11/9/2015

Raspberry Pi is mostly ready for use after the basic configuration completed in my previous posts:

The next cool thing to do is to install wordpress on it. This post is just used to record all steps I have followed online instruction installed an instance of a WordPress site to run on Raspberry Pi using the Apache Web Server. There are a lots of more things you may like to know regarding Apache, PHP, Mysql. It is best to search other online resources or take a look those listing at the Reference section to find out more.

1. Check system update

sudo apt-get update && sudo apt-get upgrade

Choose Y if there is any update.

2. Install Apache2

sudo apt-get install apache2 -y

hostname -I

Get the ip address your Raspberry Pi

Open http://<IP> to confirm apache is working. It show the /var/www/index.html in your browser.

3. Install php5

sudo apt-get install php5 libapache2-mod-php5 -y

create a test index.php file

cd /var/www
sudo echo "<?php phpinfo(); ?>" | sudo tee index.php

verify php has been installed properly by using curl command.

pi@raspberrypi /var/www $ curl http://127.0.0.1/index.php

4. Install mysql database server.

sudo apt-get install mysql-server

During installation of mysql, you will be asked to provide root password.

5. Download wordpress and install it under /var/www/wordpress folder

cd /var/www
sudo chown pi: .
sudo rm *
wget http://wordpress.org/latest.tar.gz

tar xzf latest.tar.gz
//mv wordpress/* .
rm -rf wordpress latest.tar.gz

6. Create wordpress database from mysql command line

mysql -uroot -ppassword
mysql> create database wordpress;
Query OK, 1 row affected (0.00 sec)

7. Open URL "http://<IP>/wordpress" in the browser to start configure Wordpress

During installation wizard, fill out the basic site information as follows:

Database Name:      wordpress
User Name:          root
Password:           <YOUR PASSWORD>
Database Host:      localhost
Table Prefix:       wp_

During configuration Wordpress site, there is a problem to write wp-config.php file. To resolve this issue, you will have to manually create it with the contents showing above in the browser.

cd /var/www/wordpress
nano wp-config.php

Paste the copied text from browser into this file, and save and exit with Ctrl + X, then Y for yes and Enter.

Hit Run the install button to continue the installation. The last step is to enter your wordpress site information.

After installation done, the browser will jump to http://<ip>/wordpress/wp-admin. You will need to provide wordpress site username and password to log into Dashboard to manage your new created site.

There is one tip for a problem which is when you are trying to install new plug-in in your Wordpress site, it will prompt a page to ask you ftp username, password and site address. It is because of wordpress folder's permission problem.

The easiest and fastest fix is :

cd /var/www
sudo chown -hR http:http wordpress

You can replace http user with pi user.
