This tutorial will guide you through the steps to install Graylog on OpenSUSE Latest. Graylog is an open-source log management and analysis tool used for centralized log collection and analysis. It helps in monitoring and handling logs from different sources.
Before starting, make sure you have the following:
Graylog requires Elasticsearch for storing and indexing log data. Follow the steps below to install Elasticsearch:
Open the terminal and update the system using the following command:
sudo zypper update
Add the Elasticsearch repository to OpenSUSE by running the following command:
sudo zypper ar https://artifacts.elastic.co/packages/oss-6.x/yum/ elasticsearch
Import the Elasticsearch public GPG key:
sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
Install Elasticsearch by running the following command:
sudo zypper install elasticsearch-oss
Configure Elasticsearch to automatically start at boot time:
sudo systemctl enable elasticsearch.service
Start Elasticsearch by running the following command:
sudo systemctl start elasticsearch.service
Verify that Elasticsearch is running by accessing the following URL in your web browser:
http://localhost:9200/
If Elasticsearch is working properly, you should see a JSON response containing information about the Elasticsearch cluster.
Follow the steps below to install Graylog:
Add the Graylog repository to OpenSUSE by running the following command:
sudo zypper ar https://packages.graylog2.org/repo/packages/graylog-4.2-repository_latest.rpm graylog
Import the Graylog GPG public key:
sudo rpm --import https://packages.graylog2.org/repo/packages/graylog-4.2-repository_latest.rpm.key
Install Graylog by running the following command:
sudo zypper install graylog-server
Edit the Graylog server configuration file to specify the Elasticsearch URL. Open the /etc/graylog/server/server.conf
file using your preferred text editor:
sudo nano /etc/graylog/server/server.conf
Locate the following line:
elasticsearch_hosts = http://127.0.0.1:9200
Replace http://127.0.0.1:9200
with http://<IP_ADDRESS_OF_YOUR_SERVER>:9200
, where <IP_ADDRESS_OF_YOUR_SERVER>
is the IP address of your OpenSUSE server.
Start Graylog by running the following command:
sudo systemctl start graylog-server.service
Verify that Graylog is running by accessing the following URL in your web browser:
http://<IP_ADDRESS_OF_YOUR_SERVER>:9000/
If Graylog is working properly, you should see the Graylog login page.
Congratulations! You have successfully installed Graylog on OpenSUSE Latest.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
