromq-4.1.4.tar.gz
tar -xzf zeromq-4.1.4.tar.gz
cd zeromq-4.1.4
# 下面这一句不要执行，在这里备用
# ./configure --with-libsodium=/opt/libsodium-1.0.11 --with-libsodium-include-dir=/opt/libsodium-1.0.11/src/libsodium/include --with-libsodium-lib-dir=/usr/lib64
./autogen.sh
./configure PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
make
sudo make install

如果提示uuid找不到，则

sudo yum install e2fsprogsl  -b current
sudo yum install e2fsprogs-devel  -b current

jzmq

git clone git://github.com/zeromq/jzmq.git
./autogen.sh
./configure

下载storm

http://storm.apache.org/downloads.html

wget "http://apache.opencas.org/storm/apache-storm-1.0.0/apache-storm-1.0.0.tar.gz"
tar -xzvf apache-storm-1.0.0.tar.gz
mv apache-storm-1.0.0 /opt
rm apache-storm-1.0.0.tar.gz
cd /opt/apache-storm-1.0.0

修改storm.yaml

cd /opt/apache-storm-1.0.0/conf
vi storm.yaml

内容：

storm.zookeeper.servers:
    - "master"     - "slave1"     - "slave2" 
storm.local.dir: "/opt/apache-storm-1.0.0/data"

nimbus.seeds: ["master"]

拷贝:

scp -r apache-storm-1.0.0 root@slave1:/opt
scp -r apache-storm-1.0.0 root@slave2:/opt

启动：
主控结点：

/opt/apache-storm-1.0.0/bin/storm nimbus &

工作结点：

/opt/apache-storm-1.0.0/bin/storm supervisor &

启动管理界面

主控结点上运行：

/opt/apache-storm-1.0.0/bin/storm ui
