elasticsearch-head开机自启动

1. cd /etc/init.d 进入目录
2. 创建文件eshead,把下面内容粘贴进去,修改对应的环境变量java/node等

#!/bin/bash
#
#chkconfig: 345 63 37
#description: elasticsearch-head-master
#processname: elasticsearch-head-master

export NODE_HOME=/usr/local/node-v15.5.0-linux-x64
export JAVA_HOME=/usr/local/jdk1.8.0_271
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export NODE_PATH=$NODE_HOME/lib/node_modules
export PATH=$PWD/bin:/usr/local/openresty/nginx/sbin:$JAVA_HOME/bin:$NODE_HOME/bin:$PATH

ESHEAD_HOME=/usr/local/elasticsearch-head-master/

case $1 in
  start)
    cd $ESHEAD_HOME
        nohup grunt server 2>&1 &
    echo "eshead is started"
    ;;
  stop)
    pid=`lsof -t -i:9100`
        kill -9 $pid
    echo "eshead is stop"
    ;;
  restart)
    pid=`lsof -t -i:9100`
        kill -9 $pid
        echo "eshead is stopped"
    sleep 1
        cd $ESHEAD_HOME
        nohup grunt server 2>&1 &
    echo "eshead is started"
    ;;

    ;;
esac
