Manual install of the Java JRE

Today I had to install the Java JRE on a server to be able to use ElasticSearch. Unfortunately I couldn’t install any software that allowed me to extract and run the tar.gz file on the server.

Here is my workaround:

Download and extract

  • Start by downloading the Java 8 Server JRE.
  • Once downloaded, unzip the tar.gz file. You’ll get a tar file.
  • That tar file should be unzipped again. The output of this second unzip operation was a set of binaries and executables.
  • Copy these files over to a file share on the target server.

Installation

  • Create a folder C:\Program Files\Oracle Java Server on your server.
  • Browse to the content of the file share.  Go one level deeper e.g. jdk1.8.0_XX (where XX is the current update version) and copy this content to the new folder on your server.

Set JAVA_HOME environment variable

Finally we need to set an environment variable to point to our new Java installation:

  • Open the System Properties.
  • Click the Advanced tab and the Environment Variables button.
  • Click New... at the System Variables.
  • Use JAVA_HOME as the name of the variable and the path C:\Program Files\Oracle Java Server as the value.
  • Finish this job by clicking OK until your are back at the control panel.

That’s it!
