编写开机启动脚本

#!/bin/sh
#chkconfig: 2345 80 05
#description: elasticsearch

#jdk相关路径
export JAVA_HOME=/var/local/java/jdk1.8.0_241
export JAVA_BIN=/var/local/java/jdk1.8.0_241/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

    #es的启动账号名

    cd /var/local/elasticsearch-6.2.4/
    ./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 /var/local/elasticsearch-6.2.4/
    ./bin/elasticsearch -d

    echo "start|stop|restart"
    ;;
esac

exit $?

脚本中的各种路径需要根据自己服务器修改。

为启动脚本增加执行权限：

chmod +x /etc/init.d/elastisearch

配置开机启动es：

chkconfig --add elastisearch
1
重启机器：

reboot
1
检查ES是否启动：

jps
