1.5.3. Installing Signed Packages

Installation for most packages can be done safely (except kernel packages) by issuing the following command as root: 
rpm -Uvh <package>…
For example, to install all packages in a new directory, called updates/, under the /tmp directory, run: 
~]# rpm -Uvh /tmp/updates/*.rpm
Preparing...                ########################################### [100%]
   1:alsa-lib               ########################################### [ 33%]
   2:alsa-utils             ########################################### [ 67%]
   3:aspell                 ########################################### [100%]
For kernel packages, as root use the command in the following form: 
rpm -ivh <kernel-package>
For example, to install kernel-2.6.32-220.el6.x86_64.rpm, type the following at a shell prompt: 
~]# rpm -ivh /tmp/updates/kernel-2.6.32-220.el6.x86_64.rpm
Preparing...                ########################################### [100%]
   1:kernel                 ########################################### [100%]
Once the machine has been safely rebooted using the new kernel, the old kernel may be removed using the following command: 
rpm -e <old-kernel-package>
For instance, to remove kernel-2.6.32-206.el6.x86_64, type: 
~]# rpm -e kernel-2.6.32-206.el6.x86_64
Alternatively, to install packages with Yum, run, as root, the following command: 
~]# yum install kernel-2.6.32-220.el6.x86_64.rpm
To install local packages with Yum, run, as root, the following command: 
~]# yum localinstall /root/updates/emacs-23.1-21.el6_2.3.x86_64.rpm

Note

It is not a requirement that the old kernel be removed. The default boot loader, GRUB, allows for multiple kernels to be installed, then chosen from a menu at boot time.

Important

Before installing any security errata, be sure to read any special instructions contained in the errata report and execute them accordingly. Refer to Section 1.5.4, “Applying the Changes” for general instructions about applying the changes made by an errata update.
