elasticsearch - guide - 更新集群设置的 API

可以修改整个集群的特定设置. 设置的修改可以保存 (重启后仍然生效) 或者是临时的 (不会保留到下次重启后). 请看示例:

curl -XPUT localhost:9200/_cluster/settings -d '{
    "persistent" : {
        "discovery.zen.minimum_master_nodes" : 2
    }
}'

或者:

curl -XPUT localhost:9200/_cluster/settings -d '{
    "transient" : {
        "discovery.zen.minimum_master_nodes" : 2
    }
}'

下面是可修改的设置列表：

discovery.zen.minimum_master_nodes
index.shard.recovery.concurrent_streams
cluster.routing.allocation.node_initial_primaries_recoveries, cluster.routing.allocation.node_concurrent_recoveries
cluster.routing.allocation.cluster_concurrent_rebalance
cluster.routing.allocation.awareness.attributes
cluster.routing.allocation.awareness.force.*
cluster.routing.allocation.disable_allocation
cluster.routing.allocation.disable_replica_allocation
cluster.routing.allocation.include.*
cluster.routing.allocation.exclude.*
indices.cache.filter.size
indices.ttl.interval
indices.recovery.file_chunk_size, indices.recovery.translog_ops, indices.recovery.translog_size, indices.recovery.compress, indices.recovery.concurrent_streams, indices.recovery.max_size_per_sec.

Logger 的值可以通过 logger. prefix 设置. 还可以修改更多的设置项.

可以用 curl -XGET localhost:9200/_cluster/settings 来查看有哪些设置项.
