In the beginning...
In the early days of website
development, the emphasis was on
designing the web pages around the
content. The site content was hard
coded in HTML. Supporting the server
required comprehensive webmaster
skills. The development of content
management systems (CMSes) changed
website design by separating the
content from the page code. In a CMS,
the web pages are fed content instead
of being embedded in the code, which
enables the content to be managed
with minimal skills.
An effective method for
understanding a CMS is to divide it
into two subsystems: one is content
management. The components used
in the management subsystem enable
creating, organising, modifying and
deleting website content. The other
subsystem is content gathering that
publishes content to the web and
manages workflow.
Configuring and install WordPress
REBOOT YOUR SERVER
1
Kick off a reboot of the server, by
now, you must remember the shutdown
command for a restart. When the server
returns, open a web browser to access
the user front-end of the CMS system
by entering the URL http://webpi. The
WordPress platform is designed to provide
step-by-step assistance in completing the
configuration. We are in the home stretch
now, select the ‘Let’s Go’ radio button and
proceed.
GENERATE YOUR CONFIG
2
Fill in the question fields with the
configuration data used for setting up
the MySQL database. If you don’t recall
them, the details are in the screenshot
(above). After completing the fields,
select the ‘Submit’ button. Using the
details provided, WordPress generates
the contents for the configuration file
/home/pi/www/wp-config.php .
It wouldn’t be able to write the contents to
a file so it will stop and ask for assistance.
CREATE ADMIN ACCOUNT
3
Create the file listed above using
the CLI. Copy the contents from the screen
and deposit them to the file. When the
file is saved, go back to the web screen
and select the button to run the install.
WordPress will return a welcome screen.
The details for this screen are needed to
create an account that can log into the
web server admin front-end and make
web design configuration changes in
the back-end.
INSTALL WORDPRESS
4
The first question asks to create a title
for the website. Use the details from the
screenshot to complete the form to put
the final touches to the CMS config. Select
Install ‘WordPress’ button on the bottom
of the screen. The success screen will
appear in a short while. You can’t log in on
the success screen, even if it looks like you
can. To log in drop the URL http://webpi/
wp-admin into your browser.
DESIGN YOUR SITE
5
Now use the credentials you’ve
created (wpadmin) to log in and start
designing a CMS website using WordPress.
Access the user content published by the
web server via a browser. The configuration
tools for WordPress are also available
via a web browser. The CMS site is built
to display the content to browser users
by sourcing content data from a relational
database.
CONTENT FLOW
6
Content is displayed by publishing
to the web server’s front-end (http://
webpi). In the back-end of the web server,
there are many components working
together to publish the content. The
configuration of the website is controlled
by an administrator accessing the back-end
functions via the web server administrator
front-end (http://webpi/wp-admin).
