    ## WARNING: DO NOT EDIT THIS FILE. If you want to override the
    ## JVM options in this file, or set any additional options, you
    ## should create one or more files in the jvm.options.d
    ## directory containing your adjustments.

    ## IMPORTANT: JVM heap size
    ################################################################
    ##
    ## The heap size is automatically configured by Elasticsearch
    ## based on the available memory in your system and the roles
    ## each node is configured to fulfill. If specifying heap is
    ## required, it should be done through a file in jvm.options.d,
    ## and the min and max should be set to the same value. For
    ## example, to set the heap to 4 GB, create a new file in the
    ## jvm.options.d directory containing these lines:
    
    -Xms31g
    -Xmx31g
    
    ## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html

# 重启 #

## 关掉集群 分片 自动分配设置 ##

PUT /_cluster/settings
    {
      "transient": {
        "cluster.routing.allocation.enable": "none"
      }
    }

## 修改配置重启所有节点 ##

docker-compose stop
    docker-compose up -d --build

等最后一个节点起来后，进入容器执行

./bin/elasticsearch-setup-passwords interactive

设置对应账号名的密码即可。
