使用bulk API 增加入庫速度
初次索引的時候，把 replica 設置為 0
增大 threadpool.index.queue_size 1000
增大 indices.memory.index_buffer_size: 20%
index.translog.durability: async –這個可以異步寫硬盤，增大寫的速度
增大 index.translog.flush_threshold_size: 600MB
增大 index.translog.flush_threshold_ops: 500000

curl -XPOST '127.0.0.1:9200/_cluster/settings' -d '{"transient" : {"index.indexing.slowlog.threshold.index.warn": "10s","index.indexing.slowlog.threshold.index.info": "5s","index.indexing.slowlog.threshold.index.debug": "2s","index.indexing.slowlog.threshold.index.trace": "500ms","index.indexing.slowlog.level": "info","index.indexing.slowlog.source": "1000","indices.memory.index_buffer_size": "20%"}}'

curl -XPOST '127.0.0.1:9200/_cluster/settings' -d '{"transient" : {"index.search.slowlog.threshold.query.warn": "10s","index.search.slowlog.threshold.query.info": "5s","index.search.slowlog.threshold.query.debug": "2s","index.search.slowlog.threshold.query.trace": "500ms","index.search.slowlog.threshold.fetch.warn": "1s","index.search.slowlog.threshold.fetch.info": "800ms","index.search.slowlog.threshold.fetch.debug": "500ms","index.search.slowlog.threshold.fetch.trace": "200ms"}}'

–節點下線時，把所有后綴為 -2的從集群中排除

curl -XPUT http://127.0.0.1:9200/_cluster/settings { "transient" : {"cluster.routing.allocation.enable" : "all", "cluster.routing.allocation.exclude._name":".*-2"}}

curl -XPUT ip:9200/_cluster/settings -d '{"transient": {"logger.discover": "DEBUG" }"persistent": {"discovery.zen.minimum_master_nodes": 2} }'

—批量指定節點下線

curl -XPUT 127.0.0.1:9200/_cluster/settings -d '{"transient": {"cluster.routing.allocation.exclude._name": "atest11-2,atest12-2,anatest13-2,antest14-2" }}' curl -XPUT 127.0.0.1:9200/_cluster/settings -d '{"transient": {"cluster.routing.allocation.exclude._name": "test_aa73_2,test_aa73" }}' curl -XPUT 127.0.0.1:9200/_cluster/settings -d '{"transient": {"cluster.routing.allocation.exclude._name": "" }}' curl -XPUT 127.0.0.1:9200/_cluster/settings -d '{"transient": {"cluster.routing.allocation.cluster_concurrent_rebalance": 10}}'

curl -XPUT 127.0.0.1:9200/_cluster/settings -d '{"transient": {"indices.store.throttle.type": "none","index.store.type": "niofs","index.cache.field.type": "soft","indices.store.throttle.max_bytes_per_sec": "500mb","index.translog.flush_threshold_size": "600MB","threadpool.flush.type": "fixed","threadpool.flush.size": 32,"threadpool.flush.queue_size": 1000}}'

curl -XPUT 127.0.0.1:9200/_cluster/settings -d '{"transient": {"index.indexing.slowlog.level": "warn" }}'

curl -XGET 127.0.0.1:9200/_cluster/health?level=shardscurl -XGET 127.0.0.1:9200/_cluster/settings?prettycurl -XGET 127.0.0.1:9200/_cluster/pending_tasks?prettycurl -XGET 127.0.0.1:9200/_cat/aliasescurl -XGET 127.0.0.1:9200/_cat/pluginscurl -XGET 127.0.0.1:9200/_cat/nodes/_cat/allocation /_cat/shards /_cat/shards/{index} /_cat/master /_cat/nodes /_cat/indices /_cat/indices/{index} /_cat/segments /_cat/segments/{index} /_cat/count /_cat/count/{index} /_cat/recovery /_cat/recovery/{index} /_cat/health /_cat/pending_tasks /_cat/aliases /_cat/aliases/{alias} /_cat/thread_pool /_cat/plugins /_cat/fielddata /_cat/fielddata/{fields}

shard的移動 curl -XPOST 'localhost:9200/_cluster/reroute' -d '{"commands" : [ {"move" :{"index" : "test_aa_20160529", "shard" : 4,"from_node" : "node1", "to_node" : "node2"}},{"allocate" : {"index" : "test", "shard" : 1, "node" : "node3"}}] }'

curl -XPUT 127.0.0.1:9200/_cluster/settings -d ' {"transient": {"logger.indices.recovery": "DEBUG"} }' curl -XPUT 127.0.0.1:9200/_cluster/settings -d ' {"transient": {"cluster.routing.allocation.node_initial_primaries_recoveries": "100" } }'

curl -XPOST '127.0.0.1:9200/_cluster/settings' -d '{"transient" : {"indices.memory.index_buffer_size": "20%"}}'

curl -XPOST '127.0.0.1:9200/_cluster/settings' -d '{"transient" : {"index.indexing.slowlog.level" : "info" }}'
