Forcing linux kernel 3 to recognize cdrom as hdX on centos

+1 vote
580 views

I have a problem with older version of anaconda linux installer. I have upgraded kernel in my distro, but, when this anaconda boot with new 3.4.52 kernel, can NOT find cdrom. As far as I understand, this is because the new kernel recognize cd drive as srX, scdX instead of older hdX with 2.6.18. At the moment I can not upgrade anaconda and forced this kernel to recognize it as before.

Are there any kernel command line argument, kernel config or something else for kernel 3.4.52 to recognize this cdrom as hdX?

I think you need to write some udev rules to name the device differently. Refer to the following:

Actually I have tried lots of things. As far as I see, this is not as simple as a symlink. Anaconda C application find CDROM according to some info provided by kernel. Also, Anaconda stage1 has a very limited debug option. I have possibilities to recompile kernel with some options or run kickstart with some kernel arguments.

If you have references to cdrom in your kickstart file, try to change them to match the device name being
assigned by the kernel.

How best to install path.py package in Python 3.4 environment on Centos 5?

I want to install path.py in my Python 3.4 environment on a Centos 5 box. My /usr/local/bin/ contains: 

easy_install-3.4 
python3.4  
etc.

We are behind a proxy server and I tried this: 

# /usr/local/bin/easy_install-3.4 path.py 

Searching for path.py 
Reading https://pypi.python.org/simple/path.py/ 
Download error on https://pypi.python.org/simple/path.py/: hostname '172.29.68.1  
' doesn't match either of 'www.python.org', 'python.org', 'pypi.python.org',  
'docs.python.org', 'testpypi.python.org', 'bugs.python.org', 'wiki.python.org',  
'hg.python.org', 'mail.python.org', 'packaging.python.org', 'pythonhosted.org',  
'www.pythonhosted.org', 'test.pythonhosted.org', 'us.pycon.org', 'id.python.org' --  
Some packages may not be found!

Couldn't find index page for 'path.py' (maybe misspelled?), Am I best to use pip or easy_install? also if easy_install, how can I fix the above error?

CentOS 6.6 64-bit won't install on a 3 TB disk

I'm having an issue getting a C6.6 install to work on a 3 TB dual hard drive system, raid 0. I'm hoping that someone here can help.

So, I install as normal, but then reboot, and it comes to a grub prompt. Going into the system via Linux rescue, I see that most of the files dealing with the kernel haven't been installed.

I asked the maker of the server and he said that they have noticed this happen recently. A solution is to put the kernel files on a thumb drive, and then point the OS to look for them there.

I have yet to try it, but is there a better way to deal with this issue that anyone else has done?

Change sudoers remotely on CentOS Linux

I've been asked to give someone sudo rights across an entire environment without the benefit of something like puppet or chef or cfengine et al.

What I've come up with so far is this:

ssh -t miaprbicsra04v sudo -S /bin/echo "rsherman ALL=(ALL) NOPASSWD: /sbin/service /bin/rm /usr/bin/du /bin/df" >> sudo tee /etc/sudoers

Right now that's just to one host, but I plan on substituting a list of hosts once I get farther along. Problem is, the output hangs on the tee command. Not sure why. Any suggestions?
