Ubuntu使用logwatch分析記錄檔，並透過Gmail寄出分析結果

Step1)安裝logwatch，查詢安裝的檔案與資料夾，建立分析暫存資料夾

#apt -y  install  logwatch

#dpkg -L logwatch

#mkdir /var/cache/logwatch

Step2)設定logwatch，將分析結果儲存到檔案/var/log/logwatch

#vi /usr/share/logwatch/default.conf/logwatch.conf

Output = file

Filename = /var/log/logwatch

Range = Today

Step3)使用logwatch分析記錄檔

#logwatch

定時執行logwatch

# vi /etc/crontab

58      23      *       *       *       root    /usr/sbin/logwatch

Step4)編輯logwatch.sh，新增標題與寄送給Gmail

/usr/home/jang/logwatch.sh

#!/bin/sh

awk 'NR==1{print "Subject: LogWatch 13\n\n"}1' /var/log/logwatch > /var/log/logwatch2

ssmtp zsg101101@gmail.com < /var/log/logwatch2

讓logwatch.sh具有執行權限

#chmod 700  logwatch.sh

定時執行logwatch.sh

# ee /etc/crontab

59      23      *       *       *       root    /root/logwatch.sh
