How i must write "openrc-run" script for launch boot service?

inukaze · 2018-08-30 22:53:03

Hi there. some days ago, i post this thread -> https://dev1galaxy.org/viewtopic.php?id=2306
and well yesterday i upgrade the software on my Devuan Jessie.

Right now, the Service don't start at boot. the first was the "/sbin/runscript" don't exist anymore
the second is i modify the first line on the script, there are the command to generate the script :

echo '#!/sbin/openrc-run

description="Start/Stop the no-ip daemon"

depend()
{
        after *
        keyword notimeout
}

start()
{
        ebegin "Starting NoIP"

        /usr/bin/noip2

        eend $? "Failed to start NoIP"
}

stop()
{
        ebegin "Stopping NoIP"

        killall -TERM /usr/bin/noip2

        eend $? $"Failed to stop NoIP"
}' | sudo tee /etc/init.d/noip2 ; sudo chmod a+rx /etc/init.d/noip2

and right now in the /var/log/boot :

Thu Aug 30 18:31:38 2018:  ^[[1m^[[31m*^[[m noip2: not enough arguments^[[K
Thu Aug 30 18:31:38 2018:  ^[[1m^[[31m*^[[m ERROR: noip2 failed to start^[[K

when i reach my desktop environment and i try to run it directly from cli :

sudo service noip2 start
 * WARNING: noip2 has already been started

ps -A | grep noip

the "noip2" is not running. with the old version of runscript works perfectly. but right now i don't have idea how to make it work.

I am not sure exactly what your problem is, but here is how OpenRC init process are run.

OpenRC init scripts need to be in /etc/init.d/, this is what "runs".

OpenRC runlevels are defined in /etc/runlevels/, you need a symlink here under the desired runlevel pointing to the script in /etc/init.d/ so the script gets run.

Once you have the script in /etc/init.d/, you enter "rc-update add <service> <runlevel>" where <service> is your script name in /etc/init.d/ and <runlevel> is your desired runlevel under /etc/runlevel.

From your post, it seems you need some sort of "noip" startup script in /etc/init.d, and then perform the rc-update add noip default (for default runlevel, or whatever runlevel).

The problem is the noip2 don't start at boot anymore, after the last upgrade, when the runscript dont exist anymore in /sbin/runinit, instead follow gentoo wiki, i should use openrc-run for the shebang in the first line.

ralph.ronnquist · 2018-08-31 06:53:55

echo '#!/sbin/openrc-run

is an unusual first line for a script. Or was it a mistake when copying to here? Otherwise you should remove the first 6 characters, so that the very first character is the "#" character. Or equally, make it so to say:

#!/sbin/openrc-run

inukaze · 2018-08-31 09:37:18

That are a command to generate the script from cli. its not directly the script. the first line inside the script is :

#!/sbin/openrc-run

if you read the lines, you see at the end, the command :

sudo tee /etc/init.d/noip2 ; sudo chmod a+rx /etc/init.d/noip2

For generate the file and make executable for all users.

ralph.ronnquist · 2018-08-31 10:49:41

ah. of course.

If you've done the set up as @dxrobertson mentioned, maybe the problem is that the noip2 daemon needs some configuration that is missing? E.g., should it have "-i IPaddress" on the command line? Though, I must admit I know less about noip2 than is written at https://github.com/jamesstout/no-ip/blo … ADME.FIRST.

dxrobertson · 2018-08-31 23:52:02

Confused.

Your original post states "How i must write "openrc-run" script for launch boot service?". Assuming OpenRC is the init process.

But you used the command "sudo service noip2 start", which is a sysvinit command.

OpenRC or sysvinit?

Please post contents of /etc/init.d/rcS. OpenRC should be:

#!/bin/sh
# Wrapper of OpenRC called from inittab

set -e
exec /sbin/openrc sysinit

It might help to also post /etc/inittab, should have:

# Boot-time system configuration/initialization script.
# This is run first except when booting in emergency (-b) mode.
si::sysinit:/etc/init.d/rcS

inukaze · 2018-09-01 09:57:54

$ cat /etc/init.d/rcS
#!/bin/sh
# Wrapper of OpenRC called from inittab

set -e
exec /sbin/openrc sysinit

$ cat /etc/inittab
# Boot-time system configuration/initialization script.
# This is run first except when booting in emergency (-b) mode.
si::sysinit:/etc/init.d/rcS

dxrobertson · 2018-09-01 12:16:09

OK, you are using OpenRC.

I am guessing that noip2 is an init script, and that it is supposed to run the actual program noip? Assuming so...

There should be a noip2 script in /etc/init.d, does it exist? If so, is it formatted correctly, similar to the other scripts in /etc/init.d? You can post the contents if you like.

OpenRC commands you can use, you can post the output here if you like:

display all init scripts and what runlevel they run under:

rc-update show

noip2 should display

display what is setup to run by runlevel

rc-status -a

noip2 should display as started

manually run noip2

rc-service noip2 start

set noip2 to run automatically under runlevel default

rc-update add noip2 default

$ sudo rc-service noip2 start ; ps -A | grep noip
 5100 ?        00:00:00 noip2

Well let me restart to test the changes. because with manual start using rc-service, now run
The Process don't run automatically at boot. i don't understand why.
but right now, i not got errors with noip2 during boot process.

OpenRC logging may help with init process problems. You can enable logging in /etc/rc.conf. The log file will be /var/log/rc.log".

To enable OpenRC logging, edit /etc/rc.conf:

rc_logger="YES" 
rc_verbose=yes

This morning i purge some packages of sysvinit installed on my distro, anothers i dont use like upstart, plymouth, mdadm, cryptset or something similar.

Well i copy /etc/init.d/mpd to /etc/init.d/noip2 and i start the modifications. but one part i can't understand fine :

ok the main modification was things like :

MPDCONF=/etc/mpd.conf by NOIP2CONF=/usr/etc/no-ip2.conf
DAEMON=/usr/bin/noip2

and well the unique thing i don't understand what do is the line :
PIDFILE=$(sed -n 's/^[[:space:]]*pid_file[[:space:]]*"\?$[^"]*$\"\?/\1/p' $MPDCONF)

because with mpd :

echo $PIDFILE
/run/mpd/pid

if i try with my modification
PIDFILE=$(sed -n 's/^[[:space:]]*pid_file[[:space:]]*"\?$[^"]*$\"\?/\1/p' $NOIP2CONF)

echo $PIDFILE

nothing happened.

Well i try to make accord to the system. but i change at the final i just let the file with the follow content :

#!/bin/sh

during boot the another process show

i try to make it equal with my noip2 script, but i can't understand the PIDFILE and what do the sed in that variable.

I cant help much with the init script writing. Hopefully someone else can help.

I think the mpd script is using the sed command to generate a pid file name. I dont think you need to do that. Some scripts just use a hard-coded pid file name.

If you look at some of the other init scripts such as rsyslog or cups; they use start-stop-daemon to run and the pid file is used as a parm.

Sorry I cant be of much help here.
