elasticsearch運維常用命令

elasticsearch內存設置：
export ES_HEAP_SIZE=10g

或者啓動的時候設置參數，確保Xmx和Xms大小相等:
./bin/elasticsearch -Xmx10g -Xms10g

啓動進程：
./elasticsearch -d

查看es進程：
ps -ef | grep elastic

kill進程：
kill pid

cat系列
_cat系列提供了一系列查詢elasticsearch集羣狀態的接口，可以通過執行
curl -XGET localhost:9200/_cat獲取所有_cat系列的操作：
/_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}
可以後面加一個v，讓輸出內容表格顯示錶頭，命令示例：
命令示例：
顯示所有索引：
curl '10.116.182.65:9200/_cat/indices?v'   
顯示線程信息：
curl '10.110.79.24:9200/_cat/thread_pool?v'
顯示結點：
curl '10.110.79.24:9200/_cat/nodes'

cluster系列
1、查詢設置集羣狀態
curl -XGET localhost:9200/_cluster/health?pretty=true
pretty=true 表示格式化輸出
level=indices 表示顯示索引狀態
level=shards 表示顯示分片信息

2、curl -XGET 10.116.182.65:9200/_cluster/stats?pretty=true
顯示集羣系統信息，包括CPU JVM等等

3、curl -XGET 10.116.182.65:9200/_cluster/state?pretty=true
集羣的詳細信息。包括節點、分片等

3、curl -XGET 10.116.182.65:9200/_cluster/pending_tasks?pretty=true
獲取集羣堆積的任務

3、修改集羣配置
舉例：
curl -XPUT localhost:9200/_cluster/settings -d '{
    "persistent" : {
        "discovery.zen.minimum_master_nodes" : 2
    }
}'
transient 表示臨時的，persistent表示永久的

4、curl -XPOST 'localhost:9200/_cluster/reroute' -d 'xxxxxx'
對shard的手動控制

5、關閉節點
關閉指定192.168.1.1節點
curl -XPOST 'http://192.168.1.1:9200/_cluster/nodes/_local/_shutdown'
curl -XPOST 'http://localhost:9200/_cluster/nodes/192.168.1.1/_shutdown'
關閉主節點
curl -XPOST 'http://localhost:9200/_cluster/nodes/_master/_shutdown'
關閉整個集羣
curl -XPOST 'http://localhost:9200/_shutdown?delay=10s'
curl -XPOST 'http://localhost:9200/_cluster/nodes/_shutdown'
curl -XPOST 'http://localhost:9200/_cluster/nodes/_all/_shutdown'
delay=10s表示延遲10秒關閉

nodes系列
1、查詢節點的狀態
curl -XGET 'http://localhost:9200/_nodes/stats?pretty=true'
curl -XGET 'http://localhost:9200/_nodes/192.168.1.2/stats?pretty=true'
curl -XGET 'http://localhost:9200/_nodes/process'
curl -XGET 'http://localhost:9200/_nodes/_all/process'
curl -XGET 'http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/jvm,process'
curl -XGET 'http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/info/jvm,process'
curl -XGET 'http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/_all
curl -XGET 'http://localhost:9200/_nodes/hot_threads

索引操作
創建索引：
curl -XPUT 'http://10.202.153.58:9200/fvp~oncarsummary/oncarsummary'
curl -XPUT 'http://10.202.153.58:9200/fvp~onaviationtasksummary/onaviationtasksummary'

查看所有索引 ：
curl '10.202.34.211:9200/_cat/indices?v'  
 
索引數據
curl -XPOST 'http://localhost:9200/{index}/{type}/{id}' -d'{"a":"avalue","b":"bvalue"}'
curl -XPUT 'http://localhost:9200/{index}/{type}/{id}' -d'{"a":"avalue","b":"bvalue"}'

查詢索引：
curl -XGET '10.202.34.211:9200/fvp~onaviationtasksummary/fvp/_search?q=*&pretty'
curl -XGET '10.202.34.211:9200/fvp~oncarsummary/fvp/_search?q=*&pretty'

GET /megacorp/employee/_search //查詢全部員工
GET /megacorp/employee/_search?q=last_name:Smith //查詢last_name爲Smith的員工
curl -XGET http://10.110.79.22:9200/new-sgs-rbil-core-system-dds-next-tcs-server-core-dcn-2017-06-27/record/_search?pretty -d '{
