<\/span><\/h3>\n\n\n\nElasticsearch components are not included in the default package repositories of Ubuntu. Nevertheless, you can install them via APT by adding Elastic’s package source list. To prevent package spoofing and ensure system security, all packages are signed with the signing key. Your package manager will consider the key-authenticated packages as trustworthy. To proceed with the installation, you need to import the public GPG key and add the Elastic package source list in this step.<\/p>\n\n\n\n
curl -fsSL https:\/\/artifacts.elastic.co\/GPG-KEY-elasticsearch |sudo gpg --dearmor -o \/usr\/share\/keyrings\/elastic.gpg\n\necho \"deb [signed-by=\/usr\/share\/keyrings\/elastic.gpg] https:\/\/artifacts.elastic.co\/packages\/7.x\/apt stable main\" | sudo tee -a \/etc\/apt\/sources.list.d\/elastic-7.x.list<\/code><\/pre>\n\n\n\n
Update your APT packages index with the new Elastic source:<\/p>\n\n\n\n
apt-get update<\/code><\/pre>\n\n\n\n<\/p>\n\n\n\n
Use the following command to install:<\/p>\n\n\n\n
sudo apt install elasticsearch<\/code><\/pre>\n\n\n\n
Elasticsearch has been installed and is now ready for configuration. You may utilize your preferred text editor to modify the main configuration file, which is the elasticsearch.yml file. In this case, we will use nano:<\/p>\n\n\n\n
nano \/etc\/elasticsearch\/elasticsearch.yml<\/code><\/pre>\n\n\n\nLocate the line in the configuration file that specifies “network.host”, remove the comment symbol, and substitute its value with “localhost” as demonstrated below:<\/p>\n\n\n
\n
Start the Elasticsearch service:<\/p>\n\n\n\n
sudo systemctl start elasticsearch<\/code><\/pre>\n\n\n\nsudo systemctl enable elasticsearch<\/code><\/pre>\n\n\n\ncurl -X GET \"localhost:9200\"<\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
<\/span>Setting up Kibana Dashboard<\/span><\/h3>\n\n\n\nKibana is an open-source data visualization and exploration tool designed to work with Elasticsearch. It provides users with a user-friendly web interface for analyzing and visualizing data stored in Elasticsearch indices. Kibana offers a wide range of features such as data filtering, aggregation, and visualization tools that enable users to interactively explore and understand their data. It is commonly used in conjunction with Elasticsearch for log analysis, business intelligence, and other analytical use cases.<\/p>\n\n\n\n
sudo apt install kibana\n
In order to enable external access to Kibana, which is currently set up to only listen on localhost, a reverse proxy needs to be established. For this purpose, Nginx will be used, assuming it has already been installed on the server.<\/p>\n\n\n\n
The first step involves creating an administrative Kibana user using the openssl command. This account will be used to access the Kibana web interface. For example, we will name this account “virtonoadmin”. However, to ensure greater security, it is recommended to choose a non-standard username that would be difficult to guess.<\/p>\n\n\n\n
Executing the following command will create the administrative Kibana user and password, and store them in the “htpasswd.users” file. Nginx will be configured to require this username and password and read this file in the next steps:<\/p>\n\n\n\n
echo \"virtonoadmin:openssl passwd -apr1\" | sudo tee -a \/etc\/nginx\/htpasswd.users<\/code><\/pre>\n\n\n\nnano \/etc\/nginx\/sites-available\/domain<\/mark><\/code><\/pre>\n\n\n\nAnd paste the following:<\/p>\n\n\n\n
server {\n listen 80;\n\n server_name your_domain; MAKE SURE TO REPLACE WITH YOUR DOMAIN\n\n auth_basic \"Restricted Access\";\n auth_basic_user_file \/etc\/nginx\/htpasswd.users;\n\n location \/ {\n proxy_pass http:\/\/localhost:5601;\n proxy_http_version 1.1;\n proxy_set_header Upgrade $http_upgrade;\n proxy_set_header Connection 'upgrade';\n proxy_set_header Host $host;\n proxy_cache_bypass $http_upgrade;\n }\n}<\/code><\/pre>\n\n\n\nsudo ln -s \/etc\/nginx\/sites-available\/domain \/etc\/nginx\/sites-enabled\/domain\nsudo nginx -t\nsudo systemctl reload nginx<\/code><\/pre>\n\n\n\n
To access the Kibana server’s status page, navigate to http:\/\/domain\/status<\/p>\n\n\n
\n
<\/span>Setting up Logstash<\/span><\/h3>\n\n\n\nUse the following command to install Logstash:<\/p>\n\n\n\n
apt install logstash<\/code><\/pre>\n\n\n\nGenerate a configuration file named “02-beats-input.conf” in which you will configure your Filebeat input:<\/p>\n\n\n\n
nano \/etc\/logstash\/conf.d\/02-beats-input.conf<\/code><\/pre>\n\n\n\nAdd the following lines to the conf file:<\/p>\n\n\n\n
input {\n beats {\n port => 5044\n }\n}<\/code><\/pre>\n\n\n\nThen, generate a configuration file named “30-elasticsearch-output.conf” and enter the following:<\/p>\n\n\n\n
nano \/etc\/logstash\/conf.d\/30-elasticsearch-output.conf\n\n\noutput {\n if [@metadata][pipeline] {\n\telasticsearch {\n \thosts => [\"localhost:9200\"]\n \tmanage_template => false\n \tindex => \"%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}\"\n \tpipeline => \"%{[@metadata][pipeline]}\"\n\t}\n } else {\n\telasticsearch {\n \thosts => [\"localhost:9200\"]\n \tmanage_template => false\n \tindex => \"%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}\"\n\t}\n }\n}\n<\/code><\/pre>\n\n\n\nCheck The Config Validation:<\/p>\n\n\n\n
sudo -u logstash \/usr\/share\/logstash\/bin\/logstash --path.settings \/etc\/logstash -t\n\nConfig Validation Result: OK. Exiting Logstash<\/code><\/pre>\n\n\n\nOnce your configuration test is deemed successful, commence and activate Logstash to apply the configuration modifications:<\/p>\n\n\n\n
