Fedora doesnt get to Login Screen

[linuxuser3000]

Hi I have Fedora on a Drive that that has been running fine as a server until I added a program path environment to bashrc something like PATH:$APPLICATIONNAME... which has screwed everything up. I've been running the setup for a couple of years and everything was running sweet. So hopefully a nice person out there can get me back on the road


Heres the the setup

1000 GB Hard Disk
|WD My Book 1110
|MBR Partition Table
|
|___210 MB Filesystem
| Linux Ext4 (version 1.0) Type Linux(0x83) Bootable
|
|___80 GB LVM2 Physical Volume Type Linux LVM (0x8e)
| 80 GB
|
|___SPACE
919 GB FAT (32-bit version) Type W95 FAT32 (0x0b) Bootable

On the installation I created a user drqueue and a drqueue.localdomain on the 80GB partition which is used as the server part (there are NFS shares, samba setup etc ).

//to try and rectify things

I went into the F9 on startup and edited the GRUB and accessed the /etc/bashrc file using vi bash. This bashrc file is on the 80GB partition ( I can see all my other files using ls)
and made sure it had PATH= $PATH:/bin:/usr/bin:/usr/local/bin:/usr/lib/qt-3.3:/usr/local/drqueue/software/bin:/sbin to try and correct things but it made no difference.

What should happen is I should get to the login screen with drqueue.localdomain. At the moment things just get paused on a fedora screen.


I ran df-h in GRUB and get this


Filesystem____________________________Size____ Used______Avail Use____________Mounted on
/dev/mapper/vg_may-lv_root _____ 70G_____ 48G_______22G_____69%_____ /
tmpfs _____ 881M____ 0 ___881M___0%______ /dev/shm

Start the system with a recovery disc or live CD/DVD/USB, mount the root file system, and edit the bashrc file to remove the new path. Then, simply reboot.

[linuxuser3000]

Thanks for the reply, I'm reading through
i'm having a read through docs.fedoraproject.org/en-US/Fedora/13/html/Installation_Guide/s1-rescuemode-boot.html]17.2.*Booting into Rescue Mode


Can you clarify - is the root file system on the 210MB partition? I dont quite understand the read out from df-h where it says "/dev/mapper/vg_may-lv_root" mounted on "/"
I thought "/" is the root and how can it be the root on the 210MB partition if it is 70G in size. or is the root "/boot" on dev/sda1

What is workflow to mount the root file system after installing the installation disc? Is the root file system something you can't edit when your in the grub? And also is there a bashrc on the 210MB as well as the one I've edited on the 80GB partition? Sorry for all the newbie sounding questions. I've been using Linux for a couple of years and lot of it still feels opaque to me!!

[atreyu]

No, the root filesystem, "/", is on your /dev/mapper/vg_may-lv_root partition (yours is 80GB).

The /dev/sda1 partition is mounted at /boot. The /boot partition (210MB in your case) contains grub loader and config files, bootable kernels and kernel-related files. All profile files (/etc/bashrc, ~/.bashrc, etc.) will be in the root ("/") filesystem.

The init process mounts your root partition for you, after the kernel is done loading. You don't have to do anything to make it happen (and you shouldn't want to). I don't know if you can edit the filesystem within grub - I wouldn't if I could.

If I were you, I'd try appending init=/bin/sh to the kernel boot arguments at the grub boot prompt. After the kernel loads, that should skip the most of the init process and drop you right to a simple bash prompt w/o reading any (bad) profile scripts. Then you should be able to edit whatever you did and then reboot.

[linuxuser3000]

ok I can now get fully into Linux - I removed export PATH=$APPLICATIONNAME/bin from the /etc/profile file. which caused the issue.

I have a different issue now
What I used to get and what I want is

"[root@drqueue drqueue]#" when ever I opened terminal

now I get "bash-4.0#"

Any suggestions how I can get back what it should it be??

[atreyu]

What you are missing is the nice custom prompt (PS1). Sounds like one of your profile scripts got mangled. Check the output of this command for any modified files:

rpm -qV setup

The setup package owns /etc/profile and /etc/bashrc, amongst others. If the rpm command lists any of them as modified, post their contents. Also, look for the existence of these files, and examine them for problems. You can put 'set -x' at the top of them to see what is going on.

~/.bashrc
~/.profile
~/.bash_profile

If you're not sure, you can post the contents of them and we'll look at them.

Also note that any scripts in /etc/profile.d/*.sh exist, they will get sourced, too - so if one of them is borked, you may see problems.

[linuxuser3000]

Hi Atreyu, thanks for the reply and any further advice.
rpm -qV setup give me

So according to the output of the rpm verification command, your /etc/bashrc and /etc/profile have changed. Can you post their contents?

If you want, you can also just reinstall that package, which will replace those files:

rpm -e --justdb --nodeps setup
yum install setup

Above is untested - the setup package is fairly important, so no idea if that will work, flat-line your system, etc. - you've been warned!

Also, be sure to check out the other login scripts in /root, as I mentioned.

When change the PATH environment to add something to the current PATH, then enclose the PATH variable in curly braces, as in:

export PATH=newdir1:${PATH}:newdir2

This is the, AFAIK, the only safe way to recursively define $PATH.
