RHEL 5.6 compile and install the 3.2.9 Kernel

Step 6:

1/download the kernel 3.2.9 kernel.org and decompress it to/usr/src:

[root@localhost src]# ls -latotal 141172drwxr-xr-x  6 root root     4096 Mar 11 19:31 .drwxr-xr-x 15 root root     4096 Mar 10 09:55 ..drwxr-xr-x  2 root root     4096 Oct  1  2009 debugdrwxr-xr-x  3 root root     4096 Mar 10 09:56 kernelsdrwxrwxr-x 23 root root     4096 Mar 11 19:27 linux-3.2.9-rwxrw-rw-  1 root root 78132997 Mar 11 09:48 linux-3.2.9.tar.bz2drwxr-xr-x  7 root root     4096 Mar 10 09:57 redhat

2/make gconfig. Save and exit without any modification. The. config file is generated locally and modified as follows:

1,

Change config_sysfs_deprecated to config_sysfs_deprecated = y.

Or

2,

Use make menuconfig to select the following options

General setup -->              [*] enable deprecated sysfs features to support old userspace tools

Otherwise, the new kernel of some systems cannot be started. Generally, the direct consequence is that the new kernel cannot be started:

Enter y to start compilation.

4/make modules_install: copy the Lib file to/lib/modules:

[Root @ localhost linux-3.2.9] # ls/lib/modules/

5/make install

You can.

Modify the startup directory:

1 # grub.conf generated by anaconda  2 #  3 # Note that you do not have to rerun grub after making changes to this file  4 # NOTICE:  You do not have a /boot partition.  This means that  5 #          all kernel and initrd paths are relative to /, eg.  6 #          root (hd0,0)  7 #          kernel /boot/vmlinuz-version ro root=/dev/sda1  8 #          initrd /boot/initrd-version.img  9 #boot=/dev/sda 10 default=0 11 timeout=5 12 splashimage=(hd0,0)/boot/grub/splash.xpm.gz 13 hiddenmenu 14 title Red Hat Enterprise Linux Server (3.2.9) 15     root (hd0,0) 16     kernel /boot/vmlinuz-3.2.9 ro root=LABEL=/ rhgb quiet crashkernel=128M@16M 17     initrd /boot/initrd-3.2.9.img 18 title Red Hat Enterprise Linux Server (2.6.18-238.el5) 19     root (hd0,0) 20     kernel /boot/vmlinuz-2.6.18-238.el5 ro root=LABEL=/ rhgb quiet crashkernel=128M@16M 21     initrd /boot/initrd-2.6.18-238.el5.img
