三台es实例的集群日志出现org.elasticsearch.discovery.MasterNotDiscoveredException问题

解决方法

（1）确认hostname配置正确

echo ${HOSTNAME}

（2）确认elasticsearch.yml文件下面配置项正确

# 三台实例保证相同
cluster.name: my-cluster
# 设置成对应的 ${HOSTNAME}
node.name: es-01
# 设置成三台实例的 ${HOSTNAME}
discovery.seed_hosts: ["es-01", "es-02", "es-03"]
cluster.initial_master_nodes: ["es-01", "es-02", "es-03"]

（3）如果上面都确认过了，还是出现该错误，那么再调整日志级别，打印更详细的日志

logger.org.elasticsearch.cluster.coordination.ClusterBootstrapService: TRACE
logger.org.elasticsearch.discovery: TRACE

我的机器由2网卡enp0s3、enp0s8，我通过调整日志级别后，在日志中发现es自动发现集群node从各个机器的enp0s3上10.0.2.15的IP上发现，应该是network.host绑定0.0.0.0导致的

# 增加 network.publish_host 配置
network.publish_host: 192.168.1.100
