ELK之 kibana 报错master_not_discovered_exception] null or kibana-Request Timeout after 30000ms

ELK之 kibana7.7 elasticsearch 7.7 报错master_not_discovered_exception] null or kibana-Request Timeout after 30000ms

{“type”:“log”,"@timestamp":“2020-05-18T13:34:53Z”,“tags”:[“warning”,“savedobjects-service”],“pid”:4674,“message”:“Unable to connect to Elasticsearch. Error: Request Timeout after 30000ms”}

{“type”:“log”,"@timestamp":“2020-05-18T13:37:10Z”,“tags”:[“warning”,“savedobjects-service”],“pid”:5075,“message”:“Unable to connect to Elasticsearch. Error: [master_not_discovered_exception] null”}

解决思路：
原因是由elasticsearch.yml的配置未配置正确引起的
vim config/elasticsearch.yml

node.name: node-1
cluster.initial_master_nodes: [“node-1”]
:wq

后重启es后，kibana连接就正常了！
