brew install mysql on mac os el capitan

Question

I'm trying to install mysql on MAC OS version 10.11.2 by following the methods in this link,

The following command has been successfully executed,

brew install mysql

but when I type the following command,

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

I get the following error:

mysql_install_db: [ERROR] unknown variable 'tmpdir=/tmp'
2015-12-17 17:35:54 [ERROR]   Unrecognized options

Please help. Thanks in advance.

Answer 1

Based on this link: https://bugs.launchpad.net/mysql-sandbox/+bug/1396092 and this https://blog.omgmog.net/post/installing-mysql-on-os-x-mountain-lion/ It looks like you may simply need to unset TMPDIR prior to running the install_db command.

Remove MySQL completely

1. ps -ax | grep mysql stop and kill any MySQL processes
2. brew remove mysql
3. brew cleanup
4. sudo rm /usr/local/mysql
5. sudo rm -rf /usr/local/var/mysql
6. sudo rm -rf /usr/local/mysql*
7. sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
8. sudo rm -rf /Library/StartupItems/MySQLCOM

Reinstall MySQL with Homebrew

1. brew doctor
2. brew update
3. brew install mysql
4. unset TMPDIR
5. mysqld -initialize --log-error-verbosity --user=whoami --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
6. mysql.server start
7. brew services start mysql

Answer 3

Try running this, it worked for me. (Got it from the comments found here)

mysqld -initialize --verbose --user=whoami --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

Posting here just in case anyone faced the same problem as me.
