Elasticsearch启动脚本

编写脚本

• 说明：需指定JDK环境，要不然会默认使用es自带的JDK，自带的版本太新，去除了GC。

vim /etc/init.d/elasticsearch
#!/bin/sh
#chkconfig: 2345 80 05
 
export JAVA_HOME=/data/app/jdk-13.0.1
export PATH=$JAVA_HOME/bin:$PATH
export ES_HOME=/data/elasticsearch/
export PATH=$ES_HOME/bin:$PATH
 
 
case $1 in
    start)
        cd $ES_HOME
        ./bin/elasticsearch -d -p pid
        exit
!
        echo "elasticsearch is started"
        ;;
    stop)
        pid=`ps -ef | grep "Elasticsearch" |grep -v "grep" | awk '{print $2}'`
        kill -15 $pid
        echo "elasticsearch is stopped"
        ;;
    restart)
        pid=`ps -ef | grep "Elasticsearch" |grep -v "grep" | awk '{print $2}'`
        kill -15 $pid
        echo "elasticsearch is stopped"
        sleep 1
        cd $ES_HOME
        ./bin/elasticsearch -d -p pid
        exit
!
        echo "elasticsearch is started"
        ;;
    *)
        echo "start|stop|restart"
        ;;
esac
exit 0

添加到开机启动任务

chmod +x /etc/init.d/elasticsearch 
chkconfig --add elasticsearch 
service elasticsearch restart
