If php-apache relationship is CGI, then php.ini file is used to disable safe_mode value

 If none of the above works, contact your hosting provider and ask them to disable safe_mode through the servers httpd.conf file. It can be done in your VirtualHost configuration inside httpd.conf file.

.htaccess Code

php_admin_value safe_mode Off [OR]
php_flag safe_mode Off

edit php.ini ( use this command to find php.ini file location – “php -i | grep php.in” ) 

safe_mode = Off

edit httpd.cof 

php_admin_value safe_mode Off

Verify your settings

 Create phpinfo page file  and put it on the document root and access the page to see if the defult value has been overrided with your defult value.

phpinfo sample. 

example 
vi  phpinfo.php

<?php
phpinfo();
?>

You may use register_globals keyword instead of safe_mode to change values of register_globals variable [off/on values are accepted]

Installing PHP eAccelerator from source

Requirements

     * php4 or php5
    * autoconf
    * automake
    * libtool
    * m4 

eAccelerator only works with mod_php or php in fastcgi mode. It can’t be used in cgi or cli because eAccelerator needs to set up shared memory, and this can only be done when all php instances that need to access it are forks of the first process.

Installation
download  eAccelerator

Download the tarball file from the source  

cd /usr/local/src/
mkdir eacp
cd eacp
wget http://bart.eaccelerator.net/source/0.9.5.2/eaccelerator-0.9.5.2.tar.bz2
bunzip2 eaccelerator-0.9.5.2.tar.bz2
tar xvf eaccelerator-0.9.5.2.tar
cd eaccelerator-0.9.5.2 

 Compiling eAccelerator 

When you have more then one php install or the phpize and php-config scripts aren’t in your path then you should follow this procedure
This example has php installed in /usr/bin/php (command to know the path – which php), this is the path of the –prefix option given to the php configuration script.

export PHP_PREFIX=”/usr/”
$PHP_PREFIX/bin/phpize

./configure –enable-eaccelerator=shared –with-php-config=$PHP_PREFIX/bin/php-config –with-eaccelerator-info

make
make install

copy the all php files under the eaccelerator-0.9.5.2 directory to the document root of server

cp *.php /usr/local/apache/htdocs/eacp

Configuring eAccelerator

eAccelerator can be installed both as Zend or PHP extension. When you install eAccelerator as a zend_extension you need to give the full path to the eaccelerator.so library.

To install as Zend extension: Add the follwing lines below the zend entries in the php.in file

/scripts/restartsrv_httpd

 Verify if eAccelerator works

php -v 

eaccelerator.allowed_admin_path=”/usr/local/apache/htdocs/eacp”
zend_extension=”/usr/local/lib/php/extensions/no-debug-non-zts-20020429/eaccelerator.so”
eaccelerator.shm_size=”16″
eaccelerator.cache_dir=”/tmp/eaccelerator”
eaccelerator.enable=”1″
eaccelerator.optimizer=”1″
eaccelerator.check_mtime=”1″
eaccelerator.debug=”0″
eaccelerator.filter=”"
eaccelerator.shm_max=”0″
eaccelerator.shm_ttl=”0″
eaccelerator.shm_prune_period=”0″
eaccelerator.shm_only=”0″
eaccelerator.compress=”1″
eaccelerator.compress_level=”9″

restart the httpd

/scripts/restartsrv_httpd

Verify if eAccelerator works 

php -v 

When eAccelerator is loaded successfully you will see something like:

    with eAccelerator v0.9.5-beta2, Copyright (c) 2004-2006 eAccelerator, by eAccelerator
————————————————————————————————
or check with phpinfo page

Using Web contrlol panel of eAccelerator

browse the pages under the default document root

http://default.domain.com/eacp/control.php

Finished

Please follow the steps to install APC mem Cache

1. cd /usr/local/src
2. wget http://pecl.php.net/get/APC-3.0.14.tgz
3. tar -xzvf APC-3.0.14.tgz
4. cd APC-3.0.14

 
 checking  the location of phpize and php-config paths

finding the  Phpize binary location

whereis phpize

output looks like:

phpize: /usr/bin/phpize /usr/local/bin/phpize

whereis php-config

output looks like:

php-config: /usr/bin/php-config /usr/local/bin/php-config

5. execute the command to create the module

/usr/bin/phpize  ( or the path you got )

6.  compile  the APC by running following command 

   ./configure –enable-apc –enable-apc-mmap –with-apxs=/usr/local/apache/bin/apxs    –with-php-config=/usr/bin/php-config
  make
 make test
 make install

Take note of where it copies apc.so file i.e.

/usr/lib/php/extensions/no-debug-non-zts-20020429/apc.so

10. Now locate php.ini type:

     php -i | grep php.ini

11. Edit php.ini

 Add these entries in the dynamic module section ( please note the extention path can be varied ) 

extension=”/usr/lib/php/extensions/no-debug-non-zts-20020429/apc.so”
apc.shm_size = 32

restart webserver . Check the php info page you can see the apc module listed .

 1. Create a directory to do our work 

mkdir ~/ffmpeg
cd ~/ffmpeg

2. Get all the source files

wget http://www3.mplayerhq.hu/MPlayer/releases/codecs/essential-20061022.tar.bz2
wget http://rubyforge.org/frs/download.php/9225/flvtool2_1.0.5_rc6.tgz
wget http://easynews.dl.sourceforge.net/sourceforge/lame/lame-3.97.tar.gz

4. Create the codecs directory & import them

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

5. Install SVN/Ruby (Depends on OS, this is for RHEL/CentOS)

yum install subversion
yum install ruby
yum install ncurses-devel

6. Get the latest FFMPEG/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 ~/ffmpeg/lame-3.97
./configure
make

14. Compile FFMPEG-PHP

cd ~/ffmpeg/ffmpeg-php-0.5.0
phpize
./configure
make
make install

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

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

16. Restart Apache to load FFMPEG-PHP (Depends on OS, this is for RHEL/CentOS)

service httpd restart

17. Verify if it works

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.
