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
