Error: configure: error: Problem with libXpm.(a|so) or libX11.(a|so)

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

EasyApache Fails Due to YUM Failing

November 15th, 2009 by tech No comments »

EasyApache requires a working package manager to be able to run properly, as it needs to confirm several RPMs are up to date before proceeding with the build.

!! The server's system package manager, 'YUM', failed. !!
!!
This is the command that failed:
	yum --exclude=kernel* -y install aspell aspell-devel automake19 gettext
libstdc++.x86_64 libpng-devel openssl libpng-dev zlib-devel autoconf261
libidn-devel gmake libidn libXpm openssl-devel automake coreutils patch

libXpm-devel sed libXpm-dev lsof krb5-dev flex glibc-dev expat-dev krb5-devel
pspell-devel libstdc++-devel.x64_64 xorg-x11-devel libtool-ltdl libssl-dev

libX11-devel gd cpp xorg-x11-dev gcc ssl-dev autoconf lex
!!
!!
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.

Increase the number of files shown in PureFTPd

November 10th, 2009 by tech No comments »

By default, pure-ftpd limits the amount of files and subdirectory trees to 2,000 files, and 8 levels of directories.

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

LimitRecursion 2000 8

Restart the service to enable any changes made:

/scripts/restartsrv_ftpserver

How to Disable Stats for a Specific User

November 10th, 2009 by tech No comments »

You can disable the stats service (Analog Stats, Awstats or Webalizer) for a specific user by doing the following:

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

How to install rtorrent

November 10th, 2009 by tech 7 comments »

This isn’t really cPanel related, and probably shouldn’t be run from your cPanel production server, but I’m posting nonetheless, as I like to be able to reference this stuff for myself at times :)

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

How to install imagick for PHP

November 10th, 2009 by tech 1 comment »

The imagick.so PHP module can’t currently be installed via PECL, due to it’s inability to write to /var/tmp. 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

How to strace cPanel software

November 10th, 2009 by tech No comments »

From time to time, strange issues pop up which aren’t going to be logged to an error log. 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
