下载地址如下版本号可以替换成自己想要的。 这里需要注意一点需要根据你服务器的内核来进行选择如下图所示我就应该选择aarch64版本的否则运行的时候会报错cannot execute binary file: Exec format error https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.9.3-linux-aarch64.tar.gz https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.9.3-linux-x86_64.tar.gz
解压安装包,并修改配置文件
解压
tar -zxvf elasticsearch-7.9.3-linux-aarch64.tar.gz
进入目录
cd elasticsearch-7.9.3
修改配置文件
vi config/elasticsearch.yml
有以下几点需要修改
放开node.name这个注释放开path.data、path.log注释并修改成你想要存放的位置修改network.host为0.0.0.0让其可以被IP访问修改cluster.initial_master_nodes 值为第一步配置的名字
下面是修改后的配置文件内容
# 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: /home/alllinks/elasticsearch-7.9.3/data
#
# Path to log files:
#
path.logs: /home/alllinks/elasticsearch-7.9.3/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: 9205
#
# 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: [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
添加用户并修改所有者
elasticsearch需要非root用户运行所以需要添加用户并修改elastielcsearch-7.9.3的所有者命令如下 useradd es chown es:es -R elastielcsearch-7.9.3
切换用户运行es
su es cd /elastielcsearch-7.9.3/bin ./elasticsearch -d
如何迁移旧版本的数据
如果有旧版本的数据的话可以将旧版本的数据直接cp到data目录下就好但是需要注意版本具体可以访问http://es服务器ip:9200。查看返回值minimum_wire_compatibility_version、minimum_index_compatibility_version
