Graylog is an open-source log management and analysis tool. It allows you to collect, index, and analyze log data from various sources in a centralized location. In this tutorial, we will guide you through the process of installing Graylog on NixOS Latest.
Before you start installing Graylog, make sure Java is installed on your server. You can check whether Java is installed by running the following command:
$ java -version
If Java is not installed on your system, you can install it by running the following command:
$ sudo nix-env -i openjdk
Graylog uses Elasticsearch as its backend database. You can install Elasticsearch by running the following command:
$ sudo nix-env -i elasticsearch
After the installation is complete, start the Elasticsearch service:
$ sudo systemctl start elasticsearch
Graylog uses MongoDB as its metadata storage engine. You can install MongoDB by running the following command:
$ sudo nix-env -i mongodb
After the installation is complete, start the MongoDB service:
$ sudo systemctl start mongodb
Now we are ready to install Graylog. You can install Graylog by running the following command:
$ sudo nix-env -i graylog
After Graylog is installed, you need to configure it. Open the Graylog configuration file:
$ sudo nano /etc/graylog/graylog.conf
Then, modify the following lines to match your server's IP address and Elasticsearch URL:
rest_listen_uri = http://YOUR_SERVER_IP:9000/api
web_listen_uri = http://YOUR_SERVER_IP:9000/
elasticsearch_hosts = http://localhost:9200
Save the file and exit.
Finally, start the Graylog service:
$ sudo systemctl start graylog-server
You can now access Graylog by opening a web browser and navigating to:
http://YOUR_SERVER_IP:9000
You should see the Graylog login page. Log in with the default credentials:
Username: admin
Password: password
That's it! You have successfully installed and configured Graylog on NixOS Latest. You can now start collecting and analyzing logs.
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!
