docker ElasticSearch 7.3 多机器无法组成集群

error1

bash

如果你用的docker部署多机器集群就会提示这个错误

解决方法

elasticsearch.yml 中添加

network.publish_host: 192.168.9.52（内网ip）

error2

bash

error1:
elasticsearch master not discovered yet: have discovered


error2:
Elastic master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes

error3:
Master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster

部署elasticsearch:7.11.2 集群遇到如上 error。只因我所有的节点都是复制的同一个 elasticsearch/config,，所以部分uuid相同，无法通信。

解决方法：重新生成一份，elasticsearch/config 这个目录的文件就行了

error3

bash

failed to initialize SSL TrustManager - not permitted to read truststore file

因为证书没有读取权限, 解决方法：

bash

sudo chmod 775 elastic-stack-ca.p12
sudo chmod 775 elastic-certificates.p12

error4

组成集群的 data/nodes 目录不能copy, 必须每个机器单独生成
