Question

I’ve created a file /etc/profile.d/java.sh that includes (among other things) the line of code: export JAVA_HOME=/usr/java/jdk1.6.0_30. However, when I log in via SSH or reboot the linux Centos 6.2 server, I always see:

[root@host3 /etc/profile.d]# echo $JAVA_HOME
/usr/local/jdk

This is a new installation and server, so there’s not much else done. It seems that the java.sh file is executing upon reboot or SSH login, however, the value of JAVA_HOME is being overwritten by the default value of /usr/local/jdk somehow. There isn’t even a directory jdk under /usr/local.

Any idea how to correct this? The value of JAVA_HOME needs to be set (as done in java.sh) for all users.

UPDATE 1:

I checked the /etc/profile file and searched for the text jdk as well as JAVA and neither were found. I also checked the /root/.bash_profile and it shows as follows:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

Also, if I source java.sh, everything gets set correctly. But if I reboot server, JAVA_HOME goes back to /usr/local/jdk.

Check the /etc/profile file or the .bash_profile/.profile in your home directory.
