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: "This engine is a drop-in replacement for the FEDERATED engine. It uses libmysql to talk to an RDBMS."

A block of code is set as follows:

# -*- mode: ruby -*-
# vi: set ft=ruby :
ENV['LANG'] = 'C'

# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"

# Insert all your Vms with configs
boxes = [
    { :name => :mysqlserver },

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

  Replicate_Ignore_Server_Ids:
             Master_Server_Id: 1
               Master_SSL_Crl: /etc/mysql/ssl/cacert.pem
           Master_SSL_Crlpath:
                   Using_Gtid: No

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

MariaDB [(none)]> show global variables like 'tmp_table_size';
+----------------+----------+
| Variable_name | Value |
+----------------+----------+
| tmp_table_size | 33554432 |
+----------------+----------+
1 row in set (0.00 sec)

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: "With HP hardware, a Ctrl + A in the BIOS shows an additional Services Options menu."

Note

Warnings or important notes appear in a box like this.
