这些东西在官网上都有。因为经常用，在这里做个笔记：

cluster updating：

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

<pre name="code" class="javascript">curl -XPUT localhost:9200/_cluster/settings -d '{    "transient" : {        "discovery.zen.minimum_master_nodes" : 2    }}'

{    "persistent" : {},    "transient" : {        "discovery.zen.minimum_master_nodes" : "2"    }}'

update indices setting:

</pre><pre name="code" class="javascript">curl -XPUT 'localhost:9200/my_index/_settings' -d '{    "index" : {        "number_of_replicas" : 4    }}'
