无法启动MySQL服务,报的错误：1067，进程意外终止（有图有真相）
问题表象：
我的mysql中的 my.ini文件配置：
#Path to installation directory. All paths are usually resolved relative to this. basedir="D:/software_builder/mysql/" #Path to the database root datadir="C:/ProgramData/MySQL/MySQL Server 5.5/Data/"
我在 datadir的路径下找到.err文件，查看错误原因

尝试过无数种网络搜索的解决方法，有过重装mysql的念头，也有过砸电脑的冲动，但最后还是天不负有心人，终于找到了解决方法；
第一步：在mysql的安装目录下 basedir=”D:/software_builder/mysql/的data文件夹里“D:software_buildermysqldata”” 下面还有一个mysql的文件夹（如图），
把“mysql文件夹”拷贝到数据库的数据存放位置的data文件夹下（我的是：C:ProgramDataMySQLMySQL Server 5.5data）
然后在服务里面启动mysql服务，结果：“I get it ！”
