Elasticsearch 5.x安裝

node1	elasticsearch
node2	elasticsearch
node3	elasticsearch

 

前期準備

• JDK1.8
• 修改/etc/security/limits.conf

elasticsearch hard nofile 65536
elasticsearch soft nofile 65536

 1.下載並安裝

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.2.1.rpm
rpm -ivh elasticsearch-5.2.1.rpm

2.修改配置文件/etc/elasticsearch/elasticsearch.yml

cluster.name: test    #集羣名稱
node.name: es-node1    #（節點名稱）每一個節點不一樣
path.data:  /dfs/elasticsearch　　#能夠指定多個
path.logs:  /dfs/elasticsearch/logs
network.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
discovery.zen.ping.unicast.hosts: ["node1", "node2", "node3"]

若是調整內存，修改/etc/elasticsearch/jvm.options文件，兩個值須要一致。

　　-Xms2g
　　-Xmx2g

3.建立數據和日誌目錄

mkdir -p  /dfs/elasticsearch/logs
chown elasticsearch.elasticsearch -R /dfs/elasticsearch

4.修改/etc/init.d/elasticsearch

定義JAVA_HOME
export JAVA_HOME=/path/java（按照實際路徑修改）

啓動，若是有錯誤查看日誌排錯

/etc/init.d/elasticsearch start

5.安裝elasticsearch-head，5.x版本elasticsearch-head已經不能做爲插件安裝了

1.能夠使用chrome安裝elasticsearch-head插件
https://chrome.google.com/webstore/detail/elasticsearch-head/ffmkiejjmecolpfloofpjologoblkegm

2.使用python啓動
git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
python -m SimpleHTTPServer
會監聽在8000端口，而後訪問IP:8000
