原因：1，新版本不允许用root启动，2，软件目录没相应的权限

解决：

groupadd es
useradd -g es es
passwd es

重新启动：

su es -c /opt/elasticsearch-2.4.3/bin/elasticsearch -Xmx2g -Xms2g -
Des.index.storage.type=memory –d > /dev/null 2>&1 &”

#因为我用的是虚拟机，内存比较小，所以启动看实际情况 -Xmx2g 是大内存 -Xms2g 是最小内存 -d 是后台运行
#我的运行命令是
su es -c /opt/elasticsearch/bin/elasticsearch –d > /dev/null 2>&1 &

安装插件：elasticsearch-head（是集群前段显示页面）

切换到bin目录下 执行

./plugin install  mobz/elasticsearch-head

页面展示：http://localhost/_plugin/head

测试：

curl http://localhost:9200 出现一个json 数据表明启动成功，如下

{

  "status": 200,

  "name": "Omen",

  "version": {

    "number": "1.1.1",

    "build_hash": "f1585f096d3f3985e73456debdc1a0745f512bbc",

    "build_timestamp": "2014-04-16T14:27:12Z",

    "build_snapshot": false,

    "lucene_version": "4.7"

  },

  "tagline": "You Know, for Search"

}

安装插件：elasticsearch-kopf

执行命令：

./plugin install lmenezes/elasticsearch-kopf

页面展示：http://localhost/_plugin/bigdesk/

4，安装kibana

tar zxvf kibana-4.6.3-linux-x86_64.tar.gz -C /opt

修改配置

因为和elasticsearch 在同一台服务器上，所以只需要修改elasticsearch的链接地址

elasticsearch_url: http://localhost:9200

启动

bin/kibana -p 5601 > /dev/null 2>&1 &

意思是以5601端口启动

然后以http://ip:5601访问就可以了
