Freebsd – How to run simple command on startup on FreeBSD

freebsdstartup

I need to run a command at startup on my machine using FreeBSD:

cd /home/portal
mv portal.sqlite corrupt_portal.sqlite

This is clearly not a daemon or a service, just a one time command at every boot.

I tried to put a .sh file inside /usr/local/etc/rc.d/ with #!/bin/bash and it doesn't do anything, I also tried to simply write touch testfile
If I run both versions manually they work with no problem.

What am I missing here?

The rc(8) script is responsible for running the automatic boot process, and the example section of the manual gives a simple template for the /etc/rc.d/ directory. Read the rc.subr(8) manual page for further guidance on writing startup scripts.

However, one of the final stages of the automatic boot process is to read a script file called /etc/rc.local (if it exists). This file requires no special formatting or keywords, or the execute bit set.

From the rc(8) manual page:

Typically, the /usr/local/etc/rc.d/ mechanism is used instead of rc.local these days but if you want to use rc.local, it is still supported.

The problem is simple, you are using OpenSuse 12.1 which uses systemd instead of your classic System V boot system.

To install a new service place create following file in /etc/systemd/system/myprogname.service

[Unit]
Description=My progname service file

[Service]
ExecStart=/home/bits/MyProgram

[Install]
WantedBy=multi-user.target

Aftwards run systemctl daemon-reload and systemctl start myprogname.service

If you want to automatically restart MyProgname you have to add

Restart=restart-always

to the service section.

Debian – Run script on start up after everything else

Check if the init script you want to delay have a comment block like this:

### BEGIN INIT INFO
# Provides:          scriptname
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Start daemon at boot time
# Description:       Enable service provided by daemon.
### END INIT INFO

This block, as stated in Debian's LSBInitScripts wiki tells the init subsystem that some other facilities should be Required to be started before your nagios script runs.

Then, all you need to do is to point out why your nagios init script needs to be restarted, it's because of network not up yet? It's because webserver still starting? Or, nfs not yet in sync?

It's up to you to find out why you need to re-start nagios every time, but this approach is the most elegant solution to your case.
