RES: ENC: [LON-CAPA-admin] FC5 httpd restart failed

[Stuart Peter Raeburn]

Rodrigo, 

A likely cause of the problem is the ImageMagick and perl-ImageMagick 
modules.  The latest updates (6.2.5.4-4.2.1.fc5.4) available from Fedora FC5 
repositories contain errors which prevent httpd start up. 

I provide a detailed description below with the aim of making this posting 
of more general use. 

If you find the following in /etc/httpd/logs/error_log 

/usr/sbin/httpd: symbol lookup error: 
/usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/Image/Magick/M 
agick.so: undefined symbol: InitializeMagick/usr/sbin/httpd: symbol lookup 
error: 
/usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/Image/Magick/M 
agick.so: undefined symbol: InitializeMagick 

when you use /etc/init.d/httpd start to start the Apache web server on FC5, 
then you need to downgrade ImageMagick. 

Downgrade to the previous versions of required ImageMagick modules as 
follows: 

For 32-bit architecture use:
wget 
http://mirrors.kernel.org/fedora/core/updates/5/i386/ImageMagick-6.2.5.4-4.2 
.1.fc5.3.i386.rpm 

wget
http://mirrors.kernel.org/fedora/core/updates/5/i386/ImageMagick-perl-6.2.5. 
4-4.2.1.fc5.3.i386.rpm 

For 64-bit architecture use:
wget 
http://mirrors.kernel.org/fedora/core/updates/5/x86_64/ImageMagick-6.2.5.4-4 
.2.1.fc5.3.i386.rpm 

and 

wget 
http://mirrors.kernel.org/fedora/core/updates/5/x86_64/ImageMagick-perl-6.2. 
5.4-4.2.1.fc5.3.x86_64.rpm 

to retrieve the .3 versions of the modules, and then use: 

32 bit: 

rpm --oldpackage -Uvh ImageMagick-6.2.5.4-4.2.1.fc5.3.i386.rpm 
ImageMagick-perl-6.2.5.4-4.2.1.fc5.3.i386.rpm 

or 

64 bit: 

rpm --oldpackage -Uvh ImageMagick-6.2.5.4-4.2.1.fc5.3.x86_64.rpm 
ImageMagick-perl-6.2.5.4-4.2.1.fc5.3.x86_64.rpm 

to downgrade the existing rpms. 

You may also wish to add the following line to the [main] section of 
/etc/yum.conf to prevent upgrade of these two Image Magick modules when you 
run yum update in the future, while the .4 versions remain the latest 
updates. 

exclude=ImageMagick* 

This can be removed in the future when the .5 versions appear in the updates 
section of the FC5 repositories which have fixed the error the .4 rpms.
