Elasticsearch-head is a Web front-end for an Elasticsearch cluster. For Elasticsearch 5.x, site plugins are not supported, so it needs to run as a standalone server. Follow these steps:
Install Node.js and npm from the official website.
Download the elasticsearch-head ZIP file and decompress it:
$ wget https://github.com/mobz/elasticsearch-head/archive/master.zip $ unzip master.zip
Install the modules and run the service:
$ cd elasticsearch-head-master $ npm install $ ./node_modules/grunt/bin/grunt server &
Update the /opt/bitnami/elasticsearch/config/elasticsearch.yml file and enable CORS by setting http.cors.enabled to true:
In the same file, set the http.cors.allow-origin variable to the domains that are allowed to send cross-origin requests. If you prepend and append a “/” to the value, this will be treated as a regular expression. For example:
NOTE: You can set the value of http.cors.allow-origin to “*” to allow CORS requests from anywhere if you wish. However, this is not recommended as it is a security risk.
Add Apache configuration for elasticsearch-head to /opt/bitnami/elasticsearch/apache-conf/elasticsearch.conf:
ProxyPass /elasticsearch-head http://127.0.0.1:9100 ProxyPassReverse /elasticsearch-head http://127.0.0.1:9100
Restart the services:
$ sudo /opt/bitnami/ctlscript.sh restart apache
Browse to http://SERVER-IP/elasticsearch-head/?base_uri=http://SERVER-IP/elasticsearch and insert your Elasticsearch credentials. You should see something like the screenshot below:
