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]

Installation

Please follow the steps to install imagemagick

download latest version from source

ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz

unpack the source

tar  zxvf  ImageMagick.tar.gz

Next configure and compile ImageMagick:

cd ImageMagick.6.?.?

./configure

make

Installing

make install

PerlMagick is an objected-oriented Perl interface to ImageMagick. Use the module to read, manipulate, or write an image or image sequence from within a Perl script. This makes it very suitable for Web CGI scripts. You must have ImageMagick 6.2.0 or above and Perl version 5.005_02 or greater installed on your system for either of these utilities to work.

cd PerlMagick

perl Makefile.PL
make
make install

 

verify your installation

Congratulations, now your ready to go..............

  

Required packages

Apache
OpenSSL
j2sdk
jakarta-tomcat
jakarta-ant
jakarta-tomcat-connectors(mod_jk)

Configure Environment Variables

Edit and add the lines below to “/etc/profile”

JAVA_HOME=/usr/local/java/java
CATALINA_HOME=/usr/local/tomcat
PATH=$JAVA_HOME/bin:$PATH:$HOME/bin:/sbin:/usr/sbin
CLASSPATH=$CATALINA_HOME/bin/bootstrap.jar:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/common/lib/servlet.jar:/usr/local/pgsql/share/java/postgresql.jar:../lib/struts.jar:.

Now add the PATH JAVA_HOME CATALINA_HOME & CLASSPATH if any aren’t in the export line

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC JAVA_HOME CATALINA_HOME CLASSPATH

Install Java

mkdir /usr/local/java
cd /usr/local/java
sh jdk-1_5_0_04-linux-i586.bin

The jdk directory is then extracted

mv jdk-1_5_0_04 /usr/local/java
ln -s jdk-1_5_0_04 java

Now the java directory will be in /usr/local/java/java. I do it like this so I can keep all my different JDKs/JREs in one directory and then just change the symbolic link to point to the current one.

Install Jakarta TOMCAT (Tomcat4 or Tomcat5 can be used)

tar xvfz jakarta-tomcat-4.1.29.tar.gz
mv jakarta-tomcat-4.1.29 /usr/local/
cd /usr/local
ln -s jakarta-tomcat-4.1.29 tomcat

Install Jakarta ANT

tar xvfz jakarta-ant-1.6.0

cd /usr/local
ln -s jakarta-ant-1.6.0 ant
ln -s /usr/local/ant/bin/ant /usr/local/bin/ant

Install OPENSSL

tar xvfz openssl-0.9.7d.tar.gz
mv openssl-0.9.7d /usr/local/src/
cd /usr/local/src/openssl-0.9.7d
./config
make
make test
make install
#This will install in /usr/local/ssl

Install APACHE

tar xvfz httpd-2.0.48.tar.Z
cd httpd-2.0.48
./configure –prefix=/usr/local/apache2 –enable-so –enable-rewrite \
                –enable-ssl –with-ssl=/usr/local/ssl –enable-proxy
make
make install   
#(places in /usr/local/apache2)

Build/Install MOD_JK Connector

cd /usr/local/src/jakarta-tomcat-connectors-jk-1.2.5-src/jk/native
./buildconf.sh
./configure –with-apxs=/usr/local/apache2/bin/apxs
make
cp apache-2.0/mod_jk.so /usr/local/apache2/modules   

Configure Apache for mod_jk

I put these lines in http.conf just before NameVirtualHost

<IfModule !mod_jk.c>
  LoadModule jk_module modules/mod_jk.so
</IfModule>

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:
————————————————————————————————

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 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 .

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

Please follow the steps to install SSL certificate on Apache

# cd /usr/local/apache

# mkdir cert
# cd cert

1. Generate your own Certificate Authority (CA)

# openssl genrsa -out ca.key 4096
# openssl req -new -x509 -days 365 -key ca.key -out ca.crt

2.Generate a server key and request for signing (csr)

# openssl genrsa -out server.key 4096
# openssl req -new -key server.key -out server.csr

3.Sign the certificate signing request (csr) with the self-created certificate authority (CA) that you made earlier

# openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt

Edit /usr/local/apache/conf/httpd.conf

ServerName xxx.xxx.xxx.xxx:443
Listen xxx.xxx.xxx.xxx:443
LoadModule ssl_module modules/mod_ssl.so

SSLEngine on
SSLCertificateFile /usr/local/apache/cert/server.crt
SSLCertificateKeyFile /usr/local/apache/cert/server.key

# /usr/local/apache/bin/apachectl restart

To do the same with a Passphrase follow below

# cd /usr/local/apache
# mkdir cert
# cd cert
# openssl genrsa -des3 -out ca.key 4096
# openssl req -new -x509 -days 365 -key ca.key -out ca.crt
# openssl genrsa -des3 -out server.key 4096
# openssl req -new -key server.key -out server.csr
# openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt

Rest of the configuration remains same

2.Extract it to the Squirrelmail – plugins directory

cd /var/www/html/squirrelmail/plugins

# tar xzf compatibility-2.0.9-1.0.tar.gz
# cd compatibility

3.Patch it to your squirrelmail version

# patch -p0 < patches/compatibility_patch-1.4.11.diff
patching file ../../functions/strings.php

4.Configure the Squirrelmail to include the plugin

# cd ../../config
# ./conf.pl

5.Extract Local Auto Responder Plugin

# cd ../plugins/
# tar xzf local_autorespond_forward-3.0-1.4.0.tar.gz
# cd local_autorespond_forward

6.Compile suid_backend module

# cd suid_backend/
# ./configure –enable-webuser=nobody

Here my Apache is running as user “nobody”.That user should have the permission to play
with the directories under this.

# make
# make install

7.Copy the sample config.php

# cd ..
# cp config.sample.php config.php

8.Edit the config.php to use “suid” instead of “ftp” for Maildir and “.forward” files

edit config.php

$laf_backend = ’suid’;

9.Configure the Squirrelmail to include the plugin

# cd ../../config
# ./conf.pl

10.Verify the Squirrelmail’s ATTACHMENT DIR and DATA DIR. Verify the permission also

edit /var/www/html/squirrelmail/config/config.php

$attachment_dir = ‘/var/local/squirrelmail/attach/’;

11.Create it if doesn’t exist

# mkdir /var/local/squirrelmail/attach
# chown nobody.nobody /var/local/squirrelmail/attach
# chmod 755 /var/local/squirrelmail/attach

Finish…… you can go now…

Thanks,

Linux buddy

If you are on an RPM installation of Apache you will find the apache configuration file probably here:

/etc/httpd/conf/httpd.conf

If you are using apache from the source tar balls probably you will find the configuration file here:

/usr/local/apache/conf/httpd.conf

Edit the httpd.conf file and scroll until you find a line like this:

Options All Indexes FollowSymLinks MultiViews

To disable directory browsing carefully remove the line that says: Indexes and leave the line like this:

Options All FollowSymLinks MultiViews

Restart your apache webserver and thats it
