• 示例elasticsearch.yml 配置（注释内容留下以便学习）

# ======================== Elasticsearch Configuration =========================
# ---------------------------------- Cluster -----------------------------------

# Use a descriptive name for your cluster:
#为集群使用描述性名称:
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
# 为节点使用描述性名称:
node.name: node-1
#
# Add custom attributes to the node:
#向节点添加自定义属性:
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#存储数据的目录路径(用逗号分隔多个位置): 默认当前路径下
#path.data: /path/to/data
#
# Path to log files:
#日志文件路径 默认当前路径下
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#启动时锁定内存: 不开启会影响性能
bootstrap.memory_lock: 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.
#确保将堆大小设置为可用内存的一半左右，并且进程的所有者被允许使用它极限。当系统交换内存时，Elasticsearch的性能很差。
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#将绑定地址设置为特定的IP (IPv4或IPv6):
network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#为HTTP设置自定义端口:
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#当这个节点启动时，传递一个初始的主机列表来执行发现:
#主机的默认列表为 ["127.0.0.1", "[::1]"]
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#使用主节点的初始集合引导集群:
cluster.initial_master_nodes: ["node-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#整个集群重启后的块初始恢复，直到N个节点启动:
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#删除索引时需要显式名称:
#action.destructive_requires_name: true
