add apache to users group

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

Protect .svn directories server-wide (Apache)

// protect ".svn" and "CVS" dirs (could add more)

Setup LAMP on Ubuntu with MyODBC support.

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

Driver       = /usr/lib/odbc/
Description  = MyODBC 3.51 Driver DSN
SERVER       =
PORT         =
USER         = USER
Password     = XXXXXX
Database     = DBNAME
OPTION       = 3
SOCKET       =

Driver       = /usr/local/lib/
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

Run Apache in 32bit mode on Leopard

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

Apache rewrite rules

Pass all requests for non-existing files or directories to index.php
RewriteCond        %{REQUEST_FILENAME}        !-f                
RewriteCond        %{REQUEST_FILENAME}        !-d
RewriteRule        ^(.*)$                    index.php        [L]

Maintenance mode for apache

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
ErrorDocument 403
Order deny,allow
Deny from all
Allow from

Latest file to download

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: ""

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

restart Apache process

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

Apache - IfModule dir_module directive within httpd-vhosts.conf

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

This can be placed directly within the VirtualHost directives.

<IfModule dir_module>
  DirectoryIndex index.html index.php

Force traffic to use SSL (HTTPS://)

// Forces incoming traffic to use SSL connection

 #Force SSL
 RewriteCond %{SERVER_PORT} !443
 RewriteRule ^(.*)$$1 [R=301,L]

Serve php within .htm

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

301 Permanent Redirect rule to consolidate domains

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

RewriteEngine On
RewriteCond %{HTTP_HOST} ^$ [NC]
RewriteRule ^(.*)$$1 [R=301,L]

.htaccess in home or other directory

Rolling Apache Logfiles

This is a little snippet I whipped up long ago to roll our logs, feel free to use...


/usr/bin/grep CustomLog /usr/local/etc/apache2/httpd.conf |/usr/bin/grep -v \#|/usr/bin/awk '{print $2}'|/usr/bin/sort|/usr/bin/uniq|/usr/bin/grep -v /var/log > logfiles
/usr/bin/grep ErrorLog /usr/local/etc/apache2/httpd.conf |/usr/bin/grep -v \#|/usr/bin/awk '{print $2}'|/usr/bin/sort|/usr/bin/uniq|/usr/bin/grep -v /var/log >> logfiles
/usr/local/bin/ --loglist logfiles --touchlog --restart_cmd "/usr/local/etc/rc.d/ restart" --compress --days 120

The is a script from Uthe Urchin folk, available at

PHP on mod_fcgid with Apache2 and mod_suexec

This took a little doing and some major tweaking. Assuming you have the LoadModule line already...

  AddHandler fcgid-script .php

  <Directory /home/elitesys/>
    FCGIWrapper /home/elitesys/ .php

  IPCConnectTimeout 20
  IPCCommTimeout 300

Add the handler for php files, specify the wrapper (in this case the file in the root of the site) and setup connect and communication timeouts. The timeouts are in seconds and you need to set it like that or higher or else file uploads will timeout and I have heard of issues with Wordpress if you don't increase it.

And in php.fcgi...
export PHPRC
exec /usr/php4/bin/php

This should look familiar to another post...

There isn't a definition for suexec in terms of executable location. There doesn't have to be. Apache will automatically wrap it properly. This configuration is far easier than mod_fastcgi and works just as well. Probably easily expanded to work with ruby on rails although I havn't tried yet...
