我目前正在阅读 David Golding 的“CakePHP 入门:从新手到专业”。有一次我必须使用 CLI 命令“蛋糕烘焙”，我看到了欢迎屏幕，但是当我尝试烘焙时，例如 Controller 我收到以下错误消息:

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.

我怀疑错误消息与 php 试图访问错误的 mysql-socket 有关，即默认的 osx mysql-socket - 而不是 MAMP 使用的 mysql-socket。因此，我更改了我的数据库配置以连接到 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' => '',
    );

}

但是我在使用新套接字时得到了相同的错误消息:

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 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.

此外，即使我使用 MAMP 在其欢迎屏幕上显示的 UNIX 套接字，当使用此套接字而不是本地主机时，CakePHP 也会丢失数据库连接。

关于如何让 bake 工作有什么想法吗？

-- 编辑 1 --

谢谢大家帮助我! :)

我在确定 my.cnf 中的何处进行编辑以使 MySQL 监听 TCP/IP 请求时遇到问题。我能找到的唯一提到 TCP/IP 的段落如下:

# 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

这让我可以完全关闭 TCP/IP，这与我的意图相反。我不知道如何处理你的建议，如果你能更详细一点，那就太好了。在这些问题上我完全是 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。

最佳答案

我找到了这个问题的解决方案: 在cakephp app/config/database.php 文件中添加套接字配置

class DATABASE_CONFIG {

var $default = array(
    'driver' => 'mysql',
    'persistent' => false,
    'host' => 'localhost',
    'port' => '/Applications/MAMP/tmp/mysql/mysql.sock', // here is the key !
    'login' => 'you',
    'password' => 'yourpass',
    'database' => 'yourdb',
    'prefix' => '',

);

关于php - 在 Mac OSX 上使用 MAMP 时如何让 CakePHP bake 找到 mysql.sock 并识别 MySQL？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/366550/
