在 Mac OSX 上使用 MAMP 时，如何让 CakePHP 烘焙以找

How do I get CakePHP bake to find mysql.sock and recognize MySQL while using MAMP on Mac OSX?(在 Mac OSX 上使用 MAMP 时，如何让 CakePHP 烘焙以找到 mysql.sock 并识别 MySQL?)

问题描述

我目前正在阅读 David Golding 的Beginning CakePHP:从新手到专业人士".有一次，我必须使用 CLI 命令蛋糕烘烤"，我会看到欢迎屏幕，但是当我尝试烘烤时，例如我收到以下错误消息的控制器:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) in/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 第 117 行警告:mysql_select_db():在第 122 行的/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 中提供的参数不是有效的 MySQL-Link 资源警告:mysql_get_server_info():在第 130 行的/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 中提供的参数不是有效的 MySQL-Link 资源警告:mysql_query():在第 154 行的/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 中提供的参数不是有效的 MySQL-Link 资源错误:您的数据库没有任何表.
我怀疑错误消息与 php 试图访问错误的 mysql-socket，即默认的 osx mysql-socket - 而不是 MAMP 使用的那个有关.因此，我更改了数据库配置以连接到 UNIX mysql-socket (:/Applications/MAMP/tmp/mysql/mysql.sock):
class DATABASE_CONFIG {var $default = 数组('司机' =>'mysql','连接' =>'mysql_connect','持久' =>错误的，'host' =>':/Applications/MAMP/tmp/mysql/mysql.sock',//UNIX MySQL-socket'登录' =>'我的用户','密码' =>'my_pass','数据库' =>'博客'，'前缀' =>'',);}
但是我收到了与新套接字相同的错误消息:
Warning: mysql_connect(): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock:3306' (2) in/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 第 117 行警告:mysql_select_db():在第 122 行的/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 中提供的参数不是有效的 MySQL-Link 资源警告:mysql_get_server_info():在第 130 行的/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 中提供的参数不是有效的 MySQL-Link 资源警告:mysql_query():在第 154 行的/Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php 中提供的参数不是有效的 MySQL-Link 资源错误:您的数据库没有任何表.
此外，即使我使用 MAMP 在欢迎屏幕上显示的 UNIX 套接字，当使用此套接字而不是 localhost 时，CakePHP 会丢失数据库连接.
关于如何让烘焙工作有任何想法?

谢谢你们帮我解决问题！:)
我在确定 my.cnf 中的何处进行编辑以使 MySQL 侦听 TCP/IP 请求时遇到问题.我能找到提到 TCP/IP 的唯一段落如下:
# 根本不监听 TCP/IP 端口.这可以是一个安全增强，# 如果所有需要连接到 mysqld 的进程都运行在同一台主机上.# 与 mysqld 的所有交互都必须通过 Unix 套接字或命名管道进行.# 请注意，在 Windows 上使用此选项而不启用命名管道#(通过enable-named-pipe"选项)将使mysqld无用！##skip-网络
这让我可以完全关闭 TCP/IP，这与我的意图相反.我不知道如何去做你的建议，如果你能更详细一点，那就太好了.我在这些事情上完全是 n00b :S
注册.连接到本地套接字:我删除了主机参数中的前导冒号，结果相同.
 解决方案 
从错误来看，它似乎正在尝试连接到实际 IP 地址而不是 UNIX 套接字，请看:
<前>'/Applications/MAMP/tmp/mysql/mysql.sock:3306'

它在套接字上附加了一个端口，这是错误的.

因此，我首先尝试配置 MySQL 以侦听 TCP/IP 请求(编辑 my.cnf 中的相应部分)并尝试提供 127.0.0.1 而不是套接字.

如果您不向下滚动:

要在 CakePHP 级别修复它，请将 database.php 上的主机更改为localhost"并添加一个端口指令，其值设置为套接字名称/Applications/MAMP/tmp/mysql/mysql.sock"

I am currently reading "Beginning CakePHP:From Novice to Professional" by David Golding. At one point I have to use the CLI-command "cake bake", I get the welcome-screen but when I try to bake e.g. a Controller I get the following error messages:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122

Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154
Error: Your database does not have any tables.

I suspect that the error-messages has to do with php trying to access the wrong mysql-socket, namely the default osx mysql-socket - instead of the one that MAMP uses. Hence I change my database configurations to connect to the UNIX mysql-socket (:/Applications/MAMP/tmp/mysql/mysql.sock):

class DATABASE_CONFIG {

    var $default = array(
        'driver' => 'mysql',
        'connect' => 'mysql_connect',
        'persistent' => false,
        'host' =>':/Applications/MAMP/tmp/mysql/mysql.sock', // UNIX MySQL-socket
        'login' => 'my_user',
        'password' => 'my_pass',
        'database' => 'blog',
        'prefix' => '',
    );

}

But I get the same error-messages with the new socket:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock:3306' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122

Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154
Error: Your database does not have any tables.

Also, even though I use the UNIX-socket that MAMP show on it's welcome-screen, CakePHP loses the database-connection, when using this socket instead of localhost.

Any ideas on how I can get bake to work?

-- Edit 1 --

Thank you guys for helping me out! :)

I have a problem figuring out where in my.cnf to edit to get MySQL to listen to TCP/IP request. The only paragraph I can find where TCP/IP is mentioned is the following:

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!
# 
#skip-networking

That allows me to turn off TCP/IP completely, which is the opposite of my intention. I don't know how to go about what you suggest, if you could be more elaborate it would be great. I am a total n00b on these matters :S

Reg. connecting to a local socket: I removed the leading colon in the host-parameter, same result.

From the error, it looks like it's trying to connect to an actual IP address and not a UNIX socket, look:

 '/Applications/MAMP/tmp/mysql/mysql.sock:3306'

It's appending a port to the socket, which is wrong.

So, I'd first try to configure MySQL to listen to TCP/IP requests (edit the proper section in my.cnf) and try providing 127.0.0.1 instead of the socket.

In case you won't scroll down:

To fix it at CakePHP level, change host on database.php to 'localhost' and add a port directive with its value set to the socket name '/Applications/MAMP/tmp/mysql/mysql.sock'
