Install Wordpress on nginx virtual host directory

This is the third part of setting up Wordpress on the top of Nginx web server using MySQL database. This all happens Raspberry Pi which uses Raspbian Jessie operating system.

It all began with:
1. nginx, php, virtual hosts, raspbian jessie, minimal
In this part I installed nginx and php module. I configured my router or windows machine so the DNS name 'wp.nginx' sends as forward to an IP address. I love this mechanism so much :)

2. Create MySQL database, non-root user, permissions
It is nice practice to run 'wpdb' database with different user than root. I call this use 'wpuser' and assign for it its own password. Also I need to let MySQL database engine from what location I can run MySQL queries and so. here comes 'localhost' in place.

And now the final block to install Wordpress

#!/bin/bash
#this is tested on fresh 2016-09-23-raspbian-jessie-lite.img
#sudo su
#apt-get update -y && apt-get upgrade -y && apt-get install git -y
#git clone https://github.com/catonrug/wordpress-install-raspbian-jessie-mysql-nginx-virtual-hosts.git && cd wordpress-install-raspbian-jessie-mysql-nginx-virtual-hosts && chmod +x *.sh
#nginx and php5-fpm must be installed, virtual hosts must be configured see more at 1-nginx-php-install.sh
#MySQL database 'wpdb', MySQL user 'wpuser' with password 'HAL3jpz4v7xzvGLZ' must exist. see more at 2-mysql-install-wordpress-database.sh
#./3-wordpress-install-nginx-mysql.sh

#move to virtual host directory
cd /var/www/wp.nginx

#remove everything
rm -rf *

#download latest WordPress
wget https://wordpress.org/latest.tar.gz

#extract and remove the archive
tar xzvf latest.tar.gz && rm latest.tar.gz

#move to wordpress directory
cd wordpress

#move all content to the parent directory
mv * ..

#move back
cd ..

#remove WordPress dir
rm -rf wordpress

#install adition libraries for wordpress
apt-get install php5-curl php5-gd libssh2-php -y

#to improve php5-fpm performance install cacher
apt-get install php-apc -y

#nginx service is runned by www-data user
#lets allow Nginx service to really change the content in WordPress dir
#this will allow us to do the default WordPress wizard using the web interface
chown -R www-data:www-data /var/www/wp.nginx

#restart config file for php and nginx
/etc/init.d/php5-fpm reload && /etc/init.d/nginx reload

#everything done
#i can go to wp.nginx and folow the wizard
#at first it looks nginx is slower than apache, but after restart it server good

When I configure through web interface I use credentials:
