静态Elasticsearch设置
示例
Elasticsearch使用YAML（又一种标记语言）配置文件，可以在默认的Elasticsearch目录中找到该文件（RPM和DEB安装会更改此位置）。
您可以在中设置基本设置config/elasticsearch.yml：
# Change the cluster name. All nodes in the same cluster must use the same name!
cluster.name: my_cluster_name
# Set the node's name using the hostname, which is an environment variable!
# This is a convenient way to uniquely set it per machine without having to make
# a unique configuration file per node.
node.name: ${HOSTNAME}
# ALL nodes should set this setting, regardless of node type
path.data: /path/to/store/data
# This is a both a master and data node (defaults)
node.master: true
node.data: true
# This tells Elasticsearch to bind all sockets to only be available
# at localhost (default)
network.host: _local_
