Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

On executing sudo ./startup.sh in CentOS, I am getting the following error:

"Neither the JAVA_HOME nor the JRE_HOME environment variable is defined"

But I have already defined it in bashrc in the following way:

export JAVA_HOME=/home/manish/New_learning/jdk1.8.0_212
export PATH=$JAVA_HOME/bin:$PATH

Please Add in

../tomcat/bin/startup.sh

script with below java parameters syntax :

JAVA_HOME=/JDK/path/

PATH=$PATH:$HOME/bin:$JAVA_HOME/bin

export PATH

export JAVA_HOME

Example

JAVA_HOME=/appl/prod/Protine/tomcat/jdk1.5.0_16/

PATH=$PATH:$HOME/bin:$JAVA_HOME/bin

export PATH

export JAVA_HOME

It's working for me , hope it will work for you too.

When you define it in your .bashrc file, it will be OK and well defined for your user.

When you launch the command with sudo, it runs as super-user/root, and NOT as your user; so your .bashrc file is 'useless' in this case.

You should update your environment with a system file like something under /etc/profile.d for instance:

sudo touch /etc/profile.d/variousPath.sh
sudo chown bsquare /etc/profile.d/variousPath.sh
cat >> /etc/profile.d/variousPath.sh <<EOF
export JAVA_HOME=/home/manish/New_learning/jdk1.8.0_212
export PATH=$JAVA_HOME/bin:$PATH
EOF

Reboot your computer, and your SYSTEM environment will know $JAVA_HOME.
