=======

1.Create a new Directory under the src folder

mkdir /usr/local/src/ffmpeg
cd /usr/local/src/ffmpeg

2.Download all the Sources

wget http://www3.mplayerhq.hu/MPlayer/releases/codecs/essential-20061022.tar.bz2

wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.1.2.tar.gz

3.Uncompress all the source files

bunzip2 essential-20061022.tar.bz2; tar xvf essential-20061022.tar
tar zxvf flvtool2_1.0.5_rc6.tgz
tar zxvf lame-3.97.tar.gz
bunzip2 ffmpeg-php-0.5.0.tbz2; tar xvf ffmpeg-php-0.5.0.tar
tar zxvf libogg-1.1.3.tar.gz
tar zxvf libvorbis-1.1.2.tar.gz

4.Create the new codecs directory and move the codecs

mkdir /usr/local/lib/codecs/
mv essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

5.Install SVN and Ruby

yum install subversion
yum install ruby
yum install ncurses-devel

6.Download the latest FFMPEG and Mplayer from the subversion

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

7.Compile LAME

cd /usr/local/src/ffmpeg/lame-3.97
./configure
make
make install

8.Compile libOGG

cd /usr/local/src/ffmpeg/libogg-1.1.3
./configure
make
make install

9.Compile libVorbis

cd /usr/local/src/ffmpeg/libvorbis-1.1.2
./configure
make
make install

10.Compile flvtool2

cd /usr/local/src/ffmpeg/flvtool2_1.0.5_rc6
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

11.Compile MPlayer

cd /usr/local/src/ffmpeg/mplayer
./configure
make
make install

12.Compile FFMPEG

cd /usr/local/src/ffmpeg/ffmpeg
./configure --enable-libmp3lame --enable-libogg --enable-libvorbis --disable-mmx
--enable-shared
echo '#define HAVE_LRINTF 1' >> config.h
make
make install

13.Create symblinks

ln -s /usr/local/lib/libavformat.so.50 /usr/lib/libavformat.so.50
ln -s /usr/local/lib/libavcodec.so.51 /usr/lib/libavcodec.so.51
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51

14.Compile FFMPEG-PHP

cd /usr/local/src/ffmpeg/ffmpeg-php-0.5.0
phpize
./configure
make
make install

15.Install FFMPEG-PHP (make sure the php.ini path is correct.)

Get correct php.ini path add the extesion ffmpeg.so Usually it is given as extension=ffmpeg.so and the extension_dir=/usr/local/lib/php/extensions/

Make sure that the ffmpeg.so is in /usr/local/lib/php/extensions/

echo 'extension=/usr/local/lib/php/extensions/no-debug-non-zts-20020429/ffmpeg.so'>>
/usr/local/Zend/etc/php.ini

Or the best way is to check the path for extension_dir in php.ini Then locate the file ffmpeg.so. Copy the file ffmpeg.so to extension_dir and add the line

extension=ffmpeg.so

in php.ini

16.Restart Apache to load FFMPEG-PHP

service httpd restart

17.Verify the installation

php -r 'phpinfo();' | grep ffmpeg

If you get a few lines such as

ffmpeg
ffmpeg support (ffmpeg-php) => enabled
ffmpeg-php version => 0.5.0
ffmpeg.allow_persistent => 0 => 0

Then everything is installed and working. FFMPEG, FFMPEG-PHP, MPlayer, MEncoder, flv2tool, LAME MP3 encoder & libOGG.

You can use mod_rewrite for redirecting http to https.
You need to go in the http vhost container and add the following:

========================================

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
Or else, you can add the following lines

RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]

Adding Linux templates in SolusVM(OpenVZ)

Firstly, login to your server node vis SSH.
The download link for the distros : http://wiki.openvz.org/Download/template/precreated

Perform the following :
#cd /vz/template/cache
#wget http://wiki.openvz.org/Download/template/precreated/centos-5-x86-devel.tar.gz (CentOS 5 as an example)

Then, login to SolusVM and "Add new template". This will add the new distro.

Exim4 Error : "Fatal: no entropy gathering module detected"

Exim4 Error : "Fatal: no entropy gathering module detected"
I just want to share with you all the error that I came across regarding exim and here I'm providing the fix for it as well which worked perfectly for me. I tried to send email using 'mail' command which returned me this error message "Fatal: no entropy gathering module detected".

Here is the fix for this that got it working for me!

SSH to your server and perform the following steps :

# cd /dev
Here you can find either URANDOM and/or RANDOM
Delete them.

# rm -rf urandom
# rm -rf random

Now we have to remake both of them and chmod it.
# /sbin/MAKEDEV urandom
# /sbin/MAKEDEV random
# chmod 777 /dev/urandom
# chmod 777 /dev/random

Nagios Configuration

Nagios Configuration
Following steps will take place when Nagios (installed on Nagios server) monitors a service (eg: server load) on the remote host

1) Nagios will execute check_nrpe command on nagios-server and will request it to monitor disk usage on remote host using check_load command.
2) The check_nrpe on the nagios-server will contact the NRPE daemon on remote host and will request it to execute the check_load on remote host.
3) The results of the check_load command will be returned back by NRPE daemon to the check_nrpe on nagios-server.

Nagios Server (check_nrpe) ~~> Remote host (NRPE deamon) ~~> check_load

Nagios Server (check_nrpe) <~~ Remote host (NRPE deamon) <~~ check_load (returns the server load)

Before we begin, we need to install some packages on the remote host for Nagios to work fine.

# yum install elinks gcc make gcc-c++
# yum -y install openssl-devel
# useradd nagios
# passwd nagios
# cd /usr/src/

Then install Nagios plugin and NRPE on remote host.

Install Plug-in
# wget http://sourceforge.net/projects/nagiosplug/files/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz/download
# tar -zxvf nagios-plugins-1.4.15.tar.gz && cd nagios-plugins-1.4.15
# ./configure --with-nagios-user=nagios --with-nagios-group=nagios
# make
# make install
# chown nagios:nagios /usr/local/nagios
# chown -R nagios:nagios /usr/local/nagios/libexec
# cd ..

Install NRPE
#wget http://sourceforge.net/projects/nagios/files/nrpe-2.x/nrpe-2.12/nrpe-2.12.tar.gz/download
# tar -zxvf nrpe-2.12.tar.gz && cd nrpe-2.12
# ./configure
# make all
# make install-plugin
# make install-daemon
# make install-daemon-config
# make install-xinetd
Edit Xinetd NRPE entry
# vi /etc/xinetd.d/nrpe
only_from = 127.0.0.1 Server-IP (nagios monitoring server ip-address is: )
:wq (save and exit)

Edit services file entry
# vi /etc/services
nrpe 5666/tcp # Entry for NRPE daemon
:wq (save and exit)

Restart xinetd
# service xinetd restart

Verify whether NRPE is listening
# netstat -at |grep nrpe # output -: tcp 0 0 *:nrpe *.* LISTEN
Verify to make sure the NRPE is functioning properly
# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.12

Configuring Nagios monitoring server to monitor the remote host

# cd /usr/src
# wget http://sourceforge.net/projects/nagios/files/nrpe-2.x/nrpe-2.12/nrpe-2.12.tar.gz/download
# tar -zxvf nrpe-2.12.tar.gz && cd nrpe-2.12
# yum -y install openssl-devel
# yum install perl
# ./configure
# make all
# make install-plugin

Create a command definition
# vi /home/nagios/public_html/etc/objects/commands.cfg
Add the following:

# NRPE CHECK COMMAND
# Command to use NRPE to check remote host systems
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}

Create configuration file for remote host
# cp –prf /home/nagios/www/etc/objects/ localhost.cfg /home/nagios/www/etc/objects/remotehost.cfg
# vi /home/nagios/www/etc/objects/remotehost.cfg
Replace the values “host_name” “alias” “address” with the values that match your setup:

** The “host_name” you set for the “define_host” section must match the “host_name” in the “define_service” section **

# Define a host for the remote machine
