elasticsearch错题本

一，集群启动报错

[node-1] master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes [node-1, node-2, node-3, node-4, node-5, node-6] to bootstrap a cluster: have discovered [{node-1}{hHLczlpgRrilhz4YckzPvw}{vJw3MlmtQ_WsRNkijTAJpg}{dm-storm01}{10.217.134.23:9300}{dilm}{ml.machine_memory=135353155584, rack=rack1, xpack.installed=true, box_type=hot, ml.max_open_jobs=20}]; discovery will continue using [10.217.134.32:9300, 10.217.134.31:9300, 10.217.134.30:9300, 10.217.109.155:9300, 10.217.109.156:9300] from hosts providers and [{node-1}{hHLczlpgRrilhz4YckzPvw}{vJw3MlmtQ_WsRNkijTAJpg}{dm-storm01}{10.217.134.23:9300}{dilm}{ml.machine_memory=135353155584, rack=rack1, xpack.installed=true, box_type=hot, ml.max_open_jobs=20}] from last-known cluster state; node term 0, last-accepted version 0 in term 0

discovery.seed_hosts: ["dm-storm01:9300","dm-storm02:9300","dm-storm03:9300","dm-storm04:9300","dm-storm05:9300","dm-storm06:9300"]
           

原因是这不是第一次搭集群，之前的集群和当前集群使用相同的data目录，导致报错，清空data目录就可以。

二，开启xpack后执行设置密码的命令报错

Connection failure to: http://192.168.88.161:19200/_security/_authenticate?pretty failed: Connection refused (Connection refused)
           

原因：集群还未启动成功，要等几分钟后重试
