我已经在2个不同的服务器上安装了2个ES podman容器(主服务器和辅助服务器)
主elasticsearch.yml配置:
network.host: 0.0.0.0
cluster.name: xyz-es
node.name: node-primary # On the primary, use 'node-primary', and 'node-secondary' on the secondary
path.data: /usr/share/elasticsearch/data
discovery.seed_hosts: ["172.16.211.99", "172.18.205.99"] # ["ip_of_primary", "ip_of_secondary"]
cluster.initial_master_nodes: ["node-primary", "node-secondary"]
xpack.security.enabled: false

辅助elasticsearch.yml配置
network.host: 0.0.0.0
cluster.name: xyz-es
node.name: node-secondary # On the primary, use 'node-primary', and 'node-secondary' on the secondary
path.data: /usr/share/elasticsearch/data
discovery.seed_hosts: ["172.16.211.99", "172.18.205.99"] # ["ip_of_primary", "ip_of_secondary"]
cluster.initial_master_nodes: ["node-primary", "node-secondary"]
xpack.security.enabled: false

然而,辅助节点无法从主服务器复制数据,当检查日志时,辅助Elasticsearch节点能够完成与主节点的初始握手,但随后后续连接失败,并出现NoRouteToHostException错误。

如果查看日志,可以看到辅助服务器将联系主服务器,主服务器将使用容器内部IP进行响应,该IP无法通过网络访问

如何强制辅助节点使用seed_hosts IP而不是响应IP?或者我缺少另一个配置,感谢任何人的帮助。
1条答案
按热度按时间pu82cl6c1#
找到解决方案:
将publish_host添加到配置中,让其他节点调用IP,而不是默认主机,在本例中,localhost默认为容器IP
