Rbac in shell generates error message

Archives Agile Web Application Development with Yii1.1 and
1

Hi,

Following the book’s instructions in Chapter 8, I was able to open the Yii interactive tool and see Rbac in the list of available commands, but when I ran it, i got this error message, which I don’t understand and don’t know how to fix :( and I didn’t see this topic anywhere on the forum. I’m using MAMP on a Mac (this is my mysql path


/Applications/MAMP/Library/bin/mysql

) . Something about database problem but I haven’t had any trouble connecting to mysql up to this point.

Anyone have an idea?


USAGE

  rbac


DESCRIPTION

  This command generates an initial RBAC authorization hierarchy.


>> rbac

Can you try running


sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock

from "Terminal" (found in ~/Applications/Utilities), and then trying again? You will need to type in your password.

If any errors appear, please post them here.

3

when I ran the statement you suggested in my terminal, it said


ln: /tmp/mysql.sock: File exists

I then started the Yii interactive tool and ran the same Rbac command, and got the same error message as in my OP.

4

Ok, how about if you do


sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /var/mysql/mysql.sock

If you get an error saying /var/mysql doesn’t exist, then run


sudo mkdir /var/mysql

and then the code above again

5

I got this from running the statement in your last post


ln: /var/mysql/mysql.sock: File exists

and then when I ran Rbac in Yii interactive tool, I got same error message as in OP

Hmm, one more thing.

In your /protected/config/main.php file, where you have your ‘db’ settings array, try adding this to the end of the ‘connectionString’ property:


unix_socket=/Applications/MAMP/tmp/mysql/mysql.sock

I’m not familiar with MAMP, so most of what I’m advising is coming from this thread:

http://www.yiiframework.com/forum/index.php?/topic/6554-database-connection-issue/page__p__33532&#entry33532

It’s also been suggested that changing ‘localhost’ to ‘127.0.0.1’ in you ‘connectionString’ may solve the problem.

There were a number of solutions posted on that site, but I just tried changing localhost to ‘127.0.0.1’ and it worked. Thanks

If your using MAMP, then you might need to add he port number to the connection string.

eg

‘connectionString’ => ‘mysql:host=localhost;port=8889;dbname=testdrive’,
