Installing Logstash

APT

Download and install the Public Signing Key:

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elastic-keyring.gpg

You may need to install the apt-transport-https package on Debian before proceeding:

sudo apt-get install apt-transport-https

Save the repository definition to /etc/apt/sources.list.d/elastic-8.x.list:

echo "deb [signed-by=/usr/share/keyrings/elastic-keyring.gpg] https://artifacts.elastic.co/packages/8.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-8.x.list

Use the echo method described above to add the Logstash repository. Do no use add-apt-repository as it will add a deb-src entry as well, but we do not provide a source package. If you have added the deb-src entry, you will see an error like the following:
Unable to find expected entry 'main/source/Sources' in Release file (Wrong sources.list entry or malformed file)
Just delete the deb-src entry from the /etc/apt/sources.list file and the installation should work as expected.

Run sudo apt-get update and the repository is ready for use. You can install it with:

sudo apt-get update && sudo apt-get install logstash

Running Daemon

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

Running Logstash

sudo systemctl start logstash
