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!
