Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The keystonerc_admin file thus becomes much more than just a storage place for the user's credentials."

A block of code is set as follows:

export OS_USERNAME=danradez
export OS_TENANT_NAME=danradez
export OS_PASSWORD=supersecret
export OS_AUTH_URL=http://192.168.123.101:5000/v2.0/
export PS1='[\u@\h \W(keystone_danradez)]\$ '

Any command-line input or output is written as follows:

mylaptop$ ssh root@192.168.122.101
control# yum update -y
control# yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
control# packstack --gen-answer-file myanswers.txt

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "When you click on the Create Project button, the Create User form will show up again with all your original data filled in for you and the new tenant's name populated for you."
