报错分析：
在启动ElasticSearch的过程中爆出了以下错误：
ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
解决方案:
ip替换host1等，多节点请添加多个ip地址，单节点可写按默认来
#配置以下三者，最少其一
#[discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes]
cluster.initial_master_nodes: ["node-1"] #这里的node-1为node-name配置的值
