# Include /private/etc/apache2/extra/httpd-vhosts.conf

Next, you’ll need to setup whatever virtual hosts you have in the virtual hosts file /private/etc/apache2/extra/httpd-vhosts.conf

You need to make an entry in the httpd-vhosts.conf file like so:

<virtualhost *:80>
   ServerName beta-site-1.com
   ServerAlias www.beta-site-1.com
   ServerAdmin webmaster@beta-site-1.com
   ErrorLog "/private/var/log/apache2/dummy-host2.example.com-error_log"
   CustomLog "/private/var/log/apache2/dummy-host2.example.com-access_log" common

   DocumentRoot "/Library/WebServer/beta-site-1"
   ScriptAlias /cgi-bin/ "/Library/WebServer/beta-site-1/cgi-bin"
   
     Options FollowSymLinks MultiViews Includes
     AllowOverride All
     Order allow,deny
     Allow from all
   
</virtualhost>

The examples provided by Apple in the vhosts file are slightly incorrect and if you use the CustomLog lines as is you will get errors the following errors if you run: apachectl -t -D DUMP_VHOSTS:
Syntax error on line 40 of /private/etc/apache2/extra/httpd-vhosts.conf:
CustomLog takes two or three arguments, a file name, a custom log format string or format name, and an optional "env=" clause (see docs)

This is because
CustomLog "/private/var/log/apache2/dummy-host.example.com-access_log common

Should actually read:
CustomLog "/private/var/log/apache2/dummy-host.example.com-access_log" common

However, one thing that changed with Leopard is the socket for Mysql. It moved to /private/tmp, so you may need to configure your php.ini file to point it to the new location.

To do so, open the file /private/etc/php.ini, (if no such file exists, then make a copy of /private/etc/php.ini.default and rename it to php.ini) and edit that.

You have two lines to modify:

mysql.default_socket =

becomes:

mysql.default_socket = /private/tmp/mysql.sock

and mysqli.default_socket =

becomes:

mysqli.default_socket = /private/tmp/mysql.sock

Assuming you want to add the path /usr/local/bin make .profile look like this:
PATH=/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin

Separating each item with a colon.

Under Windows I did the same thing by relocating ‘My Documents’ but it was never very succesful because remnants of your data always remained intermingled with the system. Having moved to OS X I found the default installation was to dump everything on one partition. OS X is a superior system and doesn’t suffer as badly , but you are still inconvenienced if you want to reformat and start afresh.

I did read several articles on the net about keeping your user data seperate, but all were complicated. I have developed a method that is very safe and easy to do. You will need to use the Terminal application to type several commands.

The easiest way to go about this is to wait until you are ready to reformat again. Make sure you BACKUP ALL YOUR DATA ON TO AN EXERNAL DRIVE. Restart with the installation disc. Once it starts up go to Utilities and choose Disk Utility. From the left pane select your internal hard drive in my case “74.5GB ST98823AS” and now you can choose the “Partition” tab. Under “volume scheme” choose a 2 partition layout. It will now show your disc split in two at about half way, drag the slider up/down so that you end up giving about 20GB to the top part. This is where your system and applications will be installed. Name the paritions if you so wish and apply changes. Then continue the installation as normal.

When you boot in to your new system start up the Terminal application. What follows next are some commands for you to type in to the terminal. These will be run as a super-user (hence sudo) and will require you to enter your password to execute properly. Ensure you get these commands correct as you will regret doing a rush-job here. Firstly, you should remember how you named your partitions, if you can’t remember then have a look in Finder. Or even better: type the following in the terminal:

ls /Volumes

I will refer to the paritions as “system” and “userpart”, replace these with the correct names of your partitions. Now, move your user folders off the system partition on to userpart:

sudo mv /Volumes/system/Users/ /Volumes/userpart/

Then move the old “Users” folder out of the way, and create a link back to it:

sudo mv /Users /Users.bk
sudo ln -s /Volumes/userpart/Users /Users

What you have done is to move the Users directory on to another partition and then create a softlink back to it. This means that all applications and OS X will still continue to use /Users on the system drive, but that just points to the user drive. The advantage is you don’t need to perform any special configuration to inform OS X or your applications of the change, they are unware of any change.

If you have any problems don’t blame me!
