Change the sudoers list by adding a NOPASSWD: [Cmnd_Alias] line.

In terminal: visudo

# Cmnd alias specification
Cmnd_Alias HTTPD = /usr/local/sbin/apachectl, /etc/init.d/apache2

# User privilege specification
[user] ALL = NOPASSWD: HTTPD

// this handy one liner is used on any new webserver..
// puts apache into the users group to allow dev teams etc..

sed -i 's/users:x:1000:admin/users:x:1000:admin,wwwrun/' /etc/group

// block access to .svn dirs
// should be done server-wide if you can (another snippet)

<IfModule mod_rewrite.c>
  RewriteRule ^(.*/)?\.svn/ - [F,L]
  ErrorDocument 403 "Access Forbidden"
IfModule>

// protect ".svn" and "CVS" dirs (could add more)
// for server-wide protection; goes in httpd.conf
// there's a separate snippet for .htaccess-based code

<DirectoryMatch "^/.*/(\.svn|CVS)/">
  Order deny,allow
  Deny from all

Go to terminal:

sudo apt-get install apache2 mysql-server php5 php5-odbc libapache2-mod-php5 php5-xsl php5-gd php-pear libapache2-mod-auth-mysql php5-mysql libmyodbc

Now hand edit (or create, if it does not exist already) /etc/odbc.ini

Here's an example odbc.ini:

[ODBC Data Sources]
odbcname     = MyODBC 3.51 Driver DSN

[odbcname]
Driver       = /usr/lib/odbc/libmyodbc.so
Description  = MyODBC 3.51 Driver DSN
SERVER       = my.database.server.com
PORT         =
USER         = USER
Password     = XXXXXX
Database     = DBNAME
OPTION       = 3
SOCKET       =

[Default]
Driver       = /usr/local/lib/libmyodbc3.so
Description  = MyODBC 3.51 Driver DSN
SERVER       = localhost
PORT         =
USER         = root
Password     =
Database     = test
OPTION       = 3
SOCKET       =

Remember to start and stop mysql and apache:

sudo /etc/init.d/mysql start
sudo /etc/init.d/apache2 start

sudo /etc/init.d/mysql stop
sudo /etc/init.d/apache2 stop
sudo /etc/init.d/mysql restart
sudo /etc/init.d/apache2 restart

There is currently an issue resulting from the fact that Apache on Mac OS X 10.5 is built as a 64 bit application. On Macs that support 64 bits (all current Mac models), Apache will run in 64 bit mode. This is incompatible with most ODBC drivers, including those currently available from Actual Technologies.
Until we can make 64 bit versions of our drivers available, we recommend a workaround to force Apache to run in 32 bit mode. Using the Terminal prompt, enter the following commands (this is for ppc machines, for intel switch ppc7400 to i386):

sudo mv /usr/sbin/httpd /usr/sbin/httpd.ub

sudo lipo -thin ppc7400 /usr/sbin/httpd.ub -output /usr/sbin/httpd.ppc7400

sudo ln -s /usr/sbin/httpd.ppc7400 /usr/sbin/httpd 

Now restart Web Sharing in the System Preferences, and continue with the instructions for "Invoking ODBC Functions from ODBC" below.
NOTE: if you ever need to restore Apache to 64 bit mode, just enter the following command:

sudo mv /usr/sbin/httpd.ub /usr/sbin/httpd

Pass all requests for non-existing files or directories to index.php

RewriteCond        %{REQUEST_FILENAME}        !-f                
RewriteCond        %{REQUEST_FILENAME}        !-d
RewriteRule        ^(.*)$                    index.php        [L]

Doing some work on your web site but you don't want other people to see what you're doing. Give them a redirect (like the flickr massage screen).
You need to use your own ip of course.

# redirect all visitors to alternate site but retain full access for you

Order deny,allow
Deny from all

Perl script using shell command to get(/grep) the lastest file on directory for download.

Just Create .htaccess (DirectoryIndex .latest.cgi) for more automations, so to get the latest files, just point your download link to: "yoursite.com/files/"

#!/usr/bin/perl
#This is .latest.cgi
$|++; my @file = `ls -1 -t -p | grep -v -P '/'`; 
print "Location: $file[0]\n\n";
exit;

To reload conf files

To verify changes to .conf files parse OK.

apachectl -t

To issue soft restart (waits for connections to close)

apachectl graceful

Forced restart, dropping connections as necessary.

apachectl restart

Change directory listing / default files served when hitting a directory.

This can be placed directly within the VirtualHost directives.

 RewriteRule ^(.*)$ https://securesiteurl.com/$1 [R=301,L]

In your .htaccess file (maybe only in a specific folder) add this line to parse a .htm as a php file. This works on TxD accounts.

AddType application/x-httpd-php .htm .php

// redirect domain.com to www.domain.com (or vice versa)
// helps substantially with delicious links and other SEO optimization
// see for discussion

RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]
