\*\*On Linux Mint. I extracted the archive tar.gz and cd into elasticsearch dir and ran ./bin/elasticsearch, \*\*

**The error message was: could not find java in the bundled jdk dir.**

**I have Open JDK already installed on my system.**

Hi Paul  
If you have already installed java. you have to set JAVA\_HOME variable.  
You can use below command to do that

```auto
export JAVA_HOME=$(dirname $(dirname $(readlink $(readlink $(which java)))))
export PATH=$PATH:$JAVA_HOME/bin

```

To confirm that you've done it correctly run this command:

```auto
echo $JAVA_HOME

```

The output off command should be something like:

```auto
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.282.b08-1.el7_9.x86_64/jre

```

First of all test these commands and run elasticsearch again:

```auto
export JAVA_HOME=$(dirname $(dirname $(readlink $(readlink $(which java)))))
export PATH=$PATH:$JAVA_HOME/bin

```

If everything's ok you can create the file and add commands to that in this directory:

```auto
 /etc/profile.d/java.sh

```

and finally, make source that:

```auto
source /etc/profile.d/java.sh

```

Even if I have Java on the PATH variable, do I have to do it again ?
