Once you’ve installed Homebrew, insert the Homebrew directory at the top of your PATH environment variable. You can do this by adding the following line at the bottom of your ~/.bashrc file

export PATH=/usr/local/bin:/usr/local/sbin:$PATH

brew update && brew install mongodb --with-openssl

Create the data directory

mkdir -p /data/db

-p is for creating intermediate directories as required.

#####Set permissions for the data directory. Before running mongod for the first time, ensure that the user account running mongod has read and write permissions for the directory.

… To have launchd start mongodb at login:

ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

Then to load mongodb now:

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

Or, if you don’t want/need launchctl, you can just run:

mongod --config /usr/local/etc/mongod.conf


Installing Python on Mac OS X (Python 2.7, Homebrew, Pip, Setuptools & Virtualenv) Upgrading Python to v3.x



wget https://bootstrap.pypa.io/get-pip.py && python get-pip.py


sudo pip install -U pip

If setuptools (or distribute) is not already installed, get-pip.py will install setuptools for you.

Pip is worth using over easy_install for its uninstall capabilities alone, but I should mention that pip is actively maintained while setuptools is mostly dead.



curl https://bootstrap.pypa.io/ez_setup.py -o - | python


pip install -U setuptools



sudo pip install virtualenv

Installing MySQL

  • brew doctor and fix any errors
  • brew update update packages
  • (optional) run upgarde brew upgrade afterwards. upgrade might take some time
  • brew install mysql install mysql
  • unset TMPDIR
  • mysql_install_db --verbose --user=whoami --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
  • mysql.server start
  • run the commands Brew suggests, add MySQL to launchctl so it automatically launches at startup

mysql should now work and be running all the time as expected


To connect:

mysql -uroot

To have launchd start mysql at login:

ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents Then to load mysql now:

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist Or, if you don't want/need launchctl, you can just run:

mysql.server start

To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system

Set password:

/usr/local/opt/mysql/bin/mysqladmin -u root password 'new-password'
/usr/local/opt/mysql/bin/mysqladmin -u root -h Serenity.local password 'new-password'

Alternatively you can run:


which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers.

Start/Stop/Restart MySQL: mysql.server start, mysql.server stop and mysql.server restart

See option: brew info mysql

#Other Tools

wget brew install wget nano brew install nano tree brew install tree GRC brew install grc and then

echo 'source "`brew --prefix grc`/etc/grc.bashrc"' >> ~/.bash_profile so new shell sessions start using GRC.

install all tools in one go with the following command:

brew doctor && brew update && brew upgrade && brew install wget && brew install nano && brew install tree && brew install grc && echo 'source "`brew --prefix grc`/etc/grc.bashrc"' >> ~/.bash_profile
