关于一些es操作指南

查看节点列表

curl -XGET -u elastic:xxxxx 134.84.22.7:9200/_cat/nodes

查看节点详情

curl -u elastic:xxxxx http://134.84.22.7:9200/_nodes/process?pretty

查看节点健康状态

curl -u elastic:xxxxx http://134.84.22.9:9200/_cat/health?v

查看shards 分片分配情况和索引状态

curl -XGET -s -u elastic:xxxxx http://localhost:9200/_cat/shards

查看集群错误原因和索引

curl -u elastic:xxxxx 'localhost:9200/_cluster/allocation/explain?pretty'

调整恢复线程 为 8

curl -X PUT -u elastic:xxxxx http://localhost:9200/_cluster/settings -H 'Content-Type: application/json' -d'
{
    "persistent": {
        "cluster.routing.allocation.node_concurrent_recoveries": 8,
        "indices.recovery.max_bytes_per_sec": "40mb"
    }
}
'

从有数据的节点进行索引恢复

curl -H 'Content-Type: application/json'
-s -u elastic:xxxxx -XPOST '127.0.0.1:9200/_cluster/reroute?pretty' -d '{
"commands" : [ {
"allocate_stale_primary" :
{
"index" : "xxxxx-2022.04.02", "shard" : 0,
"node" : "nAihxBOdR2Gkm2vFeHKvEA",
"accept_data_loss" : true
}
}
]
}'
