  • 772

I today install SP1 on my Windows Server 2008 R2, but after the mandatory reboot are the MySQL server unable to start, where i get the following error.

C:\Users\Cronjob>"C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld" --defaults
-file="C:\Program Files\MySQL\MySQL Server 5.1\my.ini"
110411 17:51:28 [Warning] '--default-character-set' is deprecated and will be re
moved in a future release. Please use '--character-set-server' instead.
110411 17:51:28 [Note] Plugin 'FEDERATED' is disabled.
110411 17:51:28  InnoDB: Operating system error number 5 in a file operation.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory. It may also be you have created a subdirectory
InnoDB: of the same name as a data file.
InnoDB: File name .\ibdata1
InnoDB: File operation call: 'open'.
InnoDB: Cannot continue operation.

I have tryed to remove the "read only" on the data dir "C:\ProgramData\MySQL\MySQL Server 5.1\data" but this dose not help.

    Looks like the file permissions got dropped by the service pack.

    1. Find which account is running the MySQL service by checking the "account" field in services.msc.
    2. Grant that account read/execute/modify permissions on the C:\ProgramData\MySQL directory.
    3. Make sure those rights inherit down to the files in the data directory.
