配置详解

# ---------------------------------- Cluster （集群配置）-----------------------------------  #  # cluster.name: my-application   （自定义集群名称，相同集群该名称相同  my-application）  #  # ------------------------------------ Node ------------------------------------  #   node.name: node-1     （当前节点名称，同一个集群中不能重复）    #  # Add custom attributes to the node:  #  # node.rack: r1  #  # ----------------------------------- Paths （数据，日志路径配合）------------------------------------  #  # Path to directory where to store the data (separate multiple locations by comma):  #   path.data: /home/yang/elasticsearch-2.2.0/data  (数据存储路径，支持多路径)  #  # Path to log files:  #   path.logs: /home/yang/elasticsearch-2.2.0/logs  （日志文件存储路径）  #  # ----------------------------------- Memory -----------------------------------  #  # Lock the memory on startup:  #  # bootstrap.mlockall: true   （是否锁住内存，指长期占用该内存，不产生内存交换，防止内存交换导致性能降低，配合内存设置使用）  #  # Make sure that the `ES_HEAP_SIZE` environment variable 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（网络配置） -----------------------------------  #  # Set the bind address to a specific IP (IPv4 or IPv6):  #  # network.host: 192.168.0.1      （IP地址，url访问的ip）  #  # Set a custom port for HTTP:  #  # http.port: 9200       （http访问端口）  #  # For more information, see the documentation at:  # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>  #  # --------------------------------- Discovery （节点发现配置）----------------------------------  #  # 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"]    （初始主节点列表，默认启动是按照这个初始化master节点）  #  # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):  #  # discovery.zen.minimum_master_nodes: 3（集群中可以知道其他n个有master自个节点，默认 节点数/2 + 1）  #  # For more information, see the documentation at:  # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html>  #  # ---------------------------------- Gateway-------------------------  #  # Block initial recovery after a full cluster restart until N nodes are started:  #  # gateway.recover_after_nodes: 3   (n个节点启动后开始数据恢复)  #  # For more information, see the documentation at:  # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html>  #  # ---------------------------------- Various -----------------------------------  #  # Disable starting multiple nodes on a single system:  #  # node.max_local_storage_nodes: 1  （禁用多节点从同一个位置启动）  #  # Require explicit names when deleting indices:  #  # action.destructive_requires_name: true  （设置是否可以通过正则或者_all删除或者关闭索引）
