The same question is repeated again and again and i am another one repeating this question . I have already set up my mysql server . Its location is C:\Program Files\MySQL\MySQL Server 5.5 but i am not able to find the my.ini file inside the above path . When i type the command c:>mysql --help The output looks like
Default options are read from the following files in the given order: C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf C:\Program Files\MySQL\M ySQL Server 5.5\my.ini C:\Program Files\MySQL\MySQL Server 5.5\my.cnf The following groups are read: mysql client
But when I opened the above locations from where it is reading these files ,I am unable to locate the file . Can anyone tell me what is the exact way to retireve the my.ini file for WINDOWS?
To configure the client and utility applications, create a new my.ini file in the Windows installation directory. More info here
In MySQL 5.5 Windows the default path for my.ini is C:\ProgramData\MySQL\MySQL Server 5.5
You may need to change your file browser (windows explorer) options to show hidden files and directories.
I just checked my installation and located my.ini at C:\Program Files\MySQL\MySQL Server 5.5 which seems to be exactly the same like your installation path (and mysql version is the same for us). Are you sure it isn't there?
EDIT:
Possibly all you have to do is to rename one of example .ini files to my.ini (and optionally tune it to your needs), see: http://dev.mysql.com/doc/refman/5.1/en/option-files.html#option-files-preconfigured . These are: my-small.cnf, my-medium.cnf, my-large.cnf, and my-huge.cnf in your mysql installation dir. It is possible that this is just what I did in my case - it was a while ago when I installed mysql.
Under the Data folder my friend. Go one dir up from Mysql 5.5
Check variable datadir, in my default setup of 5.7 on Windows 7 it used:
C:\ProgramData\MySQL\MySQL Server 5.7
This has the whole content required for my.ini.
If you do not see my.ini file. Rename one of below file to my.ini
- my-huge.ini
- my-large.ini
- my-medium.ini
- my-small.ini
You can check the my.ini through the below process: 1. Through the command prompt. Type command as "Services.msc". 2. Go to MySQL56 service and right Click. Select Properties. 3. In the Properties area you will get the my.ini file path at the end.
I found the my.ini file by running SHOW VARIABLES LIKE "%datadir%"; and going one directory up.
