- 配置
es集群名称（默认是被正文的，并且默认有一个集群名）
# ---------------------------------- Cluster -----------------------------------## Use a descriptive name for your cluster:#cluster.name: my-application#- 配置以后
es节点名称（默认是被正文的，并且默认有一个节点名）
# ------------------------------------ Node ------------------------------------## Use a descriptive name for the node:#node.name: node-1## Add custom attributes to the node:##node.attr.rack: r1#- 配置
存储数据目录门路（用逗号分隔多个地位）和日志文件门路
# ----------------------------------- Paths ------------------------------------## Path to directory where to store the data (separate multiple locations by comma):#path.data: /usr/local/elasticsearch-7.6.2/data## Path to log files:#path.logs: /usr/local/elasticsearch-7.6.2/logs#- 绑定地址为特定 IP 地址（设置
0.0.0.0能够让任何人拜访到你的 es），设置一个 http 申请端口（默认 9200）
# ---------------------------------- Network -----------------------------------## Set the bind address to a specific IP (IPv4 or IPv6):#network.host: 0.0.0.0## Set a custom port for HTTP:#http.port: 9200## For more information, consult the network module documentation.#- 集群启动时，设置
master节点列表（用逗号分隔，目前单机所以只配置了一个）
# --------------------------------- 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: ["host1", "host2"]## Bootstrap the cluster using an initial set of master-eligible nodes:#cluster.initial_master_nodes: ["node-1"]#jvm.options 配置
Xms、Xmx设置为统一即可
# Xms represents the initial size of total heap space# Xmx represents the maximum size of total heap space-Xms256m-Xmx256mvm.max_map_count 配置
[root@localhost config]# vi /etc/sysctl.confvm.max_map_count=655360[root@localhost logs]# sysctl -pvm.max_map_count = 655360创立用户并赋予es装置目录权限
这是ES的一种安全措施，不让用root用户
创立一个 esroot 用户并设置初始密码

jdk版本谬误
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
这是因为jdk版本太低造成的，jdk版本须要在9.0以上，因而须要重新安装jdk
