ElasticSerach Url报错503
删除默认目录的文件
查了很多资料，再看自己的没毛病 E版本 elasticsearch-7.4.2-x86_64.rpm
配置文件：
cluster.name: hang
node.name: node-1
node.master: true
transport.host: 192.168.44.192
transport.tcp.port: 9300
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.44.192","192.168.44.193"]
cluster.initial_master_nodes: 192.168.44.192
http.cors.enabled: true
http.cors.allow-origin: "*"
discovery.zen.minimum_master_nodes: 2
查看 http://192.168.44.192:9200/ 没问题

{ "error" : { "root_cause" : [ { "type" : "master_not_discovered_exception", "reason" : null } ], "type" : "master_not_discovered_exception", "reason" : null }, "status" : 503 }
删除默认配置文件之前的配置信息
rm -rf /var/log/elasticsearch/*
rm -rf /var/lib/elasticsearch/* #尤其是这个下面的nodes文件
完事
