Workaround for when MAMP fails to stop or start

Last night there were several brownouts, which may or may not affected how my laptop slept. A rare sleep disorder causes problems when waking up: Right after opening my machine, it spontaneously reboots rather than, er, staying awake. This occurred only once or twice in the past year, but when it did, MAMP passed away into a zombie state. I couldn’t stop the servers; nor could I start them! Its Dashboard widget just spun and spun and spun, and I couldn’t access my local WordPress or Zenphoto installations; nor could I access the MAMP start page or phpMyAdmin. Shutting down my MacBook Pro and restarting it didn’t help either. Time to research and document the problem. >:-)

It turns out that this is a known bug, and that it’s on the MAMP developer list to fix. Even better, there’s a workaround:

  1. Start the MAMP application (something I rarely do), located in /Applications/MAMP/ The start page will open a new web browser page, but will fail to connect, which is expected since it’s in an unhappy state.
  2. Click the Preferences button.
  3. In the resulting Preferences sheet, don’t change anything. Just click the OK button.
  4. Results: The Apache and MySQL servers will stop and restart. Correctly, this time, rather than spinning infinitely. To make sure things are working, click the Open Start Page button; the MAMP start page should then load in a new browser page.
  5. If the Dashboard widget still continues to spin, just click its Stop Servers button, wait for the servers to stop completely, then click Start Servers.

I still use MAMP v1.7, but I’m guessing that the current version 1.7.1, released sometime late last year, also has this bug.

Before I applied the above workaround, I saw the following in the Console, while tracking systemp.log as I (unsuccessfully) attempted to stop and restart via the MAMP Dashboard widget:

2/18/08 11:11:27 AM authexec[224] executing /bin/sh
2/18/08 11:11:30 AM DashboardClient[141] apache didn't stop -> kill
2/18/08 11:11:30 AM [0x0-0xb00b][111]
2008-02-18 11:11:30.463 DashboardClient[141:10b] apache didn't stop -> kill
2/18/08 11:11:30 AM authexec[229] executing /bin/kill
2/18/08 11:11:30 AM [0x0-0xb00b][111] kill: 272: No such process
2/18/08 11:11:35 AM [0x0-0xb00b][111] /Applications/MAMP/Library/bin/mysqladmin: connect to server at 'localhost' failed
2/18/08 11:11:35 AM [0x0-0xb00b][111] error: 'Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock' (61)'
2/18/08 11:11:35 AM [0x0-0xb00b][111] Check that mysqld is running and that the socket: '/Applications/MAMP/tmp/mysql/mysql.sock' exists!

The message about failing to connect to localhost caught my attention, and searching for those terms in the MAMP forums yielded the workaround. After things got back into a happier working condition, I skimmed to find the message below, confirming that things (or, at least MySQL) are running:

Feb 18 11:49:36 Macintosh-2 [0x0-0x26026][290]: Starting mysqld daemon with databases from /Applications/MAMP/db/mysql

Sure enough, Apache, MySQL and PHP run fine now: I can use WordPress and Zenphoto again, as well as access phpMyAdmin.

    I have had this problem intermittently over the last year or so. I always ended up uninstalling and reinstalling MAMP to try to fix the problem. THANK YOU for this workaround as it saved me the headache of backing up all of my files before re-installing.

    Great tip… but it didn’t work for me. I think I might have killed my MAMP Apache installation!

    I had been playing with the allow/deny directives in httpd.conf, and stopping and starting the servers quite a bit.

    Now only MySQL will start, and even with this trick, Apache refuses to do anything.


    Does anyone have any ideas?

    Me again. I’ve figured it out!

    I also checked my Console, which told me I had a syntax error in my httpd.conf file.

    I had:

    Order allow,deny
    Allow from 123.456.78.90
    Deny all

    instead of:
    Order allow,deny
    Allow from 123.456.78.90
    Deny from all

    It’s always something simpe! Time for a cup of coffee, I think.

    Thanks again for the great workaround.

    Hi again

    I am enjoying my noob Unix adventure… I have found that it was necessary to add the subnet mask address and the localhost address to my whitelist, to make sure things work.

    So now, my directive looks like this:

    Order deny,allow
    Deny from all
    Allow from 123.456.78.90/
    Allow from

    That means that only I can see stuff.

    I just need to add another “Allow from… ” line for a different IP address.

    I never associated a power cut with my MAMP issue until reading your article. My MAMP is broken AGAIN for the fourth time this year, sure enough we had a power cut this morning. This workaround has saved me yet another complete re-install – thanks

    Thank you! Thank you! I’ve run into this problem whenever my Mac freezes and I have had to force a restart – which is not very often, but annoying nonetheless when I restart and find that MAMP doesn’t work. My Mac just froze up today, and thanks to your tip, I was able to get MAMP back up and running again without fiddling around with it for ages.

    The above method did not work for me, however, I found another way. In preferences, I clicked OK, but the window would not close or do anything.

    On the dashboard widget, I clicked on the ‘i’ which allowed to choose between php5 and php4. I chose php4, then switched it back to php5. My MAMP is ok now.

    Even unistalling MAMP (I Used APPDelete to be sure to remove all files and dependencies) i cannot get Apache up.
    Only MySQL starts up.

    Tried any configuration in Preferences already.

    Checked httpd.conf to match your suggestions…

    Any further suggestion would be very appreciated!

  38. This is great actually knowing how to get MAMP responding again.

    MAMP locked up on me a couple of months ago and I randomly did things until it started working again. Knowing what actually worked just saved me an hour of randomly trying stuff.

    If this workaround doesn’t work for you, you might just need to kill the mysqld process first. Open the MAMP application itself, then quit it to stop the Apache server if it’s still running, then open Terminal and type this:
