Beginning Elastic Stack - Installing Kibana 7.9 on Ubuntu 20.04
By Securitynik on 2020-10-05 12:56:59
In the previous post, we installed and configured Elasticsearch on Ubuntu 20.04. In this post, we install and configure Kibana on Ubuntu 20.04. Since we already installed some of the prerequisites in the previous post, let's focus now on installing and configuring Kibana. 
root@securitynik-monitoring:/etc/elasticsearch# apt-get update && apt-get install kibana
...

Unpacking kibana (7.9.2) ...
Setting up kibana (7.9.2) ...
Processing triggers for systemd (245.4-4ubuntu3.2) ...
As before, I changed into Kibana directory and made a copy of the original config file. 
root@securitynik-monitoring:/etc/elasticsearch# cd /etc/kibana/
root@securitynik-monitoring:/etc/kibana# cp kibana.yml kibana.yml.ORIGINAL
Here are the options I un-commented and or modified. 
root@securitynik-monitoring:~# cat /etc/kibana/kibana.yml | grep --perl-regexp "^server.port|^server.host|^server.name|^elasticsearch.host|^elasticsearch.logQueries|run"
server.port: 5601
server.host: "10.0.0.1"
server.name: "kibana.securitynik.local"
elasticsearch.hosts: ["http://10.0.0.1:9200"]
elasticsearch.logQueries: true

pid.file: /var/run/kibana/kibana.pid
To prevent Kibana from throwing the error "message":"{ [Error: EACCES: permission denied, open '/var/run/kibana.pid']", I created a directory named "kibana" under "/var/run/" and made the "kibana" user the owner. 
root@securitynik-monitoring:~# mkdir /var/run/kibana
root@securitynik-monitoring:~# chown kibana.kibana /var/run/kibana/
root@securitynik-monitoring:~# ls -al /var/run/
...

Configuring Kibana service. 
root@securitynik-monitoring:/etc/kibana# systemctl daemon-reload
root@securitynik-monitoring:/etc/kibana# systemctl enable --now kibana.service
Synchronizing state of kibana.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable kibana
Created symlink /etc/systemd/system/multi-user.target.wants/kibana.service → /etc/systemd/system/kibana.service.
Verify the service is running. 
root@securitynik-monitoring:/etc/kibana# systemctl status kibana.service

Looks good! Verify the service is listening on port 5601. 
root@securitynik-monitoring:/etc/kibana# ss --numeric --listen --process --tcp --udp

Looks like the Kibana service is available on port 5601. Time for the final validation. This will be done by connecting to the web UI.

At this point, you have the option of using the sample data provided by Elastic or explore on your own. We will explore on our own in future posts by taking advantage of the various Beats. Those are Filebeat, Packetbeat, Winlogbeat, Auditbeat and Metricbeat.
With this done, let's now move to the next post, where we provide some basic security to the communication between the Elastic stack components. Posts in this series:
