Apache NiFi - Environment Setup
In this chapter, we will learn about the environment setup of Apache NiFi. The steps for installation of Apache NiFi are as follows −
Setup Java Development Kit (JDK)
You can download the latest version of SDK from Oracle's Java site − Java SE Downloads. You will find instructions for installing JDK in downloaded files, follow the given instructions to install and configure the setup. Finally set PATH and JAVA_HOME environment variables to refer to the directory that contains java and javac, typically java_install_dir/bin and java_install_dir respectively.
If you are running Windows and have installed the JDK in C:\jdk-24, you would have to put the following line in your C:\autoexec.bat file.
set PATH=C:\jdk-24;%PATH% set JAVA_HOME=C:\jdk-24
Alternatively, on Windows NT/2000/XP, you will have to right-click on My Computer, select Properties → Advanced → Environment Variables. Then, you will have to update the PATH value and click the OK button.
On Unix (Solaris, Linux, etc.), if the SDK is installed in /usr/local/jdk-24 and you use the C shell, you will have to put the following into your .cshrc file.
setenv PATH /usr/local/jdk-24/bin:$PATH setenv JAVA_HOME /usr/local/jdk-24
