This page presents a script, which is used by this site, to extract, what pages have been accessed (from apache2 access log).

1. To view the main page of this work.
   This page explains how to run the script from crontab.


2. As said before, the data base for the script, is a root only access location and therefor this script can not be run from CGI. Instead the root runs it every hour and creates the HTML report,


3. To run crontab two files are required: the first one is a script, which is used to invoke the HTML report. This script, is placed in /etc/init.d, in my debian machine. The script is simple and is shown with its documentation here:
   #! /bin/sh
   
   #0 * * * * /etc/init.d/aac_day_rep.unx >>/dev/null 2>&1
   #* * * * * command to be executed
   #I I I I I
   #I I I I I
   #I I I I I
   #I I I I I..... day of week (0 - 6) (0 is Sunday, or use names)
   #I I I ........... month (1 - 12)
   #I I I............... day of month (1 - 31)
   #I I.................... hour (0 - 23)
   #.......................... min (0 - 59)
   
   #yearly (or @annually) Run once a year, midnight, Jan. 1st 0 0 1 1 *
   #monthly Run once a month, midnight, first of month 0 0 1 * *
   #weekly Run once a week, midnight on Sunday 0 0 * * 0
   #daily Run once a day, midnight 0 0 * * *
   #hourly Run once an hour, beginning of hour 0 * * * *
   #reboot Run at startup
   
   
   1. #An example from my debian server
      
   3. #Look for and purge old sessions twice hourly (at 9 and 39).
      
   5. 09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -ignore_readdir_race -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir fuser -s {} 2>/dev/null \; -delete
      
   
   if [ -e "/var/log/apache2/access.log.1" ] ; then
     cat /var/log/apache2/access.log.1 /var/log/apache2/access.log > /var/log/apache2/access_tmp.log
     perl /home/pini/Home_2/my_web/www_access_day.pl /var/log/apache2/access_tmp.log
     rm -f /var/log/apache2/access_tmp.log
   else
     perl /home/pini/Home_2/my_web/www_access_day.pl /var/log/apache2/access.log
   fi
   


4. To run a backup, not as root (only user kuku has no password scp access), twice a day:
   
   
   1. su - pini -c "date +%y%m%d_%H%M%S > ~/Home_2/WorkAtHome/pini_work_hour_bak.txt"
   2. su - pini -c "scp -r /home/pini/Home_2/WorkAtHome/BroadCom pini@192.168.0.179:~/Home_2/WorkAtHome"
   
   
   And add this line to the crontab start file.
   
   0 10,23 * * * /etc/init.d/work_hour_bak.unx >>/dev/null 2>&1
   


5. To operate the script a crontab file has to be created. This file has two entries. One for this script and another for time update. The latter is described using ntpdate-debian command.
   0 * * * * /etc/init.d/aac_day_rep.unx >>/dev/null 2>&1
   0 0 * * * /etc/init.d/init_ntpdate.unx >>/dev/null 2>&1
   To enter this entries in crontab, I first erased the former entry by:
   crontab -r
   and then put the new one by:
   crontab CRfile.txt
