This guide describes the recommended way to install Graylog on SUSE Linux Enterprise Server 13 and 15. All links and packages are present at the time of writing.
Prerequisites
Graylog 5.0 requires the following to maintain compatibility with its software dependencies:
- OpenJDK 17 (This is embedded in Graylog 5.0 and does not need to be separately installed.)
- OpenSearch 1.x, 2.x (or Elasticsearch 7.10.2)
- MongoDB 5.x or 6.x
Additionally, the following patterns are required for a minimal setup (see SUSE 15 SP3 Deployment Guide):
- Base System
- Minimal System (Appliances)
- YaST configuration packages
MongoDB
Installing MongoDB on SUSE should follow the tutorial for SUSE from the MongoDB documentation. Graylog 5.0 is compatible with MongoDB 5.x-6.x.
1. Import the MongoDB public key.
sudo rpm --import https://www.mongodb.org/static/pgp/server-6.0.asc
2. Add the MongoDB repository.
sudo zypper addrepo --gpgcheck "https://repo.mongodb.org/zypper/suse/15/mongodb-org/6.0/x86_64/" mongodb
3. Install the MongoDB packages.
sudo zypper -n install mongodb-org
4. Then, start the MongoDB instance.
sudo systemctl daemon-reload
sudo systemctl start mongod.service
5. In order to automatically start MongoDB on system boot, you have to activate the MongoDB service by running the following command:
sudo systemctl enable mongod.service
OpenSearch
If you are using OpenSearch as your data node, then follow the steps below to install OpenSearch 2.5.0.
1. You may prefer to disable transparent hugepages to improve performance before installing:
sudo su
cat > /etc/systemd/system/disable-transparent-huge-pages.service <<EOF
Description=Disable Transparent Huge Pages (THP)
DefaultDependencies=no
After=sysinit.target local-fs.target
[Service]
Type=oneshot
ExecStart=/bin/sh -c 'echo never | tee /sys/kernel/mm/transparent_hugepage/enabled > /dev/null'
[Install]
WantedBy=basic.target
EOF
sudo systemctl daemon-reload
sudo systemctl enable disable-transparent-huge-pages.service
sudo systemctl start disable-transparent-huge-pages.service
2. Install the OpenSearch GPG key:
sudo rpm --import https://artifacts.opensearch.org/publickeys/opensearch.pgp
3. Download the OpenSearch 2.5.0 package:
wget https://artifacts.opensearch.org/releases/bundle/opensearch/2.5.0/opensearch-2.5.0-linux-x64.rpm
4. From the CLI, you can install the package.
sudo curl -SL https://artifacts.opensearch.org/releases/bundle/opensearch/2.x/opensearch-2.x.repo -o /etc/zypp/repos.d/opensearch-2.x.repo
sudo zypper update
sudo zypper install opensearch
5. For rpm x64.
sudo rpm -ivh opensearch-2.5.0-linux-x64.rpm
6. Edit the opensearch.yml
file:
sudo nano /etc/opensearch/opensearch.yml
7. At a minimum the following changes are required (for a single instance install):
cluster.name:
path.data: /var/lib/opensearch
path.logs: /var/log/opensearch
action.auto_create_index: false
plugins.security.disabled: true
network.host: 0.0.0.0
discovery.type: single-node
8. After the installation succeeds, enable the OpenSearch service:
sudo systemctl daemon-reload
sudo systemctl enable opensearch.service
sudo systemctl start opensearch.service
9. Then, enable and start OpenSearch:
sudo systemctl start opensearch
10. Finally, verify that OpenSearch launched correctly:
sudo systemctl status opensearch
Elasticsearch
Elasticsearch 7.10.2 is the only version that is compatible with Graylog 5.0; however, we recommend OpenSearch for new Graylog cluster installations.
The following commands will begin the installation of the open-source version of Elasticsearch. See the Elasticsearch install page for more detailed instructions.
1. First install the Elasticsearch GPG key with:
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
2. Then add the repository file /etc/zypp/repos.d/elasticsearch.repo
with the following contents:
echo "[elasticsearch-7.10.2]
name=Elasticsearch repository for 7.10.2 packages
baseurl=https://artifacts.elastic.co/packages/oss-7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md" | sudo tee /etc/zypp/repos.d/elasticsearch.repo
3. Install the 7.10.2 release with:
sudo zypper install elasticsearch-oss
Graylog Configuration for Elasticsearch
1. Make sure to modify the Elasticsearch configuration file (/etc/elasticsearch/elasticsearch.yml
), set the cluster name to Graylog
, and uncomment action.auto_create_index: false
to enable the action:
sudo tee -a /etc/elasticsearch/elasticsearch.yml > /dev/null <<EOT
cluster.name: graylog
action.auto_create_index: false
EOT
2. In order to automatically start Elasticsearch on system boot, you must activate the Elasticsearch service by running the following commands:
sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service
sudo systemctl start elasticsearch.service
Graylog
1. First install the Graylog GPG key with:
rpm --import https://packages.graylog2.org/repo/debian/keyring.gpg
2. Then add the repository file /etc/zypp/repos.d/graylog.repo
with the following content:
[graylog]
name=graylog
baseurl=https://packages.graylog2.org/repo/el/stable/5.0/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-graylog
3. After that, install the latest Graylog Open release with:
sudo zypper install graylog-server
If you are installing Graylog Operations, then you will use the following command:
sudo zypper install graylog-enterprise
Edit the Configuration File
Make sure to follow the instructions in your /etc/graylog/server/server.conf
and add password_secret
and root_password_sha2
. These settings are mandatory and, without them, Graylog will not start!
1. You can use the following command to create your password_secret
:
cat /dev/urandom | base64 | cut -c1-96 | head -1
2. You will then need to use the following command to create your root_password_sha2
:
echo -n "Enter Password: " && head -1 </dev/stdin | tr -d '\n' | sha256sum | cut -d" " -f1
3. To be able to connect to Graylog, set http_bind_address
to the public host name or a public IP address of the machine with which you can connect. More information about these settings can be found in Configuring the web interface.
4. The last step is to enable Graylog during the operating system’s startup:
sudo systemctl daemon-reload
sudo systemctl enable graylog-server.service
sudo systemctl start graylog-server.service
Now you can ingest messages into your new Graylog Cluster and extract the messages with extractors or use pipelines to work with the messages.
Cluster Setup
If you plan to have multiple servers assuming different roles in your cluster like we have in this big production setup you need to modify only a few settings. This is covered in our multi-node setup guide. The default file location guide lists the locations of the files you need to modify.
