Installation and operation

Runs as a standalone webapp



When using npm to install the package, remember to add sudo (executed with root administrator privileges), otherwise an error may be reported. The results of the run are as follows:



We visit: http://ip:9100/ to see the web management interface, enter the API interface address of elasticsearch, and click Connect as follows:



Open the console console and get the following error:

Failed to load http://itsvse:9200/: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://itsvse:9100' is therefore not allowed access.
The error is due to the fact that Elasticsearch's API does not allow cross-domain requests. Kill the elasticsearch process first:

[es@VM_0_9_centos elasticsearch-6.5.2]$ jps
22257 Elasticsearch
23143 Jps
[es@VM_0_9_centos elasticsearch-6.5.2]$ kill -9 22257
[es@VM_0_9_centos elasticsearch-6.5.2]$ jps
23191 Jps
[es@VM_0_9_centos elasticsearch-6.5.2]$

Edit the elasticsearch configuration file

At the bottom, add a configuration that allows cross-domain:



Save the configuration file, and start elasticsearch, we try it with "elasticsearch-head" connection, and it succeeds, as follows:
