FFMPEG on CentOS 6 cPanel Server

FFMPEG on CentOS 6 cPanel server




This article describes installation of ffmpeg, flvtool2, mplayer, mencoder, MP4Box, ffmpeg-php and many other video conversion tools on a CentOS 6 server with cPanel hosting control panel.

1. Enable SubHosting.net and EPEL yum repositories

The CentOS 6 RPM packages of ffmpeg, mplayer and MP4Box packages are available on Subhosting.net. These RPM packages are copied from ATrpms and RPM Fusion YUM repositories for a simplified installation.

Some packages on Subhosting.net YUM repo depend on EPEL repo. To enable EPEL repo, install the epel-release RPM package:


rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm


To enable SubHosting.net YUM repository, create the file /etc/yum.repos.d/subhosting.repo and add following repository configuration:


[SubHosting]
name=SubHosting Packages CentOS 6 - $basearch
baseurl=http://dl.subhosting.net/yumrepo/centos/6/$basearch/
enabled=1
gpgcheck=0


Note: with following 'yum' commands, use the switch --exclude "*.i386" on 64-bit systems so as to avoid installing 32-bit packages along with 64-bit packages. Of course, DO NOT use this switch on 32-bit systems.

2. Install ffmpeg mplayer and mencoder

Install these packages using following yum command:


yum install ffmpeg mplayer


Note: there is no separate package for mencoder. It is also provided by mplayer package.

This will also install various dependency packages like libtheora, libvorbis, libogg, lame, opencore-amr, x264, xvidcore etc.

3. Install flvtool2

cPanel has its own ruby installer script. So install ruby using following cPanel script:


/scripts/installruby


Flvtool2 is available as a Ruby Gems package. Use following gem command to install flvtool2:


gem install flvtool2


4. Install MP4Box2

MP4Box is provided by gpac package. Install gpac and its library packages:


yum install gpac gpac-libs


5. Install ffmpeg-php

Ffmpeg-php requires ffmpeg development package. Install it using yum:


yum install ffmpeg-devel


Now download the latest ffmpeg-php package:


wget http://downloads.sourceforge.net/ffmpeg-php/ffmpeg-php-0.6.0.tbz2


Untar this package, build and install it with following commands:


tar xjf ffmpeg-php-0.6.0.tbz2
cd ffmpeg-php-0.6.0
sed -i ‘s/PIX_FMT_RGBA32/PIX_FMT_RGB32/g’ ffmpeg_frame.c
phpize
./configure
make
make install


The make install command will show PHP extensions path where ffmpeg PHP extension is installed:


root@server [~/ffmpeg-php-0.6.0]# make install
Installing shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-20060613/


Now edit php.ini file (/usr/local/lib/php.ini) and make sure that value of extension_dir is set to PHP extension directory as given by above make install command:


extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613"


Add following line just below extension_dir and this will enable ffmpeg PHP extension:


extension="ffmpeg.so"


Restart Apache to make this change effective:


/scripts/restartsrv_httpd


You can verify the status of ffmpeg extension on a PHP info web page or from command line as given below:


root@server [~]# php -i | grep ffmpeg
ffmpeg
ffmpeg-php version => 0.6.0-svn
ffmpeg-php built on => Jun 2 2012 20:48:04

Memcached installation

http://www.sohailriaz.com/how-to-install-memcached-with-memcache-php-extension-on-centos-5x/

1) Install memcached.

Enable rpmforge respository to install latest memcached rpm using yum.

For i386 / i686

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

For x86_64

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

Use yum to install memcached

yum -y install memcached

As soon as memcached installation completed, edit options for memcached in /etc/sysconfig/memcached to meet your need.

vi /etc/sysconfig/memcached

PORT=”11211″ #define on which port to urn

USER=”nobody” #same as apache user

MAXCONN=”1024″ #maximum number of connections allowed

CACHESIZE=”64″ #memory used for caching

OPTIONS=”" #use for any custom options

Save the file. All options can be seen by using following command

memcached -h

Start memcached

/etc/init.d/memcached start

Starting Distributed memory caching (memcached): [ OK ]

to check the running status of memcached

/etc/init.d/memcached status

memcached (pid 6475) is running…

and

netstat -anp | grep 11211

Setting password for mysql user in .my.cnf

Setting password for mysql user in .my.cnf

Sometimes you want automated access for root on your MySQL database. One way of accomplishing that is by doing this:

# cd /root
# touch .my.cnf
# chmod 640 .my.cnf

And put in it:

[client]
user=root
password=<password of mysql root user>
Once you have done the following steps, the root user can login to mysql as root user without giving password.
root@server [~]# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 749
Server version: 5.1.68-cll MySQL Community Server (GPL)

Hide Apache, PHP and Bind Versions

Hide Apache, PHP and Bind Versions
To Check Apache Version:

By default, Apache will send version and modules information like mod_php, mod_perl, mod_ssl in every HTTP header.

If you want to view Apache web server version and sofware of a remote server, follow this procedure.

# telnet example.com 80

Trying example.com...
Connected to example.com.
Escape character is ‘^]'.
HEAD / HTTP/1.0 <- after this press 2 times ENTER
HTTP/1.1 200 OK
Date: Sun, 07 Oct 2012 12:57:57 GMT
Server: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 JRun/4.0
Last-Modified: Tue, 03 Jan 2012 11:41:16 GMT
Connection: close
Content-Type: text/html; charset=UTF-8
Connection closed by foreign host.

In the above example it is showing all the details about your web server and php this is not recommended for security reasons.We need to hide this information with the following procedure.
To Hide Apache Information:
To hide the information, add the following two apache directives in Apache configuration file, (httpd.conf or apache2.conf)

ServerTokens ProductOnly

ServerSignature Off

# /etc/init.d/httpd restart

Now the output for apache header looks like below

Server: Apache
To Hide PHP Version Details

Locate php.ini loaded in the server.

Change the following option in php.ini

expose_php On

to

expose_php Off

# /etc/init.d/httpd restart
To Hide BIND Version
You can check the Bind version of a server by using the following command.

# dig +short @XXX.XXX.XXX.XXX -c CH -t txt version.bind
"9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.4"

To hide your version of bind, change the version value in named.conf as like the following.
You can give any string for the version.

options {
directory "/var/named";
version "We Just Hide It";
};

# dig +short @XXX.XXX.XXX.XXX -c CH -t txt version.bind
"We Just Hide It"
