linux auto shell

ELK.sh

建立一個sh檔案，加入以下指令:
sh /home/es3/Downloads/elasticsearch-5.6.6/bin/elasticsearch &
sh /home/es3/Downloads/kibana-5.6.6-linux-x86_64/bin/kibana

cd /home/logstash/Downloads/logstash-5.6.6/bin
sh logstash -f /home/logstash/Downloads/logstash-5.6.6/bin/flow.conf

logstash server:
#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
systemctl stop ntopng &
systemctl stop firewalld &
systemctl stop nprobe &
sleep 5
nprobe /c --zmq "tcp://*:2055" -i none -n none --collector-port 5556 &
ntopng /c -i tcp://127.0.0.1:2055 -F "logstash;163.19.163.230;tcp;5510" --local-networks "163.19.0.0/16" &
cd /home/logstash/Downloads/logstash-5.6.6/bin
sh logstash -f /home/logstash/Downloads/logstash-5.6.6/bin/flow.conf


crontab -e 
加入以下指令:
@reboot su logstash -c "sh /home/logstash/Downloads/test.sh"
