已解决

以下所有内容基于elasticsearch7.1，（2019-09-23）

#### 异常一： ####

OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

方法：ES7期望对应jdk较高版本。

#### 异常二： ####

master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes [node-1, node-2] to bootstrap a cluster: have discovered []; discovery will continue using [39.96.204.209:9300, 39.96.53.204:9300] from hosts providers and [{node-2}{XtFVzflPRjqVF-3xV0WIrg}{SaqRZPFqTKC_36E_PycKsw}{172.17.133.188}{172.17.133.188:9300}{ml.machine_memory=1927254016, xpack.installed=true, ml.max_open_jobs=20}] from last-known cluster state; node term 0, last-accepted version 0 in term 0

检测不到主节点master节点；

请模仿我配置文件，读取注释，\#\# elasticsearch.yml

# ======================== 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 consult the documentation for further information on configuration options:
    # https://www.elastic.co/guide/en/elasticsearch/reference/index.html
    #
    # ---------------------------------- Cluster -----------------------------------
    #
    # Use a descriptive name for your cluster:
    #
    cluster.name: myes
    node.master: true
    #
    # ------------------------------------ Node ------------------------------------
    #
    # Use a descriptive name for the node:
    #
    node.name: node-1
    #
    # Add custom attributes to the node:
    #
    #node.attr.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.memory_lock: true
    #
    # Make sure that the heap size 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: 0.0.0.0
    #和其他程序通信
    network.publish_host: 39.96.53.204
    #
    # Set a custom port for HTTP:
    #
    http.port: 9200
    transport.tcp.port: 9300
    #
    # For more information, consult the network module documentation.
    #
    http.cors.enabled: true
    http.cors.allow-origin: "*"
    # --------------------------------- Discovery ----------------------------------
    #
    # Pass an initial list of hosts to perform discovery when this node is started:
    # The default list of hosts is ["127.0.0.1", "[::1]"]
    #
    discovery.seed_hosts: ["39.96.199.161", "39.96.53.204"]
    #
    # Bootstrap the cluster using an initial set of master-eligible nodes:
    #
    cluster.initial_master_nodes: ["node-1","node-2"]
    #
    # For more information, consult the discovery and cluster formation module documentation.
    #
    # ---------------------------------- Gateway -----------------------------------
    #
    # Block initial recovery after a full cluster restart until N nodes are started:
    #
    #gateway.recover_after_nodes: 3
    #
    # For more information, consult the gateway module documentation.
    #
    # ---------------------------------- Various -----------------------------------
    #
    # Require explicit names when deleting indices:
    #
    #action.destructive_requires_name: true

这里说一下publish\_host，引用官方文档。

network.publish\_host  
The publish host is the single interface that the node advertises to other nodes in the cluster, so that those nodes can connect to it. Currently an Elasticsearch node may be bound to multiple addresses, but only publishes one. If not specified, this defaults to the “best” address from network.host, sorted by IPv4/IPv6 stack preference, then by reachability. If you set a network.host that results in multiple bind addresses yet rely on a specific address for node-to-node communication, you should explicitly set network.publish\_host.
