Elasticsearch 认证模拟题 - 17

news 2025/6/28 8:51:37

这两道题目非常具有代表性，分别是跨集群复制和跨集群检索，需要相应的许可这里在虚拟机上搭建集群完成这两道题目，这里补充一下 elasticsearch 和 kibana 的配置文件

# elasticsearch.yml
cluster.name: cluster2
node.name: cluster2-node
path.data: /home/jie/es8/cluster2/data
path.logs: /home/jie/es8/cluster2/logs
bootstrap.memory_lock: true
network.host: 192.168.78.10
http.port: 9202
transport.port: 9302
discovery.seed_hosts: ["cluster2-node"]
cluster.initial_master_nodes: ["cluster2-node"]
xpack.security.enabled: false# jvm.options
-Xms1g
-Xmx1g# kibana.yml
server.port: 5603
server.host: "0.0.0.0"
elasticsearch.hosts: ["http://192.168.78.10:9202"]

一、题目

跨集群查询

# 向 cluster_one 写入数据
POST test/_bulk
{"index": {}}
{"cluster_name": "cluster_one"}# 向 cluster_two写入数据
POST test/_bulk
{"index": {}}
{"cluster_name": "cluster_two"}

1.1 考点

跨集群查询配置
跨集群查询检索
节点角色

这里需要注意的是节点角色需要有 remote_cluster_client 角色

1.2 答案

# 建立远程连接
PUT _cluster/settings
{"persistent": {"cluster": {"remote": {"cluster_one": {"seeds": ["192.168.78.10:9301"]},"cluster_two": {"seeds": ["192.168.78.10:9302"]}}}}
}# 查看远程连接信息
GET _remote/info# 搜索 cluster_one 和 cluster_two 集群的 test 索引
POST cluster_one:test,cluster_two:test/_search

二、题目

跨集群复制

2.1 考点

许可证适用：Stack Management -> License Management -> Start a 30-day trial
跨集群复制

2.2 答案

创建远程连接集群

PUT _cluster/settings
{"persistent": {"cluster": {"remote": {"cluster_one": {"seeds": ["192.168.78.10:9301"]},"cluster_two": {"seeds": ["192.168.78.10:9302"]}}}}
}
