突然间，ES再也不能正常启动了。 我不知道为什么。
当我启动ES（2.3.4）时，我得到这个：
Cluster health status changed from [RED] to [YELLOW] (reason: shards started [[wa-search][3] ...]). 该安装的我的ESconfiguration：
# ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please see the documentation for further information on configuration options: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html> # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # # cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # # node.name: node-1 # # Add custom attributes to the node: # # node.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # # path.data: /path/to/data # # Path to log files: # # path.logs: /path/to/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # # bootstrap.mlockall: true # # Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory # available on the system and that the owner of the process is allowed to use this limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # # network.host: 192.168.0.1 # # Set a custom port for HTTP: # # http.port: 9200 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html> # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # # discovery.zen.ping.unicast.hosts: ["host1", "host2"] # # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1): # # discovery.zen.minimum_master_nodes: 3 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html> # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # # gateway.recover_after_nodes: 3 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html> # # ---------------------------------- Various ----------------------------------- # # Disable starting multiple nodes on a single system: # # node.max_local_storage_nodes: 1 # # Require explicit names when deleting indices: # # action.destructive_requires_name: true script.engine.groovy.inline.aggs: on threadpool.search.queue_size: 10000
最近最大的变化是切换我的硬件。 某些Adobe产品也受到此影响，BIOS更新修复了使用Adobe产品时系统崩溃的问题。 ES也可能有问题？ 这是一个英特尔7900X在华硕TUF标记1。
检查你的number_of_replicas设置，如果它是1，并且你只有一个节点，第二个碎片（1个主要，1个副本== 2）将不能被放置在任何地方，并将导致黄色的集群。
