Chapter 5. Configuring the JAVA_HOME environment variable on RHEL

Procedure

1. Set the value of JAVA_HOME.

   Copy to Clipboard Toggle word wrap

   $ export JAVA_HOME=/opt/jdk/11

2. Verify that JAVA_HOME is set correctly.

   Copy to Clipboard Toggle word wrap

   $ printenv | grep JAVA_HOME
   JAVA_HOME=/opt/jdk/11

   Note

   You can make the value of JAVA_HOME persistent by exporting the environment variable in ~/.bashrc for single users or /etc/bashrc for system-wide settings. Persistent means that if you close your terminal or reboot your computer, you do not need to reset a value for the JAVA_HOME environment variable.

   The following example demonstrates using a text editor to enter commands for exporting JAVA_HOME in ~/.bashrc for a single user:

   Copy to Clipboard Toggle word wrap

   > vi ~/.bash_profile
   
   export JAVA_HOME=/opt/jdk/11
   export PATH="$JAVA_HOME/bin:$PATH"
