7、linux 上安装storm

1.基本信息

版本	1.0.2
安装机器	三台机器
账号	hadoop
源路径	/opt/software/apache-storm-1.0.2.tar.gz
目标路径	/opt/storm -> /opt/apache-storm-1.0.2/
依赖关系	无

2.安装过程

1).使用hadoop账号解压：

[root@bgs-5p173-wangwenting opt]# su hadoop

[hadoop@bgs-5p173-wangwenting opt]$ cd /opt/software

[hadoop@bgs-5p173-wangwenting software]$ tar -zxvf /opt/software/apache-storm-${version}tar.gz -C /opt

[hadoop@bgs-5p173-wangwenting software]$ cd /opt

[hadoop@bgs-5p173-wangwenting opt]$ ln -s /opt/apache-storm-${version}/ /opt/storm

2).修改环境变量，并使其生效：

[hadoop@bgs-5p173-wangwenting hadoop]$ vim /etc/profile

添加下面的内容：

export STORM_HOME=/opt/storm

export PATH=${STORM_HOME}/bin:$PATH

使环境变量生效：

[hadoop@bgs-5p173-wangwenting hadoop]$ source /etc/profile

3).修改配置文件storm.yaml

[hadoop@bgs-5p173-wangwenting opt]$ cd /opt/storm/

[hadoop@bgs-5p173-wangwenting storm]$ vim conf/storm.yaml

 storm.zookeeper.servers:

     - "172.24.5.173"

     - "172.24.5.174"

     - "172.24.5.175"

 storm.local.dir: "/opt/storm/local"

 nimbus.host: "172.24.5.173"

 ui.port: 10088

 

 supervisor.slots.ports:

     - 6700

     - 6701

     - 6702

     - 6703

注意：注意空格的格式问题，很容易出现空格的格式问题，其次6700以及下面的这些与左端是一个tab键的距离。

4).通过scp复制其他两台机器上，并按照第2步修改环境变量。

[hadoop@bgs-5p173-wangwenting storm]$ scp -r /opt/apache-storm-${version} hadoop@bgs-5p174-wangwenting:/opt

[hadoop@bgs-5p174-wangwenting opt]$ ln -s /opt/apache-storm-${version}/ /opt/storm

[hadoop@bgs-5p173-wangwenting storm]$ scp -r /opt/hadoop/apache-storm-${version} hadoop@bgs-5p175-wangwenting software:/opt/hadoop

[hadoop@bgs-5p175-wangwenting opt]$ ln -s /opt/hadoop/apache-storm-${version}/ /opt/hadoop/storm

5).启动storm集群：

[hadoop@bgs-5p173-wangwenting storm]$ cd /opt/storm/bin

[hadoop@bgs-5p173-wangwenting bin]$ nohup ./storm nimbus &

[hadoop@bgs-5p173-wangwenting bin]$ nohup ./storm ui &

b.再在bgs-5p174-wangwenting，bgs-5p175-wangwenting机器上启动supervisor

[hadoop@bgs-5p174-wangwenting bin]$ nohup ./storm supervisor &

[hadoop@bgs-5p175-wangwenting bin]$ nohup ./storm supervisor &

6).测试网址：

http:/172.24.5.173:10088/

若能正常访问，说明启动成功
