Question

$JAVA_HOME path not sourced correctly in ~/bash_profile at login?

Hi,

Upon logging into my CentOS 7 VM, my $JAVA_HOME is always set to : /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64/jre, which is incorrect.

My ~/.bash_profile reads:

.bash_profile

Get the aliases and functions

if [ -f ~/.bashrc ]; then . ~/.bashrc fi

User specific environment and startup programs

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64/jre export JAVA_HOME

PYCHARM_HOME=/opt/pycharm-community-2017.2.3/ export PYCHARM_HOME

ECLIPSE_HOME=/opt/eclipse export ECLIPSE_HOME

export SPARK_HOME=/opt/spark

PATH=$PATH:$HOME/.local/bin:$HOME/bin:$JAVA_HOME/bin:$SPARK_HOME/bin:$PYCHARM_HOME/bin:$ECLIPSE_HOME

export PATH Sourcing .bash_profile each time I open a new terminal appears to correct the issue, but why is my $JAVA_HOME path defaulting to an old version on startup and not being set to the directory specified in .bash_profile?

help me!

Try putting them in the ~/.bashrc file instead of the ~/.bash_profile file.

Basically… when you start the shell, .bashrc will be sourced at first. I think this SuperUser answer will explain the difference much better than me, as it’s a bit of longer answer.
