Elasticsearch配置账户密码

下载elasticsearch

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.5.0-linux-x86_64.tar.gz

解压

tar xf elasticsearch-7.5.0-linux-x86_64.tar.gz

创建elasticsearch用户

useradd -m -d /home/elk elk

mv elasticsearch-7.5.0 /home/elk/

chown -R elk:elk /home/elk/

然后修改vim /etc/sysctl.conf

vm.max_map_count = 262144

sysctl -p

切换用户然后编辑es配置文件

su – elk

cd /elasticsearch-7.5.0/config

vim 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: my-application

#

# ------------------------------------ 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: 本机的IP

#

# Set a custom port for HTTP:

#

http.port: 9200

#

# For more information, consult the network module documentation.

#

# --------------------------------- 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: ["本机IP"]

#discovery.seed_hosts: ["host1", "host2"]

#

# Bootstrap the cluster using an initial set of master-eligible nodes:

#

cluster.initial_master_nodes: ["node-1"]

#

# 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

#

#

# 配置跨域

http.cors.enabled: true

http.cors.allow-origin: "*"

http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

  #设置为false以禁用X-Pack机器学习功能

xpack.ml.enabled: false

#设置为true以开启X-Pack安全功能。

xpack.security.enabled: true

xpack.security.transport.ssl.enabled: true

启动一下看看有什么报错

../bin/elasticsearch -d

查看一下日志,没有报错则继续下一步

tail -200f ../logs/my-application.log

然后配置密码

../bin/elasticsearch-setup-passwords interactive

Y

然后反复输入想要设置的密码

最后在重启一下es，访问一下看看是否成功

Kibana就是在kibana.yml最下面加

elasticsearch.username: "elastic"

elasticsearch.password: "password"
