1.Question Description:
1.1 version: mysql-5.7.11-64
1.2 form: zip file
1.3 >mysqld --install (successfully)
1.4 you create a directory called "data" in the mysql package, and create a file my.ini and edit the code like 'datadir...' ,
1.5 >net start mysql
you will see
2. Solution:
2.1 uninstall the mysql clearly
2.1.1 >mysqld --remove
2.1.2 delete the mysql directory
2.1.3 delete the regedit(http_local_machine)
2.2 extract the mysql zip again,
if your operation system is windows 2008 , you should extract the zip to the location where you can create directory without authirization(administrator role),
because when you executor the command mysqld --initialize, you may see the error info: can't create the directory.....
2.3 >mysqld --initialize
3. Thinking
3.1 there are some solutions like copy data folder from version 5.6 to version 5.7;
3.2 create my.ini file and cancel the comment "basedir","datadir..";
Don't Mysql know that ??
as the solution 2.3 show, we only need to executor the command "mysqld --initialize".
So we should read the doc of the software first rather than read A or B in the web site.
