本文以 elasticsearch-7.8.1为例。

1.下载ES并解压

cd /root/install
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.8.1-linux-x86_64.tar.gz
tar -zxvf elasticsearch-7.8.1-linux-x86_64.tar.gz

2.新建elasticsearch用户

使用root用户登录，新建elasticsearch用户。

useradd elasticsearch
passwd elasticsearch
chown -R elasticsearch:elasticsearch /root/install/elasticsearch-7.8.1

3.修改ES配置文件

vi /opt/elasticsearch-7.8.1/config/elasticsearch.yml

node.name: node-1    #节点名称
path.data: /opt/data/es/data    #数据存储路径

4.启动ES服务

# 切换用户 
su - elasticsearch
# 启动ES
sh /root/install/elasticsearch-7.8.1/bin/elasticsearch

5.设置开机启动

vi /etc/init.d/elasticsearch

#!/bin/bash
#
#chkconfig: 345 63 37
#description: elasticsearch
#processname: elasticsearch-7.8.1ES_HOME=/root/install/elasticsearch-7.8.1case $1 instart)su - elasticsearch -c "$ES_HOME/bin/elasticsearch -d -p pid"echo "elasticsearch is started";;stop)pid=`cat $ES_HOME/pid`kill -9 $pidecho "elasticsearch is stopped";;restart)pid=`cat $ES_HOME/pid`kill -9 $pidecho "elasticsearch is stopped"sleep 1su - es -c "$ES_HOME/bin/elasticsearch -d -p pid"echo "elasticsearch is started";;*)echo "start|stop|restart";;  
esac
exit 0

chmod 777 /etc/init.d/elasticsearch
chkconfig --add elasticsearch #设置开机启动
chkconfig --del elasticsearch #删除开机启动chkconfig elasticsearch on    #打开开机启动
chkconfig elasticsearch off   #关闭开机启动
