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: "Add 0.0.0.0/0 in the destination."
A block of code is set as follows:
#!/bin/bash
yum update -y
yum install -y httpd24 php56 mysql55-server php56-mysqlnd
service httpd start
chkconfig httpd on
groupadd
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
[root@ansible playbook]# vim awsvpc.yml
---
- name: Create VPC
hosts: localhost
gather_facts: no
roles:
- vpc
Any command-line input or output is written as follows:
mysql -u root -p
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: "Click on the button Create an AWS Account. "
