I’m trying to setup up MySQL on mac os 10.6 using Homebrew by
brew install mysql 5.1.52.
Everything goes well and I am also successful with the
However when I try to connect to the server using:
/usr/local/Cellar/mysql/5.1.52/bin/mysqladmin -u root password 'mypass'
/usr/local/Cellar/mysql/5.1.52/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)'
I’ve tried to access
mysqladmin or mysql using -u root -proot as well,
but it doesn’t work with or without password.
This is a brand new installation on a brand new machine and as far as I know the new installation must be accessible without a root password. I also tried:
but I also get
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
I think one can end up in this position with older versions of mysql already installed. I had the same problem and none of the above solutions worked for me. I fixed it thus:
cleanup commands, unloaded the
launchctl script, then deleted the mysql directory in
/usr/local/var, deleted my existing
/etc/my.cnf (leave that one up to you, should it apply) and launchctl plist
Updated the string for the plist. Note also your alternate security script directory will be based on which version of MySQL you are installing.
brew remove mysql brew cleanup launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist sudo rm -rf /usr/local/var/mysql
I then started from scratch:
- installed mysql with
brew install mysql
ran the commands brew suggested: (see note: below)
unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
Start mysql with
mysql.server startcommand, to be able to log on it
Used the alternate security script:
launchctlsection from the brew package script output such as,
#start launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist #stop launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
--force bit on
brew cleanup will also cleanup outdated kegs, think it’s a new-ish homebrew feature.
Note the second: a commenter says step 2 is not required. I don’t want to test it, so YMMV!
