This is ideal for web servers to avoid running MTA daemons like sendmail, Exim and Postfix which use up resources on the server.

1. Install sSMTP (Note: Any previously installed MTA will be removed)

apt-get install ssmtp


2. Configure the server (pico /etc/ssmtp/ssmtp.conf)

mailhub=mail.example.org
FromLineOverride=YES


Replace mail.example.org with the external mail server that you want to relay all mail to.

If you would like to relay through Google Mail servers, change these configuration values:

mailhub=smtp.gmail.com:587
UseSTARTTLS=Yes
AuthUser={username}
AuthPass={password}
FromLineOverride=YES


Replace {username} with your Gmail username and {password} with your Gmail password.

That's all! sSMTP doesn't run as service so there's no restart required. sSMTP creates a link to /usr/sbin/sendmail which most programs use by default to send mail including PHP.

1. Install Apache2 and PHP5 (as an Apache module)

apt-get install apache2 php5 libapache2-mod-php5 php5-mysql


2. Install MySql server

apt-get install mysql-server


3. At this point you may need to restart Apache

/etc/init.d/apache2 restart


3. Create a test php file

echo "<?php phpinfo(); ?>" > /var/www/info.php


The default document root for Debian is in /var/www so you can access the test file on this location: http://yourserver/info.php

3. Install phpMyAdmin (optional but preferred by most developers and administrators)

apt-get install phpmyadmin


By default, phpmyadmin will be accessible on: http://yourserver/phpmyadmin

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.

1. Download the eAccelerator source. The latest version is mirrored on www.debiantutorials.com as it's not available on the official site anymore.

cd /tmp
wget http://www.debiantutorials.com/static/eaccelerator-0.9.6.1.tar.bz2


2. Extract

tar -xvjf eaccelerator-0.9.6.1.tar.bz2


3. Install php5-dev

apt-get install php5-dev


3. Compile and install the eAccelerator

phpize
./configure
make
make install


4. Configure eAccelerator as PHP extension (create a new config file: pico /etc/php5/conf.d/eaccelerator.ini)

extension="eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/var/cache/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"


5. Create a cache directory

mkdir -p /var/cache/eaccelerator
chmod 0777 /var/cache/eaccelerator


5. Restart apache

/etc/init.d/apache2 restart


1. Install the apache2-mpm-itk package

apt-get install apache2-mpm-itk


2. Configure user and group for each virtual host by adding the following line somewhere between <VirtualHost *:80>...</VirtualHost>

AssignUserId [user] [group]


Replace [user] and [group] with a username and group name that already exists on the system.

3. Change the owner of the web root

chown [user].[group] [location]


Replace [user] and [group] with the username and group name configured on the virtual host. Replace [location] with the location specified as DocumentRoot for the virtual host, eg. /var/www

4. Make sure the location isn't accessible by other users (optional)

chmod o= [location]


Replace [location] with the location specified as DocumentRoot for the virtual host, eg. /var/www

5. Restart apache

/etc/init.d/apache restart


1. Add these lines to the apt sources (pico /etc/apt/sources.list)

deb http://php53.dotdeb.org stable all
deb-src http://php53.dotdeb.org stable all


2. Download and import the dotdeb key

wget http://www.dotdeb.org/dotdeb.gpg
cat dotdeb.gpg | sudo apt-key add -


3. Update apt and dist-upgrade

apt-get update
apt-get dist-upgrade


1. Install Apache2, MySql server and PHP5 with required modules. You may already have some or all of these packages installed.

apt-get install apache2 php5-cli php5 mysql-server libdbd-mysql-perl php5-gd php5-mysql libapache2-mod-php5


2. Download the latest version of MailWatch

wget http://downloads.sourceforge.net/project/mailwatch/mailwatch/1.0.5/mailwatch-1.0.5.tar.gz


At the time this tutorial was written, version 1.0.5 was the latest version. Check this location for latest version: http://sourceforge.net/projects/mailwatch/files/

3. Extract and enter the mailwatch directory

tar zxvf mailwatch-1.0.5.tar.gz
cd mailwatch-1.0.5


4. Create the database and tables

mysql -p < create.sql


5. Create a MySql user used for MailScanner logging (mysql -u root -p)

GRANT ALL ON mailscanner.* TO '{username}'@'localhost' IDENTIFIED BY '{password}';
FLUSH PRIVILEGES;


Replace {username} and {password} with a username and password of choice.

6. Configure the MailScanner logger (pico MailWatch.pm)

my($db_user) = '{username}';
my($db_pass) = '{password}';


On line 43 and 44, input your MySql user created in step 5

7. Move the MailScanner logger to correct directory

mv MailWatch.pm /usr/share/MailScanner/MailScanner/CustomFunctions/


8. Edit Mail Scanner config to enable MailWatch logger (pico /etc/MailScanner/MailScanner.conf)

Always Looked Up Last = &MailWatchLogging


9. Create a MailWatch web admin user (mysql -u root -p)

USE mailscanner;
INSERT INTO users VALUES ('{username}',md5('{password}'),'Administrator name','A','0','0','0','0','0');


Replace {username} and {password} with a username and password used to enter the web interface.

10. Move the web interface to the web server's root

mv mailscanner /var/www/mailwatch


11. Make the temp and cache directories writeable

chmod 777 /var/www/mailwatch/temp
chmod 777 /var/www/mailwatch/images/cache


12. Copy the example config file

mv /var/www/mailwatch/conf.php.example /var/www/mailwatch/conf.php


13. Configure the web interface (pico /var/www/mailwatch/conf.php)

define('DB_USER', '{username}');
define('DB_PASS', '{password}');
define('MAILWATCH_HOME', '/var/www/mailscanner');


Type the MySql username and password created in step 5

14. Install PEAR PHP framework

apt-get install php-pear


15. Install required PEAR packages

pear install DB
pear install DB_Pager
pear install Mail_mimeDecode


16. On line 37, add /usr/share/php to the mailwatch include path (pico /var/www/mailwatch/functions.php)

ini_set('include_path','.:'.MAILWATCH_HOME.'/pear:'.MAILWATCH_HOME.'/fpdf:'.MAILWATCH_HOME.'/xmlrpc:/usr/share/php');


17. Restart Apache and MailScanner

/etc/init.d/apache2 restart
/etc/init.d/mailscanner restart


18. You're all set. Enter the web interface at this location http://yourserver/mailwatch

1. Install the PEAR framework

get install php-pear


2. Restart apache

/etc/init.d/apace2 restart


3. Install a PEAR package (optional)

pear install Net_Ping-2.4.5


You can install any PEAR package using this command but in this example we'll install the Net_Ping package

4. Here's a sample PHP code to use the Net_Ping package (optional)

require_once "Net/Ping.php";
$ping = Net_Ping::factory();
 
$host = 'debiantutorials.com';
$count = 3;
 
if (PEAR::isError($ping))
{
    echo $ping->getMessage();
}
else
{
    $ping->setArgs(array('count' => $count));
    $res = $ping->ping($host);
    foreach ($res->_raw_data as $line)
    {
        echo $line . "\n";
    }
}


This code will ping the host debiantutorials.com three times and echo the results

1. Installing the XCache package

apt-get install php5-xcache


2. Restart Apache

/etc/init.d/apache2 restart


That's it. XCache is now installed.

1. Download a copy of Zend Optimizer / Guard from the location below and put it into /tmp

http://www.zend.com/en/products/guard/downloads


2. Extract

cd /tmp
tar zxvf ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz


Replace with your actual filename

3. Create a directory to contain Zend optimizer

3. Move the Zend optimizer lib to a permanent location

mv ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp/ZendOptimizer.so /usr/local/lib/Zend/


Your ZendOptimizer directory name may be different since it includes version numbers and platform. I'm using the 5_2_x_comp directory because I have PHP 5.2 installed.

4. Add reference to your php.ini file (pico /etc/php5/apache2/php.ini)

zend_extension = /usr/local/lib/Zend/ZendOptimizer.so
zend_optimizer.optimization_level = 15


5. Restart apache

/etc/init.d/apache2 restart
