写在前面

本文看下跨集群搜索相关内容。

1：实战

1.1：创建集群

bin/elasticsearch -E node.name=cluster0node -E cluster.name=cluster0 -E path.data=cluster0_data -E discovery.type=single-node -E http.port=9200 -E transport.port=9300
bin/elasticsearch -E node.name=cluster1node -E cluster.name=cluster1 -E path.data=cluster1_data -E discovery.type=single-node -E http.port=9201 -E transport.port=9301
bin/elasticsearch -E node.name=cluster2node -E cluster.name=cluster2 -E path.data=cluster2_data -E discovery.type=single-node -E http.port=9202 -E transport.port=9302

1.2：设置各个集群支持跨集群搜索

curl -XPUT "http://localhost:9200/_cluster/settings" -H 'Content-Type: application/json' -d'
{"persistent":{"cluster":{"remote":{"cluster0":{"seeds":["127.0.0.1:9300"],"transport.ping_schedule":"30s"},"cluster1":{"seeds":["127.0.0.1:9301"],"transport.compress":true,"skip_unavailable":true},"cluster2":{"seeds":["127.0.0.1:9302"]}}}}}'curl -XPUT "http://localhost:9201/_cluster/settings" -H 'Content-Type: application/json' -d'
{"persistent":{"cluster":{"remote":{"cluster0":{"seeds":["127.0.0.1:9300"],"transport.ping_schedule":"30s"},"cluster1":{"seeds":["127.0.0.1:9301"],"transport.compress":true,"skip_unavailable":true},"cluster2":{"seeds":["127.0.0.1:9302"]}}}}}'curl -XPUT "http://localhost:9202/_cluster/settings" -H 'Content-Type: application/json' -d'
{"persistent":{"cluster":{"remote":{"cluster0":{"seeds":["127.0.0.1:9300"],"transport.ping_schedule":"30s"},"cluster1":{"seeds":["127.0.0.1:9301"],"transport.compress":true,"skip_unavailable":true},"cluster2":{"seeds":["127.0.0.1:9302"]}}}}}'

1.3：创建测试数据

curl -XPOST "http://localhost:9200/users/_doc" -H 'Content-Type: application/json' -d'
{"name":"user1","age":10}'curl -XPOST "http://localhost:9201/users/_doc" -H 'Content-Type: application/json' -d'
{"name":"user2","age":20}'curl -XPOST "http://localhost:9202/users/_doc" -H 'Content-Type: application/json' -d'
{"name":"user3","age":30}'
