1. Installation environment requirements

you need to install Storm’s dependencies on Nimbus and the worker machines. These are:

  1. Java 7+ (Apache Storm 1.x is tested through travis ci against both java 7 and java 8 JDKs)
  2. Python 2.6.6 (Python 3.x should work too, but is not tested as part of our CI enviornment)

Storm runs on Java 7+ and Python 2.6.6 +, so it needs to be pre-installed. Since the two software have dependencies in multiple frameworks, the installation steps are sorted separately as follows:

  • JDK installation in Linux

  • Python installation in Linux

2. Download and unpack it

Download and unpack, official download address: storm.apache.org/downloads.h…

#The tar ZXVF - apache - storm - 1.2.2. Tar. Gz
Copy the code

3. Configure environment variables

# vim /etc/profile
Copy the code

Add environment variables:

Export STORM_HOME = / usr/app/apache - storm - 1.2.2 export PATH = $STORM_HOME/bin: $PATHCopy the code

Make configured environment variables take effect:

# source /etc/profile
Copy the code

4. Start related processes

Because multiple processes need to be started, the background process is used to start the process. Go to ${STORM_HOME}/bin and run the following commands:

#Start the zookeeper
nohup sh storm dev-zookeeper &
#Example Start nimbus on the primary node
nohup sh storm nimbus &
#Start the supervisor of the secondary node 
nohup sh storm supervisor &
#Start UI UI  
nohup sh storm ui &
#Start log viewing service LogViewer 
nohup sh storm logviewer &
Copy the code

5. Check whether the startup is successful

Verification Method 1: JPS Viewing processes:

[root@hadoop001 app]# jps
1074 nimbus
1283 Supervisor
620 dev_zookeeper
1485 core
9630 logviewer
Copy the code

Authentication Mode 2: Access port 8080 and view the Web-UI.
