elasticsearch-head中cluster health: not connected

修改elasticsearch安装目录中 config/elasticsearch.yml
http.cors.enabled: true
http.cors.allow-origin: “*”
修改elasticsearch-head下Gruntfile.js

connect: {
 server: {
 options: {
 hostname: ‘0.0.0.0’,
 port: 9100,
 base: ‘.’,
 keepalive: true
 }
 }
 }

注意：如果是绑定ip后，在页面的连接处写ip地址。默认是localhost，可能导致连接不上。
