[gentoo-user] daemon start up problem

[gentoo-user] daemon start up problem

[K. Mike Bradley]

Hello,
I am running latest Gentoo.
I want to start my app as a daemon.
This app has a script to do so.

webservice.sh

I copied this file to /etc/init.d/

I made a link:

/etc/runlevels/default/webctrl ---> /etc/init.d/webservice.sh

If I start manually it's ok:

/etc/init.d/webservice.sh start

But when I re-boot I get:


*WARNING:   /etc/init.d/webctrl missing ... Skipping            [ok] 

 

If I run:

nano /etc/runlevels/default/webctrl

I get the webservice.sh that the link points to.

Please help.

I would imagine that the init system of Gentoo expects the links in
/etc/runlevels/... to have the same name as the script they link to.

So to get proper behaviour: 
ln -sf /etc/init.d/webservice.sh /etc/runlevels/default/webservice.sh
(or "rc-update add webservice.sh default")

Then remove /etc/runlevels/default/webctrl
 
That should fix it...

I tried rc-update originally but got an error message which is why I
manually made the link.

I removed the webctrl link and rc-update as you detailed and it worked this
time, but ...

When I boot I get:

Usage: /sbin/rc { start | stop}

And the service is not running.

Could this be a script error in the webservice.sh provided by the app
vendor?

Thanks for all your help.

This kind of side steps the issue but if you'd rather just have it
working and not have to learn all about runlevels etc.... you could
just put it in /etc/conf.d/local.start.

That gets called from /etc/init.d/local  as the last thing started.

If you do use that method remember to put a `&' after the script call
or you might hang up the boot process waiting for a return.

You haven't read the documentation for Gentoo rc-scripts.  This script 
was likely developed for a different distribution, for example Debian.  
Gentoo rc-scripts require, in addition to start() and stop(), a 
checkconfig() function that lets the rc services know what services this 
one requires.  You'll need to either manually figure out the 
dependencies and add a checkconfig(), or simply add 'webservice.sh start 
&' to /etc/conf.d/local.start and 'webservice.sh stop &' to 
/etc/conf.d/local.stop as another poster recommended.

To learn more about rc-scripts and their required functions, run 
'/etc/init.d/webservice.sh help'  (or any service in /etc/init.d).

Also, the script as provided seems to expect to be run from a certain 
CWD with your JRE relative to there.  This is unlikely to work on 
Gentoo, especially given Gentoo's use of java-config to support 
different JREs.
