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 harden.yml performs hardening of MySQL server configuration" A block of code is set as follows:

- name: deletes anonymous mysql user
  mysql_user:
    user: ""
    state: absent
    login_password: "{{ mysql_root_password }}"
    login_user: root

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

- name: deletes anonymous mysql user
  mysql_user:
    user: ""
    state: absent
    login_password: "{{ mysql_root_password }}"
    login_user: root

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

ansible-playbook -i inventory playbook.yml
