##ES集群监控
获取es主机版本
curl -s -XGET 192.168.177.133:9200 | grep number
查询本机端口
find /home/ -name elasticsearch.yml | xargs cat | grep ^http.port
查询版本信息
curl -XGET 192.168.177.133:9200
查询集群信息
curl -XGET 'http://192.168.177.133:9200/_cat/nodes?pretty'
[root@es-master3 ~]# curl -XGET 'http://172.16.20.5:9201/_cat/nodes?pretty'
