一、创建脚本文件
在 /etc/init.d 目录下，创建脚本文件 elasticsearch
# cd /etc/init.d/ # vim elasticsearch
将以下内容写入文件中（其中JDK安装路径、elasticsearch安装路径及用于启动的elasticsearch的用户根据实际情况进行修改）
#!/bin/sh #chkconfig: 2345 80 05 #description: elasticsearch export JAVA_HOME=/usr/local/java/jdk1.8.0_171 export JAVA_BIN=/usr/local/java/jdk1.8.0_171/bin export PATH=$PATH:$JAVA_HOME/bin export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME JAVA_BIN PATH CLASSPATH case "$1" in start) su - es<<! cd /usr/local/elasticsearch-6.8.1 ./bin/elasticsearch -d ! echo "elasticsearch startup" ;; stop) es_pid=`ps aux|grep elasticsearch | grep -v 'grep elasticsearch' | awk '{print $2}'` kill -9 $es_pid echo "elasticsearch stopped" ;; restart) es_pid=`ps aux|grep elasticsearch | grep -v 'grep elasticsearch' | awk '{print $2}'` kill -9 $es_pid echo "elasticsearch stopped" su - es<<! cd /usr/local/elasticsearch-6.8.1 ./bin/elasticsearch -d ! echo "elasticsearch startup" ;; *) echo "start|stop|restart" ;; esac exit $?
保存退出
二、设置开机自启
在 /etc/init.d 目录下赋予新创建的elasticsearch文件执行权限
# chmod +x elasticsearch
添加到开机启动任务
# chkconfig --add elasticsearch
重启机器，检测elasticsearch是否自启
# ps -ef|grep elasticsearch
elasticsearch进程已经起来
检测elasticsearch服务是否正常
# curl http://192.168.56.13:9200
服务正常，至此Linux下设置Elasticsearch开机自启完成！
