Elasticseach调增部分参数
1、调整参数
curl -XPUT 'http://172.20.43.6:9200/_cluster/settings' -d '{
"persistent": {
"indices.recovery.max_bytes_per_sec" : "50mb",
"threadpool.index.type": "fixed",

"index.translog.durability": "async",
"index.translog.flush_threshold_size": "600MB",
"index.translog.flush_threshold_ops": 500000
},
"transient": {

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",

}
}'
–节点下线时，把所有后缀为 -2的从集群中排除
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
}
}'
—批量指定节点下线

shard的移动
curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
