Accidently removed the RPM DB
 

I Accidently removed the RPM DB in remote RHEL 4 server. I used command list following commands on remote server.

# rpm -e rpm -e MySQL-shared-5.0.45-0.glibc23
# rpm -e rpm -e MySQL-shared-5.0.45-0.glibc23 -nodeps
# rpm -e rpm -e MySQL-shared-5.0.45-0.glibc23 --nodeps

After did above command
#rpm
-bash: rpm: command not found

I did this on remote cpanel installed server

That's because you repeated
rpm -e
you only need it once per line for the MySQL stuff.
rpm -e rpm
removed the rpm

hopefully somewhere in the menus there'll be an rpm install option.

Hey There,

You can grab the RPM rpm file and use rpm2cpio to extract it and install it.

rpm2cpio /dir with/your/rpm-*.rpm | cpio -dimv

otherwise, boot off of your rescue cd ("linux rescue") and mount your root partition (/dev/hda or whatever it is), then chroot that mountpoint so it appears to be / and you can reinstall the rpm package using the rpm binary on your rescue cd.

Hope that helps!
