deMacBook-Pro:elasticsearch-head-master yyq$ grunt server
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://localhost:9100
When I opened the url：http://localhost:9100 and clicked [connect] button, but I'm unable to connect to elasticsearch.
Could anyone help me?
This is the screenshot
In your elasticsearch.yml configuration, you probably have the following setting:
http.port: 9201
This is also visible in your logs:
[...] publish_address {127.0.0.1:9201}, bound_addresses {[fe80::1]:9201}, {[::1]:9201}, {127.0.0.1:9201}
^

your HTTP port
So in your elasticsearch-head interface, you need to connect to localhost:9201 not localhost:9200.
UPDATE
You also need to add http.cors.enabled: true in your elasticsearch.yml configuration and restart your ES server
