安装
yum localinstall elasticsearch-6.1.1.rpm -y
mkdir -p /elk/{data,logs} && chown -R elasticsearch.elasticsearch /elk
配置
grep '^[a-Z]' /etc/elasticsearch/elasticsearch.yml
cluster.name: yoho8elk #ELK的集群名称，名称相同即属于是同一个集群
node.name: manager-node-1 #本机在集群内的节点名称ode-1
path.data: /elk/data #数据保存目录
path.logs: /elk/logs #日志保存目录
bootstrap.memory_lock: true #服务启动的时候锁定足够的内存，防止数据写入swap,可能会导致云主机报错.可以不填写.
network.host: 0.0.0.0 #监听 10.0.1.0网段的
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.1.100", "10.0.1.24"]
修改内存限制，并同步配置文件：

node.name: test-web04-node-2
path.data: /elk/data
path.logs: /elk/logs
bootstrap.memory_lock: true #在云主机上加上这个参数可能会报错。

http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.1.100", "10.0.1.24"]
