這里用的系統版本是CentOS6.6。

192.168.3.56 ES01 192.168.3.49 ES02 192.168.3.57 ES03

1、為三個節點安裝java環境

# yum install -y java java-1.8.0-openjdk-devel # vim /etc/profile.d/java.sh export JAVA_HOME=/usr # source /etc/profile.d/java.sh

2、同步時間

# ntpdate pool.ntp.org

3、上官網下載rpm包，或者按照guide設置官方repo，分別為三個節點安裝ES

# yum install -y elasticsearch-5.4.1.rpm

https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html

4、修改配置文件

節點1，ES01：

# vim /etc/elasticsearch/elasticsearch.yml cluster.name: oupenges node.name: es01 bootstrap.system_call_filter: false http.cors.enabled: true http.cors.allow-origin: "*" bootstrap.memory_lock: true network.host: 192.168.3.56 discovery.zen.ping.unicast.hosts: ["192.168.3.56", "192.168.3.49", "192.168.3.57"]

節點2，ES02：

# vim /etc/elasticsearch/elasticsearch.yml cluster.name: oupenges node.name: es02 bootstrap.system_call_filter: false http.cors.enabled: true http.cors.allow-origin: "*" bootstrap.memory_lock: true network.host: 192.168.3.49 discovery.zen.ping.unicast.hosts: ["192.168.3.56", "192.168.3.49", "192.168.3.57"]

節點3，ES03：

# vim /etc/elasticsearch/elasticsearch.yml cluster.name: oupenges node.name: es03 bootstrap.system_call_filter: false http.cors.enabled: true http.cors.allow-origin: "*" bootstrap.memory_lock: true network.host: 192.168.3.57 discovery.zen.ping.unicast.hosts: ["192.168.3.56", "192.168.3.49", "192.168.3.57"]

兩個http參數的含義可以參考這里：
https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-http.html

5、修改limits.conf，系統默認的1024太小，這里需要至少2048才能啟動服務

# vim /etc/security/limits.conf * hard nofile 65536 * soft nofile 65536 * hard memlock unlimited * soft memlock unlimited elasticsearch hard nproc 514834 elasticsearch soft nproc 514834

https://www.elastic.co/guide/en/elasticsearch/reference/current/setting-system-settings.html#limits.conf
https://www.elastic.co/guide/en/elasticsearch/reference/current/_memory_lock_check.html

6、啟動服務

# service elasticsearch start # chkconfig elasticsearch on

7、通過cluster API查看集群狀態：

# curl -XGET 'http://192.168.3.56:9200/_cluster/health?pretty=true' {"cluster_name" : "oupenges","status" : "green","timed_out" : false,"number_of_nodes" : 3,"number_of_data_nodes" : 3,"active_primary_shards" : 71,"active_shards" : 142,"relocating_shards" : 0,"initializing_shards" : 0,"unassigned_shards" : 0,"delayed_unassigned_shards" : 0,"number_of_pending_tasks" : 0,"number_of_in_flight_fetch" : 0,"task_max_waiting_in_queue_millis" : 0,"active_shards_percent_as_number" : 100.0 }

8、安裝head插件（需要事先安裝nodejs和phantomjs，這里只說一下phantomjs）

安裝phantomjs：

# wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2 # tar xvf phantomjs-2.1.1-linux-x86_64.tar.bz2 # cd phantomjs-2.1.1-linux-x86_64/ # ln -sv /root/phantomjs-2.1.1-linux-x86_64/bin/phantomjs /usr/bin/

運行head：

# git clone https://github.com/mobz/elasticsearch-head.git # cd elasticsearch-head/# npm install # nohup npm run start &

默認監聽9100端口，用瀏覽器訪問：http://192.168.3.56:9100/
