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: "Most of these parameters are contained inside the php.ini file."

A block of code is set as follows:

zabbixsrv=zabbixsvr
[ -e /etc/sysconfig/$syscf ] && . /etc/sysconfig/$syscf

start()
{
    echo -n $"Starting Zabbix server: "

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

; Maximum size of POST data that PHP will accept.
; http://www.php.net/manual/en/ini.core.php#ini.post-max-size
post_max_size = 16M

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

# yum list postgres*

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: "Once we fill this form, we can click on Next."

Note

Warnings or important notes appear in a box like this.

Tip
