ElasticSearch第四篇:启动和遇到的坑

---

关闭原来的服务：ps -ef | grep 'pwd'

启动方式：
启动es：elasticsearch
访问：http://127.0.0.1:9200/

启动kibana：kibana
http://127.0.0.1:5601/app/kibana#/dev_tools/console?_g=()

启动elasticsearch-head：npm run start
进入/Users/cici/workspace/es/elasticsearch-head 文件下
访问：http://127.0.0.1:9100/

---

问题：
访问一：http://127.0.0.1:9200/
出现的是最新的版本：

{
name: "wJ_4yyW",
cluster_name: "elasticsearch_cici",
cluster_uuid: "7-avDstMQYKSlVve05Wcyw",
version: {
number: "6.8.2",
build_flavor: "oss",
build_type: "tar",
build_hash: "b506955",
build_date: "2019-07-24T15:24:41.545295Z",
build_snapshot: false,
lucene_version: "7.7.0",
minimum_wire_compatibility_version: "5.6.0",
minimum_index_compatibility_version: "5.0.0"
},
tagline: "You Know, for Search"
}

插件显示结果：

访问二：http://localhost:9200/
出现的是

{
name: "Jane Foster",
cluster_name: "elasticsearch",
cluster_uuid: "G_EwB3J9RraU_w0ebozjUw",
version: {
number: "2.4.5",
build_hash: "c849dd13904f53e63e88efc33b2ceeda0b6a1276",
build_timestamp: "2017-04-24T16:18:17Z",
build_snapshot: false,
lucene_version: "5.5.4"
},
tagline: "You Know, for Search"
}

并且用http://localhost:9100/访问，集群健康值: 未连接

说明：此时的127.0.0.1 和 localhost 不是一个es服务;
查看本地docker镜像中发现，之前已经启动了2.4.5的服务
