Ubuntu

Update Ubuntu

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

Install additional packages

sudo aptitude install build-essential zip git

MySQL

Install MySQL server and php5 MySQL module

sudo apt-get install mysql-server php5-mysql

Set the mysql root user password during the installation

Install the default MySQL databases

sudo mysql_install_db

Run the finisher script and respond every prompt with yes to get a secure MySQL installation

sudo /usr/bin/mysql_secure_installation

Connect to your new MySQL server

mysql -uroot -p

Enter the root password

And run this command to get the MySQL version

SHOW variables LIKE "%version%";

Nginx

Install Nginx

sudo apt-get install nginx

Create a Nginx site configuration file

sudo touch /etc/nginx/sites-available/wordpress.conf
sudo vi /etc/nginx/sites-available/wordpress.conf

Paste this config

server {    
listen   80;

    root /var/www/wordpress;
    index index.php index.html index.htm;

    server_name [example.com];

    location / {
        try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/www;
    }

    client_max_body_size 10M;

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    location ~ \.php$ {
        try_files $uri = 404;
        #fastcgi_pass 127.0.0.1:9000;
        # With php5-fpm:
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
}

Optionally you can rewrite false urls to a specified canonical url

server {
    listen       80;
    server_name  www.example.com  example.com;
    if ($http_host = www.example.org) {
        rewrite  (.*)  http://[example.com]$1;
    }
    ...
}

Create a symlink to the config file

sudo ln -s /etc/nginx/sites-available/wordpress.conf /etc/nginx/sites-enabled/wordpress.conf

Restart Ngnix

sudo service nginx restart

Check Nginx version

nginx -v

PHP

Install PHP with FastCGI support

sudo apt-get install php5-fpm

configure PHP installaton

 sudo vi /etc/php5/fpm/php.ini

Find the line cgi.fix_pathinfo=1 by pressing ESC and enter

/;cgi.fix_pathinfo=1

Uncomment this line and change value to 0

cgi.fix_pathinfo=0

If this number is kept as 1, the php interpreter will do its best to process the file that is as near to the requested file as possible. This is a possible security risk. If this number is set to 0, conversely, the interpreter will only process the exact file path—a much safer alternative.

Find the line ; default extension directory. and insert below

extension=mcrypt.so

Update the listening port for the php fpm

sudo vi /etc/php5/fpm/pool.d/www.conf
Set listen = /var/run/php5-fpm.sock

Restart the service

sudo service php5-fpm restart

Create the website folder

sudo mkdir /var/www/wordpress

Add a PHP info file

sudo vi /var/www/wordpress/info.php

Set content

<?php
phpinfo();
?>

Open your browser on http://example.com/info.php

Delete this file if everything works

phpMyAdmin

Install phpMyAdmin

sudo apt-get install phpmyadmin

When phpMyAdmin prompts you to choose a server (either apache or lighttpd)hit tab, and select neither one.

When phpMyAdmin asks you wether to configure database for phpmyadmin with dbconfig-common. Chose and enter the MySQL root user password

Hit on the MySQL application password for phpmyadmin prompt.

Create a symbolic link for the phpMyAdmin website

sudo ln -s /usr/share/phpmyadmin/ /usr/share/nginx/www

Create a Nginx configuration file

sudo touch /etc/nginx/sites-available/phpmyadmin.conf
sudo vi /etc/nginx/sites-available/phpmyadmin.conf

Paste this config

server{
    listen 80;

    server_name [Your Public IP];
    root /var/www/;

    index index.php index.html index.htm;

    client_max_body_size 10M;

    location ~ .php$ {
        try_files $uri = 404;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include /etc/nginx/fastcgi_params;
    }
}

Create a symlink to the config file

sudo ln -s /etc/nginx/sites-available/phpmyadmin.conf /etc/nginx/sites-enabled/phpmyadmin.conf

Restart Ngnix

sudo service nginx restart

Open the browser on http://[YourPublicIP]/phpmyadmin/

WordPress

Open the WordPress site directory

cd /var/www/wordpress/

Download latest WordPress package and untar it

sudo wget http://wordpress.org/latest.tar.gz
tar -xzvf latest.tar.gz

Copy the untared files to the current folder and delete the other files

sudo cp -r ./wordpress/* ./
sudo rm -r wordpress
sudo rm latest.tar.gz

Let’s create the MySQL WordPress user

mysql -u root -p

Enter the MySQL root user password

Create the WordPress database

CREATE DATABASE wordpress;

Create the WordPress database user

CREATE USER wordpress@localhost;

Set the password for the WordPress database user

SET PASSWORD FOR wordpress@localhost = PASSWORD("[password]");

Grant WordPress user full access on WordPress database

GRANT ALL PRIVILEGES ON wordpress.* TO wordpress@localhost IDENTIFIED BY '[password]';

Refresh MySQL and exit

FLUSH PRIVILEGES;
exit

Copy the WordPress example config file

sudo cp wp-config-sample.php wp-config.php

Edit the config file

sudo vi wp-config.php

Set database, database user and his password

define('DB_NAME', 'wordpress');

define('DB_USER', 'wordpress');

define('DB_PASSWORD', '[password]');

Update permissions for Nginx user

sudo chown www-data:www-data * -R 
sudo usermod -a -G www-data www-data

Open the browser on http://example.com and install you WordPress blog
