Elastic Enterprise/App search installation problem on ubuntu – Debian

I’m running a vagrant box which runs ubuntu inside a vm (using Laravel Homestead box)

I’m trying to install the Elastic App-search product.

The first requirement is to install Elastic search, which i have done multiple times. I did the following steps:
https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

sudo apt-get install apt-transport-https

echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list

sudo apt-get update && sudo apt-get install elasticsearch

I’m using the systemd configuration:

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

I’m running curl localhost:9200 and everything is working.

Next I try to install elastic app search.
https://www.elastic.co/guide/en/app-search/current/installation.html#installation-self-managed.
Which doesn’t have instructions for debian systems. But it does have a .deb install file. I downloaded the file and put it in my project route.

I ran dpkg -i on the file and it seems to have installed. When I run the command to check the file location it shows this:

 dpkg -L enterprise-search

/usr/lib/systemd/system/enterprise-search.service

I’m not really sure if this is the correct location? I want it to live in the same place as my elasticsearch install, but I’m actually not sure. I did all the next steps for the install process and ran:
./usr/share/enterprise-search/bin/elasticsearch

But this gives me the error:

Could not find java in PATH

I’m very confused by this since the main elasticsearch installation works and that also needs java? Also i want it also to run with systemd auto-enable and i want it to be available with enterprise-search start / stop. Not sure how to handle that.

    I solved it by adding another version of Java, Elastichsearch has a java install build-in and not separate, so the app-search install can't reach that version. Feels very dirty but got it working!

    Looks like it’s Debian package, so it’s installable on ubuntu, but some things may differ.
    I would say you can:

    1. Just switch to using debian VM for this (here you can get vagrant for one: https://app.vagrantup.com/debian/boxes/stretch64 )
    2. Debug. From what I see that package runs elasticsearch-env before it runs itself. Java is looked for like this:
     if [ ! -z "$JAVA_HOME" ]; then
   JAVA="$JAVA_HOME/bin/java"
   JAVA_TYPE="JAVA_HOME"
 else
   if [ "$(uname -s)" = "Darwin" ]; then
     # macOS has a different structure
     JAVA="$ES_HOME/jdk.app/Contents/Home/bin/java"
   else
     JAVA="$ES_HOME/jdk/bin/java"
   fi
   JAVA_TYPE="bundled jdk"
 fi

 if [ ! -x "$JAVA" ]; then
     echo "could not find java in $JAVA_TYPE at $JAVA" >&2
     exit 1
   fi

    So I would advise to set JAVA_HOME in start script (or before running the binary), and see if that helps.
