部署环境的系统是centos7.8
操作步骤
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.14.2-linux-x86_64.tar.gz
tar xf elasticsearch-7.14.2-linux-x86_64.tar.gz
mv elasticsearch-7.14.2 /data/elasticsearch
useradd elasticsearch -s /usr/sbin/nologin -U -M --system # 不允许使用root启动,需要创建用户
chown -R elasticsearch.elasticsearch /data/elasticsearch
sudo -u elasticsearch ./bin/elasticsearch -d # 直接启动
启动脚本
解压官方的7.14的rpm包抠出了init.d
脚本,修改了目录路径和参数,es7.x包默认带了java环境,不需要设置JAVA_HOME,会自动使用自带的。

chmod 700 /etc/init.d/elasticsearch
chkconfig --add elasticsearch
chkconfig elasticsearch on # 设置开机启动
systemctl daemon-reload
systemctl start elasticsearch # 启动服务
