Configuring the crontab
Several Koha programs need to be run periodically. These programs calculate fines, generate overdue notices, send out e-mails, or build Zebra indexes.
We use Linux's Cron utility to schedule the execution of these programs.
Editing the crontab
The cronjobs are set up under the koha user's crontab. To edit the crontab we run the command crontab with the –e option:
koha@koha@linux:~> crontab -e
To save and exit, we use the vi command wq:
:wq
Setting up environment variables
The first thing we need to do is to set Koha related environment variables in the crontab; without these none of the cronjobs will execute. Add these lines in the crontab, somewhere at the top:
PERL5LIB=/home/koha/kohaclone KOHA_CONF=/etc/koha-dev/etc/koha-conf.xml ...
