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, we need to create an unprivileged user and group for fcron:
groupadd fcron && useradd -d /dev/null -g fcron -s /bin/false fcron
Install Fcron by running the following commands:
./configure --without-sendmail --with-answer-all=no && make && make install
--without-sendmail: Fcron will use an iinstalled MTA to email you the results of the fcron script. If you wish to utilize this feature, change the switch to --with-sendmail=[path to your MTA] .
--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 we want a boot script based upon the BLFS template, we answer 'n' to both tests.
--with-dsssl-dir=/usr/share/sgml/docbook/dsssl-stylesheets-1.78 : This switch can be added if you have installed OpenJade and dsssl-stylesheets to generate the documentation from the DocBook source files.
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-5.1 package.
The Fcron package contains fcron, fcrontab, fcronsighup and fcrondyn.
