[root@localhost elasticsearch-7.17.18]# 三、修改配置文件
conf/elasticsearch.yml
注意配置修改：
path.data：数据目录
path.logs：日志文件目录
network.host：网络地址
http.port：通信端口
固定写法配置：
xpack.ml.enabled: false
ingest.geoip.downloader.enabled: false
discovery.type: single-node完整配置：
# ======================== 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-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: /usr/local/elasticsearch/data
#
# Path to log files:
#
path.logs: /usr/local/elasticsearch/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 -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 0.0.0.0
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 19250
#
# 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", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
#
# ---------------------------------- Security ----------------------------------
#
# *** WARNING ***
#
# Elasticsearch security features are not enabled by default.
# These features are free, but require configuration changes to enable them.
# This means that users don't have to provide credentials and can get full access
# to the cluster. Network connections are also not encrypted.
#
# To protect your data, we strongly encourage you to enable the Elasticsearch security features.
# Refer to the following documentation for instructions.
#
# https://www.elastic.co/guide/en/elasticsearch/reference/7.16/configuring-stack-security.html
xpack.ml.enabled: false
ingest.geoip.downloader.enabled: false
discovery.type: single-node四、创建elasticsearch用户
elasticsearch不支持使用root用户启动，故而需要新增一个用户启动
# 创建用户组
sudo groupadd elasticsearch
# 创建用户并加入用户组
sudo useradd -g elasticsearch elasticsearch
# 配置用户目录权限
sudo chown -R elasticsearch:elasticsearch /path/to/elasticsearch五、注册service服务
创建elasticsearch.service
注意修改elasticsearch目录：/opt/service/elasticsearch/bin/elasticsearch
将编辑好的elasticsearch.service上传至/etc/systemd/system目录下
[Unit]
Description=elasticsearch
After=network.target
[Service]
Type=forking
User=elasticsearch
Group=elasticsearch
ExecStart=/opt/service/elasticsearch/bin/elasticsearch -d
PrivateTmp=true
LimitNOFILE=65535
LimitNPROC=4096
LimitMEMLOCK=infinity
TimeoutStopSec=0
KillSignal=SIGTERM
SendSIGKILL=no
SuccessExitStatus=143
[Install]
WantedBy=multi-user.target注册并启动服务
# 加载systemd配置
sudo systemctl daemon-reload
# 启动服务
sudo systemctl start elasticsearch
# 查看服务状态
sudo systemctl status elasticsearch
# 停止服务
sudo systemctl stop elasticsearch
# 重启服务
sudo systemctl restart elasticsearch六、验证服务
浏览器访问：http://ip:19250
输出以下信息证明服务正常
