问题
OSX machine running MAMP. CakePHP 2.2.1 installed and configured properly (meaning that I have all green bars when I browse to the Index.php file, I have completed the Blogs tutorial and am working on my second app with which scaffolding is up and running). Now I am trying to Bake for the first time.
Per the cookbook (and others), I installed a fresh copy of cake into a directory (my users directory) and then put the path variable in my .bash_profile file
export PATH="$PATH:/Users/p_scott/cake221/app/Console"
after which I was able to go into Terminal, type cake and have the console come up. You can see that up to that point, I was invoking the console from the app directory.
I first tried running cake bake from the terminal using the -app parameter and designating the path to my practice apps. The first time I did this, I got the following
Welcome to CakePHP v2.2.1 Console

No matter what I put in for the database (if I leave it blank, it asks me again), but any answer gives me the following error:
Warning Error: PDO::__construct(): [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) in [/Users/p_scott/cake221/lib/Cake/Model/Datasource/Database/Mysql.php, line 149]

Once I started getting this error, I tried navigating in terminal to the <cake install dir>/app/Console folder and the <different instance of cake install dir>/app/Console folder to try the console from within my app/s. I either get the same errors or it asks me different questions, like:
What is the path to the project you want to bake?
[/Users/p_scott/myapp] > /Applications/MAMP/htdocs/history/app
What is the path to the directory layout you wish to copy?
[/Applications/MAMP/htdocs/history/lib/Cake/Console/Templates/skel] >
PHP CLI is installed and it appears to be working
PHP 5.3.8 (cli) (built: Dec 5 2011 21:24:09)
Copyright (c) 1997-2011 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2011 Zend Technologies
My PDO support appears to be enabled. In terminal I typed:
php --ri pdo
PDO
PDO support => enabled
PDO drivers => mysql, sqlite, sqlite2
I don't have a php.ini file in Apache (because I am on a Mac), but the one in the PHP 5.36 directory, I have the following extensions enabled:
extension=imap.so
extension=yaz.so
extension=mcrypt.so
extension=gettext.so
extension=pgsql.so
extension=pdo_pgsql.so
extension=pdo_mysql.so
After taking a break, I found an article
(http://www.dereuromark.de/2011/10/31/freshly-baked-cake2-0-tips/) that talks about a change of console location in 2.0. I should try using it from that location (<cake installed dir>/lib/Cake/Console ). Once I tried this, I either got the questions about what layout I wanted to use or... ONCE, I was able to get the bake application to ask me to create a database configuration. I went through the steps and it pooped out this error at the end:
Fatal error: Class 'DATABASE_CONFIG' not found in /Applications/MAMP/htdocs/history/lib/Cake/Console/Command/Task/DbConfigTask.php on line 264
Which leads me to one more piece of info. This is my default DB configuration in the <cake installation dir>/history/app/Config/database.php file.
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'cakeHistoryUser',
'password' => 'cakeHistoryPassword',
'database' => 'cake_history',
'prefix' => '',
//'encoding' => 'utf8',
);
Before posting this question (and all of this information), I spend some quality time out here and it seems like most of my issues are or CLI related but I just don't see where I need to change something and hours and hours later, I need some help.
Help me Obi Wan, you are my only hope
回答1:
The problem is you are trying to interact with the database via the command line, however the PHP-CLI is a different install than the one proveided by MAMP so it doesn't know about the database server.
Try changing localhost to 127.0.0.1 in your app/Config/database.php file and that should do the trick.
回答2:
Something like this happened to me, and the easiest way I found to make it work which I don't see here is changing localhost to 127.0.0.1 and adding the port number at the end, e.g., MAMP uses port number 8899, so:
"mysql:host=127.0.0.1:8889"
