ElasticSearch 6.x集群安装

ES6.x安装过程：

进入服务器，修改服务器配置：

sudo vim /etc/sysctl.conf #增加以下内容： vm.max_map_count=262144 #保存退出vim后使sysctl.conf生效： sudo sysctl -p

sudo vim /etc/security/limits.conf

work soft nofile 65536 work hard nofile 65536 work soft nproc 65536 work hard nproc 65536  work soft memlock unlimited work hard memlock unlimited

退出登录服务器，然后重新登录，否则在ES启动时会发现配置未生效。

下载Elasticsearch安装包，解压，进入目录

下载插件：

bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.3.2/elasticsearch-analysis-ik-6.3.2.zip

 

进入安装包的config目录 

 

vim elasticsearch.yml

# ======================== Elasticsearch Configuration Start=========================

#

# 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: elasticsearch

#

# ------------------------------------ Node ------------------------------------

#

# Use a descriptive name for the node:

#

node.name: ics-prod01

#

# 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: /data/es-6.3.2/data

#

# Path to log files:

#

path.logs: /data/es-6.3.2/logs

#

# ----------------------------------- Memory -----------------------------------

#

# Lock the memory on startup:

#

bootstrap.memory_lock: true  锁定服务器内存，防止swap

#

# 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: 172.31.12.144

#

# Set a custom port for HTTP:

#

http.port: 9200

#

# 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: ["172.31.12.208", "172.31.12.226"]

#

# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):

#

discovery.zen.minimum_master_nodes: 2

#

# 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: 2

#

# For more information, consult the gateway module documentation.

#

# ---------------------------------- Various -----------------------------------

#

# Require explicit names when deleting indices:

#

action.destructive_requires_name: true

reindex.remote.whitelist: ["172.31.12.127:9200","172.31.12.42:9200"]  此处配置是为了从旧集群迁移数据至本集群，reindex白名单值得是旧es集群的ip

# ======================== Elasticsearch Configuration  End=========================

 

vim jvm.options 更改jvm启动项

-Xms8g

-Xmx8g

这两个值由原来的2g变更为8g，值越大越好，但不能超过32g。
