集群
如果两个节点配置的 cluster.name 相同，那么启动可以自动组成集群。
默认为 my-application。
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
cluster.name: my-application
节点
集群内的节点名称不能相同
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
node.name: node-102
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
路径
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
path.data: /opt/elasticsearch-5.2.2/data
#
# Path to log files:
#
#path.logs: /path/to/logs
path.logs: /opt/elasticsearch-5.2.2/logs内存
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
#
# 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.
网络
访问外网需要绑定 0.0.0.0
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#
#http.port: 9200
http.port: 9200
#
# For more information, consult the network module documentation.
发现
# --------------------------------- 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"]
discovery.zen.ping.unicast.hosts: ["127.0.0.1", "[::1]"]
#
# 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.
