新建用户es，因为elasticsearch不能在root用户下进行
cluster.name: es-cluster #设置集群的名称
node.name: es-node #修改当前节点的名称
path.data: /home/es/elasticsearch/elasticsearch/data #修改数据路径
path.logs: /home/es/elasticsearch/elasticsearch/logs #修改日志路径
bootstrap.memory_lock: false #设置 ES 节点允许内存交换
bootstrap.system_call_filter: false #禁用系统调用过滤器
network.host: localhost #设置当前主机名称
discovery.zen.ping.unicast.hosts: ["localhost"] #设置集群的主机列表,若此时有多个集群应在此列出，此时仅为单节点故只列本机
虚拟机设置开启主机访问
-
在虚拟机网络中设置虚拟网络编辑器把主机IP地址加入vment8的NAT设置中
-
此时便可在主机中的elasticsearch head中查看集群
