                          I am trying to set **JAVA_HOME** so that I can **install Apache Solr** with the help of this **tutorial **. I am connected to my server using **ssh** with **root user**

To allow the running sh script to install Apache Solr:

    mount | grep noexec

Re-mounting file system with exec option:

    mount -o remount,exec /dev/md1

Then every time I try to install it using the following commands

    bin/install_solr_service.sh /tmp/solr-5.3.1.tgz
I get the following message:

    WARNING: /opt/solr-5.3.1 already exists! Skipping extract ...
    
    Creating /etc/init.d/solr script ...
    The currently defined JAVA_HOME (/usr/local/jdk) refers
    to a location where Java could not be found.  Aborting.
    Either fix the JAVA_HOME variable or remove it from the
    environment so that the system PATH will be searched.

    Service solr installed.

This is what I tried so far:

    nano /root/.bash_profile 
    nano /etc/profile

I added the following to the files above at the end and saved them

    export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64
    export PATH=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64/bin:$PATH

That didn't work.

I created the following file /etc/profile.d/java.sh and put in it:

    export JRE_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64/jre/
    export PATH=$PATH:$JRE_HOME/bin
    
    export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64
    export JAVA_PATH=$JAVA_HOME
    
    export PATH=$PATH:$JAVA_HOME/bin

And ran the following command:

    source java.sh
That also didn't work.

I tried to run the following command:

    export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64

No luck at all.

But when a run the following commands that is what I get

    echo $JAVA_HOME
    /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64
    echo $PATH
    /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64/bin:/usr/local/jdk/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64/jre//bin:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-0.b17.el6_7.x86_64/bin:/usr/local/bin:/usr/X11R6/bin:/root/bin
