ELK安装：2.1、之ES安装

1、ES部署

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.11.1-linux-x86_64.tar.gz

1.1、单机运行（一）

ES解压后不用做配置，使用默认配置即可，运行监听IP是127.0.0.1

后台运行 # ./elasticsearch -d

1.2、单机运行（二）

配置监听，修改config目录下的elasticsearch.yml文件，修改前先备份：

# network.host: 192.168.1.200

#node.name: node-1

#cluster.initial_master_nodes: [“node-1”]

1.3、集群配置

# ======================== 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-es-app

node.master: true

node.data: 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: /home/elk/elasticsearch-7.6.0/data

# Path to log files:

path.logs: /home/elk/elasticsearch-7.6.0/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

# 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: ["192.168.1.200:9300", "192.168.1.201:9300"]

# 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
