Deleted /sbin/init ... Recovered From Live CD, Still Will Not Boot?

hello everyone,
I created a script file (info.sh) in linux centos 6.
location of file is '/etc/init.d/info.sh'
content of file is:

#!/bin/sh
#To get the MAC address
ifconfig | grep HWaddr
#To get the HDD serial no.
hdparm -I /dev/sd? | grep 'Serial\ Number'
#To get the HDD size
hdparm -I /dev/sda |grep "device size"

gave the permission by: chmod 777 /etc/init.d/info.sh
but when i run this file by: /etc/init.d/info.sh
it gives an error like...
-bash: /etc/init.d/info: cannot execute binary file

what should i do?? Actually i have to run this file during boot up..

thanks in advance..

hi guys,

i know what initialization systems are, and pretty much what they do.
lately everybody has been giving out about various distros changing to systemd...

firstly have i got this right?

init is pretty much retired and used on many older distros

debian used init then switched to upstart and now uses systemd...though you can keep using upstart but its difficult to get right.

slackware uses a hybrid type sysv with bsd like scripting...

centos 7 is using systemd by default

so what is the big fuss? why would a poor init system steer people away from a distro they have used for years.

can it really be this important? i mean how many times a day are you going to reconfigure start-up services etc...i dont understand this.

I have windows 7 laptop, Dell. I downloaded the newest edition of Ubuntu (Twice)to see if it would install and dual boot beside Windows 7. Unsucessful on several attempts. Once I reboot the computer it will give ma a choice of 7 or Ubuntu. I decide on Ubuntu it starts to boot into Ubuntu than a black screen with all types of Kernel error codes that i'm unfamilur with. one is---(1.292618) kernel panic-not syncing: no working init found.

Try passing init option to Kernel (see Linux Documentation/init.txt for guidance..

I am not sure what all this means any help would be appreactiated...

Hey guys, I am a little confused about run level programs. (concerning centos)

I know when the system boots up the orders will be

bios
MBR
GRUB
kernel
init
runlevel

to my understanding - etc/init looks at /etc/inittab
then where is the run level located?
is it /etc/rc.d/rc0.d...
/etc/rc.d/rc1.d
/etc/rc.d/rc2.d
are these run level programs?

if so, what about /etc/init.d ? doesnt that also execute run level programs?

and how does it know what to start? where does it look

thanks guys just a bit confusing where what looks for what

Hi Team,

I have installed Centos 7 and I feel everything is totally changed.

I am able to see only 3 folders under /etc/init.d/......where as earlier versions have many other init scripts.

I tried installed Minimal & full installation, both have the same situation.

I use Centos 7 and have just installed vsftpd to the server , I want to start vsftp service after install , when I tried the command "systemctl |grep vsftp" , it show nothing .

I use previous , all services keep at /etc/rc.d/init.d , what I need to do is /etc/rc.d/init.d/vsftpd start .

Please advise what I need to do for Centos 7 to start vsftpd ?

thanks

Hi,

I installed ghostscript via yum package manager. Later I wanted a newer version of ghostscript and compiled it from source. "make install" placed the gs executable file under /usr/local/bin/gs. This works if I run the command with absolute path, but if try to run gs, the shell will output

"-bash: /usr/bin/gs: No such file or directory"

if I echo the path variable it will display

/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin

If i run whereis it will give me the correct path
gs: /usr/local/bin/gs

How do I make it work so that typing "gs" will run the executable file from the /usr/local/bin/gs?

(I am using Centos 6)

Thanks.

Hello

I have installed a CentOS 6.4 on VmWare.

Now, after several days of using it, it suddenly does not boots. There is a problem with its initialization, here is the error:

Kernel Panic : Unalble to init. Try passing init= option to the kernel.
Pid 1 : Swapper not tainted.

I have used CentOS.iso to rescue it, but it still does not solve it.

My grub.conf contains:

PHP Code:

#
# Note that you do not have to rerun grub after making changes to this file

How should I solve it then? Thanks in advance
