    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have [email protected] first in your PATH, run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> /Users/boolean/.bash_profile

For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"

For pkg-config to find [email protected] you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"


To restart [email protected] after an upgrade:
  brew services restart [email protected]
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/[email protected]/bin/mysqld_safe --datadir=/usr/local/var/mysql

Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
