This happens most times when compiling with gd enabled for the first time. Reinstall X11 libraries and try again:

cd /usr/ports/x11/libX11/
make deinstall
make install

!! The server's system package manager, 'YUM', failed. !!
!!
This is the command that failed:
	yum --exclude=kernel* -y install aspell aspell-devel automake19 gettext

!!
Since EasyApache was unable to resolve it automatically you should:
	1) Manually run the failed YUM command (shown above) via SSH
        2) See if your particular error is addressed at 

http://www.cpanel.net/support/could_not_ensurepkgs.htm

	3) Resolve the YUM problem manually
	4) Re-run EasyApache
!!
!! Please visit 

http://www.cpanel.net/support/could_not_ensurepkgs.htm

 for help with this error. !!

!! Restoring original working apache !!

First things first. Try running ‘yum -y update’ and see if it completes. You may see the following when running yum update.

error: rpmdbNextIterator: skipping h#      27 region trailer: BAD, tag 1507328 type 1507328 offset -1507328 count 1507328
error: rpmdbNextIterator: skipping h#      65 region trailer: BAD, tag 724250418 type 825833527 offset -740320047 count 842150704
error: rpmdbNextIterator: skipping h#      69 region trailer: BAD, tag 942410249 type 1952543335 offset -1702113073 count 842610488

and so on and so on….

Then it’ll actually show packages that require updates, and experience a segmentation fault.

---> Package hotplug.x86_64 3:2004_04_01-7.10 set to be updated
---> Package fetchmail.x86_64 0:6.2.5-6.0.1.el4_8.1 set to be updated
--> Running transaction check
Segmentation fault
[root@vps ~]#

This means that your RPM database is corrupt, which is easily fixed with the following:

[root@vps ~]#rm -f /var/lib/rpm/__db.*
[root@vps ~]#rpm -vv --rebuilddb

Once that finishes, run ‘yum update’ again, and it should complete successfully. If so, you’re all set. Go ahead and retry your easyapache build.

This can be changed in /etc/pure-ftpd.conf:

LimitRecursion 2000 8

Restart the service to enable any changes made:

1) Login to your server via ssh.

2) Edit /var/cpanel/users/username, and add any of the following, as needed:

skipanalog=1
skipawstats=1
skipwebalizer=1

3) Now we’ll restart the cPanel service:

/etc/init.d/cpanel restart

If you don’t want to compile rtorrent from source, you can install via RPM by adding Fedora’s EPEL repository:

http://fedoraproject.org/wiki/EPEL/FAQ#howtouse

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
yum install libtorrent rtorrent libsigc++20-devel

To get around that, you can install it manuall:

# yum install ImageM* netpbm gd gd-* libjpeg libexif gcc coreutils make
# cd /usr/local/src
# wget http://pecl.php.net/get/imagick-2.2.2.tgz
# tar zxvf ./imagick-2.2.2.tgz
# cd imagick-2.2.2
# phpize
# ./configure
# make
# make test
# make install

This will compile imagick.so, and move it to your extensions directory specified in php.ini. Now you’ll need to add the following to php.ini:

extension=imagick.so

and restart apache:

/scripts/restartsrv_httpd

For some of the more “hard to track down” issues, you can use strace to see just what the process is doing, and where your issue might be.

This article won’t go into how to read straces, as there are many other articles written about this, but I’ll provide a good base from which to start.

strace -v -o /root/strace.cpanel -f -s 4096 -p `cat /var/run/cpsrvd.pid`

That command uses several flags, outputting the strace to a file called strace.cpanel.

-v enables a more verbose output
-o specifies the file to output the contents to. If not specified, it will output directly to your terminal.
-f includes all processes forked by the process you’re stracing
-p will specify the PID. In this case, we’re going to cat the pic from cpsrvd.pid
