Changes In CentOS 7

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 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 download Centos 6.5 and 6.5 and then install it on Virtualbox , but it is wonder that it do not prompt to ask to select what package need to be install during the installation process .

I checked that only 700M HD space is used to insall , therefore , it should be only minimal installation .

what I have download is CentOS-6.5-i386-bin-DVD1 and CentOS-6.6-i386-bin-DVD1 , the file size is 3.8G .

would advise how can I select package to install or run full install ?

thanks.

Hi all,

Been messing around with my CentOS 6.6 VM trying to break stuff and learn with it. I thought it may be a good learning exercise to (ok, sounds a bit stupid, but purposely) delete /sbin/init to see how I could recover and learn.

I've booted into a recovery CD and recovered the /sbin/init file to my existing directory, however, I'm still having issues booting the machine.

Per Google suggestions, I have given the new init file 755 permissions but it still does not boot.

I apologize that I have not had more ideas, I am currently Googling solutions but am having a bit of trouble knowing where to start. Any suggestions would be greatly appreciated, thank you.

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

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

I am using shinx and i have on instructions to execute a command after server restart from rc.local so i do this:

/usr/local/bin/searchd --config /sphinxconfig/sphinx.conf

But when i restart is not running and it was fine on Centos 6.5

Then i run it manualy from ssh and all are fine ....

I have Windows 8.1 Update as my HOST operating system.
I have installed vmware workstation and installed on it the latest
version of CentOS (7.0) as Guest OS.

I have 8 GIG of RAM and have allocated to VmWare around 5GIG~.
HDD size is 30 GIG.
I also have de-fragmented the HDD.

From the beginning of the installation of the CentOS it was SLOW. It is NOT a sudden change or decline in performance.

Formerly, I had installd CentOS 6.4 which worked OK and had not speed problem while I just had allocated 1 GIG of RAM. Where do you think lies the problem?

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:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file

#          initrd /initrd-[generic-]version.img

 initrd /initramfs-2.6.32-358.el6.x86_64.img 



How should I solve it then? Thanks in advance

Hi,

I am new to the installation of Linux, and wish to install 3 different distro's on the same hard disk.

I have installed Centos 7 successfully as follows :

The /boot is /dev/sda2

/dev/sda1 is listed as unknown so i assume it is the Master Boot Record with Grub installed. I do obtain the option to boot to the various kernels after updating the OS.

/dev/sda3 is a Linux LVM with the various partitions i required.

When i installed the CentOS 7 the installer stated an error about the bootable partition - which was effectively /boot, so i moved this to /dev/sda2.

What i am not sure about is that if i want to install 2 other Linux OS's will i run out of /dev/sdaX assignments ?.

I read somewhere that there are 4 maximum that can be used a /boot (SDA1, SDA2, SDA3, SDA4), so does this mean i can only install one other OS ?.

Any guidance gratefully received. Thanks.

Regards,

Richard.
