MAMP won’t start!

Problem:

I get this issue a lot. “My MAMP won’t start! … I’m trying to set up MAMP and it stays red.” What can you do?

Solution:

Whether it’s the dot next to Apache or the dot next to MySQL that’s red, probably the simplest thing to do is

1. Click: Preferences

2. Click the tab for “Ports”

3. Change the ports  to something else (or, if you have previously changed them from the default 8888 and 8889, click “Set to default Apache and MySQL ports”)

4. Quit and restart

If that doesn’t work, check to make sure that you’re not running web sharing:

  1. Go to Apple Menu > System Preferences… > Sharing > and uncheck “Web sharing”

If that doesn’t work… try this fix for MAMP when MySQL is not starting:

  1. Quit MAMP
  2. Open a terminal and type: killall -9 mysqld
  3. Restart MAMP

    The problem with OSX Montain Lion is that /usr/lib/libpq.5.3.dylib does not exist, but /usr/lib/libpq.5.dylib does.

    TO FIX THE ISSUE, OPEN TERMINAL AND:

    ~# sudo ln -s /usr/lib/libpq.5.3.dylib /usr/lib/libpq.5.dylib

    That’s it!

    When I have MAMP open and a local WordPress site active in a browser, and my computer (iMac) locks up or turns off, it seems to corrupt something and the mysql server will not start when I try it next time. I don’t see any other sql processes running in the Activity Monitor. I have tried deleting the files (not folders) in applications/mamp/db, but then my previous WordPress installation breaks.

    Any help would be appreciated.

      Don’t delete any files in the htdocs folders after a crash or anything else.

      Recommend you

      • Back up your htdocs folder
      • Download a fresh copy of MAMP
      • Delete old MAMP app from Applications
      • Install new MAMP app (basically copy to Applications)
      • Replace contents of htdocs with the contents of your backed up htdocs

      Also, remove, turn off, or otherwise delete any other XAMPP or whatever else apps you’ve got going on…
