elasticsearch-.yml（中文配置详解）

# ======================== 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 see the documentation for further information on configuration options: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html> # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # 集群名称，默认是elasticsearch # cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # 节点名称，默认从elasticsearch-2.4.3/lib/elasticsearch-2.4.3.jar!config/names.txt中随机选择一个名称 # node.name: node-1 # # Add custom attributes to the node: #  # node.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # 可以指定es的数据存储目录，默认存储在es_home/data目录下 # path.data: /path/to/data # # Path to log files: # 可以指定es的日志存储目录，默认存储在es_home/logs目录下 # path.logs: /path/to/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # 锁定物理内存地址，防止elasticsearch内存被交换出去,也就是避免es使用swap交换分区 # bootstrap.memory_lock: true # # # # 确保ES_HEAP_SIZE参数设置为系统可用内存的一半左右 # 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. #  # 当系统进行内存交换的时候，es的性能很差 # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # # 为es设置ip绑定，默认是127.0.0.1，也就是默认只能通过127.0.0.1 或者localhost才能访问 # es1.x版本默认绑定的是0.0.0.0 所以不需要配置，但是es2.x版本默认绑定的是127.0.0.1，需要配置 # Set the bind address to a specific IP (IPv4 or IPv6): # # network.host: 192.168.0.1 # # # 为es设置自定义端口，默认是9200 # 注意：在同一个服务器中启动多个es节点的话，默认监听的端口号会自动加1：例如：9200，9201，9202... # Set a custom port for HTTP: # # http.port: 9200 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html> # # --------------------------------- Discovery ---------------------------------- # # 当启动新节点时，通过这个ip列表进行节点发现，组建集群 # 默认节点列表： # 127.0.0.1，表示ipv4的回环地址。 # [::1]，表示ipv6的回环地址 # # 在es1.x中默认使用的是组播(multicast)协议，默认会自动发现同一网段的es节点组建集群， # 在es2.x中默认使用的是单播(unicast)协议，想要组建集群的话就需要在这指定要发现的节点信息了。 # 注意：如果是发现其他服务器中的es服务，可以不指定端口[默认9300]，如果是发现同一个服务器中的es服务，就需要指定端口了。 # 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"] # # # # # 通过配置这个参数来防止集群脑裂现象 (集群总节点数量/2)+1 # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1): # # discovery.zen.minimum_master_nodes: 3 # # 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: # 一个集群中的N个节点启动后,才允许进行数据恢复处理，默认是1 # gateway.recover_after_nodes: 3 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html> # # ---------------------------------- Various ----------------------------------- # 在一台服务器上禁止启动多个es服务 # Disable starting multiple nodes on a single system: # # node.max_local_storage_nodes: 1 # # 设置是否可以通过正则或者_all删除或者关闭索引库，默认true表示必须需要显式指定索引库名称 # 生产环境建议设置为true，删除索引库的时候必须显式指定，否则可能会误删索引库中的索引库。 # Require explicit names when deleting indices: # # action.destructive_requires_name: true

 

 

 

 

 

 

 

 集群名称，默认是elasticsearch

　　输入，http://192.168.80.200:9200/

 

 

 

 

 

 

 

 默认存储在es_home/data目录下

总结

　　1、es已经为大多数参数设置合理的默认值

　　2、这个配置文件中列出来了针对生产环境下的一些重要配置

　　3、注意：这个文件是yaml格式的文件

　　　　（1）：属性顶格写，不能有空格

　　　　（2）：缩进一定不能使用tab制表符

　　　　（3）：属性和值之间的:后面需要有空格

　　　　　　　　network.host: 192.168.80.200

　　4、es的1.*版本比2.*版本，这个配置文件多了很多属性，为什么2.*版本没了呢，因为，es很多地方做了默认配置。
