This error because mysql is trying to connect via wrong socket file  try this command for MAMP servers  cd  var mysql  amp  amp  sudo ln -s  Applications MAMP tmp mysql mysql sock   or   cd  tmp  amp  amp  sudo ln -s  Applications MAMP tmp mysql mysql sock   and this commands for XAMPP servers      cd  var mysql  amp  amp  sudo ln -s  Applications XAMPP tmp mysql mysql sock   or      cd  tmp  amp  amp  sudo ln -s  Applications XAMPP tmp mysql mysql sock

It looks like mysql service is either not working or stopped  you can start it by using below command  in Ubuntu    service mysql start   It should work  If you are using any other operating system than Ubuntu then use appropriate way to start mysql

Im also suffered from this problem  amp  simply  by adding port number after the ip address saved me     dsn    mysql dbname sms messenger host 127 0 0 1 8889    user    root    password    root        This works for Mac OS  If you don t know your mysql port number  then You can easily find the port number on MAMP home page  OR  Type following command while running the MAMP server to switch the terminal into mysql  OMBP mamp Omal   Applications MAMP Library bin mysql --host localhost -uroot -proot   Then type   mysql gt  SHOW GLOBAL VARIABLES LIKE  PORT

Do not assume your unix socket which would be different from one to another  try to find it  First of all  get your unix socket location    mysql -u root -p  Enter your mysql password and login your mysql server from command line  mysql gt  show variables like   sock     --------------- ---------------------------------------    Variable name   Value                                    --------------- ---------------------------------------    socket           opt local var run mysql5 mysqld sock    --------------- ---------------------------------------   Your unix soket could be diffrent  Then change your php ini  find your php ini file from  lt   phpinfo     You maybe install many php with different version  so please don t assume your php ini file location  get it from your  phpinfo   Change your php ini  mysql default socket    opt local var run mysql5 mysqld sock  mysqli default socket    opt local var run mysql5 mysqld sock  pdo mysql default socket    opt local var run mysql5 mysqld sock  Then restart your apache or php-fpm

I would say that you have a problem connecting from PHP to MySQL     Something like PHP trying to find some socket file  and not finding it  maybe    I ve had this problem a couple of times -- not sure the error I got was exactly this one  though    If you are running some Linux-based system  there should be a my cnf file somewhere  that is used to configure MySQL -- on my Ubuntu  it s in  etc mysql    In this file  there might be something like this    socket    var run mysqld mysqld sock    PHP need to use the same file -- and  depending on your distribution  the default file might not be the same as the one that MySQL uses   In this case  adding these lines to your php ini file might help    mysql default socket    var run mysqld mysqld sock mysqli default socket    var run mysqld mysqld sock pdo mysql default socket    var run mysqld mysqld sock    You ll need to restart Apache so the modification to php ini is taken into account   The last one should be enough for PDO  which is used by Zend Framework -- but the two previous ones will not do any harm  and can be useful for other applications    If this doesn t help   can you connect to your database using PDO  in another script  that s totally independant of Zend Framework    i e  does something like this work  quoting      dsn    mysql dbname testdb host 127 0 0 1    user    dbuser    password    dbpass    try        dbh   new PDO  dsn   user   password     catch  PDOException  e        echo  Connection failed       e- gt getMessage        If no  the problem is definitly not with ZF  and is a configuration   installation problem of PHP   If yes    Well  it means you have a problem with ZF  and you ll need to give us more informations about your setup  like your DSN  for instance
