Although Nginx is available for Windows since version 0.7.52, it is common knowledge that Linux- or BSD-based distributions are preferred for hosting production sites. During the various processes described in this book, we will thus assume that you are hosting your website on a Linux operating system, such as Debian, Ubuntu, CentOS, or other well-known distributions.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The rewrite and HTTP core modules of Nginx use PCRE for the syntax of their regular expressions, as we will discover in later chapters. You will need to install two packages—pcre and pcre-devel"

A block of code is set as follows:

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1

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

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1

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

apt-cache search nginx
apt-cache show PACKAGE_NAME
apt-get install PACKAGE_NAME

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
