Conventions

In this book, you will find a number of styles of text 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: "Controlling OpenStack Object Storage services is achieved using the tool called swift-init."

A block of code is set as follows:

account-server: bind_port = 6000
container-server: bind_port = 6001
object-server: bind_port = 6002

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[swift-hash]
# Random unique string used on all nodes
swift_hash_path_prefix=a4rUmUIgJYXpKhbh
swift_hash_path_suffix=NESuuUEqc6OXwy6X

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

sudo swift-init all start
sudo swift-init all stop
sudo swift-init all restart

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "An important field is the Common Name field."

Note

Warnings or important notes appear in a box like this.
