Elasticsearch常用API

Note：以下API基于ES 5x，6x/7x可能略有不同，具体查看官方文档

ES常用API

# 查看集群node
curl "http://localhost:9200/_cat/nodes?v"

# 查看索引
curl "http://localhost:9200/_cat/indices?v"
curl "http://localhost:9200/_cat/indices/api*?v"

# 打开一个索引
curl -s -XPOST "http://localhost:9200/my-esdata/_open?pretty"

# 关闭一个索引
curl -s -XPOST "http://localhost:9200/my-esdata/_close?pretty"

# 删除一个索引
curl -XDELETE "http://localhost:9200/my-esdata"

# 设置alias
curl -X POST "localhost:9200/_aliases?pretty" -H 'Content-Type: application/json' -d'
{
    "actions" : [
        { "add" : { "index" : "test1", "alias" : "alias1" } }
    ]
}'

# 查看alias
curl "localhost:9200/_cat/aliases?v"

# thread
curl -XPUT 'http://localhost:9200/_all/_settings?preserve_existing=true' -d '{
  "index.merge.scheduler.max_thread_count" : "1",
  "index.translog.flush_threshold_size" : "512m"
}'

# 设置副本为0，可快速批量导入
curl -XPUT "localhost:9200/_settings" -d '
 {
"index":{
"number_of_replicas":0
}
}'

# 关闭合并限流，使导入更快、在导入完成后改回 merge
curl -XPUT "localhost:9200/_cluster/settings" -d '{
    "persistent" : {
        "indices.store.throttle.type" : "none" 
    }
}'

# 更改threadpool
curl -XPUT "localhost:9200/_cluster/settings" -d '{
    "thread_pool": {
		"thread_pool.index.size" : "fixed"
		"thread_pool.bulk.size" : "32"
		"thread_pool.index.queue_size" : "800"
    }
}'

# 设置刷新频率
PUT /_all/_settings
{
    "index" : {
        "refresh_interval" : "60s"
    }
}

# 查看shard分布
curl -XGET "http://localhost:9200/_cat/shards"

# 手动移动分片
curl -XPOST "http://localhost:9200/_cluster/reroute" -d '{
  "commands" : [ {
        "move" :
            {
              "index" : "my-esdata", "shard" : 3, "from_node" : "localhost", "to_node" : "10.1.1.10"
            }
        }
  ]
}'

ES Template API

# 集群设定
curl -XPUT 'http://localhost:9200/_cluster/_settings?preserve_existing=true' -d '{
"index": {
"translog.durability" : "async",
"translog.flush_threshold_size" : "1g",
"translog.sync_interval" : "60s",
"store.throttle.type": "none"
}
}'

# 设置全局shards数量
curl -XPUT 'http://localhost:9200/_all/_settings?preserve_existing=true' -d '{
  "index": {
  "number_of_shards" : "4"
  }
}'

# 查看所有template基本信息
curl -XGET "http://localhost:9200/_cat/templates?v"

# 查看指定template信息
curl -XGET "http://localhost:9200/_template/my-esdata?pretty"

# 查看所有template详细信息
curl -XGET "http://localhost:9200/_template?pretty"

# 设置my-esdata-template模板
# index name匹配为my-esdata*则使用此template
# template中参数优先与全局参数
curl -XPUT "http://localhost:9200/_template/my-esdata-template" -d '{
"template" : "my-esdata*",
  "settings" : {
  "number_of_shards" : 4,
  "number_of_replicas" : 0,
  "refresh_interval" : "60s",
  "translog.durability" : "async",
  "translog.flush_threshold_size" : "1g",
  "translog.sync_interval" : "60s",
  "store.throttle.type": "none",
  "store.throttle.max_bytes_per_sec": "100m",
  "index.routing.allocation.total_shards_per_node": "1"
  }
}'

# 设置my-test模板
# index name匹配为**则使用此template
# template中参数优先与全局参数
curl -XPUT "http://localhost:9200/_template/my-test-template" -d '{
"template" : "*my-test*",
  "settings" : {
  "number_of_shards" : 4,
  "number_of_replicas" : 0,
  "refresh_interval" : "60s",
  "translog.durability" : "async",
  "translog.flush_threshold_size" : "1g",
  "translog.sync_interval" : "60s",
  "store.throttle.type": "none",
  "store.throttle.max_bytes_per_sec": "100m",
  "index.routing.allocation.total_shards_per_node": "1"
