Fcron uses the cron facility of syslog to log all messages. Since LFS does not set up this facility in /etc/syslog.conf, it needs to be done prior to installing Fcron. This command will append the necessary line to the current /etc/syslog.conf:
cat >> /etc/syslog.conf << "EOF" # Begin fcron addition to /etc/syslog.conf cron.* -/var/log/cron.log # End fcron addition EOF
The configuration file has been modified, so reloading the sysklogd daemon will activate the changes.
For security reasons, an unprivileged user and group for Fcron should be created:
groupadd fcron && useradd -d /dev/null -c "Fcron User" -g fcron -s /bin/false fcron
Install Fcron by running the following commands:
./configure --without-sendmail --with-answer-all=no && make
Now, as the root user:
--without-sendmail: Fcron will use an installed MTA to email you the results of the fcron script. Omit the switch and use --with-sendmail=[/path/to/MTA] if you wish to utilize this feature.
--with-answer-all=no: After the files are installed, the make install script enters into a configuration routine. The first test will be whether to install a boot script in the /etc/rc.d/init.d directory with the appropriate symbolic links in run levels 2, 3, 4, and 5. The second is to stop any current fcron processes and start a new one. Since this is probably your first install and a boot script based upon the BLFS template is desired, answer 'n' to both tests.
There are no required changes in any of the config files. Configuration information can be found in the man page for fcron.conf.
fcron scripts are written using fcrontab. Refer to the fcrontab man page for proper parameters to address your situation.
Install the /etc/rc.d/init.d/fcron init script from the blfs-bootscripts-6.0 package.
If Linux-PAM is installed, two PAM configuration files are installed in /etc/pam.d. Alternatively if /etc/pam.d is not used, the installation will append two configuration sections to the existing /etc/pam.conf file. You should ensure the files match your preferences. Modify them as required to suit your needs.
