Ubuntu cron log opening and viewing implementation steps

Ubuntu cron log on and see the implementation steps

ubuntu does not turn on cron logging by default

1. Modify rsyslog

vim /etc/rsyslog.d/50-default.conf 

cron.* /var/log/cron.log 

# Remove the comment before cron

2. Restart rsyslog

service rsyslog restart 

3. Check the crontab log

tail /var/log/cron.log

By default, cron will send an email to the running result of the task, such as error message, to the mailbox of system users, but the specific output information of script running will not appear in log. Therefore, we can specify the output log path of each task under 1:

0 2 * * * db_backup task; >> /var/log/db_backup.log 2>&1

Then we can go to the appropriate log file to see the script output.
