前提：
Elasticsearch-2.4.3的下载（图文详解）
1、新建es安装目录
[root@djt002 local]# mkdir elasticsearch

2、上传elasticsearch-2.4.3.tar.gz
[hadoop@djt002 elasticsearch]$ pwd
/usr/local/elasticsearch
[hadoop@djt002 elasticsearch]$ rz
3、解压
[hadoop@djt002 elasticsearch]$ ls
elasticsearch-2.4.3.tar.gz
[hadoop@djt002 elasticsearch]$ tar -zxvf elasticsearch-2.4.3.tar.gz
4、删除压缩包
[hadoop@djt002 elasticsearch]$ rm elasticsearch-2.4.3.tar.gz
5、熟悉下es目录结构
[hadoop@djt002 elasticsearch]$ pwd
/usr/local/elasticsearch
[hadoop@djt002 elasticsearch]$ ls
elasticsearch-2.4.3
[hadoop@djt002 elasticsearch]$ cd elasticsearch-2.4.3/

6、启动es
方式一（不建议，只能在本机访问）
注意：es启动之后啊，会绑定两个端口，9200和9300.
bin/elasticsearch 注意： 这样启动只能通过 127.0.0.1:9200 访问

[hadoop@djt002 elasticsearch-2.4.3]$
方式二（建议，既能在本机访问，也能在内网访问）
建议修改 es 的配置文件 （一般建议这种）
vi config/elasticsearch.yml
network.host: 192.168.80.200
这个属性要顶格写， 并且冒号和值之间要有一个空格
bin/elasticsearch
这样再启动， 就可以通过 192.168.80.200:9200 访问
或者可以这样设置
vi config/elasticsearch.yml
network.host: 0.0.0.0
这样再启动， 可以通过 127.0.0.1:9200 和 192.168.80.200:9200 访问

7、es的验证
修改方式的总结:
、修改config/elasticsearch.yml
、或者在启动es的时候指定参数 （也可以是0.0.0.0，即任何主机）
如bin/elasticsearch -Dnetwork.host=192.168.80.200 （但这样，每次很麻烦！）
、es 安装注意事项， 以及容易出现问题的地方
(1)： 关闭服务器防火墙
service iptables stop
chkconfig iptables off
(2)： network.host 属性需要设置【 如果不设置的话只能通过 127.0.0.1 来进行访问】
network.host: 192.168.80.200 【注 意 ： 冒 号 后 面 必 须 要 有 空 格 ， 这 样 只 能 通 过192.168.80.200 访问 es】
或者 network.host: 0.0.0.0 【 这样可以通过此服务器的所有 ip 访问 es， 包括 127.0.0.1】
(3)： es 的访问端口问题
默认 es 会监听 9200 端口， 可以通过 http 请求进行访问。
但是要注意： 如果在一个节点上连续启动多个 es 实例的话， es 监听的端口号会递增，
9201,9202.....
(4)： 如果发现 es 启动之后在浏览器无法正常访问
建议查看 es 的启动日志， 确认 es 启动的时候是否报错， 以及绑定的 ip 和端口是多少。
前台方式启动 es 的话， 可以直接在控制台查看 es 的启动日志、
后台方式启动 es 的话， 可以到 ES_HOME/logs/elasticsearch.log 文件中查看日志
