Logstash requires Java 8. Java 9 is not supported. Use the official Oracle distribution or an open-source distribution such as OpenJDK.
To check your Java version, run the following command:
On systems with Java installed, this command produces output similar to the following:
java version "1.8.0_65" Java(TM) SE Runtime Environment (build 1.8.0_65-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
On some Linux systems, you may also need to have the
exported before attempting the install, particularly if you installed Java from
a tarball. This is because Logstash uses Java during installation to
automatically detect your environment and install the correct startup method
(SysV init scripts, Upstart, or systemd). If Logstash is unable to find the
JAVA_HOME environment variable during package installation time, you may get an
error message, and Logstash will be unable to start properly.
Installing from a Downloaded Binaryedit
Download the Logstash installation file that matches your host environment. Unpack the file. Do not install Logstash into a directory path that contains colon (:) characters.
On supported Linux operating systems, you can use a package manager to install Logstash.
Installing from Package Repositoriesedit
We also have repositories available for APT and YUM based distributions. Note that we only provide binary packages, but no source packages, as the packages are created as part of the Logstash build.
We have split the Logstash package repositories by version into separate urls to avoid accidental upgrades across major versions. For all 6.x.y releases use 6.x as version number.
We use the PGP key D88E42B4, Elastic’s Signing Key, with fingerprint
4609 5ACC 8548 582C 1A26 99A9 D27D 666C D88E 42B4
to sign all our packages. It is available from https://pgp.mit.edu.
Download and install the Public Signing Key:
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
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
echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list
echo method described above to add the Logstash repository. Do not
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.
sudo apt-get update and the repository is ready for use. You can install
sudo apt-get update && sudo apt-get install logstash
See Running Logstash for details about managing Logstash as a system service.
Download and install the public signing key:
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
Add the following in your
in a file with a
.repo suffix, for example
[logstash-6.x] name=Elastic repository for 6.x packages baseurl=https://artifacts.elastic.co/packages/6.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md
And your repository is ready for use. You can install it with:
sudo yum install logstash
The repositories do not work with older rpm based distributions that still use RPM v3, like CentOS5.
See the Running Logstash document for managing Logstash as a system service.
Images are available for running Logstash as a Docker container. They are available from the Elastic Docker registry.
See Running Logstash on Docker for details on how to configure and run Logstash Docker containers.
