[SOLVED] Can't get rc.local to work

[Serophis]

Hi,

I'm trying to get rc-local.service working on my Fedora 17 64-bit system but it keeps failing. I've made it executable and here is the contents:

#! /bin/sh
chmod 755 /etc/rc.d/rc.local
ln -s /etc/rc.d/rc.local /etc/
# Use deadline scheduler for SSD-disk
echo deadline > /sys/block/sdb/queue/scheduler
echo 1 > /sys/block/sdb/queue/iosched/fifo_batch
# Write-back caching
hdparm -W1 /dev/sdb

systemctl status rc-local.service shows:

rc-local.service - /etc/rc.d/rc.local Compatibility
Loaded: loaded (/usr/lib/systemd/system/rc-local.service; static)
Active: failed (Result: exit-code) since Tue, 31 Jul 2012 07:39:16 +0200; 5min ago
Process: 1818 ExecStart=/etc/rc.d/rc.local start (code=exited, status=127)
CGroup: name=systemd:/system/rc-local.service

I have no idea what I'm doing wrong, and google isn't helping much. I only created rc.local to optimize the OS for SSD.

The way I got my rc.local to work was to execute the following as root:

ln -s /lib/systemd/system/rc-local.service /etc/systemd/system/multi-user.target.wants/rc-local.service

Then I wrote the /etc/rc.d/rc.local file (the first line being #!/bin/sh like yours) and make that file executable:

chmod 755 /etc/rc.d/rc.local

I then enabled it with:

systemctl enable rc-local.service

so that it ran on each boot up. In my case I used the rc.local file to create some links in /dev and make a /dev/dsp and it all worked. Now, when I ask systemctl the status of rc-local.service I get:

rc-local.service - /etc/rc.d/rc.local Compatibility
Loaded: loaded (/usr/lib/systemd/system/rc-local.service; enabled)
Active: active (exited) since Thu, 02 Aug 2012 08:47:08 +1000; 1h 17min ago
Process: 721 ExecStart=/etc/rc.d/rc.local start (code=exited, status=0/SUCCESS)
CGroup: name=systemd:/system/rc-local.service

and everything works as intended from my point of view.

From your first quote it looks as if you are trying to make the rc.local file executable from within the rc.local file itself. I can't see how this can work. If the rc.local file is not executable when the operating system first sees it (without looking into its contents), it ignores it. Rather, the rc.local file should be made executable by your chmod command before the operating system tries to execute it. I would remove the chmod and ln commands from your rc.local file, keep the rest of it, and try the above approach which I have outlined to see how that goes, bearing in mind that the commands in your rc.local file have to be workable as well on your system for it all to work. ben.

Following your suggestions didn't work at first. Then I examined the commands I had put into rc.local and noticed that 'hdparm' didn't work. A quick 'yum install hdparm' fixed that, following with a 'systemctl restart rc-local.service' got rc.local working fine.

I really am a noob when it comes to Linux, lol!

Thanks for the help.
