elasticsearch5.5多機叢集配置

elasticsearch5.5多機叢集配置

ELasticsearch 5.5要求JDK版本最低為1.8;

配置叢集之前  先把要加群叢集的節點的裡的data目錄下的Node目錄 删除，否則叢集建立會失敗。

我這邊虛拟機配置了兩台centos IP分别是 192.168.1.110 和 192.168.1.111 ;

分别配置下elasticsearch.yml配置檔案

# ---------------------------------- Cluster -----------------------------------

#

# Use a descriptive name for your cluster:

#

cluster.name: my-application

#

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

#

# Use a descriptive name for the node:

#

node.name: master

#

# 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: 192.168.1.110

#

# 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: ["192.168.1.110"]

#

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

#

#discovery.zen.minimum_master_nodes: 3

#

# 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

http.cors.enabled: true

http.cors.allow-origin: "*"

#gateway.recover_after_nodes: 3

這裡兩台機器的cluster.name必須一緻 這樣才算一個叢集

node.name節點名稱每台取不同的名稱，用來表示不同的叢集節點

network.host配置成自己的區域網路IP

http.port端口就固定9200

discovery.zen.ping.unicast.hosts主動發現節點我們都配置成110節點IP

配置完後 重新開機es服務；

然後head插件我們檢視下：

說明叢集配置OK 。
