Errors And Fixes While booting


When I start the centos 6.2 system centos6 logo stucked it didn't give the login prompt
So, I restart the system by CTRL+ALT+DELETE and i pressed the ESC key when circle had come
to see the errors.
The errors are:
  • unexpectedly disconnected from boot status daemon
  • init: prefdm respawning too fast,stopped
In my system may be These errors are because httpd remove/update.

Before this I did following:
I removed httpd by #yum remove httpd*
after that I installed httpd-2.4.10 source file by following some steps.
After i reboot the system i got the above errors.

There are two ways to fix these errors:
  • by rescue installed system from centos 6.2 dvd
  • by upgrade an existing system from centos 6.5 dvd
Rescue installed system:
  • Insert centos 6.2 dvd
  • press F10 key
  • select cd/dvd sta
  • select rescue installed system
  • Language English OK
  • US OK
  • Drive Local cd/dvd OK
  • Enable network interface OK
  • Configure network IPv4 settings manually by giving IP address,Gateway and Nameserver
  • after that press OK until you get command line prompt like bash4.1$
  • $chroot /mnt/sysimage
  • #yum remove httpd*
  • you have to install httpd-2.2.15-29.el6.centos.x86_64
  • Download following rpm packages in another linux system
  • In that goto downloads copy the above three files to one folder and copy that folder to Desktop
  • compress the folder to .zip(httpd.zip)
  • now open terminal
  • #cd /root/Desktop
  • ftp 192.168.1.22 /*your system ip address*/
  • ftp>cd /root
  • ftp>bin
  • ftp>hash
  • ftp>prompt
  • ftp>mput httpd.zip
  • ftp>bye
  • now from your system #cd /root
  • #unzip httpd.zip
  • #rpm -ivh httpd-2.2.15-29.el6.centos.x86_64.rpm
  • #rpm -ivh httpd-devel-2.2.15-29.el6.centos.x86_64.rpm
  • #rpm -ivh httpd-tools-2.2.15-29.el6.centos.x86_64.rpm
  • #sync
  • #exit
  • #reboot
hence problem solved

Description about display manager/How to change display of Centos 6/Rhel/Fedora


There is a configuration file called /etc/sysconfig/desktop. This file defines default display manager and desktop name.
Display manager can be any one of the following:
[a] gnome (gdm)
[b] kde (kdm)
[c] xdm (xdm)
Desktop can be any one of the following
[a] KDE
[b] GNOME
[c] XFCE
Specifying GNOME as a display manager will invoke GDM.
Upon boot, the system will run /etc/init/prefdm.conf which will in turn call the "Preferred Display Manager" (prefdm) script /etc/X11/prefdm which will utilize the settings in /etc/sysconfig/desktop if available.

How to upgrade centos 6.2 to centos 6.5


Upgrade an existing system:

  • Next
  • English Next
  • U.S English Next
  • Select Basic storage devices Next
  • Select upgrade an existing system Next
  • Select Create a new bootloader Next
  • Select centos 6.5 Install
Hence problem solved
After this if you didn't get GUI then
#vi /etc/inittab
Replace 3 with 5 in the last line id:5
#reboot
now you will get the gui
If you feel the desktop is different from the desktop before you used then follow below steps
#vim /etc/sysconfig/desktop
DESKTOP=GNOME
DISPLAYMANAGER=GNOME
#reboot

  2. Using boot disk and edit passwd file.
  3. Mount drive to another system and change passwd file.
 STEP 1. Boot Computer and Interrupt while booting at GRUB stage hitting   ‘arrow‘ keys or “space bar“.

 STEP 2. Type ‘a‘ to modify kernel argument. Anytime you can cancel typing ‘ESC‘ key.

 STEP 3. Append 1 at the end of “rhgb quiet” and press “Enter” key to boot into single user mode.

 STEP 4. Type command “runlevel” to know the the runlevel  

 STEP 5. Type ‘passwd‘ command without username and press ‘Enter‘ key in command prompt. It’ll ask to supply new root password and re-type the same password for confirmation. “Your are Done” Congratulation!!!where you are standing. Here “1 S” state that your are in a single user mode.

How to Encrypt files on centos6/Rhel/Fedora

GNU Privacy Guard (GnuPG) is the backend encryption engine.

Before you can use Gnupg you need to create key pair by "gpg --gen-key"

#gpg --gen-key

gpg (GnuPG) 2.0.14; Copyright (C) 2009 Free Software Foundation, Inc.
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Please select what kind of key you want:
   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)

Your selection? 1

RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 1024
Requested keysize is 1024 bits
Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years

Key is valid for? (0) 2

Key expires at Fri 24 Jul 2015 10:58:51 AM IST
Is this correct? (y/N) y

GnuPG needs to construct a user ID to identify your key.

Real name: shaurya

Email address: xxxxxxxxxx

Comment:xxxxxxxxxxxxxx

You selected this USER-ID:
    "shaurya (xxxxxxxxxxxxxxx) <xxxxxxxxxx>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? o

You need a Passphrase to protect your secret key.
