重置备份
curl -XPUT "http://localhost:9200/_settings" -d'
{
"number_of_replicas" : 2
}'
2. 安全关闭
curl -XPUT
http://localhost:9200/_cluster/settings -d'
{
"transient" : {
"cluster.routing.allocation.enable" : "none"
}
}'
curl -XPUT http://
localhost:9200/_cluster/settings -d'
{
"transient" : {
"cluster.routing.allocation.enable" : "all"
}
}'
3. 关闭自动刷新
大批量插入之前
# curl -XPUT
http://127.0.0.1:9200/*-d'
{
"settings" : {
"refresh_interval": "-1"
}
}'
大批量插入之后改回1
4. 索引别名
curl -XPOST
'http://localhost:9200/_aliases' -d '
{
"actions": [
{"remove":
{"index": "*", "alias":
"*"}},
{"add":
{"index":"*", "alias": " *"}}
]
}'
5. 手动分配分片
分配一个未分配的分片到指定节点。可以指定索引名和分片号。node参数指定分配到那个节点。allow_primary参数可以强制分配主分片，不过这样可能导致数据丢失。
curl -s
"http://localhost:9200/_cat/shards" | grep UNASSIGNED
curl
'localhost:9200/_nodes/process?pretty'
curl -XPOST
'localhost:9200/_cluster/reroute' -d '{
"commands" : [ {
"allocate" : {
"index" :
"your_index_name",
"shard" : 1 (share
index),
"node" :
"AfUyuXmGTESHXpwi4OExxx(NODE 编码)",
"allow_primary" :
true
}
}
]
}'
