Logstash 7.x on raspberry pi 4

Elastic Stack Logstash

Hi all, never had any success in getting logstash 7.x installed on raspberry pi 4, is anyone able to get it running?

Below are the steps that I have taken:

root@wks:/# uname -a
Linux home-wks 4.19.57-v7l+ #1244 SMP Thu Jul 4 18:48:07 BST 2019 armv7l GNU/Linux

#prepare requisite
apt-get install openjdk-8-jdk -y
apt-get install apt-transport-https jruby -y
apt-get install texinfo build-essential ant git -y

update-alternative --config java
#choose java 8

#compile arm-linux jffi library
git clone GitHub - jnr/jffi: Java Foreign Function Interface
cd jffi/
ant jar

#download and install logstash
wget https://artifacts.elastic.co/downloads/logstash/logstash-7.3.2.deb
dpkg -i --force-all logstash-7.3.2.deb

#replace libjffi
mv /usr/share/logstash/vendor/jruby/lib/jni/arm-Linux/libjffi-1.2.so /usr/share/logstash/vendor/jruby/lib/jni/arm-Linux/libjffi-1.2.so.old
cp ~/jffi/build/jni/libjffi-1.2.so /usr/share/logstash/vendor/jruby/lib/jni/arm-Linux/libjffi-1.2.so

#enable logstash service
systemctl enable logstash
systemctl start logstash

Did you manage to fix it? I'm getting the same problem now :cry: I can't find a solution.

@wiznil I just found a solution! This simple script made it:

I have now logstash 7.3.2 running in a Raspberry Pi 4 with Buster :tada:
