前提：
Elasticsearch-2.4.3的下載（圖文詳解）
Elasticsearch-2.4.3的單節點安裝（多種方式圖文詳解）
我這里，以192.168.80.10（HadoopMaster）、192.168.80.11(HadoopSlave1)、192.168.80.12(HadoopSlave2)三台機器，來安裝ES的3節點集群部署。
具體的，3集群搭建安裝基礎，請移步，先看
hadoop-2.6.0.tar.gz的集群搭建（3節點）

日志目錄：/home/hadoop/data/elasticsearch-2.4.3/datalog
進程目錄：/home/hadoop/data/elasticsearch-2.4.3/pid
三台均要去做。
ElasticSearch 集群環境檢查-時鍾同步
1.設置本地時間
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
2.集群時間日期同步NTP
yum install ntp
ntpdate pool.ntp.org
ElasticSearch 集群環境檢查-hosts文件檢查
配置ElasticSearch集群ip與hostname之間的對應關系
vi /etc/hosts
192.168.80.10 HadoopMaster
192.168.80.11 HadoopSlave1
192.168.80.12 HadoopSlave2
ElasticSearch 集群環境檢查-禁用防火牆
查看防火牆狀態
service iptables status
關閉防火牆
chkconfig iptables off //永久關閉防火牆
service iptables stop //臨時關閉防火牆
ElasticSearch jdk安裝
下載解壓
配置環境變量
這個很簡單，不多贅述
Elasticsearch-2.4.3的3節點安裝的前提步驟
1、HadoopMaster
[hadoop@HadoopMaster ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:0C:29:EE:5E:5B inet addr:192.168.80.10 Bcast:192.168.80.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:feee:5e5b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:258 errors:0 dropped:0 overruns:0 frame:0 TX packets:56 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:24027 (23.4 KiB) TX bytes:7192 (7.0 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:240 (240.0 b) TX bytes:240 (240.0 b) [hadoop@HadoopMaster ~]$ ssh HadoopSlave1 Last login: Wed Feb 22 00:34:08 2017 from 192.168.80.1 [hadoop@HadoopSlave1 ~]$ ssh HadoopSlave2 Last login: Wed Feb 22 00:34:09 2017 from 192.168.80.1 [hadoop@HadoopSlave2 ~]$ 證明，ssh免密碼登錄是可以的。
2、HadoopSlave1
[hadoop@HadoopSlave1 ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:0C:29:D8:AA:6A inet addr:192.168.80.11 Bcast:192.168.80.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fed8:aa6a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:249 errors:0 dropped:0 overruns:0 frame:0 TX packets:52 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:23321 (22.7 KiB) TX bytes:5876 (5.7 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:240 (240.0 b) TX bytes:240 (240.0 b) [hadoop@HadoopSlave1 ~]$ ssh HadoopMaster Last login: Wed Feb 22 00:34:06 2017 from 192.168.80.1 [hadoop@HadoopMaster ~]$ ssh HadoopSlave2 Last login: Wed Feb 22 00:34:45 2017 from hadoopslave1 [hadoop@HadoopSlave2 ~]$
3、HadoopSlave2
[hadoop@HadoopSlave2 ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:0C:29:FA:65:4A inet addr:192.168.80.12 Bcast:192.168.80.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fefa:654a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:199 errors:0 dropped:0 overruns:0 frame:0 TX packets:119 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:23401 (22.8 KiB) TX bytes:17008 (16.6 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:240 (240.0 b) TX bytes:240 (240.0 b) [hadoop@HadoopSlave2 ~]$ ssh HadoopMaster Last login: Wed Feb 22 00:38:54 2017 from hadoopslave1 [hadoop@HadoopMaster ~]$ ssh HadoopSlave1 Last login: Wed Feb 22 00:34:33 2017 from hadoopmaster [hadoop@HadoopSlave1 ~]$

3、刪除elasticsearch-2.4.3.tar.gz壓縮包
[hadoop@HadoopMaster app]$ ll total 26728 drwxrwxr-x. 6 hadoop hadoop 4096 Feb 22 01:37 elasticsearch-2.4.3 -rw-r--r--. 1 hadoop hadoop 27342693 Jan 10 11:38 elasticsearch-2.4.3.tar.gz drwxr-xr-x. 10 hadoop hadoop 4096 Oct 31 17:15 hadoop-2.6.0 drwxr-xr-x. 15 hadoop hadoop 4096 Nov 14 2014 hadoop-2.6.0-src drwxrwxr-x. 8 hadoop hadoop 4096 Nov 2 18:20 hbase-1.2.3 drwxr-xr-x. 8 hadoop hadoop 4096 Apr 11 2015 jdk1.7.0_79 drwxr-xr-x. 10 hadoop hadoop 4096 Nov 1 23:39 zookeeper-3.4.6 [hadoop@HadoopMaster app]$ rm elasticsearch-2.4.3.tar.gz [hadoop@HadoopMaster app]$ ll total 24 drwxrwxr-x. 6 hadoop hadoop 4096 Feb 22 01:37 elasticsearch-2.4.3 drwxr-xr-x. 10 hadoop hadoop 4096 Oct 31 17:15 hadoop-2.6.0 drwxr-xr-x. 15 hadoop hadoop 4096 Nov 14 2014 hadoop-2.6.0-src drwxrwxr-x. 8 hadoop hadoop 4096 Nov 2 18:20 hbase-1.2.3 drwxr-xr-x. 8 hadoop hadoop 4096 Apr 11 2015 jdk1.7.0_79 drwxr-xr-x. 10 hadoop hadoop 4096 Nov 1 23:39 zookeeper-3.4.6 [hadoop@HadoopMaster app]$

4、解讀認識ES的目錄結構
這里，以HadoopMaster為例
[hadoop@HadoopMaster elasticsearch-2.4.3]$ pwd
/home/hadoop/app/elasticsearch-2.4.3
[hadoop@HadoopMaster elasticsearch-2.4.3]$ ll
total 44
drwxrwxr-x. 2 hadoop hadoop 4096 Feb 22 01:37 bin
drwxrwxr-x. 2 hadoop hadoop 4096 Feb 22 01:37 config
drwxrwxr-x. 2 hadoop hadoop 4096 Feb 22 01:37 lib
-rw-rw-r--. 1 hadoop hadoop 11358 Aug 24 00:46 LICENSE.txt
drwxrwxr-x. 5 hadoop hadoop 4096 Dec 8 00:41 modules
-rw-rw-r--. 1 hadoop hadoop 150 Aug 24 00:46 NOTICE.txt
-rw-rw-r--. 1 hadoop hadoop 8700 Aug 24 00:46 README.textile
[hadoop@HadoopMaster elasticsearch-2.4.3]$
5、修改配置文件
進入$ES_HOME/config
[hadoop@HadoopMaster elasticsearch-2.4.3]$ cd config/ [hadoop@HadoopMaster config]$ pwd /home/hadoop/app/elasticsearch-2.4.3/config [hadoop@HadoopMaster config]$ ll total 8 -rw-rw-r--. 1 hadoop hadoop 3192 Aug 24 00:46 elasticsearch.yml -rw-rw-r--. 1 hadoop hadoop 2571 Aug 24 00:46 logging.yml [hadoop@HadoopMaster config]$ vim elasticsearch.yml
當然，這個配置文件，直接可以下載到本地，用Notepad++等軟件來打開。
# network.host: 192.168.0.1 # discovery.zen.ping.unicast.hosts: ["host1", "host2"]
# cluster.name: my-application
# node.name: node-1
# path.data: /path/to/data
# path.logs: /path/to/logs
改為 network.host: 0.0.0.0 （當然這里，可以寫為192.168.80.10）
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping_timeout: 120s
client.transport.ping_timeout: 60s discovery.zen.ping.unicast.hosts: ["192.168.80.10","192.168.80.11", "192.168.80.12"]
cluster.name: escluster
node.name: node-0
path.data: /home/hadoop/data/elasticsearch-2.4.3/data （當然若為了更專業，比如實現負載均衡，掛載不同盤上，則可以用多個目錄，用逗號隔開句好，這里為了學習只寫一個）
path.logs: /home/hadoop/data/elasticsearch-2.4.3/datalog
其實，這里自行去設置。這里牽扯到單播和多播
注意，這些一定要頂格。具體，更多詳細，見
elasticsearch-.yml（中文配置詳解）
對其他兩台也要進行同樣的配置文件修改工作。
# network.host: 192.168.0.1 # discovery.zen.ping.unicast.hosts: ["host1", "host2"] # cluster.name: my-application # node.name: node-1 # path.data: /path/to/data # path.logs: /path/to/logs 改為 network.host: 0.0.0.0 (當然，這里可以寫為192.168.80.11） discovery.zen.ping.multicast.enabled: false discovery.zen.ping_timeout: 120s client.transport.ping_timeout: 60s discovery.zen.ping.unicast.hosts: ["192.168.80.10","192.168.80.11", "192.168.80.12"] cluster.name: escluster node.name: node-1 path.data: /home/hadoop/data/elasticsearch-2.4.3/data （當然若為了更專業，比如實現負載均衡，掛載不同盤上，則可以用多個目錄，用逗號隔開句好，這里為了學習只寫一個） path.logs: /home/hadoop/data/elasticsearch-2.4.3/datalog 其實，這里自行去設置。這里牽扯到單播和多播
# network.host: 192.168.0.1 # discovery.zen.ping.unicast.hosts: ["host1", "host2"] # cluster.name: my-application # node.name: node-1 # path.data: /path/to/data # path.logs: /path/to/logs 改為 network.host: 0.0.0.0 （當然這里，可以寫為192.168.80.12） discovery.zen.ping.multicast.enabled: false discovery.zen.ping_timeout: 120s client.transport.ping_timeout: 60s discovery.zen.ping.unicast.hosts: ["192.168.80.10","192.168.80.11", "192.168.80.12"] cluster.name: escluster node.name: node-2 path.data: /home/hadoop/data/elasticsearch-2.4.3/data （當然若為了更專業，比如實現負載均衡，掛載不同盤上，則可以用多個目錄，用逗號隔開句好，這里為了學習只寫一個） path.logs: /home/hadoop/data/elasticsearch-2.4.3/datalog 其實，這里自行去設置。這里牽扯到單播和多播
或者用scp命令，進行分發，這個很簡單！
ElasticSearch 插件安裝（含 head、kopf、marvel、shield和watcher插件安裝）
安裝marvel插件（所有節點都需要安裝）（在線安裝）
bin/plugin install license
bin/plugin install marvel-agent
安裝head插件（選擇一個節點安裝即可）（在線安裝）（其實安裝一個節點就可以看到整個集群的了）（我這里就3個節點都安裝了）
bin/plugin install mobz/elasticsearch-head
6、下載並安裝插件（含 head、kopf、marvel、shield和watcher插件安裝）

Elasticsearch之kopf插件安裝之后的瀏覽詳解
我這里，以離線方式來安裝es插件之Head Plugin 、Kopf Plugin。
以在線方式來安裝es插件之和marvel插件。
安裝 head和kopf插件：

安裝shield插件：
（所有節點都需要安裝）（HadoopMaster、HadoopSlave1和Hadoopslave2）
默認情況下elasticsearch可以不受限制訪問，如果在外網的情況下就不安全了，所以，elastic官方提供了shield插件，可以實現權限控制，但是不好的地方就是這個插件是收費的，可以免費試用一個月。那我就帶你來試試吧！
我告訴你一個小技巧：等到30天之后，卸載 shield，再重新安裝就是。該如何卸載，后面我也有寫。
Shield 插件必須安裝在集群中的每一個節點，並且每一個節點在安裝完成之后必須要重啟才能生效。
我這里，是3節點集群，所以HadoopMaster、HadoopSlave1和HadoopSlave2都安裝shield插件。
注意：你必須保證Shield的版本和你運行的Elasticsearch的版本保持一致。

同理，HadoopSlave1和HadoopSlave2也如上述步驟。
然后，默認情況下es並沒有禁用自動創建索引庫功能。
假設，若你在以后時，如果你在es中禁用了自動創建索引庫的功能。那么你需要在elasticsearch.yml中配置action.auto_create_index 以便允許Shield去創建.security 索引庫。action.auto_create_index: .security
這里，我不贅述。
然后，啟動/重啟es
安裝shield插件之后，如何來使用呢？(HadoopMaster、HadoopSlave1、HadoopSlave2)
創建用戶：
用戶級別分為以下三種：
（1）admin:可以對就所有集群或者索引庫執行操作
（2）power_user:可以監控集群並且對所有索引庫執行操作
（3）user:可以對所有索引庫執行read操作
創建用戶命令：【執行之后會提示用戶設置密碼】
bin/shield/esusers useradd es_admin -r admin 解釋： useradd：表示添加用戶 es_admin：表示要新建的用戶名稱 -r：指定權限信息 admin：給新建的用戶賦予admin權限
注意：當提示輸入密碼的時候，給新用戶設置一個新密碼，密碼必須至少包含6個字符。比如我這里設置為123456
這也是，為什么后續，編程java api時，需要用到的地方。見如下：
使用java api操作es需要注意的地方（Elasticsearch開啟shield插件之后）
訪問es：-u es_admin 表示使用用戶es_admin進行訪問
[hadoop@HadoopMaster elasticsearch-2.4.3]$ pwd /home/hadoop/app/elasticsearch-2.4.3 [hadoop@HadoopMaster elasticsearch-2.4.3]$ curl -u es_admin -XGET 'http://192.168.80.10:9200/' Enter host password for user 'es_admin': { "name" : "node-0", "cluster_name" : "escluster", "cluster_uuid" : "gBwdRD7iRRyC6TRji7ohFw", "version" : { "number" : "2.4.3", "build_hash" : "d38a34e7b75af4e17ead16f156feffa432b22be3", "build_timestamp" : "2016-12-07T16:28:56Z", "build_snapshot" : false, "lucene_version" : "5.5.2" }, "tagline" : "You Know, for Search" } [hadoop@HadoopMaster elasticsearch-2.4.3]$
curl -u es_admin -XGET 'http://localhost:9200/'
或
curl -u es_admin -XGET 'http://192.168.80.10:9200/'
[hadoop@HadoopSlave1 elasticsearch-2.4.3]$ pwd /home/hadoop/app/elasticsearch-2.4.3 [hadoop@HadoopSlave1 elasticsearch-2.4.3]$ bin/shield/esusers useradd es_admin -r admin Enter new password: Retype new password: [hadoop@HadoopSlave1 elasticsearch-2.4.3]$ curl -u es_admin -XGET 'http://192.168.80.11:9200/' Enter host password for user 'es_admin': { "name" : "node-1", "cluster_name" : "escluster", "cluster_uuid" : "gBwdRD7iRRyC6TRji7ohFw", "version" : { "number" : "2.4.3", "build_hash" : "d38a34e7b75af4e17ead16f156feffa432b22be3", "build_timestamp" : "2016-12-07T16:28:56Z", "build_snapshot" : false, "lucene_version" : "5.5.2" }, "tagline" : "You Know, for Search" } [hadoop@HadoopSlave1 elasticsearch-2.4.3]$
[hadoop@HadoopSlave2 elasticsearch-2.4.3]$ pwd /home/hadoop/app/elasticsearch-2.4.3 [hadoop@HadoopSlave2 elasticsearch-2.4.3]$ bin/shield/esusers useradd es_admin -r admin Enter new password: Retype new password: [hadoop@HadoopSlave2 elasticsearch-2.4.3]$ curl -u es_admin -XGET 'http://192.168.80.12:9200/' Enter host password for user 'es_admin': { "name" : "node-2", "cluster_name" : "escluster", "cluster_uuid" : "gBwdRD7iRRyC6TRji7ohFw", "version" : { "number" : "2.4.3", "build_hash" : "d38a34e7b75af4e17ead16f156feffa432b22be3", "build_timestamp" : "2016-12-07T16:28:56Z", "build_snapshot" : false, "lucene_version" : "5.5.2" }, "tagline" : "You Know, for Search" } [hadoop@HadoopSlave2 elasticsearch-2.4.3]$
訪問的會提示輸入剛才設置的密碼。（我剛才輸入的密碼是123456，用戶名是es_admin）。
這樣以后再訪問es的時候就需要輸入用戶名和密碼了。
kibana中也能使用shield
具體見，https://www.elastic.co/guide/en/shield/current/kibana.html
以后寫上，
如果您的安全要求更復雜，你可以這樣做：
1、定義和使用細粒度訪問控制的自定義角色
2、使用LDAP或Active Directory集成，或使用證書的認證。
3、使用IP過濾來自特定IP地址或地址范圍的請求
具體，見https://www.elastic.co/guide/en/shield/current/ip-filtering.html
目前是試用期30天（商業），如何卸載shield？
如果不想使用shield，需要移除掉。
第一步：停止es
第二步：從es中移除shield插件
[hadoop@HadoopSlave2 elasticsearch-2.4.3]$ bin/plugin remove shield
第三步：啟動es.
[hadoop@HadoopSlave2 elasticsearch-2.4.3]$ jps 2394 Jps [hadoop@HadoopSlave2 elasticsearch-2.4.3]$ bin/elasticsearch -d [hadoop@HadoopSlave2 elasticsearch-2.4.3]$ jps 2428 Jps 2415 Elasticsearch
這樣做的目的是，為了再次重新使用30天，目前，只能這樣個傻瓜辦法了。
安裝watcher插件：
（所有節點都需要安裝）（HadoopMaster、HadoopSlave1和Hadoopslave2）
watcher插件可以提供elasticsearch集群的監控提醒功能。
你需要在你的集群中所有節點安裝license和watcher插件。

Continue with installation? [y/N]y Installed watcher into /home/hadoop/app/elasticsearch-2.4.3/plugins/watcher [hadoop@HadoopSlave2 elasticsearch-2.4.3]$
默認這一步不需要操作，因為默認情況下es並沒有禁用自動創建索引庫功能。
如果你在es中禁用了自動創建索引庫的功能。那么你需要在elasticsearch.yml中配置action.auto_create_index 以便允許watcher去創建.watches, .triggered_watches, and .watcher-history* 索引庫。
如果你已經安裝了shield，你必須允許shield創建.security索引庫
這里，我不贅述。
然后，啟動/重啟es
驗證watcher插件后的效果

暫時，放這里。
監控功能：
1：監控錯誤日志
具體見，https://www.elastic.co/guide/en/watcher/current/watch-log-data.html
2：監控集群監控狀態
具體見，https://www.elastic.co/guide/en/watcher/current/watch-cluster-status.html
下面以監控集群狀態為例演示：
1：創建一個每10秒運行一次的調度器
curl -XPUT 'http://192.168.80.10:9200/_watcher/watch/cluster_health_watch' -d '{
"trigger" : {
"schedule" : { "interval" : "10s" }
}
}'
2：給這個調度器增加一個input，把集群的健康狀態添加到watcher中
curl -XPUT 'http://192.168.80.10:9200/_watcher/watch/cluster_health_watch' -d '{
"trigger" : {
"schedule" : { "interval" : "10s" }
},
"input" : {
"http" : {
"request" : {
"host" : "192.168.80.100",
"port" : 9200,
"path" : "/_cluster/health"
}
}
}
}'
3：給這個wacher添加一個條件,判斷集群的狀態是否為red
curl -XPUT 'http://192.168.80.100:9200/_watcher/watch/cluster_health_watch' -d '{
"trigger" : {
"schedule" : { "interval" : "10s" }
},
"input" : {
"http" : {
"request" : {
"host" : "192.168.80.100",
"port" : 9200,
"path" : "/_cluster/health"
}
}
},
"condition" : {
"compare" : {
"ctx.payload.status" : { "eq" : "red" }
}
}
}'
4：給watcher設置觸發任務，當滿足條件的時候，執行。
一般都是發送郵件。
所以需要先配置郵箱信息。修改es的配置文件。
vi conf/elasticsearch.yml
watcher.actions.email.service.account: work: profile: qqmail smtp: auth: true starttls.enable: true host: smtp.qq.com port: 587 user: 12345677@qq.com password: 12345678
添加觸發任務【手動把某一個索引庫的分片刪除一部分可以模擬分片丟失，集群狀態會變為red，此任務就會被觸發，發送郵件。】
curl -XPUT 'http://192.168.80.100:9200/_watcher/watch/cluster_health_watch' -d '{
"trigger" : {
"schedule" : { "interval" : "10s" }
},
"input" : {
"http" : {
"request" : {
"host" : "192.168.80.100",
"port" : 9200,
"path" : "/_cluster/health"
}
}
},
"condition" : {
"compare" : {
"ctx.payload.status" : { "eq" : "yellow" }
}
},
"actions" : {
"send_email" : {
"email" : {
"to" : "87654321@qq.com",
"subject" : "Cluster Status Warning",
"body" : "Cluster status is RED"
}
}
}
}'
驗證集群狀態，如果集群狀態為red，則剛才配置的watcher任務就會執行，發送郵件提醒。
curl -XGET 'http://192.168.80.10:9200/_cluster/health?pretty'
5：實驗結束，可以移除掉這個watcher
curl -XDELETE 'http://192.168.80.10:9200/_watcher/watch/cluster_health_watch'
目前是試用期30天（商業），如何卸載watcher？
第一步：停止Elasticsearch.
第二步：從Elasticsearch中移除watcher:
bin/plugin remove watcher
第三步：啟動Elasticsearch.
7、啟動，驗證
[hadoop@HadoopMaster elasticsearch-2.4.3]$ jps
2020 Jps
[hadoop@HadoopMaster elasticsearch-2.4.3]$ bin/elasticsearch -d
[hadoop@HadoopMaster elasticsearch-2.4.3]$ jps
2054 Jps
2041 Elasticsearch
[hadoop@HadoopMaster elasticsearch-2.4.3]$
其實啊，或者通過es的這種后台來啟動也是可以的。
bin/elasticsearch -d -p /home/hadoop/data/elasticsearch-2.4.3/pid
輸入，http://192.168.80.10:9200/
以上是默認的。
以上是自己修改了es的配置文件得到的。

三個節點的整個。
啟動head插件界面
注意：每次啟動會隨機生成一個節點名稱 。
默認情況下，三台機器，內部默認選舉，選出哪台是主節點，但是對於我們而言，也可以自己限制出哪台是主節點。
在這里，要說明一個問題：
出現了 no_route_to_host_exception: No route to host ，最后查博客得知，是防火牆沒關閉，建議作永久關閉，即 chkconfig iptables off 。
我們通過http請求連接es是走9200端口
