kill $(ps -A -ostat,ppid | awk '/[zZ]/ && !a[$2]++ {print $2}') tcpdump 'arp' -e -i eth0 -n -p -t |grep is-ateth0对应要换成你的显步名称
tcpdump -n -vv tcp port $1 -i em1em1为对应的网卡名称。
netstat -nat |awk '{print $6}'|sort|uniq -c|sort -nr tail -F /var/log/tomcat8/catalina.out |grep -E 'Exception|at' |grep -v WARN这里tomcat8要对应成你的相应版本
sudo find /var/lib/tomcat8/logs/ -mtime +5 -exec rm {} \; 以下存成脚本，

使用goaccess软件，可能用apt install goaccess或yum install goaccess安装。
sudo goaccess /var/log/nginx/access.log --log-format='%h %^[%d:%t %^] "%r" %s %b "%R" "%u" "-" "%v"' --date-format='%d/%b/%Y' --time-format='%H:%M:%S'
nginx会频繁修改，改之前最好备份一下：
