mysql - 配置 wamp mysql 以使用 innodb 不工作 - 错误 123

Question

我在错误日志(wamp)中得到这个:

140205 22:57:41  InnoDB: Operating system error number 123 in a file operation.
InnoDB: Some operating system error numbers are described at
InnoDB: http://dev.mysql.com/doc/refman/5.1/en/operating-system-error-codes.html
InnoDB: File name C:\wampin\mysql\mysql5.5.8\data\ibdata1
InnoDB: File operation call: 'create'.
InnoDB: Cannot continue operation.

我不明白还能做什么，因为我取消了对命令的注释并适本地更改了路径:

# Uncomment the following if you are using InnoDB tables
innodb_data_home_dir = C:\wamp\bin\mysql\mysql5.5.8\data/
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = C:\wamp\bin\mysql\mysql5.5.8\data/
innodb_log_arch_dir = C:\wamp\bin\mysql\mysql5.5.8\data/
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 50M
innodb_additional_mem_pool_size = 10M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 50M
innodb_log_buffer_size = 80M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

请指教。

在您的配置文件中，您需要使用双反斜杠 (\\) 将路径指定为转义 Windows 样式路径，例如:

innodb_data_home_dir = C:\\wamp\\bin\\mysql\\mysql5.5.8\\data\\

在你的例子中，\b 被替换了，因为它是一个有效的控制代码，导致你的路径变得无效。我相信您也可以使用正斜杠 (/) 而不是双反斜杠 (\\)。
