To reduce the CPU usage of your account, there are several general rules that you should follow:

Upgrade all third-party web applications to the latest stable release available (Drupal, Joomla, Word Press and any other content management or blog systems, forums, galleries or any other scripts that you have installed on your account)
Check to see if any of the web applications that you use have add-ons or plugins, and make sure they are upgraded to the latest available versions
Perform a general house-keeping and remove any unused web applications and/or plugins/add-ons that you have installed
Any web applications that allow caching should have this feature enabled or activated.
If you have developed your own script(s), try reducing the number of MySQL/MSSQL/ PostgreSQL queries and optimize your scripts to use less processing time.

To deal with and reduce a high CPU usage on your hosting account, you must in the first instance identify the reasons for the high CPU usage. Identifying these reasons can be quite difficult, most especially if you are using third-party web applications such as forums, content management or blog systems, which you have not developed yourself, and have little or no knowledge about how they use system resources.

What exactly is CPU Usage and What does it mean to your hosting account? CPU time (or CPU usage, processing time) is the amount of time for which a central processing unit (CPU) was used for processing instructions of a computer program, as opposed to, for example, waiting for input/output operations.
The web server's CPU is used to obtain and serve your web pages to your visitors, whether these pages are static or dynamic is totally irrelevant. More CPU cycles or resources are used when your web pages are served dynamically from a database or script, since the database has to do some fair amount of processing to construct and serve these web pages to the visitors. It has to load the web template, obtain data for that particular page from the database, execute any plugins or modules that you have installed, and finally package the page to be served to your website visitors.
CPU time is a finite resource shared by all websites hosted on a particular web server, if any one website uses the CPU excessively; other websites on the same server will be deprived the opportunity to serve their pages in a timely manner, and will often appear either appear to be sluggish.
As a result of this, we usually monitor the amount of CPU your site uses on shared web hosting plans, to curb problems when a single website uses too much of the CPU time, adversely affecting other websites on the same server. Each hosting account has a CPU usage limit, which, when reached, may result in the account being suspended.

Login to your server as root
and run
Code:

Quote:yum -y update

Before installing DirectAdmin, there are some basic programs that you'll need. The following are the typical commands used before we install DirectAdmin.

On Rehat/Fedora/CentOS:
Code:

Quote:yum install wget gcc gcc-c++ flex bison make bind bind-libs bind-utils openssl openssl-devel perl quota libaio libcom_err-devel libcurl-devel gd zlib-devel zip unzip libcap-devel cronie bzip2 db4-devel cyrus-sasl-devel perl-ExtUtils-Embed

Once its complete

Code:

Quote:wget http://www.directadmin.com/setup.sh
chmod 755 setup.sh
./setup.sh

you will be prompted for a client ID number, license ID number, and hostname.

After the setup routine starts you will be presented with a number of options. You should have your license details ready.

Important: The hostname should not be the same as the primary domain name. e.g. server9x.com is not a valid hostname, where myserver.server9x.com is. Having the same host/main domain name will cause e-mail and FTP problems. Also, please make sure the hostname resolves once you setup DNS.

When the install routine has completed, you should be ready to login to your newly installed control panel via:http://xx.xx.xx.xx:2222 (where xx.xx.xx.xx is your IP address or domain name). 2222 is the port DirectAdmin normally communicates on. It is important to keep this port open in your firewall
In case you forgot your admin password enter the following:

Code:

/usr/local/directadmin
./directadmin i

3. update custombuild:
After having DirectAdmin succesfully installed it is now time to secure your server. A good first step would be to install the CSF Firewall. It is also important to periodically update your server. This can be done by issuing the following commands:

Code:

cd /usr/local/directadmin/custombuild
./build clean
./build update
./build update_versions

4. Dealing with RPM errors
When installing RPMs, errors can sometimes occur. Don't panic, solving them is usually easy. If you didn't know what to install during your RedHat installation, you might have installed a few services, such as apache and sendmail. These services must be removed before the rpm will be able to be installed.
For example, lets say you are trying to install exim and you get the following:

Code:

rpm -ivh exim-3.36-2.i386.rpm
  Preparing...                         ########################################### [100%]
  file /somefile from install of exim-3.36-2 conflicts with file from package sendmail-8.1

This would mean that sendmail is already installed on your server and you must remove it. This can easily be accomplished by running the following:

Code:

rpm -e --nodeps sendmail

Then you will be able to install your rpm. This follows for other services such as apache, apache-devel, wu-ftp, php, MySQL and so forth. If you need to figure out if you already have a service installed, you can run

Code:

rpm -q servicename
or
rpm -qa | grep substring
Where substring is just a word. For example, using "apache" might return:
rpm -qa | grep apache
apache-fp-1.3.27-2
apache-fp-devel-1.3.27-2
apache-fp-manual-1.3.27-2

This guide is based on a minimal CentOS installation and will install FFmpeg with several external encoding libraries. This guide is kept relatively up to date with FFmpeg development and library sources (see the page history for changelog), and should also work for recent Red Hat Enterprise Linux (RHEL) and Fedora.

Note: The # indicates that the command should be executed as superuser or root.
Preparation ¶

Remove any existing packages:
Code:

Code:

# yum erase ffmpeg x264 x264-devel

Get the dependencies:
Code:

Code:

# yum install gcc git make nasm pkgconfig wget zlib-devel

Make a source directory:
Code:

Code:

mkdir ~/ffmpeg-source

Installation ¶

Yasm ¶

Yasm is an assembler used by x264 and FFmpeg.
Code:

Code:

cd ~/ffmpeg-sourcewget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gztar xzvf yasm-1.2.0.tar.gzcd yasm-1.2.0./configuremake# make install

Note: If you do not require certain encoders you may skip the relevant section and then remove the appropriate ./configure option in FFmpeg. For example, if libvorbis is not needed, then skip that section and then remove --enable-libvorbis from the Install FFmpeg section.
x264 ¶

H.264 video encoder.
Code:

Code:

cd ~/ffmpeg-sourcegit clone git:/git.videolan.org/x264cd x264./configure --enable-staticmake# make install

LAME ¶

Code:

Code:

cd ~/ffmpeg-sourcewget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gztar xzvf lame-3.99.5.tar.gzcd lame-3.99.5./configure --disable-shared --enable-nasmmake# make install

libogg ¶

Required for libvorbis.
Code:

Code:

cd ~/ffmpeg-sourcewget http://downloads.xiph.org/releases/ogg/libogg-1.3.0.tar.gztar xzvf libogg-1.3.0.tar.gzcd libogg-1.3.0./configure --disable-sharedmake# make install

libvorbis ¶

Vorbis audio encoder.
Code:

Code:

cd ~/ffmpeg-sourcewget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.3.tar.gztar xzvf libvorbis-1.3.3.tar.gzcd libvorbis-1.3.3./configure --disable-sharedmake# make install

libvpx ¶

VP8 video encoder.
Code:

Code:

cd ~/ffmpeg-sourcegit clone http://git.chromium.org/webm/libvpx.gitcd libvpx./configuremake# make install

FFmpeg ¶
Code:

Code:

cd ~/ffmpeg-sourcegit clone git:/source.ffmpeg.org/ffmpegcd ffmpeg./configure --enable-gpl --enable-libmp3lame --enable-libvorbis --enable-libvpx --enable-libx264make# make install

Compilation is now complete and ffmpeg should now be ready to use. The rest of this guide shows how to update or remove FFmpeg.

Note: Keep the ffmpeg-source directory and all contents if you intend to update or uninstall as shown below.
Updating x264, libvpx, and FFmpeg ¶

First uninstall x264, libvpx, and FFmpeg:
Code:

Code:

cd ~/ffmpeg-source/x264# make uninstallcd ~/ffmpeg-source/ffmpeg# make uninstallcd ~/ffmpeg-source/libvpx# make uninstall

Its now quite easy to migrate accounts from cPanel to DirectAdmin using conversion tool

Before proceed, First we will need to download conversion tool and you can download it from here ::

DOWNLOAD HERE

STEPS TO FOLLOW ::
1) Download and extract the version URL (from above) that you wish to use. (wget and tar xzf)

2) Create import and export directories for the tool to use. (mkdir import export)

3) Copy your cPanel user backups into the import directory.

4) Edit defaults.conf to match the DAserver you will be restoring to. The only fields you must change are theIP and name server fields. The tool will not work if you fail to dothis!

5) Execute perl da.cpanel.import.pl and follow the on-screen instructions (which will duplicate the steps here to a degree).

6) After the tool is finished converting (or as it completes each individual user), move your new DA user backups from the export directory to any DA /home/RESELLER/user_backups directory*

7) Restore the DA user backups in DA’s reseller-level Manage User Backups tool.

You are done now [Image: icon_smile.gif]
