"commands" : [{
"move" : {
"index" : "info-test", "shard" : 3,
"from_node" : "EsNode3@189.39.172.103",
"to_node" : "EsNode2@189.39.172.103"
}
}]
}'
?
限制每個(gè)索引在每個(gè)實(shí)例上的分片個(gè)數(shù)
curl -XPUT?--tlsv1.2 --negotiate -k -v -u :?'https://http:httpport/myindex/_settings?pretty' -H 'Content-Type:application/json' -d '{"index.routing.allocation.total_shards_per_node":"2"}'
?
Shrink操作
1、目前集群默認(rèn)設(shè)置的是同一臺(tái)主機(jī)不能存放同一主副本分片，需先在后臺(tái)關(guān)閉該設(shè)置。防止分片自動(dòng)均衡，關(guān)閉分片分配。
curl -XPUT 'http://127.0.0.1:24100/_cluster/settings?pretty'-H 'Content-Type:application/json' -d '{"transient":{"cluster.routing.allocation.same_shard.host":false,"cluster.routing.allocation.enable":"none"}}'
2、將索引標(biāo)記為只讀，且所有的分片副本都遷移到實(shí)例名為EsNode1@IP的實(shí)例上。注意：“所有的分片副本”不指定索引的全部分片，無(wú)論主分片還是副本分片，任意一個(gè)就行。
curl -XPUT?"http://127.0.0.1:24100/jjj.pm_20190224/_settings" -H 'Content-Type:?application/json' -d'{
"settings": {???
"index.routing.allocation.require._name": "EsNode1@IP",
"index.blocks.write": true
? }
}'
3、執(zhí)行完上述命令之后，分片開(kāi)始遷移，執(zhí)行下列命令，查看分片是否遷移完成。
curl –XGET?http://127.0.0.1:24100/_cat/shards?v?| grep jjj.pm_20190224
4、分片轉(zhuǎn)移完成之后，查看集群是否green。
curl -XGET http://127.0.0.1:24100/_cluster/health?pretty
5、等待分片遷移完成之后，集群green后，我們就可以執(zhí)行Shrink操作了。
curl -XPOST "http://127.0.0.1:24100/jjj.pm_20190224/_shrink/ jjj.pm_20190224_new" -H 'Content-Type: application/json' -d'{
"settings": {
"index.number_of_replicas": 1,
"index.number_of_shards": 41,
"index.codec": "best_compression"
}
}'
以上代碼將創(chuàng)建含有一個(gè)41個(gè)主分片和一個(gè)副本分片的目的索引jjj.pm_20190224_new。
6、刪除原來(lái)的索引
curl -XDELETE http://127.0.0.1:24100/jjj.pm_20190224?pretty
7、并為新建的索引設(shè)置別名，別名設(shè)置為原來(lái)索引名稱。
curl -XPOST 'http://127.0.0.1:24100/_aliases?pretty' -H 'Content-Type: application/json' -d' {
"actions":
[{"add":{"index": "jjj.pm_20190224_new","alias":"jjj.pm_20190224"}}]}'
8、查看集群狀態(tài)，green之后，還原參數(shù)。
curl -XPUT 'http://127.0.0.1:24100/_cluster/settings?pretty'-H 'Content-Type:application/json' -d
'{"transient":{"cluster.routing.allocation.same_shard.host":true,"cluster.routing.allocation.enable":"all"}}'
?
?
_template操作???
查看模板
curl -XGET –tlsv1.2 –negotiate -k -u : "https://ip:port/_template/template_1?pretty"
設(shè)置/修改模板
curl -XPUT –tlsv1.2 –negotiate -k -u : "https://ip:port/_template/template_1" -H 'Content-Type: application/json' -d '{ "template" : "*", "order" : 0, "settings" : { "number_of_shards" : 1 }, "mappings" : { "type1" : { "_source" : { "enabled" : false } } } }'
?
SQL插件常用用法???
curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json" ?-d 'SELECT * FROM test_index'
如上所示，三個(gè)地方需要注意：
1.????????SQL語(yǔ)句使用?”-XPOST”
2.????????Ip:port后需要跟?”_sql”
3.????????-d后直接跟SQL語(yǔ)句
全局查詢：curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index'
單關(guān)鍵字查詢：curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index where content="美國(guó)"'
多關(guān)鍵字查詢：
curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index where content="美國(guó)" and content="中國(guó)"'
curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index where content="美國(guó)" or content="中國(guó)"'
單字段排序：
curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index where content="美國(guó)" or content="中國(guó)" ORDER BY _score DESC'
多字段排序：
curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index where (content1="美國(guó)" or content1="中國(guó)") ORDER BY content2 ASC, _score DESC'
模糊查詢：
curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index where content1 like "喀*湖"'
限制輸出個(gè)數(shù)：
curl -XPOST?–tlsv1.2?–negotiate -k -u : 'https://ip:port/_sql?pretty' -H "Content-Type: application/json"? -d 'SELECT * FROM test_index limit 2'?
?
解釋分片命令???
curl -XGET --negotiate -k -u : "https://127.0.0.1:24100/_cluster/allocation/explain?pretty" -d '{
"index": "indexname",
"shard": 17,
"primary": true
}'
?
bulk操作???
讀取文件夾下的文件，通過(guò)bulk寫(xiě)入：
for file_each in `ls`
do
curl -XPOST?–tlsv1.2 --negotiate -k -v -u : 'https://127.0.0.1:24100/_bulk?pretty' -H 'Content-Type:application/json' --data-binary @${file_each}
done
