The following instructions are mostly the same as before – except it’s not quite so easy now – if you want more than a base PHP install that is. (I even had another look at the commercial MAMP Pro offering. Nah.) For a simple MAMP stack you really only need to turn on Apple’s PHP package and grab a copy of MySQL. If easy is good for you – jump to 1.5.

But I “like” to have phpMyAdmin and don’t like being warned that I’m missing the mcrypt extension for PHP. If you want mcrypt too – start at #1.

Tools & Requirements:

• You need admin access on your Mac
• Basic understanding of the filesystem and Terminal.app
• If you’ve not got it already grab the wonderful and free editor TextWrangler. The config files that need editing are hidden from normal view- but easily reached by TextWrangler which even has a menu item for that: File / Open hidden… .  It also handles authentication beautifully to allow saving without having to manually change permissions to and fro.

1. [extra steps to customise things first eg add mcrypt PHP extension - if you don't need/want it skip past to 1.5.] Go and see Xeon Xai’s blog post Snow Leopard PHP Extensions Installation Tutorial or for a quicker version – go here. These first optional steps to customising your set up (adding PHP extensions and even downgrading PHP from 5.3. to 5.2) has turned out to be more “intereseting” than originally percieved and needs post of its own…

1.5 Prepare your php.ini file by duplicating the supplied stock example file and givining it the right name: In Terminal paste this:

sudo cp /private/etc/php.ini.default /private/etc/php.ini

You’ll need to edit the timezone – replace

;date.timezone = with
date.timezone = Europe/Madrid

For other timezones look to the official list here (note the lost semi colon – that’s the comment character)

1.6 Get PHP looking in the right place for MySQL (once you’ve installed it.) …Still editing php.ini find and replace all instances of /var/mysql/mysql.sock with /tmp/mysql.sock . (Why? – well as documented here it seems php.ini is configured for Mac OS X Server’s bundled version of MySQL)

1.7 Start PHP by un-commenting the LoadModule php5_module line in your /etc/apache2/http.conf file.

1.8 Turn Web Sharing (in System Preferences/Sharing) off-and-on again.

2. Get yourself virtualhost.sh from Patrick Gibson. This little shell script will make the process of setting up proper virtual domains on your development server a cinch. I use “.dev” or “.live” as the TLD to prevent any conflict with the live sites. (Although now I’ve started using Git I may just drop the separation between live and development branch domains on my development box. I still put all my sites in my ~/Sites folder though.

3. MySQL
3.1 If you’ve already got another version installed uninstal MySQL from your Mac. NB – this will delete your databases too! But you’ve got those backed up and you want a clean slate:

• sudo rm /usr/local/mysql
• sudo rm -rf /usr/local/mysql*
• sudo rm -rf /Library/StartupItems/MySQLCOM
• sudo rm -rf /Library/PreferencePanes/My*
• edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
• sudo rm -rf /Library/Receipts/mysql*
• sudo rm -rf /Library/Receipts/MySQL*

3.2 Get a MySQL Community Server for the Mac and install it.

4. Give your MySQL root user a password; type the following into the Terminal:
/usr/local/mysql/bin/mysqladmin -u root password sniggle
…if you like sniggle as a passowrd that is.

5. Now you can administer your MySQL server with phpMyAdmin and the root user you’ve just defined. (There are other tools too – eg MySQL Administrator – but I’m used to phpMyAdmin from the hosting packeges I use). You may want to virtualhost phpMyAdmin to, for example, “http://mysql/”. Love virtualhost.sh.

6. Then for each [dynamic] site you’ll probably want to add a user and then associate a DB with that user. Do this in phpMyAdmin in one step using the Privileges pane fill in “Add a new User”/then select “Create database with same name and grant all privileges”. Job’s a good ‘un.

Done and not long-winded at-all at-all!

Want to get MAMP on Mac OS X 10.6?

If you’re on 10.5 you may read on…

Want to roll a MAMP stack of your own to enable proper local web development? Try these steps to getting you own development environment:

1. Swap the Apple package of PHP for Marc Liyanage’s package of PHP for Mac OS X. Read his notes – only takes a minute. His version has useful “extras” like the mcrypt extension that Apple doesn’t include: you’ll want that for phpMyAdmin. (If you’ve already started Apple’s version – you’ll know how to stop it by re-commenting the LoadModule php5_module line in your http.conf file )

2. Get yourself virtualhost.sh from Patrick Gibson. This little shell script will make the process of setting up proper virtual domains on your development server a cinch. I use “.dev” or “.live” as the TLD to prevent any conflict with the live sites. (Although now I’ve started using Git I may just drop the separation between live and development branch domains on my development box. I still put all my sites in my ~/Sites folder though.

3. Get a Mac OS X MySQL package – (not the latest build but v5.0.x) from the good folks at MySQL. If you’ve already got another version installed – here’s how to uninstal MySQL from a Mac (NB – this will delete your databases too!).

4. Give your MySQL root user a password; type the following into the Terminal:
/usr/local/mysql/bin/mysqladmin -u root password sniggle
…if you like sniggle as a passowrd that is.

5. Now you can administer your MySQL server with phpMyAdmin and the root user you’ve just defined.  (There are other tools too – eg MySQL Administrator – but I’m used to phpMyAdmin from the hosting packeges I use). You may want to virtualhost phpMyAdmin to, for example, “http://mysql/”. Love virtualhost.sh.

6. Then for each [dynamic] site you’ll probably want to add a user and then associate a DB with that user. Do this in phpMyAdmin in one step using the Privileges pane fill in “Add a new User”/then select “Create database with same name and grant all privileges”. Job’s a good ‘un.

Done and not long-winded at-all at-all!

Mmm, me too. I’d have pulled my hair out if I had any. Made me feel rather defeated after thinking I’d fixed things so that one DB connect call would work on two+ servers. Fancy that – PHP behaving unpredictably – anybody would think I was playingworking very hard with CSS.

[
I had finally got round to using substr to trim the public_htmlpart off a DocumentRoot path to get me an absolutely relative link to a safe place...
ie  (substr($_SERVER['DOCUMENT_ROOT'], 0, -12). )
ie keeping the DB connect information out of the public view
]

Anyway for how to fix the trailing slash problem you should point your google at the New Zealand PHP advocates or crib directly from here:

$_SERVER['DOCUMENT_ROOT'] .=
(substr($_SERVER['DOCUMENT_ROOT'],-1)=='/')?'':'/';

Or How to setup a MAMP Stack on… Mac OS X: a proper write up.

Please disregard the gubbins on this post…

[OK - this was going to be a simple step-by-step account of how to install a particular project management system on a Mac OS X box. That particular project stalled but I learnt a few things about how to get a [M]AMP stack setup to the point a which I can continue… ]

Need a project management package. So far requirements and research lead to Open Goo.

• Download package from OpenGoo.
• Create a MySQL database for it.
  • Download and instal PHP My Admin. Nice documentation.
  • • [unstuff it and put the folder into ~/Sites/ , for example]
    • virtualhost it
    • setup config.inc.php with blowfish key
  • fix socket error (?)
    • http://dev.mysql.com/doc/refman/5.0/en/mac-os-x-installation.html: edit (with TextWrangler of course) /etc/php.ini so that  ”mysql.default_socket = /tmp/mysql.sock”
  • Fix mcrypt error: “Cannot load mcrypt extension. Please check your PHP configuration”
  • Ditch the default OS X PHP install in favour of Marc Liyanage’s packaged instal of PHP for Mac OS X
    • If already set up the Apple version of PHP – make sure it’s disabled:  ”LoadModule php5_module“  in /private/etc/apache2/httpd.conf shoul commented out
    • Download and run Marc’s installer from the link above. RTFM mind – but it’s a cinch. The new PHP files will now be in /usr/local/php5.
    • Also ditch any previously installed MySQL
      • sudo rm /usr/local/mysql
      • sudo rm -rf /usr/local/mysql*
      • sudo rm -rf /Library/StartupItems/MySQLCOM
      • sudo rm -rf /Library/PreferencePanes/My*
      • edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
      • sudo rm -rf /Library/Receipts/mysql*
      • sudo rm -rf /Library/Receipts/MySQL*
  • install to match the PHP  package to MySQL 5.0.77
• Create a privileged MySQL user. (Any user may log in without  a password to get an anonymous session: “No Privileges”. Mac OS X user account – or _mysql. At this stage  log in without a password.)
  • phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as a single database. To accomplish the latter you’ll need a properly set up MySQL user who can read/write only the desired database. It’s up to you to look up the appropriate part in the MySQL manual.
• Ye-har! Who’d of guessed… Apple’s MySQL documentation was where to find simple instructions for how to give the MySQL root user a password – and hence succeed to log inwith privileges. Terminal command: /usr/local/mysql/bin/mysqladmin -u root password sniggle. Where sniggle is your choice for a secure password.
• For each DB user you should add that user with an MySQL query:
  CREATE USER 'user1'@'localhost' IDENTIFIED BY'pass1';

Update…

Couple of additions:

Add the time zone

Insert date_default_timezone_set('Europe/Madrid') ; into the PHP block Just above $today = date("j F Y, G:i:s"); to set the time zone (a requirement for PHP5 I believe)

Add a recipient switch

I’ve added a recipient switch (not actually a PHP Switch but a bunch of if elseif else statements) to this so that the email message is sent to different e-mail accounts according to the server host name. This keeps my dev tests and snafus away from clogging up the client’s email.
