Wordpress

WordPress is a free and open source software blogging and content management tool which requires Apache2, php5 ja mysql.

Installation

First we install a LAMP server (Linux, apache2, php5, mysql). We also install the phpmyadmin tool which simplifies MySQL management.

aptitude install apache2 php5 mysql-server phpmyadmin

Create passwords if so prompted.

Phpmyadmin configuration

We go to the address "serveripaddress/phpmyadmin" and from there to privileges -> add a new user and select a correct username, host (local) and password. I also chose "Create database with same name and grant all privileges", then create a user.

Apache2 configuration

I want to create wordpress for a user called johannes. Thus I make johannes his own webpages into his own /home directory using userdir.

a2enmod userdir

service apache2 reload

mkdir /home/johannes/public_html

Installation and configuration of wordpress

Fetch the wordpress package:

cd /home/johannes/public_html/
wget https://wordpress.org/latest.tar.gz
tar -zxvf latest.tar.gz
ls

Using the Ls command the wordpress directory should now be visible.

In this phase as you try to go to http://ownaddress/~johannes/wordpress/ you will most likely be met with an error: php is not visible. It is caused by blocks defined in the php5 userdir directories. To fix it: nano /etc/apache2/mods-enabled/php5.conf

Comment the line below

#        php_admin_value engine Off

service apache2 reload

Now it should look better. Correct information: (the user and database which we created with phpmyadmin).

You will now get an error message. Create a configuration file and copy the following there:

nano /home/johannes/public_html/wordpress/wp-config.php

Copy the text visible in your browser into that file, save it and then select "Run the Install".

You can also give the www-data user to write in the wordpress directory, which eases the installation a bunch:

 chown www-data %wordpressdir%/config

Then just "install WordPress"

Now the blog is done. From the address http://serveripaddress/~johannes/wordpress/wp-admin/ you can find the control panel and from http://serveripaddress/~johannes/wordpress/ the site itself.

Adding pictures

We go to the control panel and select Media and then Add New. For me the site gives an error, "Unable to create directory wp-content/uploads/2014/09. Is it's parent directory writable by the server?"

We could of course put chmod 777 for the location in question, but that might not be very smart. Thus we do this ->

cd /home/johannes/public_html/wordpress/
sudo chown -R www-data wp-content
sudo chmod -R 755 wp-content

Now it should work.
