elasticsearch安装及集群环境搭建

准备工作

1.centos7 :创建用户es、关闭防火墙、修改ulimit为65536
2.安装jdk8
3.下载elasticsearch-5.1.2.tar.gz 解压到/home/es/下
201702049527_536

一、单台机器安装(192.168.254.209)

1.配置文件目录

201702044330_801

2.修改jvm.options、

201702047688_147

3.修改elasticsearch.yml(注意未注释的配置)
# ======================== Elasticsearch Configuration =========================        
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 192.168.254.210
#
# Set a custom port for HTTP:
#
http.port: 9200
node.master: true
node.data: true
http.enabled: true
http.cors.enabled: true
http.cors.allow-origin: "*"
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.zen.ping.unicast.hosts: ["192.168.254.210"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
discovery.zen.minimum_master_nodes: 1
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
4.启动

cd /home/es/elasticsearch-5.1.2/bin 执行 ./elasticsearch
201702043376_739

5.浏览器查看

二、集群安装

第二台机器192.168.254.210,和209机器同样的配置
然后略微修改elasticsearch.yml :

node.master: false
node.name:node2
discovery.zen.ping.unicast.hosts:["192.168.254.209"]

然后启动
201702046097_792
红框中可看出已连上master节点(node1),而此时master控制台提示:
201702048827_444
也提示node2加入了集群

浏览器查看
http://192.168.254.209:9200/
201702049079_844

http://192.168.254.209:9200/_cluster/health?pretty
201702043586_125
可以看到集群中有两个节点

更多机器的集群,参考以上配置

三、附件下载

jvm.options
elasticsearch.yml
elasticsearch-5.1.2.tar.gz
kibana-5.1.2-windows-x86.zip
