64位win7下免安装版mysql 5.6（带memcached）安装配置问题详解（1067错误）

两年没接触程序开发了，最近在安装Mysql时碰到了一些问题，包括安装时无法启动（1067错误）。

免安装版加载为系统服务并设置为自启动，方法一直都没有改变，也非常简单，具体如下：

1. 开始菜单，运行“CMD”进入命令行模式，用“echo %WINDIR%”查看Windows目录，一般默认为“C:\Windows”；

2. 创建my.ini文件，放入系统的WINDIR目录，即C:\Windows\目录，内容如下：

[mysqld]

# set basedir to your installation path

basedir=E:/mysql

# set datadir to the location of your data directory

datadir=E:/mydata/data

basedir 为你的mysql压缩包解压路径，datadir为你存放的数据库文件路径。

然后进入你的mysql解压目录，安装mysql为系统服务，命令如下：

cd E:\mysql

E:

mysqld --install

最后运行mysql即可

net start mysql

成功启动后会提示：

MySQL 服务正在启动 .
MySQL 服务已经启动成功。

如果报1067错误，多半时你指定了一个新的数据库目录（本例：E:\mydata\data），但没有将原E:/mysql/data里面的文件拷贝到新目录下。另外也要注意你的系统是32位还是64位，要下载对应的版本。

停止mysql的命令如下：

net stop mysql

2.3.5.2. Creating an Option File

        If you need to specify startup options when you run the server,        you can indicate them on the command line or place them in an        option file. For options that are used every time the server        starts, you may find it most convenient to use an option file to        specify your MySQL configuration. This is particularly true        under the following circumstances:     

•             The installation or data directory locations are different            from the default locations (C:\Program            Files\MySQL\MySQL Server 5.6 and           C:\Program Files\MySQL\MySQL Server            5.6\data).

•             You need to tune the server settings, such as memory, cache,            or InnoDB configuration information.         

        When the MySQL server starts on Windows, it looks for option        files in several locations, such as the Windows directory,       C:\, and the MySQL installation directory        (for the full list of locations, see       Section 4.2.3.3, “Using Option Files”). The Windows directory typically        is named something likeC:\WINDOWS. You can        determine its exact location from the value of the       WINDIR environment variable using the        following command:     

C:\> echo %WINDIR%

        MySQL looks for options in each location first in the        my.ini file, and then in the        my.cnf file. However, to avoid confusion,        it is best if you use only one file. If your PC uses a boot        loader whereC: is not the boot drive, your        only option is to use themy.ini file.        Whichever option file you use, it must be a plain text file.     

        You can also make use of the example option files included with        your MySQL distribution; see       Section 4.2.3.3.2, “Preconfigured Option Files”.     

An option file can be created and modified with any text editor,        such as Notepad. For example, if MySQL is installed in       E:\mysql and the data directory is in        E:\mydata\data, you can create an option        file containing a [mysqld] section to specify        values for the basedir and       datadir options:     

[mysqld]
# set basedir to your installation path
basedir=E:/mysql
# set datadir to the location of your data directory
datadir=E:/mydata/data

        Note that Windows path names are specified in option files using        (forward) slashes rather than backslashes. If you do use        backslashes, double them:     

[mysqld]
# set basedir to your installation path
basedir=E:\\mysql
# set datadir to the location of your data directory
datadir=E:\\mydata\\data

        The rules for use of backslash in option file values are given        inSection 4.2.3.3, “Using Option Files”.     

The data directory is located within the        AppData directory for the user running        MySQL.     

        If you would like to use a data directory in a different        location, you should copy the entire contents of the       data directory to the new location. For        example, if you want to useE:\mydata as        the data directory instead, you must do two things:     

1.             Move the entire data directory and all            of its contents from the default location (for example           C:\Program Files\MySQL\MySQL Server            5.6\data) to           E:\mydata.         

2.             Use a --datadir option to            specify the new data directory location each time you start            the server.
