Hi All Ubuntu Server Experts
I need help in cracking this crontab problem. So, I made a change in /etc/crontab to run a system script for database backup purpose. The crontab does not seems to run my script and I cannot view the crontab status anywhere. I even uses root account for my ubuntu server.
So, I made a simple echo script in crontab and it worked ok. What is wrong with my script?
Here are some clues: This is my /etc/crontab file
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/DataBank/Bac$
# m h dom mon dow user command
17 * * * * root cd / && run-parts --report /etc/cron.hourly
25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --repo$
47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --repo$
52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --repo$
* * * * * root sh /DataBank/Backup/Scripts/backupdb.sh --> this one does not run
* * * * * root echo "Running Sample Crontab by the minute: $(date)" >>$ --> this one works
and This is my backup scripts located at /DataBank/Backup/Scripts/backupdb.sh:
echo "Backing up database... $(date)" >> backuplog.txt
DBFILENAME=db`date "+%Y%m%d-%H.%M.%S"`.sql
/Tech/MySQL/Server/bin/mysqldump -c ITWorksEEDB > ../DB/$DBFILENAME --user=root$
echo "Backup done: $DBFILENAME $(date)" >> backuplog.txt
and My backup file permissions: (all 777)
root@MoMa:/DataBank/Backup/Scripts# ls -al
total 11
drwxrwxrwx 1 root root 4096 Jan 4 13:03 .
drwxrwxrwx 1 root root 4096 Oct 8 21:13 ..
-rwxrwxrwx 1 root root 257 Jan 4 13:05 backupdb.sh
-rwxrwxrwx 1 root root 257 Jan 4 13:32 backupdb.sh.bak
-rwxrwxrwx 1 root root 236 Jan 4 13:05 backuplog.txt
-rwxrwxrwx 1 root root 79 Jun 25 2013 shutAll.sh
-rwxrwxrwx 1 root root 55 Aug 23 2012 shutSPC.sh
When I run the backupdb.sh manually using "sh backupdb.sh", it works perfectly. When I use this command: ./backupdb.sh (without sh), this error message occurs:
root@MoMa:/DataBank/Backup/Scripts# ./backupdb.sh
-bash: ./backupdb.sh: Permission denied --> My backupdb.sh file is supposed to be 777
Can anyone help me how to make the script run in crontab or at least to see the status returned by crontab when running the script?
Thank you Rendra
crontab -efrom the specific user account. 2) cron has no environment, i.e. just because a command in on yourPATHdoes not mean that it will be on cron's.
