Elasticsearch重启前禁止分片移动的方法

重启集群前，先设置集群停止分片移动：

curl -XPUT http://localhost:9200/_cluster/settings -d '{ "transient" : { "cluster.routing.allocation.enable" : "none" } }'

重启之后，恢复分片自动分配：

curl -XPUT http://localhost:9200/_cluster/settings -d '{ "transient" : { "cluster.routing.allocation.enable" : "all" } }'
