Installed [email protected] using brew mysql.server not a command

I think you need to start the service as well:

brew services start [email protected]

You can then check so the mysql service is running using:

brew services list

Now try to create symlinks for the mysql package:

brew link --force [email protected]

You might need to add the location to mysql to your path, to find the location of the package:

brew list [email protected]

Then add the location to the bin folder to the end of your ~/.profile or ~/.bash_profile file. For instance:

export PATH=$PATH:/usr/local/Cellar/[email protected]/5.6.41/bin

Then reload the file:

source ~/.bash_profile

Now you should be able to use the mysql and connect to the local running server.
