一般情况下单台服务器只会部署一个ElasticSearch node,但是在学习过程中,很多情况下会需要实现ElasticSearch的分布式效果,所以需要启动多个节点,但是学习开发环境(不想开多个虚拟机实现多个服务器的效果),所以就想着在一台服务器上部署多个结点(下文以2个结点作为例子),两个节点分别称为实例一、二。
1、首先将elasticsearch-5.4.0文件夹再复制一份
cp -R elasticsearch-5.4.0 elasticsearch-5.4.0-node2
2、修改节点1的配置文件
# ======================== 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: elk-cluster #cluster.name 要保持一致 # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node1 # # Add custom attributes to the node: # #node.attr.rack: r1 # node.master: true #该节点有机会成为master节点 transport.tcp.port: 9300 # 默认里没有自己添加 # ----------------------------------- 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: 192.168.25.129 # # 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: ["host1", "host2"] # # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): # discovery.zen.minimum_master_nodes: 1 #设置这个参数来保证集群中的节点可以知道其它N个有成为master资格的节点 # # 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
2、修改节点2的配置文件

4.启动两个节点,用Kibana查看
至此,多节点搭建成功。
踩过的坑
1.node2无法启动 是因为复制的elasticsearch文件夹下包含了data文件中node1的节点数据,需要把node1 data文件下的文件清空。
