I’ve tried using MAMP with PHP pages generated using Rapidweaver(don’t know PHP so this seeemed a good place to start). I’m trying to use a very simple contact form, but I get the following error in the PHP logfile:

PHP Notice: Undefined variable: tmp_name in /Applications/MAMP/htdocs/Sites/MFL/page11/files/mailer.php on line 25

Line 25 in the .php file has absolutely nothing to do with this:

I downloaded MAMP a few days ago, so I guess I’m running the latest version on an Intel iMac (10.4.8 with all the latest security updates running)

I have tried both PHP 4 and 5 from the widget, with the same results

I’m probably missing something very simple, but any pointers would be much appreciated!

Help!

A symbolic link in /tmp is not persistent across reboots. One can:
1. Create the symbolic link at the command line immediately before starting Apache and MySQL:

$ ln -s /Applications/mampstack-5.5/mysql/tmp/mysql.sock mysql.sock
$ /Applications/mampstack-5.5/mampctl.sh start apache
$ /Applications/mampstack-5.5/mampctl.sh start mysql

or

2. create a startup script to recreate it. To do this you create a simple shell script to do it and then set it to run at startup by editing /etc/ttys (after saving the original version)
(see the following links: http://docs.info.apple.com/article.html?artnum=301446 http://www.bombich.com/mactips/loginhooks.html)

or

3. Go with the BitRock solution in their email for the time being until release 5.6 is out with a fix for this.

I have used each of these approaches and can confirm that they work. It is not a big deal in any case. Simply pick what you prefer and go with it.

Thank you for interest in MAMPStack, and inform us of this problem.
You need run the mysql programs adding the following option:

–socket=/Applications/mampstack-5.5/mysql/tmp/mysql.sock

For example:
/Applications/mampstack-5.5/mysql/bin/mysqladmin
–socket=/Applications/mampstack-5.5/mysql/tmp/mysql.sock -p version

This is currently wrong in our documentation, but we have fixed this for
the next release of MAMPStack.

Thanks!

After the install, the Apache test went fine. Starting MySQL went fine. But verifying that it was up with the following:

Prompt> /Applications/mampstack-5.5/mysql/bin/mysqladmin -p
version

Returned the following:

/Applications/mampstack-5.5/mysql/bin/mysqladmin: connect to server at ‘localhost’ failed
error: ‘Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)’
Check that mysqld is running and that the socket: ‘/tmp/mysql.sock’ exists!

The configuration was looking in /tmp for the MySQL socket, which actually was to be found in:
/Applications/mampstack-5.5/mysql/tmp/mysql.sock

I cd’d to the /tmp directory and created a symbolic link to the actual location of the file:

ln -s /Applications/mampstack-5.5/mysql/tmp/mysql.sock mysql.sock

That provided the key link and everything worked.

It is as though the programs in /mysql/bin/ are hard-coded to look in /tmp for mysql.sock. They must be configurable but I haven’t figured it out yet. In any case, the symbolic link fix is simple and works even if it’s a bit of kludge.

Perhaps this would not be an issue with MAMP. But I think I had to deal with a similar issue during the install of MySQL 4 so it may be a more general issue.

I hope this is useful.

I would appreciate any advice.

Anytime you attempt to start a server engine such as mysql or apache, mamp or otherwise, there will typically be a log file recording errors that are encountered. Checking the log, in my experience, will nearly always point you in the direction of the specific problem that is causing the server not to start & stay running. The solution will often then be readily at hand, either by following your intuition and experimenting until the problem is solved, or by googling the error message or some portion of it, until you find the solution you’re looking for.

The MAMP 1.2.1 error logs for apache, mysql and php, are located in the MAMP folder, in a subfolder called ‘logs’. Open that folder and you’ll see the three relevant text files. In this case, open the mysql_error_log, and you’ll likely see a list of complaints for each time you’ve attempted to start mysql. Sometimes the list can be quite long, and it may seem to be very esoteric, but don’t let this put you off. Often times, one single problem will be reported over and over again throughout different stages of the server launch, or additional problems will be reported that are merely derived from the first problem. Fix the one problem, and many or all of the other errors are likely to go away.

Also, don’t worry about the fact that you might not understand much of the language reported in the error log. Just read over it line by line, grasping the parts you can and mentally setting aside the parts you don’t understand. Chances are, you’ll understand enough to locate the likely source of the problem. Do your research, try to restart the server, and check the bottom of the error log to see what has changed. Finally, the server will start right up and away you go.

If after all of this, you simply cannot find the solution, the best approach is usually to find a good related newsgroup, mailing list, or forum and post a summary of your question followed by the full details of your hardware, operating system & version, the software version you’re having trouble with, any solutions you’ve tried, and very importantly the full relevant portion of the log file(s). By supplying all of this detail, someone else will likely be able to understand your problem well enough to suggest a probably solution.

** Another important note: MAMP is a very cool packaged implementation of apache, mysql, and php, which works great right out of the box, but in order to achieve this level of simplicity, many of the related files, including log files, application files, conf files, etc., are located in non-standard places. This may have ramifications as you research answers to questions or problems, or if you later move to a more traditional implementation of these servers. Everything works the same, but things might be configured slightly differently, or located in a place different than some mentor might be suggesting you look. Just something to be aware of as you find your way around.

I hope this helps…
