GRsec patched kernel install

Fetch the sources:

Download kernel from kernel.org

#wget http://www.kernel.org/pub/linux/kernel/v2.6/longterm/v2.6.32/linux-2.6.32.51.tar.gz

Downlaod latest Grsecurity patch from below URL :

#wget http://grsecurity.net/stable/grsecurity-2.2.2-2.6.32.51-201201021326.patch

Extract:
tar xjf linux-2.6.32.51.tar.gz

Patch the kernel:

#cd linux-2.6.32.51

#patch -p1 < ../grsecurity-2.2.2-2.6.32.51-201201021326.patch

Now start making the kernel :

# make clean && make mrproper

Edit your kernel as per your need :

# make menuconfig

Compile your kernel and install it:

# make bzImage

# make modules

# make modules_install

Make sure it’s working ok with the help of following command :

# depmod 2.6.32.51-grsec

Installing and booting the new kernel :

# cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.32.51-grsec

There is also a file called “System.map” that must be copied to the same boot directory.

# cp System.map /boot

Do not forget to make changes in /etc/grub.conf

also go to grub prompt after this and fire below command :

# grub > savedefault –-default=0 –-once

Now reboot server :

#Shutdown -r now.

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
ffmpeg-php gd support => enabled
ffmpeg libavcodec version => Lavc52.123.0
ffmpeg libavformat version => Lavf52.111.0
ffmpeg swscaler version => SwS0.14.1
ffmpeg.allow_persistent => 0 => 0
ffmpeg.show_warnings => 0 => 0
OLDPWD => /root/ffmpeg-php-0.6.0
_SERVER["OLDPWD"] => /root/ffmpeg-php-0.6.0
_ENV["OLDPWD"] => /root/ffmpeg-php-0.6.0

6. Installation paths

Following are the file system paths of tools that we installed:

ffmpeg: /usr/bin/ffmpeg
mplayer: /usr/bin/mplayer
mencoder: /usr/bin/mencoder
flvtool2: /usr/bin/flvtool2
MP4Box: /usr/bin/MP4Box

Installing ffmpeg-php

Installing ffmpeg-php

Now we are ready to install ffmpeg-php. This can be done in six easy steps:

Download the latest ffmpeg-php release

http://sourceforge.net/projects/ffmpeg-php/files/ffmpeg-php/

Extract the archive:
tar -xjf ffmpeg-php-X.x.x.tbz2
cd ffmpeg-php-X.x.x/
phpize
./configure && make
sudo make install

ffmpeg installation centos

Install FFmpeg on CentOS or RedHat EL 6.x

The following install steps have been proven to work on RedHat Enterprise Linux 6.2. You can check which version you are running with

cat /etc/redhat-release
Additionally, we assume that you are connected and registered with the Red Hat network and/or updated the system with the latest updates from the repositories.

Follow this guide step by step!

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

tcp  0  0 :::11211    :::*  LISTEN      6475/memcached

udp 0  0 0.0.0.0:11211  0.0.0.0:* 6475/memcached

2) Install PHP Extension.

Download and install latest stable memcache version from PECL.

cd /usr/src

wget http://pecl.php.net/get/memcache-2.2.5.tgz

tar zxvf memcache-2.2.5.tgz

cd memcache-2.2.5

phpize

./configure

make

make install

memcache.so will be install in php modules directory, now enable memcache.so extension in php.ini

To find out your php.ini location, execute following command

php -i | grep php.ini

Configuration File (php.ini) Path => /usr/local/lib

Loaded Configuration File => /usr/local/lib/php.ini

vi /usr/local/lib/php.ini

extension = “memcache.so”

save the file and restart httpd server.

/etc/init.d/httpd restart

To check is memcache extension loaded in php, execute following command.

php -i | grep memcache
