一个简单的清理 Linux 日志的脚本

一台服务器运行一段时间后,系统就会产生各种各样的日志,而这些日志其实暴漏了系统的很多信息,这时候就需要定期清理使用痕迹


简单的清理脚本如下

#!/bin/bash
cat /dev/null > /var/log/boot.log
cat /dev/null > /var/log/btmp
cat /dev/null > /var/log/cron
cat /dev/null > /var/log/dmesg
cat /dev/null > /var/log/firewalld
cat /dev/null > /var/log/grubby
cat /dev/null > /var/log/lastlog
cat /dev/null > /var/log/mail.info
cat /dev/null > /var/log/maillog
cat /dev/null > /var/log/messages
cat /dev/null > /var/log/secure
cat /dev/null > /var/log/spooler
cat /dev/null > /var/log/syslog
cat /dev/null > /var/log/tallylog
cat /dev/null > /var/log/wpa_supplicant.log
cat /dev/null > /var/log/wtmp
cat /dev/null > /var/log/yum.log
cat /dev/null > /var/log/tuned/tuned.log
rm -f /var/log/*-20* > /dev/null 2>&1
if [ -d "/var/log/anaconda/" ] ; then
cat /dev/null > /var/log/anaconda/anaconda.log > /dev/null 2>&1
cat /dev/null > /var/log/anaconda/ifcfg.log > /dev/null 2>&1
cat /dev/null > /var/log/anaconda/journal.log > /dev/null 2>&1
cat /dev/null > /var/log/anaconda/packaging.log > /dev/null 2>&1
cat /dev/null > /var/log/anaconda/program.log > /dev/null 2>&1
cat /dev/null > /var/log/anaconda/storage.log > /dev/null 2>&1
cat /dev/null > /var/log/anaconda/syslog > /dev/null 2>&1
cat /dev/null > /var/log/anaconda/X.log > /dev/null 2>&1
fi
if [ -d "/var/log/audit/" ] ; then
rm -f /var/log/audit/audit.log* > /dev/null 2>&1
cat /dev/null > /var/log/audit/audit.log > /dev/null 2>&1
fi
cat /dev/null > ~/.bash_history
cat /dev/null > ~/.mysql_history
cat /dev/null > ~/.viminfo

最后别忘了额外运行一次 history -c 清理自己的命令列表
