看來升級安裝后，服務(wù)會起不來，是node環(huán)境的問題，把之前的文件全部刪掉，全新安裝

端口沒監(jiān)聽在ipv4上。

看來下官方文檔， elasticsearch默認監(jiān)聽在localhost上，修改配置文件，把127.0.0.1改為本機ip

[root@dev elasticsearch]# vim elasticsearch.yml
network.host: 10.0.2.15
使用curl訪問下
[root@dev elasticsearch]# curl 10.0.2.15:9200

  "cluster_name" : "elasticsearch",
  "version" : {

安裝這兩個插件時會被墻掉，可以自己先wget下來，然后使用/usr/share/elasticsearch/bin/plugin install +rurl指定安裝包安裝。



如果需要使用http訪問elasticsearch數(shù)據(jù)庫，需要安裝head，安裝
/usr/share/elasticsearch/bin/plugin install mobz/elasticsearch-head
使用瀏覽器訪問  10.0.2.15:9200/_plugin/head/
可以看到數(shù)據(jù)。
