Q. I see following message in my logs files:

My server hangs occasionally after rebooting with above message in /var/log/message. How do I get rid of this problem under CentOS Linux / RHEL version 4.x?

RHEL 4: Find up2date command module / library dependencies

Posted on in Categories , last updated November 9, 2007

Q. I’m using RHEL 4.x as database server. How can I run the up2date command to find out what package will satisfy library / module dependencies via RHN?

A.Update Agent provides a complete system for updating the RPM packages installed on a Red Hat Enterprise Linux system. Both command line and graphical interfaces are included.

Update Agent has a quite a few configuration options, including but not limited to: installing packages after they are downloaded; downloading source RPMs along with binary RPMs; whether or not to upgrade packages where the default configuration file(s) have been modified, and more.

–whatprovides=<dependencies> option

Use the following syntax to query the RHN servers to resolve the comma separated list of dependencies. It will return a list of packages that will satisfy these dependencies:

up2date --whatprovides=<dependencies>

For example, if an error read as follows:

error: failed dependencies:
      libxyz.so    is needed by httpd
      libabc.so.1  is needed by httpd

To find out all libs or module dependencies in any of the package, enter:
# up2date --whatprovides=libxyz.so,libabc.so.1
Output:

packagename-1.15

Now just install packagename-1.15:
# up2date packagename

Redhat Enterprise Linux (RHEL) install ImageMagick RPM for manipulating images

Q. How do I install ImageMagick software under Redhat enterprise Linux version 4 update 5?

A. ImageMagick is an image display and manipulation tool for the X Window System. ImageMagick can read and write JPEG, TIFF, PNM, GIF, and Photo CD image formats. It can resize, rotate, sharpen, color reduce, or add special effects to an image, and when finished you can either save the completed work in the original format or a different
one. ImageMagick also includes command line programs for creating animated or transparent .gifs, creating composite images, creating thumbnail images, and more.

ImageMagick is one of your choices if you need a program to manipulate and display images. If you want to develop your own applications which use ImageMagick code or APIs, you need to install ImageMagick-devel as well.

INSTALL ImageMagick

Use up2date command to install ImageMagick, enter ( <= RHEL 4 only): # up2date install ImageMagick
OR use yum if you are using Fedora Core/CentOS/RHEL 5:
# yum install ImageMagick
