I am doing an install of a mysql system, and decided that I needed to
change some things like host name. So I have to go back to square one
with the mysql setup, but can't find any instructions for this. I TRIED:
mysql_install_db
And it did SOMETHING, but
mysqladmin -u root password 'mypass'
failed with:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
I tried 'yum reinstall mysql' and that did not help
why should "yum reinstall" change anything?
Some apps reinit there data on reinstalls. Some don't. Don't know
until you try.
the daemon specific data are below /var&/lib/mysql as for
any other software they live below /var/ib/appname
no command ever will reset them besides rm -rf /var/lib/mysql/
but what has that all to do with change the hostname?
Don't know what changing the hostname did or does not do. I am digging
into various info to figure out what to delete or rebuild to get back to
pristine mysql. I can understand why this should not be easy - for
someone to remove all of your mysql data, but it should be possible...
