How do I install a kernel from the RPM?

I tried with rpm -ivh, and its says it installed it, but it doesn't add anything to /etc/grub.conf, and it doesn't add an files to /usr/src/kernels.

TIA

Code:

[root@l ~]# rpm -ivh kernel-2.6.18-194.11.1.el5.src.rpm 
warning: kernel-2.6.18-194.11.1.el5.src.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

You have kernel source package, not a compiled one. kernel-2.6.18-194.11.1.el5.src.rpm.

Either you have compile the source yourself, or get the right package.

A bit more information about your system would have been helpful...

In KDE (and possibly Gnome) open the file manager (Konqueror) and click on the rpm -- OpenSuSE then installs everything properly. The rpm command per se is not aware of /boot/grub/menu.lst.

Well you only installed the source code and it should be someplace in /usr/src/redhat/SOURCES.
The rpm should not have something like kerne_xxx.src.rpm, it should be similar to this: kernel-2.6.18-194.11.3.el5.rpm, without "src" which means source code.

"kernel-2.6.18-194.11.1.el5.src.rpm " besides being a SRC -not compiled SOURCE CODE only rpm it is also OLD and NOT the current

2.6.18-194.11.3.el5.centos.plus is the current
if what you want is the kernel source to build a kmod then use yum

Code:

yum install kernel-devel
yum update

reboot seeing as a new kernel will have been installed

Thanks!

I assumed it compiled it automatically and also put the source files on the box.

yum won't work, because this server is not directly connected to the Internet.

I downloaded the kernel from here:
http://mirror.centos.org/centos/5.5/...s/x86_64/RPMS/
and it worked.

Code:

[root@l ~]# rpm -ivh kernel-2.6.18-194.11.3.el5.x86_64.rpm 
warning: kernel-2.6.18-194.11.3.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

Now that is interesting. SuSE doesn't do changes in menu.lst when you insert a kernel via rpm. Must be a RedHat / anaconda trick. Good for you, saves work

Gotta love redhat

JZL240I-U · 09-09-2010, 07:16 AM

Well, in SuSE you use

Code:

yast -i <kernel.rpm>

Then you may love Susie as well
